How can resolve problem F0016 EARTH FAULT Fault in ABB ACS550 Drive ?
Possible ground fault detected in the motor or motor cables. The drive
monitors for ground faults while the drive is running and while the drive is
not running. Detection is more sensitive when the drive is not running and
can produce false positives.
Possible corrections:
• Check for/correct faults in the input wiring.
• Verify that motor cable does not exceed maximum specified length.
• Decrease the detection level for earth fault with parameter 3028 EARTH
FAULT LVL.
• A delta grounded input power supply and motor cables with high
capacitance may result in erroneous error reports during non-running
tests. To disable response to fault monitoring when the drive is not
running, use parameter 3023 WIRING FAULT. To disable response to all
ground fault monitoring, use parameter 3017 EARTH FAULT.
Note: Disabling earth fault (ground fault) may void the warranty
