Fanuc servo motor power module alarm-03 troubleshooting
1.Check whether the main circuit of the Fanuc motor is abnormal and cause the power module to alarm, if the temperature rise of the radiator of the main circuit of the Fanuc servo motor is abnormal, the power module will also cause an alarm, then only need to confirm whether the radiator of the main circuit is damaged to troubleshoot.
2.When checking the cold air fan of Fanuc servo motor, the fan of the power module and the ventilation fan of the electric cabinet should be detected together, if the fan is damaged or the ventilation of the machine is not good, the temperature inside the machine will be too high and cause the fault, so the three should be detected together, if there is a fault, the machine will have an alarm failure.
3.The power module alarm caused by the power supply of Fanuc servo motor is too high.
For electrical equipment, check whether the power supply part of the machine exceeds the normal use range of the machine, and adjust it in time if it is exceeded.
