12 Troubleshooting

12-3 Errors

If the Servo Drive detects an abnormality, it outputs an error (/ERR), turns OFF the power drive circuit,

and displays the error number (main and sub) on the front panel.

Precautions for Correct Use

• Refer to 12-5-1 Troubleshooting Using Error Displays on page 12-14 for information on trou-

bleshooting.

• You can reset the error by turning OFF the power supply and then ON again, or executing the

error reset command via EtherCAT communications or on the Sysmac Studio. Be sure to

remove the cause of the error first.

• Some errors are reset only by turning the power supply OFF then ON again. For details, refer

to 12-3-1 Error List on page 12-10.

• If nothing is displayed on the 7-segment display even when the control power supply is ON, it

indicates that the internal MPU is malfunctioning. If you find this symptom, cut off the power

supply immediately.

7-9 Soft Start Function
This function sets the acceleration and deceleration against the velocity command input inside the 
Servo Drive and uses these values for speed control.
With this function, soft starts are possible when the step rotation velocity commands are input. To 
reduce any impacts made by acceleration changes, you can also use the velocity command filter 
(first-order lag).
For a step velocity command input, set the time until the velocity command reaches 1,000 r/min in 
Acceleration Time.
Similarly, set the time until the velocity command slows from 1,000 r/min down to 0 r/min in Decelera-
tion Time.
Acceleration Time (ms) = Vc/1,000 r/min × Acceleration Time × 0.1 ms
Deceleration Time (ms) = Vc/1,000 r/min × Deceleration Time × 0.1 ms

AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
1-1 Outline
The 1S-series Servo Drives with Built-in EtherCAT communications support 100-Mbps EtherCAT.
When you use the 1S-series Servo Drive with a Machine Automation Controller NJ/NX-series CPU Unit 
or Position Control Unit with EtherCAT (Model: CJ1W-NC8), you can construct a high-speed and 
sophisticated positioning control system.
You need only one communications cable to connect the Servo Drive and the Controller. Therefore, you 
can realize a position control system easily with reduced wiring effort.
With adjustment functions, adaptive notch filter, notch filter, and damping control, you can set up a sys-
tem that provides stable operation by suppressing vibration in low-rigidity machines.
Moreover, with the two-degree-of-freedom (TDF) control structure, you can easily adjust high-precision 
positioning.
The 1S-series Servo Drives have the following features.
As a Sysmac Device, 1S-series Servo Drives with built-in EtherCAT communications is designed to 
achieve optimum functionality and ease of operation when it is used together with the NJ/NX-series 
Machine Automation Controller and the Sysmac Studio Automation Software.
Sysmac Device is a generic term for OMRON control devices such as an EtherCAT Slave, designed 
with unified communications specifications and user interface specifications.
Combining the 1S-series Servo Drive with a Machine Automation Controller NJ/NX-series CPU Unit or  
Position Control Unit with EtherCAT (Model: CJ1W-NC8) enables you to exchange all position 
information with the controller in high-speed data communications.
Since the various control commands are transmitted via data communications, Servomotor’s opera-
tional performance is maximized without being limited by interface specifications such as the response 
frequency of the encoder feedback pulses.
You can use the Servo Drive’s various control parameters and monitor data on a host controller, and 
unify the system data for management.
Combination with an NX7 Machine Automation Controller enables high-speed and high-precision 
motion control at the communications cycle of 125 µs.
The 400-V models are provided for use with large equipment, at overseas facilities and in wide-ranging 
applications and environment. Since the utilization ratio of facility equipment also increases, the TCO 
(Total Cost of Ownership) will come down.

You can cut off the motor current to stop the motor based on a signal from an emergency stop button or 
other safety equipment. This can be used for an emergency stop circuit that is compliant with safety 
standards without using an external contactor. Even during the torque OFF status, the present position 
of the motor is monitored by the control circuits to eliminate the need to perform the homing at the time 
of restart.
You can use NX-series Safety Control Units to integrate safety controls in a sequence and motion con-
trol system.
The 1S-series Servo Drive supports the FSoE (Safety over EtherCAT) protocol as the safety com-
munincations. You can build the safety system that uses the STO function from the safety controller on 
the EtherCAT network.
The damping control function suppresses vibration of low-rigidity machines or devices whose tips tend 
to vibrate. The function can also be used for damping control for larger constructions as it supports 
vibration ranging from 0.5 to 300 Hz. You can maximize the performance of the Servomotor by 
adjusting the trade-off between the damping time and the amount of peak control.
The TDF control structure allows you to separately adjust the amount of overshooting and the 
resistance against disturbance. With this feature, you can easily achieve high-precision positioning, 
which is difficult to achieve with the one-degree-of-freedom (ODF) control.
EtherCAT is an open high-speed industrial network system that conforms to Ethernet (IEEE 802.3). 
Each node achieves a short communications cycle time by transmitting Ethernet frames at high speed. 
A mechanism that allows sharing clock information enables high-precision synchronization control with 
low communications jitter.

2-4-3  Decelerator Dimensions
The following tables show the dimensions of Decelerators.
z For 3,000-r/min Servomotors (100 to 200 W)
*1. Two set bolts are positioned at 90° from each other.
*2. D6 is the maximum diameter of the decelerator body between the flange side and Servomotor side. 
(Refer to the Outline Drawing) The value is given only when the diameter is larger than the diameters of these two sides. 
Take heed of this when you mount the decelerator to the machine.
*3. Indicates set bolt.
Note 1. The standard shaft type is a straight shaft.
2. A model with a key and tap is indicated with “J” at  of the model number. (Example: 
R88G-HPG11B05100BJ)
3. The diameter of the motor shaft insertion hole is the same as the shaft diameter of the corresponding 
Servomotor.
4. You cannot use this type of Decelerator for the Servomotor with key.
5. The dimensional drawings in this document are for showing main dimensions only, and they do not give 
the details of the product shape.

Precautions for Correct Use
Use a commercially available USB cable that is double-shielded, gold-plated, and supports 
USB 2.0. The Micro B type USB cable can be used.
This section gives the time from when the control power supply for the Servo Drive is turned ON until 
the control I/O and EtherCAT communications are enabled.
Communications with the master is started after the EtherCAT communications are enabled. Perform 
Servo ON and send commands only after the EtherCAT communications are established.

AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
The overload protection function (electronic thermal) is built into the Servo Drive to protect the Servo 
Drive and Servomotor from overloading.
If an overload occurs, first eliminate the cause of the overload and then wait for the Servomotor 
temperature to drop before you turn ON the power again.
If the error reset is repeated at short intervals, the Servomotor windings may burn out.
The following graphs show the electronic thermal operation time after continuous operation with 100% 
load (hot start).
The electronic thermal operation time after a continuous 0% load state (cold start) is longer than that for 
a hot start.
In cases where models with an oil seal or with a brake have different characteristics, each of their char-
acteristics is described. 
The characteristics are the same as those of models with no option unless otherwise specified.

z Torque-Rotation Speed Characteristics for 3,000-r/min Servomotors (400 
VAC)
The following graphs show the characteristics with a 3-m standard cable and a 400-VAC input.
• R88M-1L75030C • R88M-1L1K030C • R88M-1L1K530C
• R88M-1L2K030C • R88M-1L3K030C
Note The continuous operation range is the range in which continuous operation is possible at an ambient tem-
perature of 40°C when the Servomotor is horizontally installed on a specified radiator plate. 
Continuous operation at the maximum speed is also possible. However, doing so will reduce the output 
torque.

If the cable is used in a moving part, use a flexible cable.
The flexing life of a Flexible Cable is estimated under the following conditions.
Precautions for Correct Use
• Because the lifetime data on resistance to bending is intended for reference only, use the 
cable with a sufficient margin.
• The minimum bending radius refers to the value at which the core conductor provides electri-
cal continuity without causing cracks and scratches that can have functional impact on the 
sheath, which does not cover the disconnection of shielded wire.
• Malfunction or grounding fault due to dielectric breakdown may occur if cables are used at a 
radius smaller than the minimum bending radius.

AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
For the EtherCAT communications cable, use a twisted-pair cable, which is doubly shielded by the alu-
minum tape and braid, with Ethernet Category 5 (100BASE-TX) or higher.
Recommended cables are shown below.
Precautions for Correct Use
The maximum cable length between nodes is 100 m. However, some cables are specified for 
less than 100 m. Generally speaking, if the conductor is twisted wire rather than solid wire, 
transmission performance will be lower, and reliable communications may not be possible at 
100 m. Confirm details with the cable manufacturer.
Additional Information
If an Ethernet cable of Ethernet Category 5 (100BASE-TX) or higher is used, communications 
will be possible even if the cable is not shielded. However, we recommend a cable, which is 
doubly shielded by the aluminum tape and braid, to ensure sufficient noise immunity.
Use a shielded connector of Ethernet Category 5 (100BASE-TX) or higher.
Recommended connectors are shown below.
Precautions for Correct Use
When you select a connector, confirm that it is applicable to the cable that will be used. Confirm 
the following items: Conductor size, conductor type (solid wire or twisted wire), number of 
twisted pairs (2 or 4), outer diameter, etc.

Turn the bottom of Servo Drive in the gravity direction.
The environment in which the Servo Drive is operated must meet the following conditions. The Servo 
Drive may malfunction if it is operated under any other conditions.
• Operation in an environment in which there is minimal temperature rise is recommended to maintain 
a high level of reliability.
• When the Servo Drives are installed in a closed space, such as a box, the ambient temperature may 
rise due to the heat that is generated from each unit. Use a fan or air conditioner to maintain ambient 
temperature of the Servo Drive under the operating environment conditions.
• The Servo Drive surface may rise in temperature of 30°C above the ambient temperature. Use 
heat-resistant materials for wiring, and provide a distance from any devices or wiring that are sensi-
tive to heat.
• The use of the Servo Drive in a hot environment shortens its lifetime.
When you use the Servo Drive in continuous operation, use a fan or air conditioner to maintain the 
ambient temperature at or below 40°C.

4-1-2  Servomotor Installation Conditions
• Take measures during installation and operation to keep foreign objects such as metal particles, oil, 
machining oil, dust, or water out of the Servo Drive.
• Place a cover over the Servo Drive or take other preventative measures to keep foreign objects, such 
as drill filings, out of the Servo Drive during installation. Be sure to remove the cover after installation 
is complete. If the cover is left on during operation, heat dissipation from the Servo Drive is blocked, 
which may result in malfunction.
• The environment in which the Servomotor is operated must meet the following conditions. Operating 
the Servomotor outside of the following ranges may result in malfunction of the Servomotor.
Operating temperature: 0 to 40°C (The temperature at a point 50 mm from the Servomotor)
Operating humidity: 20% to 90% max. (with no condensation)
Operating ambient atmosphere: No corrosive gases.
• The Servomotor is resistant to vibration of up to 49 m/s
2
.
• If the Servomotor is mounted on a thin plate, the rigidity 
may decrease and severe vibration may occur.
• The Servomotor is resistant to impacts of up to 98 m/s
2
. 
Do not apply heavy impacts or loads during transport, 
installation, or removal of the Servomotor.
• When transporting the Servomotor hold the motor body 
itself. And do not hold the encoder, cable, or connector 
areas. Failure to follow this guideline may result in damaging the Servomotor.
• Always use a pulley remover to remove pulleys, couplings, or other parts from the shaft.
• Connect cables and connectors carefully so that they are not strained. After assembly, secure cables 
so that there is no impact or load placed on the cable outlet.
• As a magnetic sensor is used for the encoder of the Servomotor, do not apply external magnetic 
force on the Servomotor (10 mT at the encoder cover surface).

AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
• For the allowable axial loads for Servomotors, refer to 
3-2-3 Characteristics on page 3-30. If an axial load 
greater than that specified is applied to a Servomotor, it 
may reduce the limit of the motor bearings and may 
break the motor shaft.
• When you connect the Servomotor to a load, use cou-
plings that can sufficiently absorb mechanical eccentric-
ity and declination.
• When you connect or disconnect loads (or couplings) to 
or from the Servomotor, be careful not to apply an 
impact on the motor shaft. Do not allow the thrust load 
and radial load to exceed the values that are specified in 
the manual or catalog while you connect a load to the 
Servomotor.
• If an abnormal noise is generated from couplings, adjust 
the shaft center again to eliminate the noise.
• When you align the shaft center of the couplings, turn 
both the Servomotor side shaft and equipment side 
shaft.
• For spur gears, an extremely large radial load may be 
applied depending on the gear precision. Use spur 
gears with a high degree of precision (for example, JIS 
class 2: normal line pitch error of 6 µm max. for a pitch 
circle diameter of 50 mm).
• If the gear precision is not adequate, allow backlash to 
ensure that no radial load is placed on the motor shaft.
• When you use bevel gears, a load is applied in the 
thrust direction depending on the assembly precision, 
the gear precision, and temperature changes. Provide 
appropriate backlash or take other measures to ensure that a thrust load larger than the specified 
level is not applied.
• Do not put rubber packing on the flange surface. If the flange is mounted with rubber packing, the 
Servomotor flange may crack under the tightening force.
• When you connect the Servomotor to a V-belt or timing belt, consult the manufacturer for belt selec-
tion and tension.
• A radial load twice as large as the belt tension will be placed on the motor shaft. Do not allow a load 
that exceeds the allowable radial load to be placed on the motor shaft. If an excessive radial load is 
applied, the motor shaft and bearings may be damaged.
Set up a movable pulley in the middle of the motor shaft and the load shaft so that the belt tension 
can be adjusted.
Install the Servo Drive so that its bottom faces the gravity direction.

4-1-2  Servomotor Installation Conditions
The protective structure rating of the Servomotor is IP67, except for the through-shaft part and connec-
tor pins.
It is IP20 if you use a 30-meter or longer encoder cable.
Use the Servomotor with an oil seal if you use it in an environment where oil drops can adhere to the 
through-shaft part. The operating conditions of the Servomotor with an oil seal are as follows:
• Keep the oil level below the lip of the oil seal.
• Prepare a good lubricated condition under which only oil droplets splash on the oil seal.
• If you use the Servomotor with the shaft in upward direction, make sure that no oil accumulates on 
the lip of the oil seal.
When you mount a Servomotor onto a small device, be sure to provide enough radiation space on the 
mounting area because the heat is radiated from the mounting surface. Otherwise the Servomotor tem-
perature may rise too high. One of the preventive measures is to install a radiator plate between the 
motor attachment area and the motor flange. (See the following figure)
Failure to follow this guideline may result in damaging the Servomotor due to a temperature rise. 
Refer to
3-2 Servomotor Specifications on page 3-28 for the radiator plate specifications.
• The temperature rise depends on the mounting part materials and the installation environment. 
Check the actual temperature rise by using a real Servomotor.
• Depending on the environment, such as when the Servomotor is installed near a heating element, 
the Servomotor temperature may rise significantly. In this case, take any of the following measures.
a) Lower the load ratio.
b) Review the heat radiation conditions of the Servomotor.
c) Install a cooling fan and apply forced air cooling to the Servomotor.

Take measures to protect the motor shaft from corrosion. The motor shaft is coated with anti-corrosion 
oil when it is shipped, but you should also apply anti-corrosion oil or grease when you connect the com-
ponents that apply load to the shaft.
Other Precautions
Caution
Do not repair the Servo Drive by disassembling it.
Electric shock or injury may result.
Do not apply a commercial power supply directly to 
the motor.

*1. Recommended products are listed in 4-3 Wiring Conforming to EMC Directives on page 4-29. This connection example 
is for when the book-type noise filter is used. When you use the footprint-type noise filter, built the system to directly con-
nect the noise filter and the Servo Drive.
*2. There is no polarity on the brakes.
*3. Short-circuit B2 and B3 for models with a built-in regeneration resistor (1SN04L-ECT and 1SN08H-ECT). When the 
amount of regeneration is large, remove the short-circuit wire between B2 and B3 and connect a regeneration resistor 
between B1 and B2.
*4. There is no internal regeneration resistor for 1SN01L-ECT to 1SN02L-ECT and 1SN01H- ECT to 1SN04H-ECT. When 
the amount of regeneration is large, connect the necessary regeneration resistor between B1 and B2.
*5. To ensure safety, install a leakage breaker for the main circuit power supply input in the control panel. Refer to 4-3-2 
Selecting Connection Component on page 4-39.
*6. When the DC reactor is not used, short-circuit N1 and N2.
When the DC reactor is used, remove the short-circuit wire between N1 and N2, and connect the DC reactor between 
N1 and N2.
*7. External connection components are not required because a brake relay and a surge absorbing element are built into 
the Servo Drive.

*1.  Recommended products are listed in 4-3 Wiring Conforming to EMC Directives on page 4-29. This connection example 
is for when the book-type noise filter is used. When you use the footprint-type noise filter, built the system to directly con-
nect the noise filter and the Servo Drive.
*2.  There is no polarity on the brakes.
*3. Short-circuit B2 and B3 for models with a built-in regeneration resistor (1SN08H-ECT). When the amount of regenera-
tion is large, remove the short-circuit wire between B2 and B3 and connect a regeneration resistor between B1 and B2.
*4. There is no Internal Regeneration Resistor for 1SN01H-ECT to 1SN04H-ECT. When the amount of regeneration is 
large, connect the necessary Regeneration Resistor between B1 and B2.
*5. To ensure safety, install a leakage breaker for the main circuit power supply input in the control panel. Refer to 4-3-2 
Selecting Connection Component on page 4-39.
*6. When the DC reactor is not used, short-circuit N1 and N2.
When the DC reactor is used, remove the short-circuit wire between N1 and N2, and connect the DC reactor between 
N1 and N2.
*7. External connection components are not required because a brake relay and a surge absorbing element are built into 
the Servo Drive.

The procedure for wiring connector-type terminal blocks is explained below.
Precautions for Correct Use
Wear the protective equipment when you perform the task. Do not apply any force to the 
opener (Servo Drive’s accessory) after its protrusion reaches the bottom dead center. As a 
guide, do not apply the force of 100 N or more.
1 Remove the terminal block from the Servo Drive before wiring.
The Servo Drive may be damaged if the wiring is done with the terminal block in place.
2 Strip off the covering from the wire.
Refer to
Terminal Block Wire Sizes on page 3-11 for applicable wire sizes. If the stripped wire is 
bended, loose or too large in diameter due to twist, retwist it gently and check its strip length by 
the use of a gauge before you use it. Smoothen the cut surface of wires and the stripped sur-
face of covering. Or, you can use a ferrule.

3 Connect the wires.
Insert the hook of the spring opener into a square hole located on the same side as the wire 
holes, and use your thumb to press down the lever of the spring opener until it clicks into place. 
Insert the wire fully into the back of a wire hole while the lever of the spring opener is held down. 
Release the lever, and then pull the wire gently to check that it does not come out.
4 Mount the terminal block to the Servo Drive.
After all of the terminals are wired, return the terminal block to its original position on the Servo 
Drive.
Note The wire may not be inserted easily depending on the shape of the ferrule connected to it. If this occurs, 
perform one of the following methods to insert the wire.
• Change the direction of inserting the connector by 90°.
• Correct the shape of the ferrule with tools such as pliers.

• If the molded case circuit breaker is located in an upper area and the power supply is wired through
the duct at the bottom, keep a sufficient distance between the input wires and internal wires, or use
the metal tubing for wiring. If input and output cables are placed in the same duct, the noise immunity
will be impaired.
• Place the noise filter as close as possible to the opening of the control panel. Use the diagram below
to the left for wiring.
• The power cables must be twisted or tightly bundled.
• Wire the power and signal lines separately.

4-3-2  Selecting Connection Component
This section describes the criteria for selecting connection components that are required to improve
noise immunity.
Thoroughly understand the characteristics such as capacity, performance, and the range of application
of the connection components before you select them.
Consult the manufacturer for details of the parts.
Select a molded case circuit breaker based on the maximum input current and inrush current.
z Maximum input current
• The momentary maximum output of the Servo Drive is approximately three times as much as the
rated output, and the maximum output duration is three seconds. 
Therefore, select a molded case circuit breaker which can operate 10
seconds or more at 300% of
the rated current.
• Select a molded case circuit breaker with a rated current larger than the sum of the effective load 
current (when multiple Servo Drives are used). Refer to Main Circuit and Motor Connections on 
page 3-9 for the rated current of the power supply input for each motor.
• When you select a molded case circuit breaker, add the current consumption by other devices
such as the Controller.
z Inrush Current
• The following table shows the inrush current of the Servo Drives.
• The amount of inrush current that a low-speed type molded case circuit breaker can flow for 0.02 
seconds is approximately 10 times higher than the rated current.
• To turn ON the power supply for multiple Servo Drives simultaneously, select a molded case cir-
cuit breaker whose allowable current in 20 ms is larger than the sum of the inrush currents shown
in the following table.
• The inrush current of  the control power supply is limited by the output capacity of the DC power
supply in use.

The value of the inrush current varies depending on the input voltage to the Servo Drive. The values 
shown above are for the following input voltages.
• Select a leakage breaker which is made for high frequency and surge resistance.
• When you determine the threshold value for leakage current detection, add the total leakage current 
from all devices that are connected to the same breaker.
• Refer to the catalogs from the manufacturers for details on how to select a leakage breaker and
ensure a sufficient margin.

• Install surge suppressors for a load with an induction coil such as a relay, solenoid, and clutch.
• The following table gives the types of surge suppressors and the recommended products.
• The manufacturer of varistor is shown below. Refer to the catalogs from the manufacturer for details.
Varistor: SEMITEC Corporation, Panasonic Corporation
Select a contactor based on the inrush current that flows through circuits and the maximum momentary 
phase current.
For details on the inrush current of the Servo Drives, refer to Molded Case Circuit Breaker (MCCB) on 
page 4-39.
The I/O signals may malfunction if control I/O is affected by noise.
• Use the control I/O power supply (especially 24 VDC) which is completely separated from the exter-
nal power supply used for operation. Especially, be careful not to connect the ground wires of these
two power supplies.
• Install a noise filter on the primary side of the control I/O power supply.
• When you use a motor with a brake, do not share the 24 VDC power supply between the brake and
the control I/O (24 VDC). Also, do not connect the ground wires. Doing so may cause I/O signals to
malfunction.
• If there is a long wiring for the control I/O power supply, you can improve its noise immunity by adding 
an approximately 1-µF laminated ceramic capacitor between the control I/O power supply and the 
ground at the Servo Drive's input section or the Controller's output section.
Surge Suppressors
Type Feature Recommended product
Diode Diodes are used for relatively small loads 
such as relays when the reset time is not 
an issue.
The surge voltage at power cutoff is the 
lowest, but the reset time takes longer.
Used for 24/48-VDC systems.
Use a high-speed diode, especially the 
fast-recovery diode with short reverse 
recovery time such as RU2 made by San-
ken Electronic Co., Ltd.
Varistor Thyristors and varistors are used for 
loads when an induction coil is large, as in 
a solenoid, and when reset time is an 
issue.
The surge voltage at power cutoff is 
approximately 1.5 times the varistor volt-
age.
Select the varistor voltage according to 
the following list.
• 24-VDC type: varistor voltage 39 V
• 100-VDC type: varistor voltage 200 V
• 100-VAC type: varistor voltage 270 V
• 200-VAC type: varistor voltage 470 V
Capacitor and 
resistor
The combination of capacitor and resistor 
is used to absorb vibration in the surge at 
power cutoff. You can shorten the reset 
time by selecting the appropriate capaci-
tance and resistance.

