A Status LED is built into the 1243

window in the label on top of the controller. This Status LED displays fault

codes when there is a problem with the controller or with the inputs to the

controller. During normal operation, with no faults present, the Status LED

flashes steadily on and off. If the controller detects a fault, a 2-digit fault

identiﬁcation code is flashed continuously until the fault is corrected. For

example, code «3,2»—main contactor welded—appears as:

INSTALLATION AND WIRING
MOUNTING THE CONTROLLER
The controller can be oriented in any position, but the location should be
carefully chosen to keep the controller as clean and dry as possible. If a
clean, dry mounting location cannot be found, a cover must be used to
shield the controller from water and contaminants. When selecting the
mounting position, be sure to also take into consideration (1) that access is
needed at the front of the controller to plug the programmer into its connector,
and (2) that the built-in Status LED is visible only through the view port in the
label on top of the controller.
The outline and mounting hole dimensions for the 1243GEN2 controller
are shown in Figure 2. To ensure full rated power, the controller should be
fastened to a clean, flat metal surface with three 6 mm (1/4") diameter screws,
using the holes provided.

Controller
The mounting surface must be at least a 300×300×3 mm (12"×12"×1/8")
aluminum plate, or its equivalent, and subjected to a minimum 3 mph airflow
to meet the speciﬁed time/current ratings. Although not usually necessary, a
thermal joint compound can be used to improve heat conduction from the
controller heatsink to the mounting surface.
You will need to take steps during the design and development of your
end product to ensure that its EMC performance complies with applicable
regulations; suggestions are presented in Appendix A.
The 1243GEN2 controller contains ESD-sensitive components. Use
appropriate precautions in connecting, disconnecting, and handling the con-
troller. See installation suggestions in Appendix A for protecting the controller
from ESD damage.
Working on electric vehicles is potentially dangerous. You should
protect yourself against runaways, high current arcs, and outgassing from
lead acid batteries:
RUNAWAYS — Some conditions could cause the vehicle to run out of
control. Disconnect the motor or jack up the vehicle and get the drive
wheels off the ground before attempting any work on the motor control
circuitry.
HIGH CURRENT ARCS — Electric vehicle batteries can supply very high
power, and arcs can occur if they are short circuited. Always open the
battery circuit before working on the motor control circuitry. Wear safety
glasses, and use properly insulated tools to prevent shorts.
LEAD ACID BATTERIES — Charging or discharging generates hydrogen gas,
which can build up in and around the batteries. Follow the battery
manufacturer’s safety recommendations.
Wear safety glasses.

CONNECTIONS
Low Current Connections
A 16-pin Molex low current connector in the controller provides the low current
logic control connections:
2 — INSTALLATION & WIRING:
Controller
The mating connector is a 16-pin Molex Mini-Fit Jr. connector p/n 39-01-2165
using type 5556 terminals.
A 4-pin low power connector is provided for the handheld programmer. A
complete 1311 programmer kit, including the appropriate connecting cable,
can be ordered from Curtis.
The 4-pin connector can also be used for the Spyglass display. The display
is unplugged when the programmer is used.
High Current Connections
Three tin-plated solid copper bus bars are provided for high current connections
to the battery (B+ and B-) and the motor armature (M-). Cables are fastened to
the bus bars by M8 bolts. The 1243GEN2 case provides the capture nuts required

for the M8 bolts. The maximum bolt insertion depth below the surface of the
bus bar is 1.3 cm (1/2"). Bolt shafts exceeding this length may damage the controller.
The torque applied to the bolts should not exceed 16.3 N·m (12 ft-lbs).
Two 1/4" quick connect terminals (S1 and S2) are provided for the
connections to the motor ﬁeld winding.
WIRING: Standard Configuration
Figure 3 shows the typical wiring conﬁguration for most applications. For
walkie applications the interlock switch is typically activated by the tiller, and
an emergency reverse switch on the tiller handle provides the emergency reverse
signal.
For rider applications the interlock switch is typically a seat switch or a
foot switch, and there is no emergency reverse.

Standard Power Wiring
Motor armature wiring is straightforward, with the armature’s A1 connection
going to the controller’s B+ bus bar and the armature’s A2 connection going to
the controller’s M- bus bar.
The motor’s ﬁeld connections (S1 and S2) are less obvious. The direction
of vehicle travel with the forward direction selected will depend on how the
motor’s S1 and S2 connections are made to the controller’s two ﬁeld terminals
(S1 and S2) and how the motor shaft is connected to the drive wheels through
the vehicle’s drive train.
CAUTION:
The polarity of the S1 and S2 connections
will affect the operation of the emergency reverse feature. The forward and
reverse switches and the S1 and S2 connections must be conﬁgured so that the
vehicle drives away from the operator when the emergency reverse button is
pressed.
Standard Control Wiring
Wiring for the input switches and contactors is shown in Figure 3; the pins are
identiﬁed on page 6. In the standard wiring conﬁguration, the auxiliary driver
at Pin 8 is used to drive an electromagnetic brake.
The main contactor coil must be wired directly to the controller as shown
in Figure 3. The controller checks for welded or missing contactor faults and
uses the main contactor coil driver output to disconnect the battery from the
controller and motor when speciﬁc faults are present. If the main contactor coil
is not wired to Pin 4, the controller will not be able to open the main contactor
in serious fault conditions and the system will therefore not meet EEC safety
requirements.

Throttle
WIRING: Throttle
Wiring for various throttles is described below. They are categorized as Type 1,
2, 3, and 4 throttles in the program menu of the handheld programmer. Note:
In the text, throttles are identiﬁed by their nominal range and not by their actual
active range.
Appropriate throttles for use with the 1243GEN2 controller include two-
wire 5kΩ–0 throttles (“Type 1”); 0–5V throttles, current source throttles,
three-wire potentiometer throttles, and electronic throttles wired for single-
ended operation (all “Type 2”); two-wire 0–5kΩ throttles (“Type 3”), and
0–5V and three-wire potentiometer throttles wired for wigwag operation
(“Type 4”). The operating speciﬁcations for these throttle types are summarized
in Table 1. Refer to Section 3: Programmable Parameters, for information on
the effects of the Throttle Deadband and Throttle Max parameters on the
minimum and maximum throttle thresholds.
If the throttle you are planning to use is not covered, contact the Curtis
ofﬁce nearest you.

Notes: The Throttle Deadband and Throttle Max thresholds are valid for nominal 5kΩ
potentiometers or 5V sources with the default Throttle Deadband and Throttle
Max parameter settings of 0% and 100% respectively. These threshold values
will change with variations in the Throttle Deadband and Throttle Max param-
eter settings
.
The HPD thresholds are 25% of the active throttle range and therefore
dependent on the programmed Throttle Deadband and Throttle Max settings
(which define the active range).
The wiper voltage is measured with respect to B-.
The wiper resistance is measured from pot low to pot wiper. The potentiometer
must be disconnected from the controller when making this measurement.
* With a 0% Throttle Deadband setting, there is no neutral point on
a Type 4 throttle. A Throttle Deadband setting of at least 8% is
recommended for Type 4 throttles.

13XX programmer) is a 2-wire resistive throttle that connects between the Pot
Wiper and Pot Low pins (Pins 6 and 7), as shown in Figure 4. It doesn’t matter
which wire goes on which pin. For Type 1 throttles, zero speed corresponds to
5 kΩ measured between the two pins and full speed corresponds to 0 Ω. (Note:
This wiring is also shown in the standard wiring diagram, Figure 3.)

throttle (“Type 1”).
In addition to accommodating the basic 5kΩ–0 throttle, the Type 1
throttle is the easiest with which to implement a wigwag-style throttle.
Using a 20kΩ potentiometer wired as shown in Figure 5, the pot wiper can
be set such that the controller has 5 kΩ between Pins 6 and 7 when the
throttle is in the neutral position. The throttle mechanism can then be
designed such that rotating it either forward or back decreases the resistance
between Pins 6 and 7, which increases the controller output. The throttle
mechanism must provide signals to the controller’s forward and reverse
inputs independent of the throttle pot resistance. The controller will not
sense direction from the pot resistance.

Broken wire protection is provided by the controller sensing the current

If the Pot Low input current falls below 0.65 mA or its voltage below 0.06 V, a
throttle fault is generated and the controller is disabled. Note: The Pot Low pin

Throttle
0–5V, Current Source, 3-Wire Potentiometer,
and Electronic Throttles (“Type 2”)
With these throttles (“Type 2” in the programming menu) the controller looks
for a voltage signal at the wiper input (Pin 6). Zero speed will correspond to 0 V
and full speed to 5 V (measurements made relative to B-). A voltage source,
current source, 3-wire potentiometer, or electronic throttle can be used with this
throttle type. The wiring for each is slightly different and each has varying levels
of throttle fault detection associated with it.
0–5V Throttle
Two ways of wiring the 0–5V throttle are shown in Figure 6. The active range
for this throttle is from 0.2 V (at 0% Throttle Deadband) to 5.0 V (at 100%
Throttle Max), measured relative to B-.
Fig. 6 Wiring for
0–5V throttles (“Type 2”).
Sensor-referenced 0–5V throttles must provide a Pot Low current greater
than 0.65 mA to prevent shutdown due to pot faults. It is recommended that
the maximum Pot Low current be limited to 55 mA to prevent damage to the
Pot Low circuitry.
Ground-referenced 0–5V throttles require setting the Pot Low Fault
parameter (see Section 3, page 38) to Off; otherwise the controller will register
a throttle fault and will shut down. For ground-referenced 0–5V throttles, the
controller will detect open breaks in the wiper input but cannot provide full
throttle fault protection. Also, the controller recognizes the voltage between the
wiper input and B- as the applied throttle voltage and not the voltage from the
voltage source relative to the Pot Low input.
For either throttle input, if the 0–5V throttle input (Pin 6) exceeds 5.5 V
relative to B-, the controller will register a fault and shut down.

Curtis ET-XXX Electronic Throttle
The Curtis ET-XXX provides a 0–5V throttle and forward/reverse inputs for the
1243GEN2 controller. Wiring for the ET-XXX is shown in Figure 9. When an
electronic throttle is used, the Pot Low Fault parameter (see Section 3, page 38)
must be set to Off; otherwise the controller will register a throttle fault and will
shut down.
There is no fault detection built into the ET-XXX, and the controller will
detect only open wiper faults. It is the responsibility of the vehicle manufacturer
to provide any additional throttle fault detection necessary.
The ET-XXX can be integrated into a control head to provide wigwag-
style throttle control. Alternatively, a complete control head assembly is avail-
able from Curtis. This control head assembly—the CH series—combines the
ET-XXX throttle with a variety of standard control head switch functions for
use in walkie and lift truck applications.
0–5kΩ Throttle (“Type 3”)
The 0–5kΩ throttle (“Type 3” in the programming menu) is a 2-wire resistive
throttle that connects between the Pot Wiper and Pot Low pins (Pins 6 and 7)
as shown in Figure 10. Zero speed corresponds to 0 Ω measured between the two
pins and full speed corresponds to 5 kΩ. This throttle type is not appropriate
for use in wigwag-style applications.
Broken wire protection is provided by the controller sensing the current
flow from the wiper input through the potentiometer and into the Pot Low pin.
If the Pot Low input current falls below 0.65 mA or its voltage below 0.06 V,

Wigwag-Style 0–5V Voltage Source and 3-Wire Pot Throttle (“Type 4”)
These throttles (“Type 4” in the programming menu) operate in true wigwag
style. No signals to the controller’s forward and reverse inputs are required; the
action is determined by the wiper input value. The interface to the controller for
Type 4 devices is similar to that for Type 2 devices. The neutral point will be with
the wiper at 2.5 V, measured between Pin 6 and B-.
The controller will provide increasing forward speed as its wiper input
value (Pin 6) is increased, with maximum forward speed reached at 4.5 V. The
controller will provide increasing reverse speed as the wiper input value is
decreased, with maximum reverse speed reached at 0.5 V. The minimum and
maximum wiper voltage must not exceed the 0.5V and 4.5V fault limits.
When a 3-wire pot is used and the Pot Low Fault parameter (see Section 3,
page 36) is set to On, the controller provides full fault protection for Type 4
traction throttles. Any potentiometer value between 1 kΩ and 10 kΩ is sup-
ported. When a voltage throttle is used, it is the responsibility of the OEM to
provide appropriate throttle fault detection.
Note: If your Type 4 throttle has an internal neutral switch, this internal
neutral switch should be wired to the forward switch input (Pin 12). The
controller will behave as though no throttle is requested when the neutral
switch is high, and will use the throttle value when the neutral switch is low.
WIRING: Fault Outputs
The 1243GEN2 has two fault signal outputs (Pins 2 and 3), which can be used
to provide diagnostic information to a display panel. These current-sinking
outputs can drive LEDs or other loads requiring less than 10 mA. Since these
outputs are intended to drive LEDs, each contains a dropping resistor; as a
result, these outputs will not pull down to B-. Wiring is shown in Figure 11.
The Fault 1 and Fault 2 outputs can be programmed to display fault
information in either of two formats: Fault Code format or Fault Category
format (see Section 3, page 51).
Alternatively, Pin 2 can be used to provide a pump input signal (see pump
meter parameter, Section 3, page 48); Pin 3 can be used to interface an external
auxiliary enable circuit (see BDI lockout parameter, Section 3, page 51).

