FANUC common alarm list:

FANUC common alarm list:
SP9031 SSPA: 31 motor lock or detector disconnection
Amplifier alarm number: 31
Cause of alarm: The motor does not rotate at the specified speed, the motor stalls, and in most cases the motor does not rotate.
Investigating ideas:
Check whether the load of the motor is too large, or whether it is blocked by other peripheral hardware.
If the motor rotates normally, replace the encoder feedback cable.
During the commissioning of the electric spindle and DD motor, confirm the phase sequence of the power line of the spindle motor and parameters P4104 and P4106.
Considering the use of the main shaft, the load is too heavy and the car is boring.
2SP9032 SSPA:32 Serial LSI RAM failure
Amplifier alarm number: 32
Cause of alarm: It was detected that the control circuit of the spindle amplifier was abnormal.
Troubleshooting idea: replace the spindle amplifier.
3SP9033 SSPA: 33 DC LINK insufficient charge
Amplifier alarm number: 33
Cause of alarm: When the electromagnetic contactor is ON, the DC power supply voltage of the power circuit part is insufficiently charged (common power supply alarm display 5)
Investigating ideas:
Check and modify the power supply voltage.
Replace the common power supply.
It often appears together with SV0442, check the CX48 port wiring.
4SP9034 SSPA:34 The parameter is illegal
Amplifier alarm number: 34
Cause of alarm: A parameter exceeding the allowable value is set.
Troubleshooting idea: Use the spindle motor code or parameter list to reload the spindle parameters.
5SP9036 SSPA:36 error counter overflow
Amplifier alarm number: 36
Alarm reason: Error counter overflows.
Investigating ideas:
Confirm whether the position gain is too large and modify it.
Confirm the deceleration ratio parameter settings of each gear.
6SP9037 SSPA: 37 speed detector setting error
Amplifier alarm number: 37
Cause of alarm: The parameter setting of the pulse number of the speed detector is incorrect.
Troubleshooting idea: Use the spindle motor code or parameter list to reload the spindle parameters.
7SP9041 SSPA: 41 Position encoder one-rotation signal error
Amplifier alarm number: 41
Cause of alarm: The system detects an abnormal encoder one-rotation signal.
Investigating ideas:
If the one-rotation signal cannot be detected (use SERVO GUIDE to test SFLG1), check the encoder and the encoder feedback line. .
If it is confirmed that a one-rotation signal is detected, check the encoder setting parameters and gear ratio parameters.
8SP9042 SSPA: 42 One-rotation signal error of position encoder
Amplifier alarm number: 42
Cause of alarm: The system detects an abnormal encoder one-rotation signal.
Troubleshooting ideas: Check the encoder and encoder feedback line.