4-4-1  Calculating the Regenerative Energy
4-4 Regenerative Energy Absorption
The Servo Drives have a built-in capacitor, which absorbs the regenerative energy produced during 
motor deceleration, etc. When the built-in capacitor cannot absorb all regenerative energy, the Internal 
Regeneration Resistor absorbs the rest of the energy. If the amount of regenerative energy from the 
Servomotor is too large, regeneration operation stops and an Overvoltage Error occurs in order to pre-
vent the Internal Regeneration Resistor from burning. 
If this occurs, reduce the regenerative energy by changing operating patterns, or increase the regener-
ation process capacity by connecting an External Regeneration Resistor.
Additional Information
• Some Servo Drive models do not have the Internal Regeneration Resistor.
• Regenerative energy absorption capacity depends on the Servo Drive model. 
Refer to Amount of Internal Regeneration Absorption in Servo Drives on page 4-48 for check-
ing the Servo Drive model with Internal Regeneration Resistor and its regenerative energy 
absorption capacity.
Regenerative energy calculation for a horizontal axis is explained.
• In the output torque graph, acceleration in the positive direction is shown as positive (+), and acceler-
ation in the negative direction is shown as negative (-).
• The regenerative energy values in each region can be calculated from the following equations.
Note Due to the loss from motor winding resistance and inverter, the actual regenerative energy will be approxi-
mately 90% of the values calculated from the above equations.

4-4-1  Calculating the Regenerative Energy
z Regenerative Energy Absorption by Built-in Capacitor
If both of the previously mentioned values Eg1 and Eg2 [J] are smaller than or equal to the amount 
of regenerative energy Ec [J] that the Servo Drive’s built-in capacitor can absorb, the built-in capaci-
tor can process all regenerative energy.
If either of Eg1 and Eg2 [J] is larger than the amount of regenerative energy Ec [J] that the Servo 
Drive’s built-in capacitor can absorb, use the following equation to calculate the average amount of 
regenerative power Pr [W].
Note If the result of (Eg1 - Ec) is zero or less, then assign 0 to the result. The same applies to the case where 
(E
g2 - Ec) is zero or less.
The above equation calculates the average regenerative power Pr [W] that cannot be absorbed by 
the built-in capacitor.
If this average regenerative power Pr [W] is smaller than or equal to the average regenerative power 
which the Servo Drive’s Internal Regeneration Resistor can absorb, the Servo Drive can process all 
regenerative energy.
If the Internal Regeneration Resistor cannot process the average regenerative power Pr [W], take 
the following measures.
• Connect an External Regeneration Resistor. Regenerative process capacity improves.
• Reduce the operating rotation speed. The amount of regenerative energy is proportional to the 
square of the rotation speed.
• Lengthen the deceleration time. Regenerative energy per unit time decreases.
• Lengthen the operation cycle, i.e., the cycle time. Average regenerative power decreases.

4-4-3  Regenerative Energy Absorption by an External Regeneration Resistance Device
If the regenerative power exceeds the average regenerative power that the Internal Regeneration 
Resistor of the Servo Drive can absorb, connect an External Regeneration Resistance Device.
Connect the External Regeneration Resistance Device between B1 and B2 terminals on the Servo 
Drive.
Double-check the terminal names when you connect the resistor because the Servo Drive may be dam-
aged if the resistor is connected to the wrong terminals.
The surface of the External Regeneration Resistance Device will heat up to approximately 200°C. Do 
not place it near equipment and wiring that is easily affected by heat. 
Refer to 3-5 Specifications of External Regeneration Resistors and External Regeneration Resistance 
Units on page 3-93 for details on the specifications.

4-5 Adjustment for Large Load Inertia
The applicable Servomotor load inertia is a value to prevent the Servo Drive circuits from damage 
during normal operation.
For the use of the Servomotor within the range of applicable load inertia, the precautions for adjustment 
and dynamic brake are described below.
Do not use the dynamic brake frequently for deceleration operation because the dynamic brake is 
intended for the stop at the time of an error.
Observe the following instructions to prevent wire breakage, smoking and ignition from occurring in the 
dynamic brake.
• Do not use Servo ON/OFF to start and stop the Servomotor when it is not necessary.
• Do not use an external drive source to drive the Servomotor. Do not turn ON the power supply during 
motor rotation.
• When the Servomotor is stopped by the dynamic brake, allow it to be in a stop state for three minutes 
or more before the Servo is turned ON again.
As a guide, the dynamic brake can be used 1,000 times under the following conditions:
Stopping is performed when the Servomotor rotates at the rated speed, the maximum applicable load 
inertia is not exceeded, and the dynamic brake is used once every three minutes.
The load applied to the dynamic brake circuit increases in proportion to the load inertia and rotation 
speed. An excessive load may cause a failure.
Use the following expression as a guide for determining the operating rotation speed and operating 
inertia.
Operating inertia ≤ (Maximum applicable inertia + Servomotor inertia) ×    - 
Servomotor inertia
Refer to 7-13 Dynamic Brake on page 7-45 for how to set the dynamic brake.

5-2 Structure of the CAN Application 
Protocol over EtherCAT
This section explains the structure of the CAN application protocol over EtherCAT (CoE) for a 1S-series 
Servo Drive with built-in EtherCAT communications.
Normally, EtherCAT can transmit different protocols. 1S-series Servo Drives with Built-in EtherCAT 
Communications use the IEC 61800-7 (CiA 402) drive profile.
The object dictionary in the application layer contains parameters and application data as well as infor-
mation on the PDO mapping between the process data servo interface and Servo Drive application.
The process data object (PDO) consists of the object dictionary that can be used for PDO mapping. 
The contents of the process data are defined by the PDO mapping.
Process data communications cyclically reads and writes the PDO. Mailbox communications (SDO) 
uses asynchronous message communications where all objects in the object dictionary can be read 
and written.

5-4 Process Data Objects (PDOs)
The process data objects (PDOs) are used for real-time data transfer during cyclic communications. 
PDOs can be RxPDOs, which receive data from the controller, or TxPDOs, which send status from the 
Servo Drive to the host controller.
The EtherCAT application layer can hold multiple objects to enable transferring Servo Drive process 
data. The contents of the process data are described in the PDO mapping objects and the Sync Man-
ager PDO Assignment objects.
The PDO mapping objects provide mapping for the application objects (real-time process data) 
between the object dictionary and PDOs.
The number of mapped objects is shown in subindex 00 hex in the mapping table. In this mapping 
table, 1600 to 17FF hex are for RxPDOs and 1A00 to 1BFF hex are for TxPDOs.
1S-series Servo Drives use 1600 hex, 1701 to 1705 hex, and 1710 hex for an RxPDO, and 1A00 hex, 
1B01 to 1B04 hex, 1B10 hex, and 1BFF hex for a TxPDO.

5-4-4  Variable PDO Mapping
1S-series Servo Drives allow you to change some mapped objects.
The PDO mapping objects for which you can change the setting are the 1st receive PDO Mapping 
(1600 hex) and the 1st transmit PDO Mapping (1A00 hex).
These objects can be changed only when the EtherCAT communications state is Pre-Operational 
(Pre-Op). Since the mapping you changed is not saved in non-volatile memory, set the EtherCAT mas-
ter so that the settings can be configured each time you turn ON the power supply in order to use the 
mapping other than the default setting.
Precautions for Correct Use
For information on the objects you can map, refer to A-2-5 PDO Mapping Objects on page

1S-series Servo Drives use Sync Manager 2 to 5 PDO Assignment.
You can assign PDO mapping objects to each Sync Manager as shown in the following table.
Objects are mapped in the order of subindex setting 01 hex, 02 hex, and 03 hex.
These objects can be changed only when the EtherCAT communications state is Pre-Operational 
(Pre-Op). Since the mapping you changed is not saved in non-volatile memory, set the EtherCAT mas-
ter so that the settings can be configured each time you turn ON the power supply in order to use the 
mapping other than the default setting.
Precautions for Correct Use
• If mapped objects exceed the maximum total size, the RxPDO Setting Error (Error No.90.05) 
or TxPDO Setting Error (Error No.90.06) occurs.
• If the same object is mapped in an RxPDO more than once, the value of the last object is 
used.
• If the same object is mapped in a TxPDO more than once, the values of the all objects are 
updated.

5-6 Synchronization Mode and Commu-
nications Cycle
1S-series Servo Drives support the following synchronization modes.
• Distributed Clock (DC) Mode
• Free-Run Mode
Note SM Event Mode is not supported.
A mechanism called distributed clock (DC) is used to synchronize EtherCAT communications.
The DC Mode is used for 1S-series Servo Drives to perform highly accurate control in a multi-axis sys-
tem.
In DC Mode, the master and slaves are synchronized by sharing the same clock.
Interruptions (Sync0) are generated in the slaves at precise intervals based on this clock.
Servo Drive control is executed at this precise timing.
The communications cycle is determined by setting the output cycle of Sync0 signal on the master side.
You can use the Free-Run Mode when synchronization such as the DC Mode is not required.
In Free-Run Mode, slaves perform I/O processing, i.e. refresh I/O data asynchronously with the com-
munications cycle of the master. 
The communications cycle is determined by the cycle time of the master.

5-7 Emergency Messages
When an error or warning occurs in a 1S-series Servo Drive, an emergency message is sent to the 
master through SDO communications. An emergency message is not sent for a communications error.
You can select whether or not to send emergency messages in Diagnosis History (10F3 hex).
When the power supply is turned ON, Diagnosis History – Flags (10F3-05 hex) is set to 0 (not 
notify).
To send emergency messages, set the least significant bit of Diagnosis History – Flags (10F3-05 hex) 
to 1 every time the power is turned ON.
An emergency message consists of 8-byte data.
Note For details on errors and warnings of the Servo Drive, refer to Section 12 Troubleshooting.

5-8 Sysmac Device Features
Sysmac Device refers to the control device product designed according to standardized communica-
tions and user interface specifications for OMRON control devices. And the features that are available 
with such a device are called Sysmac Device Features.
This section describes the features that the Servo Drive provides when it is combined with a Machine 
Automation Controller such as NJ/NX series and automation software.
Because, in Sysmac Devices, errors that may occur in slaves are systematized, you can check the 
causes and remedies for errors with a common procedure.
The status of an error can be monitored in the Sysmac Error Status (2002-01 hex). To display the 
error detected by the Servo Drive in Sysmac Studio, the Sysmac Error Status (2002-01 hex) must be 
mapped to the PDO. Sysmac Studio, by default, uses the 512th transmit PDO Mapping (1BFF hex) 
assignment to map the Sysmac Error Status (2002-01 hex) automatically to the PDO.
Additional Information
• For the Sysmac Error Status (2002-01 hex), refer to A-2-7 Manufacturer Specific Objects on 
page A-38.
• For errors displayed in Sysmac Studio, refer to A-4 Sysmac Error Status Codes on page 
A-98.

(3) The EtherCAT master reads the value that is set in Register: 0012 hex.
(4) The EtherCAT master writes the value of 0012 hex to 0010 hex as the node address.
The serial number saved in the non-volatile memory of the Servo Drive is displayed in the Serial Num-
ber (1018-04 hex). Controllers that support Sysmac Device Features can use this serial number to 
check the network configuration.
To enable this check, in Sysmac Studio, set Serial Number Check Method to Setting = Actual 
Device on the EtherCAT tab page.
If the specified condition is not met, a Network Configuration Verification Error will occur.
Additional Information
This network configuration check can detect the replacement of slave devices, which prevents 
you from forgetting to set parameters on those slaves.
The ESI Specification is a set of specifications that define the entries required in an EtherCAT Slave 
Information (ESI) file.
Controllers that support Sysmac Device Features can use the Option function defined in the ESI Speci-
fication to identify the backup parameters stored on slaves.
The backup parameters on an identified slave can be backed up and restored from Sysmac Studio.