Emerg. Reverse and Aux Driver
☞
C A U T I O N
WIRING: Emergency Reverse
To implement the emergency reverse feature, Pin 13 (the emergency reverse
input) must be connected to battery voltage as shown in the standard wiring
diagram, Figure 3.
The controller provides maximum braking torque as soon as the emer-
gency reverse switch is closed. The vehicle will then be automatically driven in
the reverse direction at the programmed emergency reverse current limit until
the emergency reverse switch is released.
CAUTION:
The polarity of the S1 and S2 connections will affect the
operation of the emergency reverse feature. The forward and reverse switches
and the S1 and S2 connections must be conﬁgured so that the vehicle drives
away from the operator when the emergency reverse button is pressed.
WIRING: Emergency Reverse Check
An optional wire connected directly to the emergency reverse switch provides for
broken wire detection when that feature is programmed On (see Section 3,
page 43). The emergency reverse check output wire periodically pulses the
emergency reverse circuit to check for continuity in the wiring. If there is no
continuity, the controller output is inhibited until the wiring fault is corrected.
The emergency reverse check wire is connected to Pin 10 as shown by the
dotted line in the standard wiring diagram, Figure 3. If the option is selected
and the check wire is not connected, the vehicle will not operate. If the option
is not selected and the check wire is connected, no harm will occur—but
continuity will not be checked.
WIRING: Auxiliary Driver
The 1243GEN2 provides an auxiliary driver at Pin 8. This low side driver is
designed to energize an electromagnetic brake coil, as shown in the standard
wiring diagram (Figure 3). The output is rated at 2 amps and is overcurrent
protected. A coil suppression diode is provided internally to protect the driver
from inductive spikes generated at turn-off. The recommended wiring is shown
in the standard wiring diagram, Figure 3. The contactor coil or driver load
should not be connected directly to B+, which would cause the controller to be
always biased On via a path through the coil suppression diode to the KSI input.
Although it is typically used to drive an EM brake, the auxiliary driver can
be used to drive a pump contactor or hydraulic steering assist in applications
not requiring an EM brake.
Note: Because the auxiliary driver is typically used for an EM brake, the
programmable parameters related to this driver are described in the electromag-
netic brake parameter group; see page 28.
Curtis 1243GEN2 Manual
17
CONTACTOR, SWITCHES, and OTHER HARDWARE
Main Contactor
A main contactor should be used with any 1243GEN2 controller; otherwise the
controller’s fault detects will not be able to fully protect the controller and motor
drive system from damage in a fault condition. The main contactor allows the
controller and motor to be disconnected from the battery. This provides a
signiﬁcant safety feature in that the battery power can be removed from the drive
system if a controller or wiring fault results in full battery power being applied
to the motor. If the Contactor Diagnostics parameter (see Section 3, page 40)
is On, the controller will conduct a missing contactor check and a welded
contactor check each time the main contactor is requested to close and will not
proceed with the request if a fault is found.
A single-pole, single-throw (SPST) contactor with silver-alloy contacts,
such as an Albright SW80 or SW180—available from Curtis—is recom-
mended for use as the main contactor. The contactor coils should be speciﬁed
with a continuous rating at the nominal battery pack voltage.
The main contactor coil driver output (Pin 4) is rated at 2 amps, is over-
current protected, and is checked for open coil faults. A built-in coil suppres-
sion diode is connected between the main contactor coil driver output and the
keyswitch input. This protects the main contactor coil driver from failure due
to inductive voltage kickback spikes when the contactor is turned off.
Keyswitch and Interlock Switch
The vehicle should have a master on/off switch to turn the system off when not
in use. The keyswitch input provides logic power for the controller.
The interlock switch—which is typically implemented as a tiller switch,
deadman footswitch, or seatswitch—provides a safety interlock for the system.
The keyswitch and interlock switch provide current to drive the main
contactor coil and all other output driver loads as well as the controller’s internal
logic circuitry and must be rated to carry these currents.
Forward, Reverse, Mode Select, and Emergency Reverse Switches
These input switches can be any type of single-pole, single-throw (SPST) switch
capable of switching the battery voltage at 10 mA. Typically the emergency
reverse switch is a momentary switch, active only while it is being pressed.
Reverse Polarity Protection Diode
For reverse polarity protection, a diode should be added in series between the
battery and KSI. This diode will prohibit main contactor operation and current
flow if the battery pack is accidentally wired with the B+ and B- terminals
exchanged. It should be sized appropriately for the maximum contactor coil and
fault diode currents required from the control circuit. The reverse polarity
protection diode should be wired as shown in the standard wiring diagram,
Figure 3 (page 7).

Main Contactor & Switches, etc.

Circuitry Protection Devices
To protect the control circuitry from accidental shorts, a low current fuse
(appropriate for the maximum current draw) should be connected in series
between the battery and KSI. Additionally, a high current fuse should be wired
in series with the main contactor to protect the motor, controller, and batteries
from accidental shorts in the power system. The appropriate fuse for each
application should be selected with the help of a reputable fuse manufacturer or
dealer. The standard wiring diagram, Figure 3, shows the recommended location
for each fuse.
Mode Select Switch Operation
The two mode select switches (Mode Select 1 and Mode Select 2) together deﬁne
the four operating modes. The switch combinations are shown in Table 2.

Load Sensor [optional]
The 1243GEN2 provides a load sensor input at Pin 1. The controller can be
programmed to vary the strength of regen braking depending on the load sensor
input. The load sensor, if one is used, should be sized to handle your application’s
maximum expected load without exceeding 5 V.

3 — PROGRAMMABLE PARAMETERS
PROGRAMMABLE PARAMETERS
The 1243GEN2 controller has a number of parameters that can be programmed
using a Curtis handheld programmer. These programmable parameters allow
the vehicle’s performance characteristics to be customized to ﬁt the needs of
individual vehicles or vehicle applications.
The OEM can specify the default value for each parameter and can also
designate whether a parameter will have User or OEM access rights. Accord-
ingly, programmers are available in User and OEM versions. The User pro-
grammer can adjust only those parameters with User access rights, whereas the
OEM programmer can adjust all the parameters. For information about 1311
programmer operation, see Appendix B.
The MultiMode™ feature of the 1243GEN2 controller allows operation in
four distinct modes. These modes can be programmed to provide four different
sets of operating characteristics, which can be useful for operating in different
conditions, such as slow precise indoor maneuvering in Mode 1; faster, long
distance, outdoor travel in Mode 4; and application-speciﬁc special conditions
in Modes 2 and 3. Eight parameters can be conﬁgured independently in each
of the four modes:
— acceleration rate (M1–M4)
— braking current limit (M1–M4)
— braking rate (M1–M4)
— deceleration rate (M1–M4)
— drive current limit (M1–M4)
— maximum forward speed (M1–M4)
— maximum reverse speed (M1–M4)
— restraint (M1–M4).

3 — PROGRAMMABLE PARAMETERS:
Battery & Acceleration Parameters
VOLTAGE
The battery voltage parameter sets the overvoltage and undervoltage protection
thresholds for the controller and battery. Overvoltage protection cuts back
regenerative braking to prevent damage to batteries and other electrical system
components due to overvoltage; undervoltage protection prevents systems from
operating at voltages below their design thresholds. The battery voltage param-
eter can be set at 2 or 3, and should always be set to the system’s nominal battery
pack voltage:
NOMINAL
SETTING BATTERY PACK VOLTAGE
2 24V
3 36V
M1–M4, DRIVE C/L
The drive current limit parameter allows adjustment of the maximum current
the controller will supply to the motor during drive operation. This parameter
can be limited to reduce the maximum torque applied to the drive system by the
motor in any reduced performance mode. The drive current limit is adjustable
from 50 amps up to the controller’s full rated armature current. (The full rated
current depends on the controller model; see speciﬁcations in Table D-1.)
The drive current limit is tuned as part of the vehicle performance adjust-
ment process (Section 5).
M1–M4, ACCEL RATE
The acceleration rate deﬁnes the time it takes the controller to accelerate from
0% drive output to 100% drive output. A larger value represents a longer
acceleration time and a gentler start. Fast starts can be achieved by reducing the
acceleration time, i.e., by adjusting the accel rate to a smaller value. The
acceleration rate is adjustable from 0.1 to 3.0 seconds.
The acceleration rate is tuned as part of the vehicle performance adjust-
ment process (Section 5).
QUICK START
Upon receiving a sudden high throttle demand from neutral, the quick start
function causes the controller to momentarily exceed its normal acceleration
rate, in order to overcome vehicle inertia. The quick start algorithm is applied
each time the throttle passes through neutral and the controller is not in braking
Battery Parameter

Braking Parameters
mode. If the controller is in braking mode, the quick start function is disabled,
allowing normal braking to occur. Quick start is adjustable from 0 to 10.
Increasing the value will “liven” the vehicle’s acceleration response to fast throttle
movements.
The quick start parameter is tuned as part of the vehicle performance
adjustment process (Section 5).
NOTE: Quick start is not a MultiMode™ parameter, and its value will
therefore affect all four operating modes.
CURRENT RATIO
The current ratio parameter deﬁnes how much of the programmed drive
current will be available to the motor at reduced throttle requests. The current
ratio parameter can be set to 1, 2, 3, or 4. These settings correspond to the
following ratios:
SETTING RATIO
1 1 : 1
2 2 : 1
3 4 : 1
4 8 : 1
For example, with the current ratio set at 1 with 20% throttle requested, 20%
of the battery voltage and 20% of the drive current will be allowed to flow in the
motor (assuming a 50% throttle map setting). If the current ratio is set at 2
under these same conditions, 40% of the current will be available; if it is set at
3, 80%. The controller will not allow more than the programmed drive current
to flow in the motor. If the current ratio is set at 4 with 20% throttle requested,
the controller will allow only 100% of the drive current and not 160%.
High current ratio values will allow quicker startup response and im-
proved ramp climbing with partial throttle, but may cause too much jumpiness.
The current ratio parameter is tuned as part of the vehicle performance
adjustment process (Section 5).
Note: Current ratio is only effective in drive; it does not affect regen.
Curtis 1243GEN2 Manual
23
3 — PROGRAMMABLE PARAMETERS:
Braking Parameters
The seven Braking parameters affect the regenerative braking that is initiated when
the throttle is reduced or when the direction is reversed while the vehicle is being
driven. During regen braking, armature current flows toward the battery.
M1–M4, BRAKE C/L
The braking current limit parameter adjusts the maximum current the
controller will supply to the motor during regen braking. The braking current
limit is adjustable from 50 amps up to the controller’s full rated braking current.
(The full rated current depends on the controller model; see speciﬁcations in
Table D-1.) The braking current limit is tuned as part of the vehicle performance
adjustment process (Section 5).
M1–M4, DECEL RATE
The deceleration rate deﬁnes the time it takes the controller to reduce its
output to the new throttle request when the throttle is reduced or released. A
lower value represents a faster deceleration and thus a shorter stopping distance.
The decel rate deﬁnes the vehicle’s braking characteristic for any reduction in
throttle, including to neutral, that does not include a request for the opposite
direction. The decel rate is adjustable from 0.1 to 10.0 seconds. The decel rate
is tuned as part of the vehicle performance adjustment process (Section 5).
THROTTLE DECEL
The throttle deceleration rate parameter adjusts the rate at which the vehicle
transitions to braking when throttle is ﬁrst reduced. If the throttle decel rate is
set low, deceleration is initiated abruptly. The transition is smoother if the
throttle decel rate is higher; however, setting the throttle decel parameter too
high can cause the vehicle to feel uncontrollable when the throttle is released,
as it will continue to drive for a short period. The throttle decel rate is adjustable
from 0.1 to 1.0 second, with a value of 0.3 or 0.4 working well for most vehicles.
When the armature current goes negative (i.e., at the point when positive
torque transitions to negative torque), the normal decel rate goes into effect.
M1–M4, RESTRAINT
Because the 1243
GEN2 controller is conﬁgured to provide regenerative braking,
overspeed causes the controller to create a braking current and thus limit or
“restrain” the overspeed condition. The restraint parameter determines how
strongly the controller tries to limit the vehicle speed to the existing throttle
setting. It is applicable when throttle is reduced or when the vehicle begins to
travel downhill.

speed, which helps hold the vehicle from running away down ramps. The
higher the restraint parameter value, the stronger the braking force applied to
the motor and the slower the vehicle will creep down ramps. This creeping
speed depends on the restraint setting, the steepness of the ramp, and the
vehicle load weight. The restraint feature can never hold a vehicle perfectly
stationary on a ramp and is not intended to replace a mechanical or electromag-
netic brake for this purpose.
The restraint parameter establishes a linear mapping of ﬁeld current to
braking current, and is adjustable from the programmed minimum ﬁeld (Field
Min) up to the controller’s full rated ﬁeld current. As shown in Figure 13, it is
limited by the programmed maximum ﬁeld (Field Max). Setting the restraint
parameter to a high value will cause strong braking, in an effort to bring the
vehicle speed down to the requested speed. Extremely high values may cause the
vehicle speed to oscillate (“hunt”) while in ramp restraint.
The restraint parameter is tuned as part of the vehicle performance
adjustment process (Section 5).
M1–M4, BRAKE RATE
The braking rate deﬁnes the time it takes the controller to increase from 0%
braking output to 100% braking output (as deﬁned by the corresponding mode-
speciﬁc brake current limit) when a new direction is selected. A larger value
represents a longer time and consequently gentler braking. Faster braking is
achieved by adjusting the braking rate to a smaller value. The braking rate is
adjustable from 0.1 second to 3.0 seconds.
Note: The variable braking parameter must be programmed Off for the
braking rate parameter to apply; if variable braking is On, the braking rate will
be determined by throttle position rather than the programmed braking rate.

