Cause

1. Fan damaged;
2. Ambient temperature too high;
3. Overload faults repeatedly reset by switching power off after an overload;
4. Servo drive mounting orientation or spacing from other servo drives inappropriate;
5. Servo drive fault;
6. Drive or motor damaged

Corrective action

1. Check whether the fan rotates during operation and replace the fan or drive;
2. Measure the ambient temperature, improve servo drive cooling, and lower the ambient temperature;
3. Check the fault records for overload faults and change the fault reset method: wait 30s after overload before resetting. Drive and motor power ratings are too small; increase their capacity, increase acceleration/deceleration time, and reduce the load;
4. Verify the servo drive installation condition and install it according to the servo drive installation standards;
5. Check whether the fault persists after power is turned off for 5 minutes and restarted; if it persists after restart, replace the servo drive