The Slave Information Interface (SII) contains EtherCAT slave configuration information that is written 
to the non-volatile memory of an EtherCAT slave.
Sysmac Device EtherCAT slaves check the SII information from the slave side.
If one of these slaves finds that SII information with which it cannot operate was written, it generates an 
SII Verification Error (Error No. 88.03) or ESC Initialization Error (Error No. 88.01). If this error is not 
cleared after the power cycle, contact your OMRON sales representative.
Precautions for Correct Use
Do not use non-OMRON configuration tools to edit the SII information.

6-1-2  Control Method
For the 1S-series Servo Drives, TDF control and ODF control are available.
In the TDF control, you can adjust the servo rigidity against disturbance and the target path following 
performance separately.
Therefore, you can perform the adjustment to suppress overshooting without lowering servo rigidity.
In the ODF control, the offset can be input as you expect because there is no interruption due to 
feed-forward input from the TDF control section.
Use TDF control in normal operation. Use ODF control when Velocity offset and Torque offset are input 
from the host controller.

6-3 Cyclic Synchronous Position Mode
In this mode of operation, the controller has a path generation function (an operation profile calculation 
function) and it gives the target position to the Servo Drive in cyclic synchronization.
Velocity offset (60B1 hex) and Torque offset (60B2 hex) can be used as the velocity feed-forward 
and torque feed-forward amounts respectively.
The following diagram shows the configuration of the Cyclic synchronous position mode.

6-6 Profile Position Mode
In this mode of operation, the controller uses the path generation function (an operation profile calcula-
tion function) inside the Servo Drive to perform PTP positioning operation. It executes path generation 
based on the target position, profile velocity, profile acceleration, profile deceleration, and other infor-
mation.
The Profile position mode can be used when the communications period is 250 μs or more. If the com-
munications period is less than 250 μs, a Command Error (Error No. 91.01) occurs.
The following diagram shows the configuration of the path generation function.
To use these objects, map them in the variable PDO mapping as appropriate.

6-8 Homing Mode
In this mode of operation, the Servo Drive has a path generation function (an operation profile calcula-
tion function) and it executes the homing operation in the Homing method specified from the controller.
When a controller is connected, the following two homing procedures are available depending on the 
controller specifications.
Create a homing operation pattern in the controller, and provide the command to the Servo Drive in 
Cyclic synchronous position mode (csp).
When you use the controller to perform the homing operation in procedure 1, refer to the manual for the 
controller.
Use the Homing mode of the Servo Drive. The controller specifies a homing method supported by the 
Servo Drive and commands the start of the homing operation.
The Homing mode can be used when the communications period is 250 μs or more. If the communica-
tions period is less than 250 μs, a Command Error (Error No. 91.01) occurs.
When you use the controller to perform the homing operation in procedure 2, refer to the manual for the 
controller and A-1-5 Homing Mode Specifications on page A-7.
Additional Information
Procedure 1 is used for the OMRON Machine Automation Controller NJ/NX-series CPU Unit 
and the Position Control Unit (Model: CJ1W-NC8). In this procedure, the Position Control 
Unit creates a homing operation pattern and provides the command to the Servo Drive in the 
Cyclic synchronous position mode (csp) to perform the homing operation.

7-1 General-purpose Input Signals
The 1S-series Servo Drive provides 8 ports for general-purpose input signals to which you can allocate 
function inputs in the Control I/O Connector (CN1). You can also set the logic for input signals that can 
be allocated. Note that you cannot allocate more than one function to the same general-purpose input 
signal.
Refer to 3-1-5 Control I/O Connector (CN1) Specifications on page 3-14 for I/O signal connection and 
external signal processing.
General Input 7 (IN7) and 8 (IN8) are high-speed inputs. Use these inputs for functions that require high 
precision, such as the latch input.
Precautions for Correct Use
The signal status must be held for at least 125 μs for high-speed inputs and at least 2 ms for 
other inputs.

7-1-3  Function Input Details
This section explains the function inputs that can be allocated to the general-purpose inputs.
z Error Stop Input (ESTP)
• This signal is used to forcibly generate an error to stop motor rotation from an external device.
• If the Error Stop Input (ESTP) signal turns ON during motor rotation, the Servomotor stops 
according to the setting in the Stop Selection - Fault Reaction Option Code (3B20-04 hex).
• If the Error Stop Input (ESTP) signal turns ON when the Servomotor is energized, the Error Stop 
Input (Error No. 87.00) will occur.
z Positive Drive Prohibition Input (POT) and Negative Drive Prohibition Input 
(NOT)
• These two input signals prohibit the positive and negative drive (over-travel).
• When these terminals are short-circuited (default setting), the Servo Drive can drive the Servomo-
tor in each rotation direction.
• In the drive prohibition state, the Servo Drive does not enter an error state.
• To use this function, set Drive Prohibition - Enable (3B10-01 hex) to 1.
• When Drive Prohibition - Enable (3B10-01 hex) is set to 1, you can select the operation at a 
drive prohibition input in Drive Prohibition - Stop Selection (3B10-02 hex).
z Home Proximity Input (DEC)
• This is the deceleration signal for homing.
• If the Home Proximity Input turns ON while the Servomotor is running at the Speed During 
Search for Switch (3A00-03 hex), it will decelerate to Homing - Speed During Search for Zero 
(3A00-04 hex).
z External Latch Input (EXT1 and EXT2)
• These are the external input signals to latch the present position.
• The encoder position data is obtained at the rising edge when the External Latch Input is turned 
ON.
z Monitor Inputs (MON1 to MON8)
• These can be used as general-purpose monitor inputs.
• The general-purpose monitor inputs do not affect operation, and they can be monitored from the 
host controller.
z Positive Torque Limit Input (PCL) and Negative Torque Limit Input (NCL)
• The Positive Torque Limit Input (PCL) is used to switch the torque limit between the Positive 
torque limit value (60E0 hex or 3330-03 hex) and Positive Torque Limit Value 2 (3330-05 hex).
• The Negative Torque Limit Input (NCL) is used to switch the torque limit between the Negative 
torque limit value (60E1 hex or 3330-04 hex) and Negative Torque Limit Value 2 (3330-06 
hex).
•Use the Torque Limit - Switching Selection (3330-01 hex) to select a method to switch the 
torque limit.

If Drive Prohibition - Enable (3B10-01 hex) is set to 1 (Drive Prohibition Enabled), when the Servo 
Drive detects that the Positive Drive Prohibition Input (POT) or Negative Drive Prohibition Input (NOT) 
is active, it stops the Servomotor according to the method specified in Stop Selection (3B10-02 hex).
Precautions for Correct Use
• Because the deceleration stop causes the Servomotor to decelerate quickly, in the position 
control mode, the following error may become large momentarily. This results in an Exces-
sive Position Deviation Error (Error No. 24.00). If this error occurs, set the Position Detec-
tion Function - Following Error Window (3B50-05 hex) to an appropriate value.
• A load on the vertical axis and so forth may fall due to its own weight when the Drive Prohibi-
tion Input is ON. To prevent the load from falling, set Drive Prohibition - Stop Selection 
(3B10-02 hex) to 2 so that the Servomotor decelerates with the deceleration stop torque and 
stops with the servo lock, or use the host controller to limit the operation instead of this func-
tion.
• A Command Warning (Error No. B1.00) will occur if a command is given in the drive prohibi-
tion direction while the Servomotor is stopped (i.e., decreases the speed to approximately 30 
r/min or lower) and the Drive Prohibition Input is active.
• By default, drive prohibition disabled (drive prohibition does not operate) is set. Set Drive 
Prohibition - Enable (3B10-01 hex) to 1 (drive prohibition enabled) for a system that 
requires the drive prohibition input.
Additional Information
While the Positive Drive Prohibition Input (POT) is active, the Servomotor cannot be driven in 
the positive direction, but it can be driven in the negative direction. Conversely, while Negative 
Drive Prohibition Input (NOT) is active, the Servomotor cannot be driven in the negative direc-
tion, but it can be driven in the positive direction.

7-5-3  Description of Operation
When the first operation after Servo ON is performed in the direction specified in Backlash Compen-
sation Selection (3001-02 hex), position data is compensated by Backlash Compensation Amount. 
After that, compensation is executed each time the operation direction is reversed.
The compensation is performed for the target position and the present position. The software position 
limit function and the latch function are performed based on the position data after compensation.
Backlash Compensation is performed as follows:
To determine the actual position of the Servomotor, the Servomotor position data acquired via Ether-
CAT communications is offset by the Backlash Compensation Amount.
If the Servo is turned OFF when backlash compensation is performed, the position data is reset to the 
value that does not contain Backlash Compensation Amount. The backlash compensation is performed 
as described above when the Servo is turned ON again.
Additional Information
Conditions for Clearing Backlash Compensation
• When the following error is reset:
This includes when the Servo is OFF, and when following error is cleared due to the drive 
prohibition input.
• When the position data is initialized, except for the homing operation in Homing mode (hm):

Precautions for Correct Use
• The brake built into a Servomotor with a brake is a non-excitation brake designed only to hold 
the motor in the stop state when the operation is stopped. Accordingly, set an appropriate 
time so that the brake is applied after the Servomotor stops.
• If the brake is applied while the Servomotor is rotating, the brake disc will wear abnormally or 
sustain damage. This results in a bearing or encoder failure in the Servomotor.
• The workpiece may fall when the brake is released for a vertical axis. Carefully consider the 
timing of releasing the brake.

7-6-2  Operation Timing
Based on these operation timings, regenerative energy is produced if the motor rotation stops abnor-
mally. Accordingly, repeated operation cannot be performed. Provide a wait time of at least 10 minutes 
for the motor to cool down.
*1. The Servo does not turn ON until the motor rotation speed drops to 30 r/min or lower. If the Servo ON com-
mand is input during motor rotation, the Command Warning (Error No. B1.00) will occur. The Servo ON com-
mand is ignored.
*2. The operation of the dynamic brake when the Servo is OFF depends on the set value in Stop Selection – 
Disable Operation Option Code (3B20-02 hex).
*3. The Brake Interlock Output (BKIR) signal is output when a release request command is received from either 
servo control or EtherCAT communications. The above example shows when there is no brake release 
request from EtherCAT communications.
*4. “t1” is the period until the value becomes smaller than the set value in the Timeout at Servo OFF (4610-02 
hex) or the Threshold Speed at Servo OFF (4610-03 hex), whichever comes earlier.
*5. Depends on the set value in Brake Interlock Output – Hardware Delay Time (4610-04 hex).
Note 1. Even when the Servo ON input is turned ON again while the motor is decelerating, the system does not 
enter the Servo ON state until the motor stops.
2. If the Brake Interlock Output (BKIR) is output because of Timeout at Servo OFF (4610-02 hex), a Brake 
Interlock Error (Error No. 97.00) will occur.

Note 1. Even when the Servo ON input is turned ON again while the motor is decelerating, the system does not 
enter the Servo ON state until the motor stops.
2. If the main circuit power supply turns OFF while the motor is operating, a phase loss error or main circuit

7-7 Electronic Gear Function
The Electronic Gear Function controls the position by using the value that is obtained by multiplication 
of the position command input from the host controller by the specified gear ratio.
The Electronic Gear Function can be used when the communications period is 250 µs or more. When 
the communications period is 125 µs, set the gear ratio to 1:1.
When the Servo Drive is connected to an OMRON Machine Automation Controller NJ/NX-series CPU 
Unit, the electronic gear ratio is set on the controller. Set the electronic gear ratio to 1:1 on the Servo 
Drive.
Note If the unit version of the NJ/NX-series CPU Units is 1.10 or ealier, some Servomotors cannot be driven at 
the maximum rotation speed. In such a case, set the electronig gear ratio of the Servo Drive to 2:1 or 
higher.
When the Servo Drive is connected to an OMRON Position Control Unit (Model: CJ1W-NC8), set 
the electronic gear ratio to 8:1 or higher on the Servo Drive.
Precautions for Correct Use
To make the position command smoother after the electronic gear setting, adjust it by using the 
Position Command Filter (3011 hex).

