Cause : Drive has detected load unbalance typically due to earth fault in motor or motor cable.
Check there are no power factor correction
capacitors or surge absorbers in motor cable.
Check that there is no earth fault in motor or
motor cables:
- measure insulation resistances of motor and
motor cable.