TAPER RATE
The taper rate affects direction-reversal at the very end of braking, just before
the vehicle stops moving in the original direction. Low taper rate values result
in faster, more abrupt direction transitions. Higher taper rate values result in
slower and smoother direction transitions. The taper rate is adjustable from 1
to 20. The taper rate is tuned as part of the vehicle performance adjustment
process (Section 5).
VARIABLE BRAKE
The variable braking parameter deﬁnes how the controller will apply braking
force when direction-reversal braking is requested. If the variable braking
parameter is programmed On, the amount of braking current applied by the
controller will be a function of the throttle’s position when braking is requested.
With variable braking, the operator can use the throttle to control the amount
of braking force applied to a moving vehicle. Increasing throttle in the direction
opposite to the vehicle’s motion will apply increasing amounts of regen braking
current to the motor, slowing the vehicle more quickly.
If a ﬁxed amount of braking force is preferred, the variable braking
parameter should be programmed Off. With variable braking Off, the control-
ler applies the full braking current speciﬁed as soon as braking is requested.

If the interlock switch opens while the vehicle is being driven, the controller uses the
motor to apply regenerative braking as soon as the programmed Sequencing Delay (see
page 42) expires. This braking—which is called interlock braking—greatly reduces
wear on the electromagnetic brake and also enables the vehicle to meet more stringent
stopping distance requirements.
As soon as interlock braking brings the motor speed to approximately zero, the
electromagnetic brake is applied. Note that for safety, the EM brake will engage after
the programmed Interlock Brake Delay (see page 28) even if interlock braking does
not bring the motor speed close to zero.
The seven Interlock Braking parameters affect the regen braking that results
when the interlock switch is opened while the vehicle is being driven.
INT BRAKE RATE
The interlock braking rate deﬁnes the time it takes the controller to increase
from 0% to 100% braking output (as determined by the max regen current
setpoints) when interlock braking is initiated. The interlock braking rate is
adjustable from 0.1 to 3.0 seconds.
MAX FWD REGEN
The maximum forward regen parameter deﬁnes the maximum regenerative
current at
maximum load while traveling in the forward direction. The max
forward regen current is adjustable from 100 amps up to the controller’s full
rated current.
If a load sensor is not used, this will be the single maximum regen current
in the forward direction.
MAX REV REGEN
The maximum reverse regen parameter deﬁnes the maximum regenerative
current at maximum load while traveling in the reverse direction. The max
reverse regen current is adjustable from 100 amps up to the controller’s full rated
current.
If a load sensor is not used, this will be the single maximum regen current
in the reverse direction.

If your application will have widely varying loads, we recommend that you include
a load sensor (at Pin 1). The use of a load sensor can prevent unnecessarily harsh
braking at light loads, which may lock up the wheels.
MIN FWD REGEN
[applicable only with optional load sensor]
The minimum forward regen parameter deﬁnes the maximum regenerative
current at minimum load while traveling in the forward direction. The Min Fwd
Regen current is adjustable from 25 amps up to the controller’s full rated
current. The forward regen current increases linearly from Min Fwd Regen to
Max Fwd Regen as the load sensor input varies from Min Load Volts to Max
Load Volts.
Note: If the load sensor’s voltage is out of range (less than 0.2 V or greater
than 4.8 V) during interlock braking while the vehicle is driving forward, the
regen current will default to the programmed Max Fwd Regen value.
MIN REV REGEN
[applicable only with optional load sensor]
The minimum reverse regen parameter deﬁnes the maximum regenerative
current at minimum load while traveling in the reverse direction. The Min Rev
Regen current is adjustable from 25 amps up to the controller’s full rated
current. The reverse regen current increases linearly from Min Rev Regen to Max
Rev Regen as the load sensor input varies from Min Load Volts to Max Load
Volts.
Note: If the load sensor’s voltage is out of range (less than 0.2 V or greater
than 4.8 V) during interlock braking while the vehicle is driving in reverse, the
regen current will default to the programmed Max Rev Regen value.
MAX LOAD VOLTS
[applicable only with optional load sensor]
The maximum load volts parameter deﬁnes the load sensor input voltage at the
maximum load. It is adjustable from 0.2 V to 4.8 V.
MIN LOAD VOLTS
[applicable only with optional load sensor]
The minimum load volts parameter deﬁnes the load sensor input voltage at the
minimum load. It is adjustable from 0.2 V up to the programmed Max Load
Volts.

The four Electromagnetic Brake parameters—along with the sequencing delay—
affect the behavior of the auxiliary driver at Pin 8. This driver is typically used for
an electromagnetic brake, as shown in the basic wiring diagram (Figure 3, page 7).
See Figure 14 for an illustration of the relationship between interlock braking, the
EM brake, and the sequencing, auxiliary, and interlock braking delays.
AUX TYPE
The auxiliary driver type parameter conﬁgures the low side driver at Pin 8. The
auxiliary driver can be programmed to operate in any of the conﬁgurations (i.e.,
Types 1 through 5) described in Table 3. Types 1 through 4 are various ways of
conﬁguring the driver for an electromagnetic brake; Type 5 is a non-EM-brake
option. If no auxiliary device will be connected to Pin 8, the auxiliary driver
should be programmed to Type 0.
EM BRAKE PWM
The auxiliary driver output (at Pin 8) can be modulated if you are using an EM
brake (or other auxiliary device) whose coil voltage rating is lower than the
battery voltage. If the electromagnetic brake PWM parameter is programmed
On, the brake will pull in at 100% PWM (full current up to 3 amps) for 500
ms and then pull back to 62.5% PWM (≈2 amps max) at a frequency of about
250 Hz and continue at this level until released. If programmed Off, the
auxiliary driver output will remain steadily at 100% PWM.
AUX DELAY
The auxiliary driver delay parameter allows a delay before the electromagnetic
brake is engaged (Pin 8 driver opened) after the vehicle reaches the neutral state
(throttle in neutral, both direction switches open, motor speed approximately
zero). The Aux Delay is adjustable from 0 to 30 seconds. When set to zero, there
is no delay and the brake is engaged as soon as the vehicle reaches the neutral
state. This parameter does not apply to Aux Type 1 (see Table 3).
For Aux Type 5, the device connected to Pin 8 will be off when the Pin
8 driver is open, and on when the driver is closed. The aux delay could be used
to allow the auxiliary device to keep running for a short while after the vehicle
reaches the neutral state.
INT BRAKE DLY
The interlock brake delay parameter allows a delay before the electromagnetic
brake is engaged after the interlock switch opens; during this time, interlock
braking is in effect. The electromagnetic brake is engaged when the delay has

the emergency reverse switch are closed. The aux driver will turn off when
the programmed Aux Delay has expired after the interlock switch opens, or
both direction switches are opened while the vehicle is driving, or the

M1–M4, MAX FWD SPD
The maximum forward speed parameter deﬁnes the maximum controller
voltage output at full throttle, in the forward direction. The maximum forward
speed parameter is adjustable from the programmed creep speed up to 100%.
It is tuned as part of the vehicle performance adjustment process (Section 5).
M1–M4, MAX REV SPD
The maximum reverse speed parameter deﬁnes the maximum controller
voltage output at full throttle, in the reverse direction. The maximum reverse
speed parameter is adjustable from 0% to 100%. It is tuned as part of the vehicle
performance adjustment process (Section 5).
CREEP SPEED
The creep speed parameter deﬁnes the initial controller output generated when
a direction is ﬁrst selected. No applied throttle is necessary for the vehicle to
enter the creep mode, only a direction signal. The controller maintains creep
speed until the throttle is rotated out of the throttle deadband (typically 10%
of throttle).
Creep speed is adjustable from 0% to 25% of the controller output; it
cannot be set higher than the lowest programmed M1–M4 maximum forward
speed. The speciﬁed creep speed is not displayed as the throttle percent in the
programmer’s Test Menu when a direction is selected and zero throttle is
applied; only the 0% throttle command is displayed.
LOAD COMP
The load compensation parameter actively adjusts the applied motor voltage
as a function of motor load current. This results in more constant vehicle speeds
over variations in driving surface (ramps, rough terrain, etc.) without the vehicle
operator constantly adjusting the throttle position; it also helps equalize loaded
and unloaded vehicle speeds. The load compensation parameter is adjustable
from 0% to 25% of the controller’s PWM output. High values will cause the
controller to be more aggressive in attempting to maintain vehicle speed.
However, too much load compensation can result in jerky vehicle starts and
speed oscillation (“hunting”) when the vehicle is unloaded.
The load compensation parameter is tuned as part of the vehicle perfor-
mance adjustment process (Section 5).

THROTTLE DB
The throttle deadband parameter deﬁnes the throttle pot wiper voltage range
that the controller interprets as neutral. Increasing the throttle deadband setting
increases the neutral range. This parameter is especially useful with throttle
assemblies that do not reliably return to a well-deﬁned neutral point, because it
allows the deadband to be deﬁned wide enough to ensure that the controller goes
into neutral when the throttle mechanism is released.
Examples of deadband settings (0%, 10%, 40%) are shown in Figure 15
for the four throttle types (see Table 4). In all the examples in Figure 15, the
throttle max parameter is set at 100%.
The throttle deadband parameter is adjustable from 0% to 40% of the
nominal throttle wiper range; the default setting is 10%. The nominal throttle
wiper voltage range depends on the throttle type selected. See Table 1 (page 9)
for the characteristics of your selected throttle type.
The throttle deadband is tuned as part of the vehicle performance adjust-
ment process (Section 5).

THROTTLE MAX
The throttle max parameter sets the wiper voltage or resistance required to
produce 100% controller output. Decreasing the throttle max setting reduces
the wiper voltage or resistance and therefore the full stroke necessary to produce
full controller output. This feature allows reduced-range throttle assemblies to
be accommodated.
The examples in Figure 16 illustrate the effect of three different throttle
max settings (100%, 90%, 60%) on the full-stroke wiper voltage or resistance
required to attain 100% controller output for the four throttle types.
The programmer displays the throttle max parameter as a percentage of
the active throttle range. The active throttle range is not affected by the throttle
deadband setting. The throttle max parameter can be adjusted from 100% to
60%; the default setting is 90%. The nominal throttle wiper range depends of
the throttle type selected. See Table 1 (page 9) for the characteristics of your
selected throttle type.
The throttle max parameter is tuned as part of the vehicle performance
adjustment process (Section 5).

Throttle Parameters
THROTTLE MAP
The throttle map parameter modiﬁes the vehicle’s response to the throttle
input. The throttle map parameter’s default setting of 50% provides a linear
output response to throttle position. Values below 50% reduce the controller
output at low throttle, providing enhanced slow speed maneuverability. Values
above 50% give the vehicle a faster, more responsive feel at low throttle.
The throttle map setting can be programmed between 20% and 80%.
The setting refers to the PWM output at half throttle, as a percentage of the
throttle’s full active range. The throttle’s active range is the voltage or resistance
between the 0% modulation point (the throttle deadband threshold) and the
100% modulation point (the throttle max threshold).
With creep speed set at 0 and maximum speed set 100%, a 50% throttle
map setting will give 50% output at half throttle. A throttle map setting of 80%
will give 80% output at half throttle. Six throttle map proﬁles (20, 30, 40, 50,
60, and 80%) are shown in Figure 17; in all these examples the creep speed is
set at 0 and the maximum speed at 100%.
Changing either of the speed parameters changes the characteristics of the
controller output relative to the throttle input and hence the throttle response.
Controller output is always a percentage of the range deﬁned by the speed
parameters (the range between the creep speed and maximum speed settings).
This means that controller output will begin to increase above the set creep
speed as soon as the throttle exceeds the neutral deadband threshold. Controller
output will continue to increase as the throttle input increases and will reach
maximum output when the throttle input reaches the throttle max threshold.
The maximum controller output at this point is deﬁned by the value of the
maximum speed parameter.

exactly as in Figure 18, except the PWM output hits a ceiling at 90%.
The throttle map is tuned as part of the vehicle performance adjustment
process (Section 5).
Increasing the creep speed value adds to the applied throttle and simply
shifts the curves up. As shown in Figure 18, a creep speed setting of 10% with
the Throttle Map set at 50% gives 60% PWM output (50% + 10%) at half
throttle.

POT LOW FAULT
The pot low fault parameter allows the controller’s pot low fault detection to
be disabled. This is useful when single-wire, ground (B-) referenced voltage
throttle inputs are used. Setting the pot low fault parameter to Off disables the
fault detection at the pot low input (Pin 7). It is recommended that the pot low
fault parameter be set to On in any application where a resistive throttle is used.
This will provide the most comprehensive throttle fault detection and provide
the safest possible vehicle operation.
Note: The programmer’s display name for the pot low fault is “Throttle
Wiper Lo.”
FIELD MIN
The minimum ﬁeld current limit parameter deﬁnes the minimum allowed
ﬁeld current, thus determining the vehicle’s maximum speed. Field Min can be
adjusted from 1.6 amps up to the lowest programmed M1–M4 Restraint value.
The Field Min parameter is tuned as part of the vehicle performance
adjustment process (Section 5).
FIELD MAX
The maximum ﬁeld current limit parameter deﬁnes the maximum allowed
ﬁeld current. The maximum ﬁeld current limit setting determines the vehicle’s
maximum torque and the maximum power that the ﬁeld winding will have to
dissipate. Field Max can be adjusted from the programmed Field Min value up
to the controller’s full rated ﬁeld current. (The full rated ﬁeld current depends
on the controller model; see speciﬁcations in Table D-1).
The Field Max parameter is tuned as part of the vehicle performance
adjustment process (Section 5).
FLD MAP START
The ﬁeld map start parameter deﬁnes the armature current at which the ﬁeld
map starts to increase from the programmed Field Min value. This parameter
is adjustable from 25 amps up to the full rated armature current value. (The full
rated armature current depends on the controller model; see speciﬁcations in
Table D-1).
The ﬁeld map start parameter is used to equalize the vehicle’s maximum
speed when loaded and unloaded. Increasing the ﬁeld map start parameter
value will increase the maximum load weight that the vehicle can carry while
maintaining maximum speed on a level surface.
The ﬁeld map start parameter is tuned as part of the vehicle performance
adjustment process (Section 5).

