Ошибка фанук sp9015

The switch sequence in spindle switching/speed range switching operation is abnormal. The switching MCC contact status check signal and command do not match.

1 Check and correct the ladder sequence.
2 Replace the switching MCC.

Spindle Amplifier indication 15

NOTE
*1 Note that the meanings of the Spindle Amplifier indications differ depending on
which LED, the red or yellow LED, is on. When the red LED is on, the Spindle
Amplifier indicates a 2-digit alarm number. When the yellow LED is on, the
Spindle Amplifier indicates an error number that designates a sequence problem
(for example, when a rotation command is entered with the emergency stop
state not released).
See “Error Codes (Serial Spindle).”
*2 For serial spindle alarms with a number not listed, refer to the following
documents depending on the spindle motor to which a connection is actually
made.

The Maintenance Technicians App

FANUC CNC system has two mainstream servo drive amplifiers — αi and βi series servo drive amplifiers.

The αi series servo drive amplifier is a high-performance, cost-effective drive product with modular structure, which consists of three servo modules, including: power amplifier (PSM: Power Supply Module), Spindle Amplifier (SPM: Spindle Module), servo amplifier (SVM: Servo Module).

PSM servo amplifier: It mainly provides power and safety control for servo module and spindle module.
SPM servo amplifier: mainly provides power and control for the spindle motor.
SVM servo amplifier: mainly provides power and control for servo motors, such as servo drive amplifiers for X, Y, and Z axes.

Cause for alarm: The feedback speed of the spindle cannot keep up with the commanded speed of the spindle. (The actual speed of the motor is quite different from the command speed)
Troubleshooting:

1) Check whether the load is too heavy and the spindle cannot keep up with the commanded speed.
2) Check whether the initialization parameters of the spindle motor are abnormal.
3) Check amplifier and spindle motor for any abnormality.
4) Change parameter P4082.

Cause for alarm: Phase loss detected on power supply. If there is lacking one phrase of the three-phase AC 200V of the main shaft, the control board can detect it and issue an alarm No. 04.
Troubleshooting:

1) Check the input interface of the power cord.
2) Check the wiring of the CX48 interface.
3) Note the winding switching between the high winding motor and the low winding motor.

Cause for alarm: The motor temperature sensor is disconnected.
Troubleshooting:

1) Reinitialize the spindle motor parameters, and pay attention to the encoder parameters.
2) Check the feedback circuit of the spindle motor.
3) Check the temperature sensor of the spindle motor.
4) Check the spindle motor amplifier.

Cause for alarm: The motor exceeds 115% of the maximum speed (parameter standard setting).
Troubleshooting:

1) Check the initialization parameters of the spindle motor.
2) Check the phase sequence of the spindle power cable.
3) Check the spindle motor amplifier.

Cause for alarm: The temperature of the radiator used to cool the power semiconductor rises abnormally.
Troubleshooting:

1) Improve the cooling capacity of the cooling device.
2) Check the external radiator cooling fan.
3) Replace the spindle amplifier.

Cause for alarm: The input power supply voltage of the spindle amplifier is low.
Troubleshooting:

1) Check amplifier input supply voltage.
2) Replace the power input cable or replace the amplifier.

Cause for alarm:
When the spindle motor rotates at high speed, the inertia is large. So when the power supply of the motor is cut off, the regenerative braking function of the spindle does not work, and the spindle motor cannot stop immediately.
Troubleshooting:

1) Use the common power supply to detect the overvoltage of the DC Link part (the common power supply alarm displays 7), check the input voltage, and if possible, use the filter to check. It may cause voltage stability degradation.
2) If the selection of the public power supply is wrong, exceeding the maximum output specification of the public power supply, please contact the FANUC representative to re-calculate whether the selection of the power supply module is correct.
3) Confirm that the spindle initialization parameters are normal, and try to modify the parameter P4672 at the same time.
4) Replace the amplifier.

Cause for alarm: Spindle motor overcurrent.
Troubleshooting:

1) Check the initialization of the parameters specific to the spindle motor.
2) Check the insulation filling of the cable and check whether the phase sequence of the power cable is connected correctly.
3) Replace the spindle amplifier.
4) If this alarm occurs when switching windings, there may be a problem with the contactor and PMC timing.

Cause for alarm: The sequence of spindle switching/output switching is abnormal. (The switching operation sequence of output switching control or spindle switching control is incorrect.)
Troubleshooting:

1) When the spindle output is switched, an alarm will be generated, and the PMC signal needs to be changed to switch the spindle.
2) If an alarm occurs when the spindle rotates normally, parameter P4160 should be increased.

Cause for alarm: The overload current of the spindle amplifier is detected.
Troubleshooting:

1) Make sure that the spindle initialization parameters are set correctly.
2) Change the operating conditions of the spindle motor to reduce the load.
3) Check whether the parameters of the 2-winding motor and the winding switching part in the ladder diagram are correct.
4) Replace the spindle amplifier.