7-9 Soft Start 
This function performs auto acceleration and deceleration inside the Servo Drive when step-type veloc-
ity commands are input.
To reduce any impacts made by acceleration changes, you can also use the velocity command 
first-order lag filter.
For a step velocity command input, set the time required for the velocity command to reach 1,000 r/min 
in Acceleration Time.
Similarly, set the time required for the velocity command to decrease the velocity from 1,000 r/min to 0 
r/min in Deceleration Time.
Acceleration Time [ms] = Vc/1,000 r/min × Acceleration Time × 0.1 ms

The Mode Selection is used to set the condition to switch between Gain 1 and Gain 2.
When you select Gain 1, control is performed based on 1st Position Control Gain, 1st Velocity Con-
trol Gain, and 1st Torque Command Filter. When you select Gain 2, control is performed based on 
2nd Position Control Gain, 2nd Velocity Control Gain, and 2nd Torque Command Filter.
The following is an operation example.
Mode Selection: 
Gain Switching in Position Control - Mode Selection (3212-01 hex) = 0: Gain1
Gain Switching in Velocity Control - Switching Selection (3222-01 hex) = 1: Gain 2

If Mode Selection is set to 1, 2st Position Control Gain (3214 hex), 2st Velocity Control Gain (3224 
hex), and 2st Torque Command Filter (3234 hex) are used.
If Mode Selection is set to 2, you can switch between Gain 1 and Gain 2 by changing the value of bit

7-10-3  Gain Switching in Position Control
If Mode Selection is set to 3, you can switch between Gain 1 and Gain 2 by using the position com-
mand and the motor velocity.
Set the Gain Switching in Position Control - Speed (3212-03 hex) to a speed threshold to switch 
from Gain 2 to Gain 1. You can set the delay time for this switching operation in Delay Time (3212-02 
hex).
Gain 1 switches to Gain 2 when the position command velocity becomes a value other than 0.
After the operation is performed, the position command velocity becomes 0, and Gain 2 switches to 
Gain 1 when the motor velocity reaches the set Gain Switching in Position Control – Speed 
(3212-03 hex) or lower and the Gain Switching in Position Control – Delay Time (3212-02 hex) 
elapses.
After Gain 2 switched to Gain 1, the Gain 1 is held even if overshooting occurs and the motor velocity 
exceeds the Gain Switching in Position Control - Speed (3212-03 hex).
In position control, vibration may occur if Gain 1 and Gain 2 are switched and the gain increases rap-
idly. To switch the gain gradually and suppress the vibration, set Position Gain Switching - Time 
(3212-04 hex).
When the gain changes from a lower set value to a higher set value, it increases in the specified time. 
When the gain changes to a lower value, the change occurs immediately.

8-1 Safe Torque OFF Function
The Safe Torque OFF (STO) function is used to cut off the motor current and stop the motor through the 
input signals from a safety controller.
When the STO function is activated, the Servo Drive turns OFF the Servo Ready Output (READY) and 
enters the safe state.
The 1S-series Servo Drives have the following two types of STO functions. Use either of these func-
tions according to your safety device configuration.
• STO function via safety input signals
• STO function via EtherCAT communications
The PFH value of the 1S-series Servo Drives is as follows.
Precautions for Correct Use
On setting
• Before you execute downloads and restoration, check that the equipment does not operate.
• When downloads and restoration are completed, conduct the user test before system opera-
tion to make sure that all safety devices operate correctly.
On replacement
• A Servo Drive before replacement must have the factory default condition. If you are not sure 
that the Servo Drive has the factory default condition, initialize the parameters for the Servo 
Drive after replacement.
• When you replace a unit, make sure that the unit model is correct, the mounting positions of 
the unit and terminal blocks are correct, and the unit is properly configured and operates as 
intended.
On conducting test run
• When you use Sysmac Studio to perform a test run without EtherCAT cable connection, the 
STO function via EtherCAT communications is disabled temporarily. If you need the STO 
function during this type of test run, use the STO function via safety input signals.
On use of STO function
• When you use the STO function, be sure to execute a risk assessment of the equipment to 
confirm that the system safety requirements are met.
• There are the following risks even when the STO function is operating. Be sure to take safety 
into account as part of the risk assessment.
• The motor runs if an external force is present (e.g., force of gravity on a vertical axis). If 
holding is required, implement appropriate measures, such as providing external brakes. 
The brakes for a Servomotor with brakes are used for holding only, and cannot be used for 
control.
• Even if there is no external force, when Stop Selection - Shutdown Option Code 
(3B20-01 hex) is set to free-run with the dynamic brake disabled, the motor uses free-run 
stopping and the stop distance is long.
• In case of internal failure of components such as the power transistor, the motor may oper-
ate in the range of up to 180 degrees of electrical angle.
• The power supply to the motor is cut off by the STO function, but the power supply to the 
Servo Drive will not be cut off nor electrically isolated. When you conduct Servo Drive 
maintenance, cut off the power supply to the Servo Drive through another means.

• The EDM output signal is not a safety output. Do not use the EDM output for any purpose 
other than the failure monitoring function.
• During installation, be sure to perform wiring check. Especially, check the following items.
• There is no short circuit nor disconnection
• The EDM circuit polarity is correct (not reversed)
• SF1, SF2, and EDM operate correctly
• Wrong wiring may prevent the safety function from operating correctly.
• The dynamic brake and the external brake release signal output do not belong to the 
safety-related parts. During the system design, make sure that there is no danger even if the 
external brake release function fails in the STO status.
• When you use the STO function, connect equipment that meets the safety standards.
• When you use the STO function with the safety input signals wired, confirm STO operation 
once every three months.
• When you use the STO function via EtherCAT communications, be sure to turn the power 
from OFF to ON once every three months to check that no error occurs due to the 1S-series 
Servo Drive’s self diagnosis (at power ON).
• Before you build a system with the safety function, make sure that you thoroughly understand 
the related safety standards and specifications in the user’s manuals so that you can design 
a system that meets all requirements of those standards and specifications.
• Qualified engineers must develop your safety-related system and install safety products in 
devices and equipment. Prior to machine commissioning, verify through testing that the 
safety products work as expected.
• Carefully read the specifications and precautions as well as all items in the Instruction Man-
ual for your safety product to learn appropriate usage procedures. Any deviation from instruc-
tions will lead to unexpected device or equipment failure not anticipated by the safety-related 
system.
• Conduct the user test before system operation to make sure that all safety devices operate 
correctly. Otherwise, safety functions may be impaired and serious injury may result.
• Design programs for the safety controller so that the STO function is not canceled automati-
cally even when the emergency stop switch is released.
• Design programs for the safety controller so that the STO function is not canceled automati-
cally when a Servo Drive failure is detected through the EDM output.
• When you use the STO function via EtherCAT communications, enable the security function 
of the EtherCAT master to ensure that the PDO mapping is not changed.
• Use the Operation Authority Verification function in the NJ/NX-series CPU Unit to enable the 
security function. Set authorities so that synchronization of the transfer operations cannot be 
operated. Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for 
details.

8-2 STO Function via Safety Input Signals
This section explains how to use the STO function via the safety input signals.
The following I/O signals are available to use the STO function: the safety input signals (SF1 and SF2) 
and the external device monitoring (EDM) output signal.
Refer to
3-1-5 Control I/O Connector (CN1) Specifications on page 3-14 for I/O signal connection and 
external signal processing.
Two safety input circuits are installed to operate the STO function.
• When safety input 1 or 2 turns OFF, the STO function will start operating within 5 ms after the input, 
and the motor output torque will be cut off.
• Connect the equipment so that the safety input circuit turns OFF when the STO function is activated.
• Set the operation when the safety input turns OFF in the Stop Selection – Shutdown Option Code 
(3B20-01 hex).
Precautions for Correct Use
L pulses for self-diagnosis of safety equipment
When you connect a safety device, such as a safety controller or a safety sensor, the safety 
output signal of the device may include L pulses for self-diagnosis. To avoid malfunction due to 
the L pulses for self-diagnosis, a filter that removes the L pulses is built into the safety input cir-
cuit. If the OFF time of the safety input signal is 1 ms or less, the safety input circuit does not 
recognize it as OFF. To make sure that OFF is recognized, maintain the OFF status of safety 
input signal for at least 5 ms.

8-2-1  I/O Signal Specifications
This is a monitor output signal that is used to monitor the status of safety input signals from an external 
device.
Connect the EDM output signal to the external device monitoring terminal on a safety device, such as a 
safety controller or a safety sensor.
z Relationship between Safety Input Signals and EDM Output Signal
Normally when both safety inputs 1 and 2 are OFF, the EDM output circuit signal is ON. When both 
safety inputs 1 and 2 are OFF, this means the STO function is active in both 1 and 2 safety input 
circuits.
You can detect a failure of the safety input circuit and the EDM output circuit by monitoring all of the 
following 4 signal status from an external device.
These are the two cases of errors:
• Both safety inputs 1 and 2 are OFF, but the EDM output circuit signal does not turn ON.
• Either or both safety inputs 1 and 2 are ON, but the EDM output circuit signal is ON.
The maximum delay time is 6 ms after the safety input signal is input until the EDM output signal is 
output.
z Relationship between EtherCAT and EDM Output Signal
When a 1S-series Servo Drive is not connected to the EtherCAT network, its safe state is held by 
the STO function. The EDM signal is ON while in this state.
Precautions for Correct Use
Start the applications of the safety controller after the Servo Drive established EtherCAT com-
munications. If this condition is not met, an EDM error may be detected.

1 Add Safety PDOs to the 1S-series Servo Drive PDOs in the EtherCAT network configuration.
• RxPDO: 273th receive PDO Mapping (1710 hex)
• TxPDO: 273th transmit PDO Mapping (1B10 hex)
2 Enable the 1S-series Servo Drive in the setting for the Safety CPU Unit.
3 Use the following data and create safety programs for the Safety CPU Unit.
4 Establish communications between the EtherCAT master and the Safety CPU Unit.
The STO function is enabled when communications with the Safety CPU Unit are established 
once.
If the communications cannot be established after you change the Safety CPU Unit setting, 
clear the FSoE slave address.
Precautions for Correct Use
• When you use the STO function via EtherCAT communications, enable the security function 
of the EtherCAT master so that the PDO mapping is not changed.
• Use the Operation Authority Verification function in the NJ/NX-series CPU Unit to enable the 
security function. Set authorities  so that synchronization of the transfer operations cannot be 
operated. Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for 
details.
• When communications with the EtherCAT master are established, the STO status is detected 
and the 7-segment LED display shows “ST”. Reset STO after communications with the 
Safety CPU Unit are established.

For 1S-series Servo Drives, a special object called “mirror object” is defined.
A mirror object enables access to the same object from different object numbers. Accessing the mirror 
object and accessing the original object cause the same operation.
More specifically, the mirror objects are used to assign the Servo Drive profile objects (index number 
6000s) to the servo parameter objects (index number 3000s to 4000s).

occurs. If an error that causes the deceleration stop occurs, the deceleration stop is per-
formed according to the setting of Operation A. If an error that does not cause the decelera-
tion stop occurs, the dynamic brake operation or free-run is performed according to the 
setting of Operation B. For details on errors, refer to 12-3 Errors on page 12-10.