FIELD MAP
The ﬁeld map deﬁnes the relationship between armature current and ﬁeld
current under steady-state drive conditions. The shape of the ﬁeld map is
determined by the programmed Field Min, Field Max, Field Map, Field Map
Start, and M1-M4 Drive C/L settings.
As shown in Figure 20, the ﬁeld map parameter adjusts the ﬁeld current
at the Field Map Midpoint, which is located halfway between the programmed
Field Map Start and the programmed M1-M4 Drive C/L. With the ﬁeld map
parameter set at 50%, the motor’s ﬁeld current increases linearly with increasing
armature current—thus emulating a series wound motor.

Decreasing the ﬁeld map parameter reduces the ﬁeld current at a given
armature current. As the ﬁeld current is reduced, the motor will be able to
maintain speeds closer to the maximum speed value as its load increases;
however, the motor’s capability to produce torque at these higher speeds will
decrease. With the Field Map reduced to 20%, the field current at the Field
Map Midpoint will exceed Field Min by 20% of the range between Field Min
and Field Max.
The ﬁeld map parameter is tuned as part of the vehicle performance
adjustment process (Section 5).

FIELD CHECK
The ﬁeld check parameter determines whether the ﬁeld diagnostics will be active.
When programmed On, the controller checks for ﬁeld open and ﬁeld shorted faults.
This parameter is typically programmed On except in series motor applications,
or where the motor resistance is too high to provide valid fault data.
MAIN CONT INTR
The main contactor interlock parameter allows the OEM to deﬁne a dual
switch requirement to operate the vehicle. When this parameter is programmed
On, the controller requires that both KSI (Pin 16) and the interlock input
(Pin 15) be pulled high (to B+) before the controller will engage the main
contactor. The main contactor will open after the interlock switch is opened and
the sequencing delay expires. If this parameter is programmed Off, only the KSI
input is required for the main contactor to be engaged.
After changing the main contactor interlock setting, KSI must be cycled
for the new setting to take effect.
MAIN OPEN DLY
The main contactor open delay parameter is applicable only if the main
contactor driver interlock has been programmed On. The delay can then be set
to allow the contactor to remain engaged for a period of time after the interlock
switch is opened. The delay is useful for preventing unnecessary cycling of the
contactor and for maintaining power to auxiliary functions, such as a steering
pump motor, that may be used for a short time after the interlock switch has
opened. The main contactor open delay is programmable from 0 to 40 seconds.
After the interlock switch is opened, the programmed sequencing delay
must expire before the main contactor open delay timer starts counting.
Therefore, the time between the interlock switch opening and the main
contactor disengaging is the sum of the sequencing delay and the main contactor
open delay (see Figure 14, page 29.)
CONT DIAG
The main contactor diagnostics parameter, when programmed On, enables
two checks to verify that the main contactor is present and that it has not welded
closed. Each time the main contactor is commanded to engage, the controller
ﬁrst performs a main contactor welded test to verify that it is not already closed.
The controller then engages the contactor and performs a missing contactor test
to conﬁrm that the contactor successfully engaged.
These checks are not performed if the main contactor diagnostics param-
eter is programmed Off. The main contactor
driver, however, is always pro-
tected from overcurrents, short circuits, and overheating.

ANTI-TIEDOWN
The anti-tiedown feature prevents operators from taping or “tying down” the
mode select switches in order to operate permanently in Mode 2 or Mode 4
(which are typically the higher speed modes). Each time the interlock switch
closes, the anti-tiedown feature checks which mode is selected. If the mode select
switches are requesting Mode 2 or Mode 4 (Mode Select 1 switch closed), the
controller will default to Mode 1 or Mode 3, depending on the position of the
Mode Select 2 switch, and an anti-tiedown fault will be declared. The controller
will then remain in Mode 1 or Mode 3 until the Mode Select 1 switch is released
and reactivated. The anti-tiedown feature can be programmed On or Off.
HPD
The high pedal disable (HPD) feature prevents the vehicle from driving if
greater than 25% throttle is already applied upon startup. In addition to
providing routine smooth starts, HPD also prevents accidental sudden starts if
problems in the throttle linkage (e.g., bent parts, broken return spring) give a
throttle input signal to the controller even with the throttle released.
HPD requires the controller to receive a KSI input and an interlock input
(HPD Type 1)—or simply a KSI input (HPD Type 2)—before receiving a
throttle input greater than 25%; if the inputs are not received in the proper
sequence, the controller will inhibit output to the motor. An HPD fault can be
cleared by reducing the throttle demand to less than 25%.
HPD fault detection can be turned off by setting the HPD Type to 0. To
meet EEC requirements, HPD must be programmed to Type 1 or Type 2.
Note: The conditions for HPD faults are not affected by whether the
main contactor interlock parameter is On or Off.
HPD Type 0
:
No HPD fault detection
HPD Type 1
:
KSI+interlock
To drive the vehicle, the controller must receive both a KSI input and an interlock
input before receiving a >25% throttle input. Any other sequence will result in
an HPD fault that will prevent the vehicle from being driven.
With HPD Type 1, the sequencing delay parameter can be used to prevent
HPD faults that would otherwise occur from momentary opening of the
interlock switch while driving (see Figure 14, page 29). If the interlock switch
is opened and then quickly closed before the programmed sequencing delay
elapses, no HPD fault will be declared and operation will not be interrupted.
HPD Type 2
:
KSI only
To drive the vehicle, the controller must receive a KSI input before receiving a
throttle input greater than 25%. Violation of this sequence will result in an HPD
fault that will prevent the vehicle from being driven. With HPD Type 2, if
Sequencing Fault Parameters

42
throttle is applied after the KSI input has been received but before the interlock
switch is closed, the vehicle will accelerate to the requested speed as soon as the
interlock switch is closed.
SRO
The static return to off (SRO) feature prevents the vehicle from being started
when “in gear,” i.e., with a direction already selected. SRO checks the sequenc-
ing of the KSI and interlock inputs relative to a direction input. SRO faults can
result from using an incorrect sequence, or from using a correct sequence with
less than 50 msec between steps. If an SRO fault is declared, the controller will
inhibit output to the motor until the fault is cleared by using an acceptable
sequence.
The sequencing delay can be used to prevent SRO faults that would
otherwise occur from momentary opening of the interlock switch while driving
(see Figure 14, page 29). If the interlock switch is opened and then quickly
closed before the programmed delay time elapses, no SRO fault will be declared
and operation will not be interrupted.
Note: The conditions for SRO faults are not affected by whether the main
contactor interlock parameter is On or Off.
Three types of SRO are available, along with a “no SRO” option.
SRO Type 0
:
No SRO fault detection
SRO Type 1
:
KSI and Interlock before direction input
To drive the vehicle, the controller must receive both a KSI input and an
interlock input before receiving an input from either direction switch. The order
in which the KSI and interlock inputs are received does not matter, only that
they are both received before a direction input.
SRO Type 2
:
KSI before Interlock before direction input
To drive the vehicle, the controller must receive a KSI input and then an
interlock input before receiving an input from either direction switch.
SRO Type 3
:
KSI before Interlock before forward input
Type 3 SRO is useful for walkie vehicles that frequently operate on ramps. To drive
the vehicle in the forward direction, the controller must receive the KSI, interlock,
and forward inputs in that order, as in SRO Type 2. However, this sequence is
not required for operation in reverse. With SRO Type 3, a reverse input is
allowed at any place in the sequence: i.e., before interlock, or even before KSI.
SEQUENCING DLY
The sequencing delay feature allows the interlock switch to be cycled within a
set time—the sequencing delay—without activating HPD or SRO. This
feature is useful in applications where the interlock switch may bounce or be

43
momentarily cycled during operation. However, it is important to bear in mind
that the same sequencing delay also delays the initiation of interlock braking (see
Figure 14, page 29).
The sequencing delay can be programmed from 0.0 to 3.0 seconds, with
0.0 corresponding to no delay.
The polarity of the
S1
and
S2
connections will affect the operation of the emergency
reverse feature. The forward and reverse switches and the
S1
and
S2
connections must
be conﬁgured so that the vehicle drives away from the operator when the emergency
reverse button is pressed.
EMR REV C/L
When emergency reverse is activated, the emergency reverse current limit
parameter deﬁnes the maximum braking current during deceleration and the
maximum drive current after the vehicle switches direction. The emergency
reverse current limit is adjustable from 50 amps up to the controller’s full rated
braking current. (The full rated braking current depends on the controller
model; see speciﬁcations in Table D-1).
EMR REV CHECK
The emergency reverse check parameter is applicable only when the emergency
reverse feature is being used in the application. If emergency reverse is not being
used, this parameter should be set to Off.
When enabled (programmed On), the emergency reverse check tests for
continuity from the emergency reverse check output (Pin 10) to the emergency
reverse input (Pin 13). Therefore, the emergency reverse wiring should be
connected as closely as possible to the controller side of the emergency reverse
switch. The recommended wiring is shown in the standard wiring diagram,
Figure 3 (page 7).
EMR DIR INTR
In applications that use the emergency reverse feature, the emergency reverse
direction interlock parameter deﬁnes the requirements for resuming normal
operation after using emergency reverse. After emergency reverse has been used,
the controller sets the output drive to zero regardless of whether a direction or
throttle is being requested. With the emergency reverse direction interlock
parameter set to On, the operator can either open both direction switches or
cycle the interlock switch to enable normal operation. With the emergency
reverse direction interlock parameter set to Off, the only way for the operator
to resume normal operation is by cycling the interlock switch.

The 1243
GEN2 controller can protect the motor from damage due to overtemperature
by cutting back the motor speed. An estimate of the motor temperature is derived from
the resistance of the ﬁeld winding. The controller measures ﬁeld current, ﬁeld PWM,
and battery voltage, and uses these measurements to calculate the instantaneous ﬁeld
resistance. This value is ﬁltered and compared to two setpoints: Motor Warm
Resistance and Motor Hot Resistance. If the ﬁeld resistance reaches the Motor Warm
Resistance setpoint, the motor maximum speed will be limited to the programmed
Warm Speed. If the ﬁeld resistance reaches the Motor Hot Resistance setpoint, the
controller will no longer drive but all braking functions will remain active. If this
motor protection feature is not desired, it can be disabled by programming the motor
resistance compensation parameter Off.
WARM SPEED
The warm speed parameter deﬁnes the maximum drive speed output when the
motor ﬁeld resistance is at or above the Motor Warm Resistance setpoint. The
warm speed is adjustable from 0 to 100% of drive output.
MOT WRM x10 mΩ
The motor warm resistance parameter deﬁnes the ﬁeld resistance setpoint at
which a motor warm fault will occur and the maximum speed will be controlled
by the Warm Speed setting.
Note: The parameter value is in ten-milliohm units. If you want to program
the Motor Warm Resistance setpoint to 900 mΩ (0.9 Ω), you would enter 90
for the MOT WRM x10 mΩ value. The Motor Warm Resistance setpoint is adjust-
able from 100 mΩ (MOT WRM x10 mΩ =10) up to the Motor Hot Resistance
setpoint.
MOT HOT x10 mΩ
The motor hot resistance parameter deﬁnes the ﬁeld resistance setpoint at
which a motor hot fault will occur and no drive output will be allowed. It is
adjustable from the Motor Warm Resistance setpoint up to 2500 mΩ (2.5 Ω).
The value entered is in ten-milliohm units, which means the maximum Motor
Hot Resistance value is one-tenth of 2500 (i.e., MOT HOT x10 m
Ω =250).
MOT Ω COMP
The motor resistance compensation parameter is used (programmed On) to
enable the motor overtemperature protection feature.

Hourmeters
Two individual hourmeters are built into the 1243GEN2 controller, each with non-
volatile memory:
• a total hourmeter, that measures the total operating time (KSI on-time), and
• a traction hourmeter, that measures the time that a direction is selected.
Each hourmeter has a corresponding service timer and disable timer. Hourmeter
information is viewable via the programmer or the Spyglass display.
For each hourmeter, the service timer is used to set the time before scheduled
maintenance is due. When the set service time expires, the service warning fault
occurs and the disable timer starts. If the programmed disable time expires before the
scheduled maintenance is performed, the controller defaults to the programmed
traction fault speed.
The 1243GEN2 controller is shipped from the factory with each of its two hourmeters
preset to 0. If the controller is being installed in a new vehicle, these presets do not
need to be adjusted. If the controller is being installed in a “used” vehicle, however,
it may be desirable to transfer the existing hourmeter values to the new controller. To
do this, the existing hourmeter values must be entered as follows.
Each meter records time to 999999.9 hours (114 years), and will roll over to
000000.0 if this is exceeded. The adjust high, adjust middle, and adjust low
parameters each set two of the digits on the meter: HHMMLL.
ADJ HOURS HIGH
The adjust hours high parameter is used to set the highest two digits, from 00
to 99.
ADJ HOURS MID
The adjust hours middle parameter is used to adjust the middle two digits,
from 00 to 99.
ADJ HOURS LOW
The adjust hours low parameter is used to adjust the lowest two digits, from
00 to 99. It is not possible to set tenths.
SET TOTL HRS
The set total hours parameter is used to apply the preset high, middle, and low
values to the total (i.e., KSI on-time) hourmeter. First, adjust the preset values
as desired for the total hourmeter. Then, program the Set Total Hours parameter
On, which automatically loads the preset values.

should be programmed Off.
SET TRAC HRS
The set traction hours parameter is used to apply preset high, middle, and low
values to the traction hourmeter. First, adjust the preset values as desired for the
traction hourmeter. Then, program the Set Traction Hours parameter On,
which automatically loads the preset values. Once they have been loaded, the Set
Traction Hours parameter should be programmed Off.
SRVC TOTL HRS
The total service hours parameter is used to set the timer for the next scheduled
overall maintenance. The service interval can be up to 5,000 hours. The total
service timer is adjustable between 0.0 and 50.0, in 0.5 increments, with 25.0
being equivalent to 2,500 hours (25.0 × 100).
Setting the parameter to 0 means that the timer will never expire—i.e.,
there will be no overall maintenance reminder.
SRVC TRAC HRS
The traction service hours parameter is used to set the timer for the next
scheduled traction motor maintenance. The service interval can be up to 5,000
hours. The traction service timer is adjustable between 0.0 and 50.0, in 0.5
increments, with 25.0 being equivalent to 2,500 hours (25.0 × 100).
Setting the parameter to 0 means that the timer will never expire—i.e.,
there will be no motor maintenance reminder.
DIS TOTL HRS
The total disable hours parameter is used to set the total disable timer; it can
be adjusted between 0 and 250 hours, in 1 hour increments. If the total disable
timer expires, the traction fault speed goes into effect.
Setting the parameter to 0 means that the total disable timer will never
expire and therefore never invoke the traction fault speed.
DIS TRAC HRS
The traction disable hours parameter is used to set the traction disable timer;
it can be adjusted between 0 and 250 hours, in 1 hour increments. If the traction
disable timer expires, the traction fault speed goes into effect.

