The AC drive detects an abnormal increase in current
1. Check whether the motors horsepower corresponds to the AC drive output power.
2. Check the wiring connections between the AC drive and motor for possible short circuits.
3. Increase the Acceleration time.
4. Check for possible excessive loading conditions at the motor.
5. If there are any abnormal conditions when operating the AC drive after short-circuit being removed.
Check drive rectifier & IGBT using multimeter.
Check wiring.
Check drive hardware using multimeter.
