Cause : Drive has detected load unbalance typically due to earth fault in motor or motor cable.
1. Check for an earth fault in motor or motor cables by measuring the insulation resistances of motor and motor cable.
2. Check Earthing.
3. If problem continue then check drive using multi-meter.
4. Check rectifier & IGBT using multimeter.