Setting the parameter to 0 means that the traction disable timer will never

TRAC FAULT SPD
The traction fault speed parameter sets the maximum drive speed in the event
the traction disable timer expires or the total disable timer expires; it can be
adjusted between 0–100% of drive output, and applies to all modes.
The hourmeter service timers must be reset (programmed Off) after service is
performed, using the Service Total and Service Traction parameters.
Occasionally, the vehicle may be brought in for servicing before its scheduled
maintenance is due—for example, because of some specific problem. You might want
to check the service timers at this time to see how many hours they have accumulated.
If routine maintenances is due shortly, you could perform it now instead, and reset
the appropriate service timer—thus avoiding an extra trip to the shop.
SERVICE TOTL
When the total service timer expires, the controller automatically sets the
service total parameter On. The Service Total parameter must then be pro-
grammed Off to indicate the appropriate service has been performed.
If a vehicle is brought in for service before a service warning is issued, you
can check the accumulated total service hours. Plug in the 1311 programmer
and go to the Monitor menu. Multiply the “Tot Srvc X25” value by 25 and add
the “+Tot Srvc” value; this is how many total hours have elapsed since the total
service timer was last reset.
When service is performed before the total service timer expires, the
Service Total parameter must be programmed On and then Off to reset it.
SERVICE TRAC
When the traction service timer expires, the controller automatically sets the
service traction parameter On. The Service Traction parameter must then be
programmed Off to indicate the appropriate service has been performed.
If a vehicle is brought in for service before a service warning is issued, you
can check the accumulated traction service hours. Plug in the 1311 program-
mer and go to the Monitor menu. Multiply the “Trac Srvc X25” value by 25
and add the “+Trac Srvc” value; this is how many traction hours have elapsed
since the traction service timer was last reset.
When service is performed before the traction service timer expires, the
Service Traction parameter must be programmed On and then Off to reset it.

The Spyglass gauge displays hourmeter data for 5 seconds each time the

PUMP METER
The pump meter parameter, when programmed On, conﬁgures the Fault
Output 1 line (at Pin 2) to function as an input to measure the hours a pump
is running. The pump is considered to be running when Pin 2 is at the battery
voltage. When the pump meter parameter is programmed On, the traction
hourmeter serves as a combination traction/pump hourmeter, and all the above
“TRAC” hourmeter parameters apply to both traction hours and pump hours.
The traction/pump hourmeter counts the hours when a direction is selected and
the hours when the pump is running.

BDI
The battery discharge indicator constantly calculates the battery state-of-charge
whenever KSI is on. When KSI is turned off, the present battery state-of-charge is
stored in non-volatile memory. BDI information is viewable via the Spyglass display
and via the 1311 programmer’s Monitor Menu as BDI%. Three parameters are used
to adjust the display.
The standard values for flooded lead acid and sealed maintenance-free batteries
are listed below.
BATTERY TYPE
FLOODED SEALED
Full volts (VPC) 2.04 2.04
Empty volts (VPC) 1.74 1.91
Reset volts (VPC) 2.10 2.10
Custom values can be entered based on speciﬁc batteries in consultation with a Curtis
applications engineer.
Note: BDI values are set without the decimal point; 2.04 volts per cell, for
example, will appear as 204 (i.e., VPC × 100) on the programmer. The Full,
Empty, and Reset voltages are set in VPC units. For whole-battery voltages (rather
than VPC values), see Table 5.
FULL VOLTS
The full voltage parameter sets the battery voltage that will be considered 100%
state-of-charge. When a loaded battery drops below this voltage, it begins to lose
charge. The full voltage value can be set from the programmed Empty Volts
value up to the programmed Reset Volts value, in 0.01 VPC increments.
After adjusting Full Volts, KSI must be cycled for the new setting to take
effect.
EMPTY VOLTS
The empty voltage parameter sets the battery voltage that will be considered 0%
state-of-charge. When the battery remains under this voltage consistently, the
BDI will read 0% state of charge. The empty voltage value can be set from 1.50
up to the programmed Full Volts value, in 0.01 VPC increments.
After adjusting Empty Volts, KSI must be cycled for the new setting to
take effect.
RESET VOLTS
The reset voltage parameter sets the battery voltage used to detect the 100%
state-of-charge point on a battery with no load. Whenever the programmed
Reset Voltage is present for 2 seconds (except during regenerative braking), the

BATTERY ADJUST
The battery adjustment parameter is used to adjust the BDI algorithm to
compensate for battery capacity. Higher capacity batteries can spend more time
below the Full Volts setting before beginning to lose charge. The battery
adjustment parameter sets the number of seconds of droop required before the
battery state of charge is decremented by 1%. It is adjustable from 0.1 to 20.0
seconds.
BDI DISABLE
The BDI disable parameter, when programmed On, limits the vehicle’s maxi-
mum speed to the BDI Limit Speed when the battery state-of-charge is 0%.
BDI LIMIT SPEED
The BDI limit speed parameter sets the vehicle’s maximum allowed speed when
the BDI disable parameter is programmed On and the battery state of charge is
0%. The BDI limit speed is adjustable from 0 to 100% of drive output.
If the BDI disable parameter is programmed Off, the BDI limit speed will
not be in effect.

FAULT CODE
The 1243GEN2 controller has two fault outputs, at Pins 2 and 3, which can be
used to transmit signals to LEDs located on the display panel or on any remote
panel. The fault outputs can be conﬁgured to display faults in two different
formats: Fault Code format or Fault Category format. The fault code parameter
is used to select the preferred format.
In Fault Code format (fault code parameter On), the two fault outputs
operate independently. When a fault is present, the Fault 1 driver (Pin 2)
provides a pulsed signal equivalent to the fault code flashed by the controller’s
built-in Status LED; the fault codes are listed in Table 8, page 74. The Fault 2
driver (Pin 3) will steadily pull low (to B-) when any fault is present, and can be
used to drive a fault/no-fault LED. When no faults are present, the Fault 1 and
Fault 2 outputs will both be high.
In Fault Category format (fault code parameter Off), each combination
of the two fault outputs deﬁnes one of four fault categories. Table 6 lists the
possible faults included in each category.
Note: Alternatively, Pin 2 can be used as a pump meter input, and Pin 3
can be used to interface an external auxiliary enable circuit; see fault output
wiring, page 14.

BDI LOCKOUT
When the BDI lockoutiparameter is programmed On, the Fault 2 output (at
Pin 3) can be used as an interface to an external auxiliary enable circuit. When
BDI%=0, the Fault 2 output will be high; when BDI%≥1, the Fault 2 output
will be low.
When BDI lockout is programmed Off, the Fault 2 output is determined
by the setting of the Fault Code parameter.

troubleshooting section (Section 7) for further information.
The installation checkout can be conducted with or without a program-
mer. The checkout procedure is easier with a programmer. Otherwise, observe
the Status LED (located in the controller’s label area) for diagnostic codes. The
codes are listed in Section 7.
Put the vehicle up on blocks to get the drive wheels up
off the ground before beginning these tests.
Do not stand, or allow anyone else to stand, directly in
front of or behind the vehicle during the checkout.
Make sure the keyswitch is off, the throttle is in neutral,
and the forward and reverse switches are open.
Wear safety glasses and use well-insulated tools.
1. If a programmer is available, connect it to the programmer connector.
2. Turn the keyswitch on. The programmer should power up with an initial
display, and the controller’s Status LED should begin steadily blinking
a single flash. If neither happens, check for continuity in the keyswitch
circuit and controller ground.
3. Select the System Faults menu. The display should indicate “No Known
Faults.” Close the interlock switch. To do this on a walkie, pull the tiller
down to the operating position. The Status LED should continue
blinking a single flash and the programmer should continue to indicate
no faults.
If there is a problem, the LED will ﬂash a diagnostic code and the
programmer will display a diagnostic message. If you are conducting
the checkout without a programmer, look up the LED diagnostic code
in Section 7: Diagnostics and Troubleshooting.
When the problem has been corrected, it may be necessary to cycle
the keyswitch in order to clear the fault.
4. With the interlock switch closed, select a direction and operate the
throttle. The motor should begin to turn in the selected direction. If it
does not, ﬁrst verify the wiring to the forward and reverse switches. If the

switch wiring is correct, turn off the controller, disconnect the battery,
and exchange the motor’s ﬁeld connections (S1 and S2) on the control-
ler. The motor should now turn in the proper direction.
The motor should run proportionally faster with increasing throttle.
If not, refer to Section 7.
CAUTION:
The polarity of the S1 and S2
connections will affect the operation of the emergency reverse feature.
The forward and reverse switches and the S1 and S2 connections must
be conﬁgured so that the vehicle drives away from the operator when the
emergency reverse button is pressed.
5. Select the Monitor menu, and scroll down to observe the status of the
forward, reverse, interlock, emergency reverse, and mode switches. Cycle
each switch in turn, observing the programmer. The programmer should
display the correct status for each switch.
6. Verify that all options, such as high pedal disable (HPD), static return
to off (SRO), and anti-tiedown are as desired.
7. On walkies, verify that the emergency reverse feature is working correctly
(i.e., press the emergency reverse button, and conﬁrm that the wheels
turn in the proper direction to drive the vehicle away from the operator).
If you have the optional emergency reverse check wiring, verify the
checking circuit. Apply throttle so that the drive wheel spins. While
continuing to apply throttle, temporarily disconnect one of the emer-
gency reverse wires. The drive wheel should come to a stop and a fault
should be indicated. Be sure to reconnect the emergency reverse wire
after completing this test of the checking circuit.

5 — VEHICLE PERFORMANCE ADJUSTMENT
VEHICLE PERFORMANCE ADJUSTMENT
The 1243GEN2 controller is a very powerful vehicle control system. Its wide
variety of adjustable parameters allow many aspects of vehicle performance to
be optimized. This section provides explanations of what the major tuning
parameters do and instructions on how to use these parameters to optimize the
performance of your vehicle. Once a vehicle/motor/controller combination has
been tuned, the parameter values can be made standard for that system or vehicle
model. Any changes in the motor, the vehicle drive system, or the controller will
require that the system be tuned again to provide optimum performance.
The tuning procedures should be conducted in the sequence given,
because successive steps build upon the ones before. The tuning procedures
instruct personnel how to adjust various programmable parameters to accom-
plish speciﬁc performance goals. It is important that the effect of these pro-
grammable parameters be understood in order to take full advantage of the
controller’s features. Please refer to the descriptions of the applicable parameters
in Section 3 if there is any question about what any of them do.
The 1243GEN2’s MultiMode™ feature allows the vehicle to be conﬁgured
to provide four distinct operating modes. Typically Mode 1 is conﬁgured for
slow precise indoor maneuvering, Mode 4 for faster, long distance, outdoor
travel, and Modes 2 and 3 for application-speciﬁc special conditions. Some of
the tuning procedures may need to be repeated four times, once for each mode.
MAJOR TUNING
Four major performance characteristics are usually tuned on a new vehicle:
1
Tuning the Throttle’s Active Range
2
Tuning the Controller to the Motor
3 Setting the Vehicle’s Unloaded Top Speed
4
Equalization of Loaded/Unloaded Vehicle Speed.
These four characteristics should be tuned in the order listed.
1
Tuning the Throttle’s Active Range
Before attempting to optimize any speciﬁc vehicle performance characteristics,
it is important to ensure that the controller output is operating over its full range.
The procedures that follow will establish Throttle Deadband and Throttle Max
parameter values that correspond to the absolute full range of your particular
throttle mechanism. It is advisable to allow some buffer around the absolute full
range of the throttle mechanism to allow for throttle resistance variations over
time and temperature as well as variations in the tolerance of potentiometer
values between individual throttle mechanisms.