Sets the runaway detection function.
This object is available for the unit version 1.1 or later.
• Selects whether to enable or disable the runaway detection function.
z Description of Set Values
• The default value is 1 (enabled).
• When the runaway detection function detects that the Servomotor rotates in the opposite direction 
due to incorrect wiring of the motor cable, etc., a Runaway Detected (Error No. 20.00) occurs.
• When the command torque and the motor speed exceed a certain value after Servo ON, this func-
tion detects whether it is normal operation or an error. When the acceleration direction of the Ser-
vomotor does not conform to the direction of the command torque for a certain period of time, this 
function determines that the Servomotor rotates in the opposite direction, a Runaway Detected 
occurs.
Precautions for Correct Use
• If the gain is lower than the default setting, the runaway detection function may not work.
• If 1st Torque Command Filter - 
Cutoff Frequency (3233-02 hex) or 2nd Torque Command 
Filter - Cutoff Frequency (3234-02 hex) is set to 10 [Hz] or lower, this function may not 
work.
• When the Servomotor has a near-no load such that the inertia ratio is 50% or lower, if 1st 
Velocity Control Gain - Proportional Gain (3323-01 hex) or 
2nd Velocity Control Gain - 
Proportional Gain (3324-01 hex) is set to a value higher than 400 [Hz], this function may not 
work.
• If the Servomotor rotates in the opposite direction by an external force over the momentary 
maximum torque of the Servomotor.

z Description of Set Values
• Selects whether to estimate load characteristics and update a value of the dynamic friction compen-
sation.
z Description of Set Values
• Sets the value to adjust the amount of torque compensation which is calculated from the estimated 
viscous friction value. When the viscous friction coefficient update is enabled, the viscous friction 
coefficient is updated with a value which is calculated by multiplying the estimated viscous friction by 
this tuning coefficient.
• Viscous friction coefficient used in torque compensation = Estimated viscous friction coefficient × 
Tuning coefficient ÷ 100
• Selects the sensitivity to estimate load characteristics from load changes during the load characteris-
tic estimation.
• The higher the set value is, the earlier the load characteristic change is followed, but the estimated 
variation against the disturbance becomes greater.

• Gives the regenerative load ratio.
Sets the main circuit power supply.
• When the main circuit power supply is cut off for the time or more set in the Momentary Hold Time, it 
is recognized as the cutoff of the main circuit power supply and the PDS state transitions to Switch on 
disabled.
Precautions for Correct Use
When a single-phase power supply is used, the duration of undervoltage for the main circuit 
power supply may be several milliseconds longer than the actual interruption time, depending 
on the timing or phase at which a momentary power interruption occurs. To avoid false detec-
tion, set a value which is approximately five milliseconds longer than the interruption time.
• Selects whether to enable or disable the phase loss detection function for the 3-phase power supply.
• The model for both single- and/3-phase power supply operates according to the setting.
• This function does not work for the model for the single-phase power supply.

9-14-6  4610 hex: Brake Interlock Output
Sets the brake interlock operation. Refer to 7-6 Brake Interlock on page 7-22 for details.
• Set whether to enable or disable the brake interlock output.
• If this object is set to 0 (disabled), the Brake Interlock Output (BKIR) is turned ON (brake is released).
• If this object is set to 1 (enabled), the Brake Interlock Output (BKIR) is turned ON (brake is released) 
and OFF (brake is held) according to the Servo ON or Servo OFF state.
z Description of Set Values
• Sets the time from when the OFF state of the operation command is detected (the power supply to 
the motor is OFF) until the Brake Interlock Output (BKIR) is turned OFF (brake is held), when the 
Servo OFF is performed during motor operation.
• When the Servo OFF is applied during motor operation, the motor decelerates to reduce rotation 
speed. The Brake Interlock Output (BKIR) is turned OFF (brake is held) after the set time elapses.
• During operation, the set value of Threshold Speed at Servo OFF may be detected earlier, and this 
may cause the Brake Interlock Output (BKIR) to turn OFF (brake is held).
• If the Brake Interlock Output (BKIR) is turned OFF (brake is held) because the set value of Timeout 
at Servo OFF is detected, a Brake Interlock Error (Error No. 97.00) will occur.
• Sets the motor speed at which the Brake Interlock Output (BKIR) can be turned OFF (brake is held) 
after the Servo OFF command is detected, when the Servo OFF is performed during motor opera-
tion.
• During operation, the set value of Timeout at Servo OFF may be detected earlier, and this may 
cause the Brake Interlock Output (BKIR) to turn OFF (brake is held).

• The main circuit power supply inputs (L1/L2/L3) must be properly connected to the terminal block.
• The control circuit power supply inputs (24V,   or +24 V, 0V) must be properly connected to the ter-
minal block.
• The motor’s red (U), write (V), and blue (W) power lines and the green ( ) must be properly con-
nected to the terminal block.
• There should be no load on the Servomotor. Do not connect mechanical systems.
• The Servomotor side power lines and the power cables must be securely connected.
• The encoder cable must be securely connected to the encoder connector (CN2) at the Servo Drive.
• The encoder cable must be securely connected to the encoder connector of the Servomotor.

Do not connect the EtherCAT Communications Cables to the EtherCAT Communications Connectors 
(ECAT IN and ECAT OUT).
Make sure that the node address is correctly set on the ID switches.
Precautions for Correct Use
The ID switch setting is read only once when the Unit power supply is turned ON. Although the 
setting is changed after the Unit power supply is ON, it is not reflected in the control. It is 
enabled the next time the Unit power supply is turned ON. 
Turn ON the control circuit power after you finish the checks which you must conduct before turning ON 
the power supply. You can turn ON the main circuit power, but it is not a required.

the torque compensation is set, the axes move because the compensation command is out-
put when the Servo is turned ON.
• When you perform a test run via USB communications, pull out the EtherCAT cable before 
you turn ON the power supply to the Servo Drive.
• When you perform a test run from the Sysmac Studio without EtherCAT connection, you can-
not use the STO function via EtherCAT communications. If you need the STO function, use 
the STO function via safety input signals. In this case, display the test run pane so that you 
can reset STO status via safety input signals.
• If you need EtherCAT connection while you perform a test run from the Sysmac Studio with-
out EtherCAT connection, first terminate the test run function and then perform EtherCAT 
connection.
Additional Information
When you use an NJ/NX-series CPU Unit, you can perform a test run from the Sysmac Studio 
via EtherCAT. In this case, you can use the STO function via EtherCAT communications.

11-1-2  Adjustment Procedure
The natural vibration (resonance) of mechanical systems has a large impact on the gain adjustment of 
the Servo. The servo system responsiveness cannot be set high for machines with a low resonance fre-
quency (low machine rigidity).
To improve machine rigidity:
• Install the machine on a secure base so that it does not have any play.
• Use couplings that have a high rigidity, and that are designed for servo systems.
• When you use a timing belt, select a wide one. Use a tension within the range of allowable axial load 
for the Servomotor or decelerator output.
• When you use gears, select ones with small backlash.

11-7 Damping Control
If the tip of the mechanical unit vibrates, you can use the damping control function to reduce vibration.
This is effective on vibration generated by a low-rigidity machine. The applicable frequencies are from 
0.5 to 300 Hz.
Two damping filters, the Damping Filter 1 and 2, are provided to control two vibration frequencies simul-
taneously. Up to four damping frequencies can be set for each damping filter. This enables you to 
switch the damping frequency from one to another when it varies depending on the position.
Precautions for Correct Use
If you change the operation mode while damping control is used, stop the Servomotor before 
you change the mode. Changing the operation mode during motor operation may result in 
unexpected operation.

1 Adjust the position loop gain and the velocity loop gain.
In the easy tuning, manual tuning, advanced tuning, etc., Adjust 1st Position Control Gain or 
2nd Position Control Gain (1st: 3213 hex, 2nd: 3214 hex), 1st Velocity Control Gain or 2nd 
Velocity Control Gain (1st: 3223 hex, 2nd: 3224 hex), and 1st Torque Command Filter or 
2nd Torque Command Filter (1st: 3233 hex, 2nd: 3234 hex).
2 Measure the vibration frequency at the tip of the mechanical unit.
Measure the vibration frequency by using a device such as a laser displacement meter, servo 
accelerometer, and acceleration pick-up. 
Set the measured vibration frequency in one of 1st to 4th Frequency (01 hex, 03 hex, 05 hex, 
07 hex) of Damping Filter 1 or 2 (1: 3013 hex, 2: 3014 hex). Also set Damping Filter 1 Selec-
tion (01 hex) or Damping Filter 2 Selection (02 hex) of Damping Control (3012 hex) so that 
the frequency set in the above step is enabled.
If the frequency is set in 1st Frequency (01 hex) of Damping Filter 1 (3013 hex), set Damping 
Filter 1 Selection (01 hex) of Damping Control (3012 hex) to 1.
If vibration persists after you set the frequency, increase or decrease the damping frequency to 
find a proper frequency at which vibration decreases.
3 Make the damping filter settings.
Set the corresponding damping time coefficient of Damping Filter 1 or Damping Filter 2 (1: 
3013 hex, 2: 3014 hex). 
First, set it to 100% and check the torque waveform during operation. Setting a value smaller 
than 100% for the damping time can shorten the vibration suppression time, but it increases the 
maximum operation speed and torque command. Set the damping time within a range in which 
the maximum motor velocity is not exceeded and torque saturation does not occur. The effects 
of vibration suppression will be lost if the maximum motor velocity is exceeded or torque satura-
tion occurs.
Also, setting a large value for the damping time can reduce the torque command while the set-
ting time gets long.
4 Set Damping Control (3012 hex).
You can switch Damping filter 1 and 2 according to the conditions of the machine vibration.

11-8 Load Characteristic Estimation
The Load Characteristic Estimation function estimates the load characteristics of the machine in 
realtime, and sets values of the inertia ratio, viscous friction coefficient, unbalanced load compensation, 
and dynamic friction compensation automatically according to the result of estimation.
You can check the values that are set automatically with Machine – Inertia Ratio Display (3001-81 
hex), Torque Compensation – Viscous Friction Coefficient Display (3310-81 hex), Unbalanced 
Load Compensation Display (3310-82 hex), and Dynamic Friction Compensation Display 
(3310-83 hex and 3310-84 hex).
This Load Characteristic Estimation function is enabled in the position control, velocity control, and 
torque control.
Precautions for Correct Use
• The Load Characteristic Estimation function may not operate properly under the following 
conditions. In such cases, set the related objects manually.
Conditions that interfere with the Load Characteristic Estimation function
Load inertia • If the load inertia is small, i.e. less than 3 times the rotor inertia or large, i.e. the 
applicable load inertia or more
• If the load inertia changes easily
Load • If the machine rigidity is extremely low 
• If there is a non-linear element (play), such as a backlash
Operation  • If the speed continues at lower than 100 r/min
• If the acceleration/deceleration is 2,000 r/min/s or lower
• If the acceleration/deceleration torque is small compared with the unbalanced load 
and the friction torque
• If the speed or torque oscillates due to the high gain or small effect of each filter.

Precautions for Correct Use
• If the value that is set in the Inertia Ratio (3001-01 hex) is extremely different from the load 
inertia, operation may be unstable. In such a case, during this function operation, noise, 
vibration, velocity over the command, or overshooting may occur until the load inertia 
estimation is completed.
• If the unusual noise or vibration continues, take the following measures in the possible order.
• Write the objects that you used during normal operation to the non-volatile memory.
• Lower the gain.
• Manually set the notch filter.
• If unusual noise or vibration occurs, the setting of the inertia ratio or friction torque 
compensation may be changed to an extreme value. In such a case, check the values of 
Machine – Inertia Ratio Display (3001-81 hex), Torque Compensation – Viscous Fric-

Precautions for Correct Use
• After startup, immediately after the first servo ON, unusual noise or vibration may occur until 
the adaptive notch filter stabilizes. This is not an error if it disappears right away. If the 
vibration or unusual noise, however, continues for three or more reciprocating operations, 
take the following measures in the possible order.
• Write the value that are used during normal operation to the notch filter, and save the value 
in the non-volatile memory.
• Disable the adaptive notch filter by setting Adaptive Notch Selection (3320-01 hex) to 0. 
• Manually set the notch filter.
• If unusual noise or vibration occurs, the setting of the notch filter selected in Adaptive Notch

11-10 Notch Filters
A notch filter reduces a specified frequency component.
When the machine rigidity is low, factors such as axis torsion may produce resonance which results in 
vibration and noise. Thus you may not be able to set a high gain. The notch filter suppresses the 
resonance peak to reduce vibration and noise, and allows you to set a high gain.
The 1S-series Servo Drives provide four notch filters for which you can adjust each frequency, width 
and depth.
If mechanical resonance occurs, use this notch filter to eliminate resonance.

