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.
