Cause : Drive has detected load unbalance typically due to earth fault in motor or motor cable.

1. Check there are no power factor correction capacitors or surge absorbers in motor cable.

2. Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable.

3.Try running the motor in scalar control mode if allowed.(See parameter 99.04 Motor control mode.)

Check drive rectifier & IGBT using multimeter.

Check wiring.

Check drive hardware using multimeter.