Function
You can set the following three types of friction torque compensations to reduce the influence of 
mechanical frictions.
• Unbalanced load compensation: Offsets the constantly applied unbalance torque
• Dynamic friction compensation: Compensates friction that changes its direction in accordance with 
the operating direction.
• Viscous friction compensation: Compensates friction that varies in accordance with velocity.
The friction torque compensation function is enabled under the following conditions.
• Position control or velocity control
• The Servo is ON.
The following table shows the relationship between the control method and enabled compensation 
functions.
The friction torque compensation function needs the combined settings of the following four objects.

11-11-3  Operation Example
The friction torque compensation is applied according to the operation as shown in the drawing below.
Note The dynamic friction compensation holds the compensation value until the command direction changes, in 
order to sustain the position during stabilization.
By setting the torque command value in Unbalanced Load Compensation (3310-02 hex), you can 
reduce the variations of positioning operations that occur depending on the movement directions. This 
object is useful when a constant amount of unbalanced load torque is always applied to the Servomotor 
at axes such as a vertical axis.
By setting the friction torque for each rotation direction in Positive Dynamic Friction Compensation 
(3310-03 hex) and Negative Dynamic Friction Compensation (3310-04 hex), you can reduce deteri-
oration of and inconsistencies in the positioning stabilization time due to dynamic friction. These objects 
are useful for loads that require a larger amount of dynamic friction torque for a radial load, such as the 
belt-driven shaft.

In the TDF control, the smooth internal commands are generated in the TDF control section so that 
rapid changes in target position or velocity do not cause overshooting. However, the smoother the 
internal commands are, the longer the delay of the internal commands gets. This trade-off between the 
overshooting suppression and internal command delay is adjusted with the command following gain.
The smaller the set value of Command Following Gain is, the more the overshooting can be 
suppressed.
Normally, set Command Following Gain to 50%. Set a value of approximately 30% when you want to 
suppress overshooting.

11-12-2  Feed-forward Control in ODF Control
The feed-forward function that can be used in the ODF control comes in 2 types: velocity feed-forward 
and torque feed-forward. In the ODF control, the responsiveness can be increased by changing these 
feed-forward amounts.
The following are the feed-forward setting objects used in the ODF control.
Increase the value of ODF Velocity Feed-forward – Gain (3112-01 hex) little by little to adjust the gain 
so that overshooting does not occur during acceleration/deceleration.
If you set ODF Velocity Feed-forward - Gain to 1,000 (100%), the calculated following error will be 0. 
However, large overshooting may occur during acceleration/deceleration.
The following error in a constant velocity range gets smaller as you increase the velocity feed-forward 
gain.

Set the inertia ratio as accurate as possible.
• If the inertia ratio is calculated when the Servomotor is selected, input the calculated value.
• If the inertia ratio is unknown, use the load characteristic estimation or easy tuning function to 
set the inertia ratio.
2 Adjust ODF Torque Feed-forward - Gain (3113-01 hex).
Increase value of ODF Torque Feed-forward - Gain (3113-01 hex) little by little.
Since the following error during constant acceleration/deceleration can be close to 0, it can be 
controlled almost to 0 throughout the entire operation range in a trapezoidal velocity pattern 
under ideal condition where no disturbance torque is applied.
In reality, disturbance torque is always applied and, therefore, the following error cannot be 
completely 0.
You can reduce the following error in a constant acceleration range by using the torque feed-for-

12-1 Actions for Problems
If any problems should occur, take the following actions.
This section explains the preliminary checks required to determine the cause of a problem if one 
occurs.
Check the voltage at the power supply input terminals.
Make sure that the power supply voltage for control input signals is within the range of 12 VDC-5% to 
24 VDC+5%, and the power supply voltage for safety input signals is within the range of 24 VDC±5%.
If the voltage is out of this range, operation failure may result. Be sure that the power supply is within 
the specified range.
Check whether an error exists by the use of the 7-segment LED display on the front of the Servo Drive 
or from the Sysmac Studio.
z When an Error Exists
Check the error display () and make an analysis based on the error that is indicated.
Refer to 12-5-1 Troubleshooting Using Error Displays on page 12-14.

12-1-2  Precautions When a Problem Occurs
The following figure shows the 7-segment display when an error exists.
Numbers from 0 to F hex are displayed as follows.
When you check and verify I/O after a problem occurred, the Servo Drive may suddenly start to operate 
or suddenly stop, so always take the following precautions.
You should assume that anything not described in this manual is not possible with this product.
• Disconnect the wiring before checking for cable breakage. If you test conduction with the cable con-
nected, test results may not be accurate due to conduction via bypassing circuit.
• If the encoder signal is lost, the Servomotor may run away, or an error may occur. Be sure to discon-
nect the Servomotor from mechanical systems before you check the encoder signal.
• When you perform tests, first check that there are no persons in the vicinity of the equipment, and 
that the equipment will not be damaged even if the Servomotor runs away. 
Before you perform the tests, verify that you can immediately stop the machine by the use of func-
tions such as the immediate stop in case the machine runs out of control.

12-3 Errors
If the Servo Drive detects an abnormality, it outputs an error (/ERR), turns OFF the power drive circuit, 
and displays the error number (main and sub) on the front panel.
Precautions for Correct Use
• Refer to 12-5-1 Troubleshooting Using Error Displays on page 12-14 for information on trou-
bleshooting.
• You can reset the error by turning OFF the power supply and then ON again, or executing the 
error reset command via EtherCAT communications or on the Sysmac Studio. Be sure to 
remove the cause of the error first.
• Some errors are reset only by turning the power supply OFF then ON again. For details, refer 
to
12-3-1 Error List on page 12-10.
• If nothing is displayed on the 7-segment display even when the control power supply is ON, it 
indicates that the internal MPU is malfunctioning. If you find this symptom, cut off the power 
supply immediately.

measures as shown below.
• For the error occurrence, check its frequency, timing, and the environment in which the error 
occurred.
• You can reduce errors that occur temporarily by taking noise countermeasures such as wiring a thick 
ground wire as short as possible.
• For details on noise countermeasures, refer to 4-3 Wiring Conforming to EMC Directives on page

lower, set the correct damping 
frequency for the damping filter 
to eliminate the vibration.
Vibration occurs due to 
machine resonance.
Check to see if the resonance 
frequency is high or low.
If the resonance frequency is

fied length.
Check the length of the 
encoder cable.
Shorten the encoder cable to 
less than 50 m.
Noise is entering into the signal 
lines because the encoder 
cable is stuck or the sheath is 
damaged.
Check the encoder cable for 
damage.
Correct the encoder cable’s 
pathway.
Excessive noise on encoder 
cable.
Check to see if the encoder 
cable is bound together with or 
too close to high-current lines.
Install the encoder cable where 
it won’t be subjected to surges.
The FG’s potential is fluctuating 
due to devices near the Servo-
motor, such as welding 
machines.
Check for ground problems 
(loss of ground or incomplete 
ground) at equipment such as 
welding machines near the Ser-
vomotor.
Ground the equipment prop-
erly and prevent current from 
flowing to the encoder FG.
Errors are caused by excessive 
vibration or shock on the 
encoder.
There are problems with

13-1 Periodic Maintenance
Servomotors and Servo Drives contain many components and will operate properly only when each of 
the individual components is operating properly.
Some of the electrical and mechanical components require maintenance depending on application con-
ditions. Periodic inspection and replacement are necessary to ensure proper long-term operation of 
Servomotors and Servo Drives. (Quoted from The Recommendation for Periodic Maintenance of a 
General-purpose Inverter published by JEMA.)
The periodic maintenance cycle depends on the installation environment and application conditions of 
the Servomotors and Servo Drives.
Recommended maintenance times are given below for Servomotors and Servo Drives. Use these for 
reference in periodic maintenance.
Caution
After replacing the Servo Drive, transfer to the new Servo Drive 
all data needed to resume operation, before restarting operation.
Equipment damage may result.
Do not repair the Servo Drive by disassembling it.
Electric shock or injury may result.

13-2 Servo Drive Lifetime
• The lifetime of Servo Drive depends on application conditions. When the ambient temperature is 
40°C and the average output is 70% of the rated output, the design life expectancy is ten years.
• The use of the Servo Drive in a hot environment shortens its lifetime. We recommend that the ambi-
ent temperature and the power supply ON time be reduced as much as possible to lengthen the life-
time of the Servo Drive.
• The lifetimes for the different parts of Servo Drive are given below.

AC Servomotors/Servo Drives 1S-series with Built-in EtherCAT® Communications User’s Manual (I586)
13-3 Servomotor Lifetime
The lifetimes for the different motor parts are listed below.
The operating conditions are determined as follows. 
• Operating ambient temperature: 40°C
• Within the range of allowable axial load
• Rated operation (rated torque and rated rotation speed)
• Installation as specified in this manual
• Operation is not repeated with the motor shaft rotation at an angle of 45° or less, which causes the 
fretting.
Oil seal can be replaced for repair.
When the Servomotor is used for a belt hook such as timing pulley, the radial load during motor opera-
tion is generally two or more times the static load. Consult with the belt and pulley manufacturers to 
adjust designs and system settings so that the motor allowable axial load is not exceeded even during 
operation. If the Servomotor is used under a shaft load that exceeds the allowable limit, the motor shaft 
can be broken and the bearings can be damaged.
Additional Information
If the Encoder Lifetime Warning occurs, we recommend you to replace the encoder within a few 
weeks.

A-1-3  Modes of Operation and Applied/Adjustment Functions
The relationships between the modes of operation of 1S-series Servo Drives with built-in EtherCAT 
communications and the applied/adjustment functions are shown below.
The operation mode of the 1S-series Servo Drives with built-in EtherCAT communications is changed 
as described below.
The operation mode of the Servo Drive is changed by setting the operation mode from the controller, 
and the Servo Drive can operate the Servomotor.
To change the operation mode, change the set value of Modes of operation (6060 hex). 
The operation mode is changed within two communication cycles after the set value is changed. When 
the Homing mode (hm) is changed to another operation mode, the operation mode is changed within 2 
ms after the set value is changed.
When you change the operation mode, also change the command value of the object mapped to the 
RxPDO.
For example, in Cyclic synchronous position mode (csp), which is a position control mode, Target 
Position (607A hex) is enabled as the command value, whereas in Cyclic synchronous velocity mode 
(csv), which is a velocity control mode, Target velocity (60FF hex) is enabled as the command value.
Therefore, when the operation mode changes from the position control mode to the velocity control 
mode, a valid command value must be set in Target velocity (60FF hex) at the same time.
You can check the actual operation mode of the Servo Drive from the Modes of operation display 
(6061 hex).
If Modes of operation (6060 hex) is set to a value other than 0 (nma), 1 (pp), 3 (pv), 6 (hm), 8 (csp), 9 
(csv), or 10 (cst), a warning will occur. If a warning occurs, the operation mode is not changed and the 
current operation mode is retained.

