Cause : Drive has detected load unbalance typically due to earth fault in motor or motor cable.
(programmable Fault Function 30.17)
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.