-A Tuning the Throttle Deadband
STEP 1. Jack the vehicle wheels up off the ground so that they spin freely.
STEP 2. Plug the programmer into the controller and turn on the key-
switch and interlock switch (if used).
STEP 3. Select the Monitor Menu. The Throttle % ﬁeld should be visible
at the top of the display. You will need to reference the value
displayed here. For convenience, set a bookmark here so you can
return easily to read the Throttle % value.
STEP 4. Scroll down until the Forward Input ﬁeld is visible. The display
should indicate that the forward switch is Off.
STEP 5. Slowly rotate the throttle forward until the display indicates that
the forward switch is On. Use care with this step as it is important
to identify the threshold throttle position at which the forward
switch is engaged and the controller recognizes the forward
command.
STEP 6. Without moving the throttle, return to the Throttle % ﬁeld and
read the value shown. This value should be zero. If the Throttle
% value is zero, proceed to Step 7. If it is greater than zero, the
Throttle Deadband parameter must be increased (go to the
Program menu) and the procedure repeated from Step 5 until the
Throttle % is zero at the forward direction engagement point.
Setting a second bookmark at the Throttle Deadband parameter
will allow you to toggle back and forth easily between the
parameter and the Throttle % ﬁeld.
STEP 7. While observing the Throttle % value in the programmer’s Test/
Monitor Menu, continue to rotate the throttle past the forward
switch engagement point. Note where the Throttle % value
begins to increase, indicating that the controller has begun to
supply drive power to the motor. If the throttle had to be rotated
further than desired before the Throttle % value began to in-
crease, the Throttle Deadband parameter value must be
decreased
and the procedure repeated from Step 5. If the amount of rotation
between the point at which the forward switch is engaged and the
Throttle % value begins to increase is acceptable, the Throttle
Deadband is properly tuned.
STEP 8. If a bidirectional (wigwag) throttle assembly is being used, the
procedure should be repeated for the reverse direction. The
Throttle Deadband value should be selected such that the throttle
operates correctly in both forward and reverse.

-B Tuning the Throttle Max
STEP 1. Jack the vehicle wheels up off the ground so that they spin freely.
STEP 2. Plug the programmer into the controller and turn on the key-
switch and interlock switch (if used).
STEP 3. Select the Monitor Menu. The Throttle % ﬁeld should be visible
at the top of the display. You will need to reference the value
displayed here. For convenience, set a bookmark here so you can
return easily to read the Throttle % value.
STEP 4. Rotate the throttle forward to its maximum speed position and
observe the Throttle % value. This value should be 100%. If it is
less than 100%, the Throttle Max parameter value must be
decreased to attain full controller output at the maximum throttle
position. Use the programmer to decrease the Throttle Max
parameter value, and repeat this step until the value is 100%.
Setting a second bookmark at the Throttle Max parameter will
allow you to toggle back and forth easily between the parameter
and the Throttle % ﬁeld.
STEP 5. Now that the full throttle position results in a 100% value for
Throttle %, slowly reduce throttle until the Throttle % value
drops below 100% and note the throttle position. This represents
the extra range of motion allowed by the throttle mechanism. If
this range is large, you may wish to decrease it by increasing the
Throttle Max parameter value. This will provide a larger active
throttle range and more vehicle control. Using the programmer,
increase the Throttle Max parameter value and repeat the test
until an appropriate amount of extra range is attained.
STEP 6. If a wigwag throttle is being used, repeat the procedure for the
reverse direction. The Throttle Max value should be selected such
that the throttle operates correctly in both forward and reverse.

2
Tuning the Controller to the Motor
The 1243GEN2 controller has the flexibility to be tuned to nearly any separately
excited motor from any manufacturer. The programmable parameters allow full
control of the motor’s maximum armature current during driving and braking
and full control of the motor’s maximum and minimum ﬁeld current as well as
the ﬁeld current relationship to the armature current. This flexibility allows
motor performance to be maximized while protecting it from operating outside
its safe commutation region.
In order to properly tune the controller, the following information should
be obtained from the motor manufacturer:
• MAXIMUM ARMATURE CURRENT RATING
• MAXIMUM FIELD CURRENT RATING
• MINIMUM FIELD CURRENT RATING
• FIELD RESISTANCE, HOT AND COLD.
The performance of a separately excited motor changes depending on tempera-
ture. This is due to the change in ﬁeld winding resistance as the motor heats up
through use. When the ﬁeld winding temperature increases, so does its resis-
tance; therefore, the maximum current that can be forced through the winding
is reduced. Reductions in the ﬁeld current over the motor’s typical operating
temperature range can be 10% to 50%. Since the maximum available ﬁeld
current determines the maximum torque that can be produced by the motor, the
vehicle’s performance under load and up inclines will change as the motor heats
up. The change in performance can be limited by tuning the motor when it is
hot rather than cold. Therefore, it is recommended that the following procedure
be performed with a hot motor.
STEP 1. Using the programmer’s Program Menu, set the Drive Current
Limit parameter value in each mode to the smaller of: (a) the
motor’s peak armature current rating, or (b) the maximum
controller drive current limit. This value can later be adjusted to
establish the desired vehicle driving feel in each mode.
STEP 2. Set the Braking Current Limit parameter value in each mode to
the smaller of: (a) the maximum motor armature current rating,
or (b) the maximum controller braking current limit. This value
can later be adjusted to establish the desired vehicle braking feel
in each mode.
STEP 3. To set the Field Max parameter value, ﬁrst decide whether you
want to maintain consistent vehicle operation throughout the
motor’s temperature range. If you do, proceed to Step 4. If,
however, maintaining operational consistency across motor tem-
perature is not a concern, but achieving maximum torque is,
proceed to Step 5.
STEP 4. For the most consistent operation across temperature, set the
Field Max parameter to the maximum ﬁeld current available at
Curtis 1243GEN2 Manual
59
5 — VEHICLE PERFORMANCE ADJUSTMENT
low battery voltage and with a hot motor. To determine this
value, divide the low battery voltage (typically 70% of nominal)
by the high temperature ﬁeld winding resistance speciﬁcation
provided by the manufacturer. Set the Field Max parameter to
this value. This will provide good consistency between motor
performance in both hot and cold states.
STEP 5. For the maximum torque regardless of temperature, set the Field
Max parameter to the motor’s rated absolute maximum ﬁeld
current. To determine the absolute maximum ﬁeld current,
divide the nominal battery voltage by the low temperature ﬁeld
winding resistance speciﬁcation provided by the manufacturer.
Set the Field Max parameter to this value. This will provide the
maximum possible torque under all conditions.
This has now set the Max Field parameter. The next step is to set the Min Field
parameter. NOTE: The Field Min parameter should never be set below the
rated value speciﬁed by the manufacturer. Operating the motor at lower ﬁeld
currents than speciﬁed will result in operation outside the motor’s safe commu-
tation region and will cause arcing between the brushes and commutator,
signiﬁcantly reducing motor and brush life. The Field Min parameter value can
be increased from the manufacturer’s speciﬁed value to limit the vehicle’s top
speed. (Setting the vehicle top speed will be addressed in tuning procedure
3
.)
If the controller is tuned such that the system is operating outside the
motor’s safe commutation region, there will be audible and visual indications.
Under normal operation, the motor will emit a whine with a pitch that
increases with increasing rotation speed. If a “scratchy” sound is also heard, this
is usually an indication that pin arcing is occurring in the motor and it is
operating outside its safe commutation region. This operation is normally
accompanied by a strong smell from the motor. If the brushes and commutator
bars are visible, arcing may be visible. The further outside the safe commutation
region the motor is operating, the worse the arcing will be. Operation outside
the safe commutation region is very detrimental to the motor. The Field
Min and possibly also the Field Map parameter should be increased until the
indications of arcing stop. Decreasing the Field Map Start parameter will also
help to move operation back into the safe commutation region.

5 — VEHICLE PERFORMANCE ADJUSTMENT
3
Setting the Vehicle’s Unloaded Top Speed
The controller and vehicle should be conﬁgured as follows prior to setting the
maximum unloaded vehicle speed:
• Max Speed = 100%, all modes
• Drive Current Limit as established in tuning procedure
2
• Field Map = 50%
• Field Map Start = 50% of the speciﬁed drive current limit
• Field Min = manufacturer’s speciﬁed minimum (if available);
otherwise, 3 amps
• Load Comp = 0
• The vehicle should be unloaded
• The vehicle battery should be fully charged.
The vehicle should be driven on a flat surface in a clear area during this
procedure. Since the vehicle may initially be traveling at speeds in excess of the
ﬁnal intended speed, precautions should be taken to ensure safety of test
personnel and anyone in the test area.
STEP 1. Select the programmer’s Program Menu and scroll down until the
Field Min parameter is at the top of the display.
STEP 2. Power up the vehicle and apply full throttle. While driving the
vehicle with full throttle applied, adjust the Field Min parameter
value to set the desired top speed. Increasing the Field Min value
decreases the vehicle’s top speed; decreasing the Field Min value
increases the vehicle’s top speed.
CAUTION:
Do not decrease the
Field Min parameter value below the motor manufacturer’s
recommended minimum ﬁeld current value, and do not increase
it above 10 amps.
STEP 3. If the Field Min parameter value is increased to 10 amps and the
vehicle’s top speed has still not been sufﬁciently reduced, the Max
Speed parameter should be used to bring the vehicle top speed
down to the desired level. First, decrease the Field Min parameter
value, setting it to optimize smooth starting. Then adjust the
Max Speed parameter per Step 4 to bring the vehicle top speed
down to the desired level.
NOTE: If the Field Min parameter is set
too high, the high initial torque created by the high ﬁeld current
may cause overly abrupt starts; this is why we recommend using
the Max Speed parameter in those cases where a moderate Field
Min setting does not sufﬁciently reduce the vehicle top speed.
STEP 4. Scroll up the Program Menu until the Max Speed parameter is at
the top of the display. While driving the vehicle with the Field
Min set at the value selected in Step 3, decrease the Max Speed
parameter value until the desired vehicle top speed is set.
Curtis 1243GEN2 Manual
61
5 — VEHICLE PERFORMANCE ADJUSTMENT
STEP 5. For Walkie/Rider Applications: Typically, different top speeds are
desired for walkie and rider operation. To tune a walkie/rider
vehicle’s top speed, ﬁrst tune it for rider operation by using the
Field Min parameter. Then, to set the top speed for walkie
operation, leave the Field Min parameter alone and decrease the
Max Speed parameter until the desired walking vehicle speed is
reached.
4
Equalization of Loaded and Unloaded Vehicle Speed
The top speed of a loaded vehicle can be set to approach the unloaded top speed
by tuning the Field Map Start and Load Compensation parameters. It is
recommended that you review the description of the Field Map Start and Load
Compensation parameters in Section 3 before starting this procedure.
STEP 1. The vehicle’s unloaded top speed should already have been set. If
it was not, it should be set before the vehicle’s loaded top speed
is established.
STEP 2. Once the vehicle’s unloaded top speed has been set, load the
vehicle to its desired load capacity. Leave the Field Min and Speed
Max parameters at the settings determined during the unloaded
test.
STEP 3A. If the intent is to minimize the difference between the loaded and
unloaded vehicle speeds, then:
(i) Drive the fully loaded vehicle on flat ground with full throttle
applied. When the vehicle reaches maximum speed, observe the
armature current displayed in the programmer’s Monitor Menu.
(ii) Set the Field Map Start parameter slightly higher than the
observed armature current value.
(iii) Test the loaded/unloaded speed variation. If the observed
variation is unacceptable, proceed to “(iv).”
(iv) Increase the Load Compensation parameter and retest the
speed regulation. The Load Comp parameter can be increased
until the desired regulation is achieved or the vehicle begins to
oscillate (“hunt”) at low throttle. If the loaded/unloaded speed
variation is acceptable but the average speed is not, adjustments
can be made to the Field Min parameter.
STEP 3B. If the intent is to make the loaded speed less than the unloaded
speed (for reasons of safety, efﬁciency, or reduced motor heating),
then:
(i) Unload the vehicle and drive it on flat ground with full throttle
applied. When the vehicle reaches maximum speed, observe the
armature current displayed in the Monitor Menu.
Curtis 1243GEN2 Manual
62
5 — VEHICLE PERFORMANCE ADJUSTMENT
(ii) Set the Field Map Start parameter slightly higher than the
observed armature current value.
(iii) Load the vehicle and drive it on flat ground with full throttle
applied. Further adjustments to the vehicle’s loaded speed can
now be made by varying the Field Map parameter. Increasing the
Field Map value will decrease the vehicle’s loaded speed, and
decreasing the Field Map value will increase the vehicle’s loaded
speed.
CAUTION:
If the Field Map Start parameter is set too high, the motor’s
safe commutation region may be exceeded. If this is the case, reduce the
Field Map Start parameter to a safe value. Then, adjust the Field Map
parameter as needed to reach the desired loaded top speed. Reducing the
Field Map value will help bring the loaded speed closer to the unloaded
speed. However, care must still be taken because it is possible for too low
Field Map values—like too high Field Map Start values—to result in
exceeding the motor’s safe commutation region.
FINE TUNING
Four additional vehicle performance characteristics can be adjusted:
5
Response to Reduced Throttle
6
Response to Increased Throttle
7 Smoothness of Direction Transitions
8 Ramp Climbing.
These characteristics are related to the “feel” of the vehicle and will be different
for various applications. The ﬁne tuning adjustments are especially noticeable
in precision maneuvering, which is typically Mode 1. Careful tuning of the M1
Accel Rate, M1 Decel Rate, M1 Restraint, M1 Braking Rate, and M1 Braking
Current Limit parameters will ensure the most comfortable possible vehicle
response at low speeds.
5
Response to Reduced Throttle
The way the vehicle behaves when the throttle is reduced or completely released
can be adjusted to suit your application, using the Decel Rate and Restraint
parameters. Refer to the description of these parameters in Section 3 before
beginning this procedure.
STEP 1. Set the Decel Rate based on the desired time for the vehicle to
stop upon release of throttle when traveling at full speed with full
load. If the vehicle brakes too abruptly when the throttle is
released, increase the Decel Rate.
Curtis 1243GEN2 Manual
63
5 — VEHICLE PERFORMANCE ADJUSTMENT
STEP 2. The default Restraint setting (5 amps) should work well for most
vehicles. If the vehicle exhibits excessive overspeed when driving
down a ramp, increase the Restraint value. If the vehicle “speed
hunts” while driving down a ramp or brakes too abruptly at low
or released throttle, decrease the Restraint value.
STEP 3. If the Restraint value has been adjusted, retest braking behavior
when throttle is reduced to ensure that it still has the desired feel.
If it does not, the Decel Rate should be re-adjusted as in Step 1.
6
Response to Increased Throttle
The way the vehicle reacts to quick or slow increased throttle requests can be
modiﬁed using the Accel Rate, Current Ratio, Quick Start, and Throttle Map
parameters. Optimal vehicle response is tuned by adjusting these parameters
and then accelerating the vehicle from a dead stop under various throttle
transition conditions.
STEP 1. Set Quick Start = 0 and Throttle Map = 50%.
STEP 2. Drive the vehicle and adjust the Accel Rate for the best overall
response. If the vehicle starts too slowly under all driving con-
ditions, the Accel Rate should be reduced.
STEP 3. Increasing vehicle acceleration. If acceleration feels good for slow
or moderate throttle transitions but the vehicle initially starts too
slowly, set the Current Ratio parameter to 2 or higher. If the
vehicle does not accelerate as quickly as desired when the throttle
is transitioned quickly from zero to full speed, increase the Quick
Start parameter value to obtain the desired fast throttle response.
STEP 4. Achieving better control at low speeds. If the vehicle responds
well for fast, full range throttle transitions but is too jumpy
during low speed maneuvering, reduce the Throttle Map and/or
set the Current Ratio to 1. If these adjustments are insufﬁcient,
decrease the Quick Start parameter value to obtain the desired
precision maneuvering.
7
Smoothness of Direction Transitions
Additional ﬁne tuning can be performed to enhance the vehicle’s transitions
between braking and driving, after the major performance and responsiveness
tuning—
1
through
6
above—has been completed.
STEP 1. Ensure that the Braking Current Limit and Braking Rate param-
eters have been set for the desired response (see Section 3, pages 23
and 24).
Curtis 1243GEN2 Manual
64
5 — VEHICLE PERFORMANCE ADJUSTMENT
STEP 2. If the transition is too abrupt: increase the Taper Rate and/or set
the Variable Braking parameter to On. Secondary adjustments
can be made by increasing the Accel Rate.
STEP 3. If the transition is too slow: decrease the Taper Rate and set
Creep Speed to 5% or greater. Secondary adjustments can be
made by decreasing the Accel Rate, increasing the Current Ratio,
or increasing the Quick Start parameter value.
8
Ramp Climbing
The vehicle response to increased gradients such as loading ramps can be tuned
via the Field Map parameter. Decreasing the Field Map parameter allows faster
vehicle speeds while climbing ramps, but it also has the effect of reducing the
ability of the controller to generate torque in the vehicle’s mid range speeds.
STEP 1. If faster vehicle speed is desired when climbing ramps, decrease
the Field Map parameter value until the desired ramp climbing
speed is attained. It should be noted that if the motor’s torque
capability is exceeded under the conditions of load weight and
ramp gradient, vehicle speed will be limited by the motor’s
capability and the desired vehicle speed may not be attainable.
The system will ﬁnd a compromise point at which sufﬁcient
motor torque is generated to climb the ramp at an acceptable
speed. If the Field Map parameter value is reduced to 0% and the
desired speed is still not attained, the system is being limited by
the motor’s torque capability under these operating conditions.
CAUTION:
be careful when reducing the Field Map parameter
since at low Field Map values it is possible that the motor could
be operated outside its safe commutation region.
STEP 2. If the drive system cannot produce sufﬁcient torque for a fully
loaded vehicle to climb the desired ramp, try increasing the Field
Map, Field Max, and/or Drive Current Limit parameters. The
impact of increasing these parameter values on other driving
characteristics must be evaluated. Increasing the Field Max will
provide more ﬁeld current, and increasing the Drive Current
Limit will provide more armature current. If the Field Max is set
at the manufacturer’s speciﬁed limit and the Drive Current Limit
is set at the rated maximum, then vehicle speed up the ramp is
limited by the motor or the vehicle’s gearing and cannot be
increased by tuning the controller.
NOTE: To determine if the
controller’s armature current is at its set value during ramp
climbing, read the “Arm Current” in the programmer’s Monitor
Menu.