• If the operation mode is changed to Homing mode during the motor operation, the motor performs 
the stop operation according to the setting of Halt option code (605D hex).
• If a motion command of Homing mode or Profile position mode is input during a deceleration stop 
operation, the motor starts the Homing operation or Profile position operation.
If you change the operation mode to another mode while the motor is performing the homing operation, 
a command error will occur.
You can check the actual operation mode from the Modes of operation display (6061 hex).
Some of the bits in the Statusword (6041 hex) are dependent on the operation mode. Their relation-
ship with Modes of operation display (6061 hex) is shown in the following table:

This section describes the operation of the supported homing methods.
z Homing Methods 8 and 12: Homing by Home Proximity Input and Home Sig-
nal
These Homing methods use the Home Proximity Input that is enabled only in some parts of the drive 
range, and stop the motor when the home signal is detected.
The home signal is detected in the positive direction for Homing method 8 and in the negative direc-
tion for Homing method 12.
The operation start direction of the homing operation is as follows: When the Home Proximity Input 
is OFF, it is the same as the direction in which the home signal is detected. When the Home Proxim-
ity Input is ON, it is opposite to the direction in which the home signal is detected.
The operation direction reverses by the positive drive prohibition input.
A homing error occurs in the following cases. (Home error = 1)
• If the drive prohibition inputs in both directions are ON at the same time.
• If the drive prohibition input in one direction is ON, and the drive prohibition input in the opposite 
direction is turned ON although the rising edge of the Home Proximity Input is not detected.
• If the rising edge of the Home Proximity Input is detected in the home detection direction and then 
the drive prohibition input turns ON before the home signal is detected

Precautions for Correct Use
• If the home signal exists near the point where the Home Proximity Input turns ON or OFF, the 
first home signal after the Home Proximity Input is turned ON or OFF may not be detected. 
Set the Home Proximity Input so that the home signal occurs away from the point where the 
home Proximity Input turns ON /OFF.
• During the homing operation, the stop function for Drive Prohibition - Stop Selection is dis-
abled.
z Homing Methods 19 and 20: Homing without Home Signal
In these homing methods, only the Home Proximity Input is used. The Homing method 19 stops the 
homing operation when the Home Proximity Input turns OFF, and the Homing method 20 stops the 
homing operation when the Home Proximity Input turns ON.
The operation start direction of the homing operation is the positive direction when the Home Prox-
imity Input is OFF, and the negative direction when the Home Proximity Input is ON.
A homing error occurs in the following cases. (Home error = 1)
• If the drive prohibition inputs in both directions are ON at the same time.
• If turning ON or OFF of the Home Proximity Input is not detected before the drive prohibition input 
in the drive direction turns ON.
Precautions for Correct Use
During the homing operation, the stop function for Drive Prohibition - Stop Selection is dis-
abled.

z Homing Method 33 and 34: Homing with Home Signal
In these homing methods, only the Home signal is used.
The operation start direction of the homing operation is the negative direction when the homing 
method is 33, and the positive direction when the homing method is 34.
A homing error occurs in the following cases. (Home error = 1)
• If the drive prohibition inputs in both directions are ON at the same time.
• If the home signal is not detected before the drive prohibition input in the drive direction turns ON.
Precautions for Correct Use
During the homing operation, the stop function for Drive Prohibition - Stop Selection is dis-
abled.
z Homing Method 37: Present Home Preset
In this Homing method, the value of Home offset is considered as the present position.
You can use this method even when you are using an absolute encoder, but the position is not 
saved in Home offset (607C hex). When the control power is turned OFF or when Unit Restart is 
executed, the home set by this Homing method is disabled.
You can execute this Homing method only when the Modes of operation is set to Homing mode 
(hm) and in the Servo ON state.

• When you use the STO function via EtherCAT communications,confirm that the security 
function of EtherCAT master is enabled, and then execute Restore Default Parameters 
(subindex 01 hex) so that the PDO mapping is not changed.
• Use the Operation Authority Verification function in the NJ/NX-series CPU Unit to enable the 
security function. Set authorities so that synchronization of the transfer operations cannot be 
operated. Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for 
details.

A-2-5  PDO Mapping Objects
• You can change these objects only when the EtherCAT communications state is Pre-Operational 
(Pre-Op).
• The mapping you changed is not saved in the non-volatile memory. To use the mapping other than 
the default setting, specify objects each time you turn ON the power supply.
• You can map up to 10 objects in a PDO mapping. If you attempt to map 11 or more objects, an 
RxPDO Setting Error (Error. No. 90.5) will occur.
• The communications cycle you can set varies depending on the total size of mapped objects. For 
details, refer to A-1-3 Modes of Operation and Applied/Adjustment Functions on page A-5.
• If the same object is mapped more than once, the value of the last object is used.
• If any of the following operation is attempted, an ABORT code is returned.
a) Writing when the EtherCAT communications state is Safe-Operational (Safe-Op) or Operational 
(Op)
b) Writing with non-existent objects specified
c) Writing with incorrect object size specified
d) Writing with objects that cannot be mapped in the PDO mapping specified

For details on servo parameters, refer to Section 9 Details on Servo Parameters.
• This object is used to notify and clear the data of the Sysmac Error Status.
• Subindex 01 hex Sysmac Error Status notifies that the Servo Drive detected an error.
If you connect the Servo Drive with a Machine Automation Controller NJ/NX-series CPU Unit, map 
this object to the PDO.
• Subindex 02 hex Sysmac Error Status Clear enables a Machine Automation Controller 
NJ/NX-series CPU Unit to reset the error that occurred in the Servo Drive.
Additional Information
Sysmac Studio, by default, uses the 512th transmit PDO Mapping (1BFF hex) assignment to 
map the Sysmac Error Status (subindex 01 hex) automatically to the PDO.

z Description of bits specific to operation mode
• Target position ignored, Target velocity ignored, and Target torque ignored show whether the 
operation can follow the command. These bits change to 0 when operation cannot follow the com-
mand due to Drive Prohibition, Software Position Limit, etc.
• Status Toggle switches between 0 and 1 each time an RxPDO is received. The function of this bit is 
enabled or disabled with Function Settings (60DA hex).
• For how to use other bits, refer to Profile Position Mode on page 6-16 for the Profile position mode, 
Profile Velocity Mode on page 6-21 for the Profile velocity mode, and Homing Mode Specifications on 
page A-7 for the Homing mode.
• This object sets the operation of the Servo Drive during Shutdown (transition from the Operation 
enabled state to the Ready to switch on state). “During Shutdown” refers to the duration in which the 
Servo Drive decelerates and then stops after main circuit power OFF (Shutdown).
• When the running motor decelerates and the speed reaches 30 r/min or lower, the operation changes 
from the Deceleration Operation to the Operation after Stopping.
• The following error is cleared regardless of the set value.
12 to 13 Operation mode specific These bits are specific to the operation mode.
14 to 15 Manufacturer specific These are manufacturer specific bits. These bits are not 
used by 1S-series Servo Drives.

Precautions for Correct Use
• When the error is cleared, a process which makes the command position follow the present 
position comes into effect. To operate in Cyclic synchronous position mode (csp) after the 
Servo turns ON, reset the command coordinates in the host controller and then execute the 
operation. The Servomotor may move suddenly.
• If an error occurs while the main power supply is OFF, operation will follow Fault reaction 
option code (605E hex).

Precautions for Correct Use
• When the error is cleared, a process which makes the internal command position follow the 
actual position comes into effect. To execute commands that perform feeding for interpola-
tion after the Servo turns ON, reset the command coordinates in the host controller and then 
execute the operation. The Servomotor may move suddenly.
• If an error occurs while the Servo is OFF, operation will follow Fault reaction option code 
(605E hex).
• If the main power supply turns OFF while the Servo is OFF, operation will follow Shutdown 
option code (605B hex).

Precautions for Correct Use
When the error is cleared, a process which makes the command position follow the present 
position comes into effect. To operate in Cyclic synchronous position mode (csp) after the 
Servo turns ON, reset the command coordinates in the host controller and then execute the 
operation. The Servomotor may move suddenly.
• This object sets the mode of operation.
• The default value is 0 (not specified). Set the mode of operation from the master after the power sup-
ply is turned ON.
• A Command Warning (Error No. B1.00) occurs if the Servo is turned ON (Operation enabled = 1) with 
the default setting of 0 (not specified).
• Even when the default value 0 (not specified) is set again after changing the mode of operation, the 
mode of operation does not return to a not specified. The last mode of operation is retained.
• Similarly, when an unsupported mode of operation is set, the last mode is retained.
• When an unsupported mode of operation is set via SDO communications, an ABORT code is 
returned.

There is a short-circuit, ground 
fault, or contact failure on the U, 
V, or W motor cable
Correct the connection of the U, V, 
or W motor cable.
Confirm that the motor cables are 
not broken and connect them cor-
rectly.
There is a short-circuit on the wir-
ing of External Regeneration 
Resistor or the resistance value 
is small
If there is a short-circuit on the wir-
ing of External Regeneration 
Resistor, correct the wiring. 
Wire the External Regeneration 
Resistor correctly when using it. 
Use the recommended External 
Regeneration Resistor. If a resis-
tance value of the External Regen-
eration Resistor is small, 
excessive current will flow into the 
power module and cause a failure.
The insulation resistance failed 
between the U, V, or W motor 
cable and the motor ground wire
Replace the motor. Confirm that the insulation resis-
tance is insulated between the U, 
V, and W motor cable and the 
motor ground wire before using the 
motor.
Servo Drive failure If this event occurs again after you 
performed all corrections shown 
above, replace the Servo Drive.
Do not perform Servo ON/OFF fre-
quently. Doing so may cause a

The watchdog time was set 
incorrectly
If the watchdog time of the safety 
process data communications set-
ting is set to a value inappropriate 
for the communications cycle or 
the configuration, correct it, and 
transfer the setting to the Safety 
CPU Unit.
Set the watchdog time in consider-
ation of the actual configuration 
and surrounding environment.
The processing was not com-
pleted within the watchdog time 
because communications were 
not established due to the noise
If there is no improvement after 
you performed noise countermea-
sures, set the longer watchdog 
time, and transfer the setting to the

A-6 Version Information
This section describes the relationship between the unit versions of 1S-series Servo Drives and the 
Sysmac Studio versions, and the functions that were added or changed for each unit version.
This section also describes how the unit versions of 1S-series Servo Drives correspond to Sysmac Stu-
dio versions.
The following table gives the relationship between unit versions of 1S-series Servo Drives and the cor-
responding Sysmac Studio versions.
The operation specifications depending on combinations of unit versions of 1S-series Servo Drives and 
Sysmac Studio versions are given in this section.
z Using Sysmac Studio that does not Correspond to the Unit Version 1.1
When you use the Sysmac Studio that does not correspond to the unit version of Servo Drive, you 
cannot select the unit version of your Servo Drive from the device list of Sysmac Studio. When you 
use the Sysmac Studio without its update, select from the displayed unit versions.
Example: Unit version 1.1 of Servo Drive
Sysmac Studio version 1.17
Sysmac Studio version 1.17 corresponds to up to the unit version 1.0 of the Servo Drive. 
Therefore, you select the unit version 1.0. In this case, the Servo Drive operates as fol-
lows.
• The Servo Drive can use only functions of Sysmac Studio that are supported by the unit 
version 1.0.
• It is impossible to set the servo parameters that were added in the unit version 1.1. 
Therefore, the Servo Drive operates with the present set values.
• When you execute Initialize drive by Sysmac Studio, all servo parameters of the unit 
version 1.1 are restored to the default values.

z Using Sysmac Studio that Corresponds to the Unit Version 1.0
When you use the Sysmac Studio that corresponds to the unit version of Servo Drive, select the unit 
version of your Servo Drive from the device list of Sysmac Studio.
Example: Unit version 1.0 of Servo Drive
Sysmac Studio version 1.18
Sysmac Studio version 1.18 corresponds to up to the unit version 1.1 of the Servo Drive. 
Therefore, you select the unit version 1.0 from the device list. In this case, the Servo Drive 
can use all functions that are implemented in the unit version 1.0.
When you select the unit version 1.1 from the device list, the online connection to the unit 
version 1.0 of the Servo Drive is impossible. Select the unit version 1.0 from the device 
list.
The specifications for when you use the backup function of Sysmac Studio are given in this section.
• When you back up files by the EtherCAT slave configuration that is created as the unit version 1.0, 
and restore them to the unit version 1.1, only parameters that are covered by the unit version 1.0 are 
restored.
• When you back up files by the unit version 1.1 of the EtherCAT slave configuration, you cannot 
restore them to the unit version 1.0.
• When you use the latest unit version of Servo Drive, match EtherCAT slave configurations so as to 
back up all parameters, and recreate backup files.
This section gives the functions that were added or changed for each unit version of 1S-series Servo 
Drive.