DIAGNOSTICS AND TROUBLESHOOTING
The 1243GEN2 controller provides diagnostics information to assist technicians
in troubleshooting drive system problems. The diagnostics information can be
obtained by observing the appropriate display on the handheld programmer, the
fault message displayed on the Spyglass gauge, the fault codes issued by the
Status LED, or the fault display driven by the controller’s fault outputs (Fault 1
and Fault 2). Refer to the troubleshooting chart (Table 7) for suggestions
covering a wide range of possible faults.
PROGRAMMER DIAGNOSTICS
The handheld programmer presents complete diagnostic information in plain
language. Faults are displayed in the System Faults Menu, and the status of the
controller inputs/outputs is displayed in the Monitor Menu.
Accessing the programmer’s Fault History Menu provides a list of the
faults that have occurred since the fault history ﬁle was last cleared. Checking
(and clearing) the fault history ﬁle is recommended each time the vehicle is
brought in for maintenance.
For information on 1311 programmer operation, see Appendix B. If you
are using the older 1307 programmer, refer to existing documentation.
SPYGLASS DIAGNOSTICS
The eight-character LCD on the Spyglass displays a continuous sequence of
hourmeter, battery state-of-charge, and fault messages.
Fault messages are displayed using the same codes that are flashed by the
LED (see Table 8). For example, the LED flashes 3,2 for a welded main
contactor:
¤¤¤ ¤¤ ¤¤¤ ¤¤ ¤¤¤ ¤¤
( 3 , 2 ) ( 3 , 2 ) ( 3 , 2 )
and the corresponding Spyglass message is:
CODE 32
When a fault message is being displayed, the red Fault LED (labeled with
a wrench symbol) flashes to catch the operator’s attention.
The LCD also displays a warning when either service timer expires. The
service warning is not considered a fault and the red Fault LED does not flash.
The word SERVICE is displayed for about 20 seconds on each key-on, after the
hourmeter is displayed.
The Spyglass is available in 3-LED and 6-LED models; see Figure 21.

STATUS LED DIAGNOSTICS
A Status LED is built into the 1243GEN2 controller. It is visible through a
window in the label on top of the controller. This Status LED displays fault
codes when there is a problem with the controller or with the inputs to the
controller. During normal operation, with no faults present, the Status LED
flashes steadily on and off. If the controller detects a fault, a 2-digit fault
identiﬁcation code is flashed continuously until the fault is corrected. For
example, code “3,2”—main contactor welded—appears as:
¤¤¤ ¤¤ ¤¤¤ ¤¤ ¤¤¤ ¤¤

FAULT OUTPUT LED DIAGNOSTICS
The 1243GEN2 controller provides two fault outputs designed to transmit fault
information to LEDs located on the display panel or on any remote panel. These
outputs can be programmed to display faults in Fault Code format or in Fault
Category format—see Section 3, page 51.
In Fault Code format, the two fault outputs operate independently. The
Fault 1 line flashes the same codes, at the same time, as the controller’s built-in
Status LED (see Table 8). The Fault 2 line pulls low when a fault is present; it
can be used to drive an LED that simply indicates whether or not there is a fault.
When no faults are present, both of the fault lines are in their normal state
(high).
In Fault Category format, the two fault outputs together deﬁne one of
four fault categories, as listed in Table 9. When a fault occurs, the Fault 1 and
Fault 2 lines (Pins 2 and 3) go to the state indicating the category of the
particular fault: LOW/HIGH, HIGH/LOW, or LOW/LOW. When the fault is cleared,
the fault outputs return to their normal state (i.e., HIGH/HIGH).

CONTROLLER MAINTENANCE
There are no user serviceable parts in the Curtis 1243GEN2 controller. No
attempt should be made to open, repair, or otherwise modify the controller.
Doing so may damage the controller and will void the warranty.
It is recommended that the controller be kept clean and dry and that its
fault history ﬁle be checked and cleared periodically.
CLEANING
Periodically cleaning the controller exterior will help protect it against corrosion
and possible electrical control problems created by dirt, grime, and chemicals
that are part of the operating environment and that normally exist in battery
powered systems.
When working around any battery powered vehicle, proper safety precau-
tions should be taken. These include, but are not limited to: proper training,
wearing eye protection, and avoiding loose clothing and jewelry.
Use the following cleaning procedure for routine maintenance.
1. Remove power by disconnecting the battery.
2. Discharge the capacitors in the controller by connecting a load
(such as a contactor coil or a horn) across the controller’s B+ and
B- terminals.
3. Remove any dirt or corrosion from the connector areas. The
controller should be wiped clean with a moist rag. Dry it before
reconnecting the battery. The controller should not be subjected
to pressured water flow from either a standard hose or a power
washer.
4. Make sure the connections are tight, but do not overtighten
them. See Section 2, page 7, for maximum tightening torque
speciﬁcations for the battery and motor connections.
FAULT HISTORY FILE
The handheld programmer can be used to access the controller’s fault history
ﬁle. The programmer will read out all the faults the controller has experienced
since the last time the history ﬁle was cleared. Faults such as contactor faults may
be the result of loose wires; contactor wiring should be carefully checked. Faults
such as overtemperature may be caused by operator habits or by overloading.
After a problem has been diagnosed and corrected, it is a good idea to
clear the fault history ﬁle. This allows the controller to accumulate a new ﬁle of
faults. By checking the new history ﬁle at a later date, you can readily determine
whether the problem was indeed ﬁxed.
For instructions on accessing the history ﬁle, see Appendix B.

APPENDIX A: EMC & ESD DESIGN CONSIDERATIONS
APPENDIX A
VEHICLE DESIGN CONSIDERATIONS
REGARDING ELECTROMAGNETIC COMPATIBILITY (EMC)
AND ELECTROSTATIC DISCHARGE (ESD)
ELECTROMAGNETIC COMPATIBILITY (EMC)
Electromagnetic compatibility (EMC) encompasses two areas: emissions and
immunity. Emissions are radio frequency (rf) energy generated by a product.
This energy has the potential to interfere with communications systems such as
radio, television, cellular phones, dispatching, aircraft, etc. Immunity is the
ability of a product to operate normally in the presence of rf energy.
EMC is ultimately a system design issue. Part of the EMC performance
is designed into or inherent in each component; another part is designed into
or inherent in end product characteristics such as shielding, wiring, and layout;
and, ﬁnally, a portion is a function of the interactions between all these parts.
The design techniques presented below can enhance EMC performance in
products that use Curtis motor controllers.
Decreasing Emissions
Motor brush arcing can be a signiﬁcant source of rf emissions. These emissions
may be reduced by installing bypass capacitors across the motor wires and/or
between each motor wire and the motor frame. If the latter approach is used, the
voltage rating and leakage characteristics of the capacitors must be adequate to
meet any safety regulations regarding electrical connections between a battery
operated circuit and the chassis. The bypass capacitor should be installed as close
to the motor as possible, or even inside it, to provide the best performance.
Alternatively a ferrite bead can be installed on the wires, as close as possible to
the motor. In some instances, capacitors and ferrite beads may both be appro-
priate. Another option is to choose a motor with a brush material that will result
in less arcing to the commutator. Brushes that have been run in for approxi-
mately 100 hours will typically generate lower emissions than new brushes
because there is less arcing after they are properly seated.
The motor drive output from Curtis controllers can also make a contri-
bution to rf emissions. This output is a pulse width modulated square wave with
rather fast rise and fall times that are rich in harmonics. The impact of these
switching waveforms can be minimized by making the wires from the controller
to the motor as short as possible. Ferrite beads installed on the drive wires can
further reduce these emissions. For applications requiring very low emissions,
the solution may involve enclosing the controller, interconnect wires, and
motor together in one shielded box. The motor drive harmonics can couple to
battery supply leads and throttle circuit wires, so ferrite beads may also be
required on these other wires in some applications.
Curtis 1243GEN2 Manual
A-2
APPENDIX A: EMC & ESD DESIGN CONSIDERATIONS
Increasing Immunity
Immunity to radiated electric ﬁelds can be achieved either by reducing the
overall circuit sensitivity or by keeping the undesired signals away from this
circuitry. The controller circuitry itself cannot be made less sensitive, since it
must accurately detect and process low level signals from the throttle potenti-
ometer. Thus immunity is generally achieved by preventing the external rf
energy from coupling into sensitive circuitry. This rf energy can get into the
controller circuitry via conducted paths and via radiated paths.
Conducted paths are created by the wires connected to the controller.
These wires act as antennas and the amount of rf energy coupled into these
wires is generally proportional to their length. The rf voltages and currents
induced in each wire are applied to the controller pin to which the wire is
connected. Curtis motor controllers include bypass capacitors on the printed
circuit board’s throttle wires to reduce the impact of this rf energy on the
internal circuitry. In some applications, ferrite beads may also be required on
the various wires to achieve desired performance levels.
Radiated paths are created when the controller circuitry is immersed in an
external ﬁeld. This coupling can be reduced by enclosing the controller in a
metal box. Some Curtis motor controllers are enclosed by a heat sink that also
provides shielding around the controller circuitry, while others are unshielded.
In some applications, the vehicle designer will need to mount the controller
within a shielded box on the end product. The box may be constructed of just
about any metal, although steel and aluminum are most commonly used.
Most coated plastics do not provide good shielding because the coatings
are not true metals, but rather a mixture of small metal particles in a non-
conductive binder. These relatively isolated particles may appear to be good
based on a dc resistance measurement but do not provide adequate electron
mobility to yield good shielding effectiveness. Electroless plating of plastic will
yield a true metal and can thus be effective as an rf shield, but it is usually more
expensive than the coatings.
A contiguous metal enclosure without any holes or seams, known as a
Faraday cage, provides the best shielding for the given material and frequency.
When a hole or holes are added, rf currents flowing on the outside surface of the
shield must take a longer path to get around the hole than if the surface was
contiguous. As more “bending” is required of these currents, more energy is
coupled to the inside surface, and thus the shielding effectiveness is reduced.
The reduction in shielding is a function of the longest linear dimension of a
hole rather than the area. This concept is often applied where ventilation is
necessary, in which case many small holes are preferable to a few larger ones.
Applying this same concept to seams or joints between adjacent pieces or
segments of a shielded enclosure, it is important to minimize the open length
of these seams. Seam length is the distance between points where good ohmic
contact is made. This contact can be provided by solder, welds, or pressure
contact. If pressure contact is used, attention must be paid to the corrosion
characteristics of the shield material and any corrosion-resistant processes
Curtis 1243GEN2 Manual
A-3
APPENDIX A: EMC & ESD DESIGN CONSIDERATIONS
applied to the base material. If the ohmic contact itself is not continuous, the
shielding effectiveness can be maximized by making the joints between adjacent
pieces overlapping rather than abutted.
The shielding effectiveness of an enclosure is further reduced when a wire
passes through a hole in the enclosure. RF energy on the wire from an external
ﬁeld is re-radiated into the interior of the enclosure. This coupling mechanism
can be reduced by ﬁltering the wire at the point where it passes through the
boundary of the shield. Given the safety considerations involved with connect-
ing electrical components to the chassis or frame in battery powered vehicles,
such ﬁltering will usually consist of a series inductor (or ferrite bead) rather than
a shunt capacitor. If a capacitor is used, it must have a voltage rating and leakage
characteristics that will allow the end product to meet applicable safety regula-
tions.
The B+ (and B-, if applicable) wires that supply power to the throttle
control panel—such as for the keyswitch—should be bundled with the remain-
ing throttle wires so that all these wires are routed together. If the wires to the
control panel are routed separately, a larger loop area is formed. Larger loop
areas produce more efﬁcient antennas which will result in decreased immunity
performance.
ELECTROSTATIC DISCHARGE (ESD)
Curtis motor controllers contain ESD-sensitive components, and it is therefore
necessary to protect them from ESD damage. Electrostatic discharge (ESD)
immunity is achieved either by providing sufﬁcient distance between conduc-
tors and the outside world so that a discharge will not occur, or by providing an
intentional path for the discharge current such that the circuit is isolated from
the electric and magnetic ﬁelds produced by the discharge. In general the
guidelines presented above for increasing the radiated immunity will also
provide increased ESD immunity.
It is usually easier to prevent the discharge from occurring than to divert
the current path. A fundamental technique for ESD prevention is to provide
adequately thick insulation between all metal conductors and the outside
environment so that the voltage gradient does not exceed the threshold required
for a discharge to occur. If the current diversion approach is used, all exposed
metal components must be grounded. The shielded enclosure, if properly
grounded, can be used to divert the discharge current; it should be noted that
the location of holes and seams can have a signiﬁcant impact on the ESD
suppression. If the enclosure is not grounded, the path of the discharge current
becomes more complex and less predictable, especially if holes and seams are
involved. Some experimentation may be required to optimize the selection and
placement of holes, wires, and grounding paths. Careful attention must be paid
to the control panel design so that it can tolerate a static discharge.

The bookmark keys allow you to quickly go back to up to three selected
items without having to navigate back through the menu structure. To set a
bookmark, press one of the bookmark keys for about three seconds, until the
Bookmark Set screen is displayed. To jump to a set bookmark location, quickly
press the appropriate bookmark key (1, 2, or 3). Note that the bookmarks are
not permanently stored in the programmer. They are cleared when the pro-
grammer is unplugged.
The bookmark keys can be used to make parameter adjustment easier. For
example, in adjusting the throttle deadband, you might set a bookmark at the
Throttle % readout [Monitor > THROTTLE %] and another at the Throttle
Deadband parameter [Program > THROTTLE DB]; this way you can easily toggle
between the readout and the parameter.

A Status LED is built into the 1243

window in the label on top of the controller. This Status LED displays fault

codes when there is a problem with the controller or with the inputs to the

controller. During normal operation, with no faults present, the Status LED

flashes steadily on and off. If the controller detects a fault, a 2-digit fault

identiﬁcation code is flashed continuously until the fault is corrected. For

example, code «3,2»—main contactor welded—appears as:

Просто из любопытства переключил контроллер в режим speed mode express в котором он управляет оборотами двигателя а не крутящим моментом и вуаля — мотор покорно слушается педали… но ведь в таком режиме него нельзя применять в электромобиле, или можно??? Кто может подсказать?

Всё можно. Просто torque mode чуть более «естественен» по оклику. Но это надо сначала сравнить и почувствовать разницу.

Вот, собственно, это и интересно. Единственная разница в настройках этих режимов в том что в управлении крутящим моментом есть еще настройки симуляции автоматической коробки передач и есть подозрение, что он просто не будет работать без педали тормоза ведь она критично важна для автоматической коробки. А педаль тормоза у меня отключена. Хотя ее можно включить на обычную кнопку(лягушку на стандартной педали тормоза) 0-100% тогда и регенеративное торможение работать будет от легкого касания педали.

Еще один вопрос — настройка скольжения.
Я, если честно, начинаю путаться: везде в литературе пишут число ПАР полюсов. А в мануале куртиса написано «число полюсов» от 2 до 8. Если на схеме написано «Число полюсов 2р=6» это значит что у меня три пары полюсов или просто шесть полюсов?
Тогда как рассчитать скольжение в моем случае? Макс обороты двигателя 6000 об/мин макс частота контроллера 300Гц. Число полюсов 2р=6.
По формуле расчета скольжения для обычного двигателя, включенного в сеть получается какая-то несуразица. Так еще и в контроллере значение скольжения задается от 0 до 200 единиц, а мануал ни чего об этом не говорит, а предлагает позвонить куртисовцам…

Здрасте всем :-)
Есть первая победа над куртисом, к сожалению и последняя в этом году, так как хранить в собранном виде машинку негде, так что зимовать электроника будет дома.

Кратко: АКБ стартерные, подешевле, временные. 75 Вольт 60Ач. Контроллер куртис 1236-6301, двигатель асинхронный на совмещенных обмотках.
Контроллер настраиваю через ноутбук с СОМ портом и софтиной, гуляющей в свободном доступе по интернетам.
Рама послужит еще испытательным стендом, но буду делать сварную из трубы — наигрался с листовой сталью. Опыт — сын ошибок трудных :sorry:
На севших аккумах при 72В и просадке до 65(установил сам что бы не убить раньше времени аккумуляторы) осмелился разогнаться до 60 км/ч — было страшно.

У меня такой же контроллер. Управления по моменту даже нет в настройках.

Вопрос как подключили контактор? Вроде собрал все по схеме — не работает. Включаю KSI и тишина. Еще не могу избавиться от ошибки PDO Timeout.

Если контроллер такой-же то очень странно что нет управления моментом. Это цифра «2» в настройках. «0» это управление оборотами с минимальными настройками, «1» то же но с развернутыми настройками.
Сейчас все подключено как в мануале показано. Но в будущем переделаю на управление через БМС Юрия Логвина. Она будет управлять KSI а не через тумблер как сейчас.
В настройки CAN шины я не лазил так как не использую ее. Но вообще ваша ошибка ругается на неправильно заданный таймаут PDO Timeout Period
Свою прошивку сохранял. Сейчас покопаюсь — найду.

Доброго дня!
У меня нет программы и «шнурка».
Как то лазил в 1221 (не было выхода на контактор), драйвер контактора в аналоговом контроллере состоял из полевого транзистора, операционного усилителя компаратора 293 , низкоомного резистора (токовый шунт для контроля тока обмотки катушки контактора?) и какой-то цифровой микросхемы. Но в моем случае дело было не в драйвере контактора, как оказалось. При замене деталей по питанию (оказывается внутрь корпуса контроллера попадала вода) начал срабатывать контактор,все заработало.
В целом мало в этом соображаю, но представляю себе примерно так: подается питание и контроллером производится диагностика, если все нормально и далее если водитель производит правильную последовательность включения (там HPD и прочее), то все должно заработать.
Если Ваш контроллер кодирует ледом ошибку и указывает на:
1.Main contactor stuck closed.
2.Main contactor driver shorted.
То надо выполнить:
Check wiring and contactor,
затем: cycle KSI.
1.Stuck я не знаю что такое (google translate дает: «главный контактор заклинило»), может быть главные/силовые контакты (или якорь контактора заклинило мусором и пр.?)?
2.Закорочен драйвер главного контактора (google translate дает: «главный контактор закорочен»)?
То есть необходимо проверить внешние цепи от контроллера к контактору, можно прозвонить обмотку контактора, как правило они не более чем 1 амперные. Проверить главные контакты. Проверить механику якоря контактора и т.п.
Cycle KSI — выключить питание (замок), все проверить/устранить, затем включить питание (замок).
Затем уже, например, из любопытства, можно залезть внутрь контроллера и посмотреть что там и как.
1243-это для SepEx двигателя?
А у Вас какая техника?

Еще такой вопрос. Контроллер постоянно проверяет наличие двигателя. Т.е. «щупает» он его клеммами М- и B+. Вопрос в том, как он это делает? Как контроллер понимает , что двигатель подключен? Кертис делает это через замер сопротивления или индукции?

Уже писал, в этом мало понимаю, не могу сказать.
Но почитать об этом-всегда интересно!
К тому же, Sepex контроллер, наверно, должен щупать не только цепь «арматуры» но и цепь обмоток.
Автор этой темы реализовал самодельный SepEx контроллер, если я не ошибаюсь.

Доброго всем.
Тут вопрос уже поднимался — как разобрать контроллер для ремонта — он залит резиновым компаундом, с боков пластиковые крышки, снизу 6 винтов сквозь корпус в радиатор.
Винты открутил, заднюю крышку начал отковыривать — ломается у корпуса а далее насмерть приклеена — боюсь пока что-то далее делать.

Здравствуйте,

Нагреть феном компаунд и прорезать ножом весь периметр компаунда, ограничив глубину погружения ножа.
Тянуть (предварительно открутив винты в основании) за шину М- можно уверенно, а за шины B+ и B- осторожно, не сильно. За шину А2 вообще не стоит тянуть.

Спасибо большое, прояснилось.
Нашёл как вскрывали похожий блок и там же есть много по доработке, и ремонту…
ссылка

Вот мой процесс вскрытия в картинках может кому поможет тоже:
Начал отковыривать по периметру без нагрева-

оторвал шильдик чтобы не сплавился от строительного фена — с ним правдо пошло легче

с боку были какие-то винты — при вскрытии задней стенки — она вся сломалась увидел что они просто вкручены и ничего не держат. пошевелил плату и радиатор — оторвал всё от корпуса и всё легко задвигалось вверх/вниз, а так была прилипшая и просто вытягивать вперёд думаю бы было очень трудно.

Перешел к нагреву переда и подковыриванию с боков.

В итоге проковыряв всё по периметру чуток и шевеля за «попу» плату и радиатор перед зашевелился ещё легче и подался вперёд — даже за концы не тянул.

При осмотре платы ни дыма ни копоти не видать… видимо управляйка сдохла.. будем курить…

1 Моргает 02, НЕ1.1 !!!
2 напряжение на об. возбуждения не подаётся,
3 при замыкании сигнала с проца на минус вращение прекращается.
Делаю вывод, что проблема с процом, буду отдавать хозяину.
Для очистки совести, создал тему, может что упустил.

Сложно сказать не имея принципиалки, там, скорее всего, кроме проца и обвязки и нет ничего.

24 Апр 2020

Ну большая часть принципиалки у меня нарисована, но
1 Коды ошибок прописаны в ВИОС проца и если он отсутствует в мануале, то и недоступен простым смертным
2 Чтобы запустить двигатель, надо сначала подать напряжение на обмотку возбуждения (чего нет) а потом на щётки
3 Потому и думаю, что налицо явная ошибка алгоритма сброса проца
4 Вот и слабая надежда на то что кто то уже менял проц по такой ошибке

Штабелер Noblelift не двигается вперед

На штабелере во время работs загорелась ошибка 1-3 и при этом он перестал двигаться вперед. Проверка электропроводки, двигателя и периферии показала, что в них неисправностей нет, и остается одно — неисправность контролера движения CURTIS CLB1236 компании SepEx.

Данный блок был привезен нашему схематехнику с целью его диагностики и дальнейшего ремонта. Диагностика выявила, что в штабелерте было короткое замыкание которое и привело к выходу из строя контролера CLB1236.

В ходе ремонтных работ были заменены сгоревшие элементы. После ремонта была проведена повторная компьютерная диагностика с целью проведения тестов-проверок, которые показали, что блок CLB1236 полностью готов к установке на штабелер.

Сама по себе стоимость этих блоков не так высока, но есть один большой нюанс, под каждую технику эти контролеры идут с разным программным обеспечением и купить контролер CURTIS с нужным ПО это очень не простая задача. Так же по мимо различного ПО эти модули различаются по силовому напряжению питания — 24В и 36В.

Эти модули в большинстве случаев выходят из строя по причине короткого замыкания в моторе или электропроводке, либо человеческий фактор (например: не отключенное электропитание при демонтаже мотора).

Наша компания осуществляет ремонт любых контролеров CURTIS.
