Possible ground fault detected in the motor or motor cables. The drive
EARTH FAULT
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.
• 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
ground fault monitoring, use parameter 3017
Motor load is lower than expected. Check for and correct:
UNDERLOAD
• Disconnected load.
• Parameters 3013
Internal fault. The thermistor measuring the internal temperature of the
THERM FAIL
drive is open or shorted. Contact your local ABB sales representative.
Internal fault. A communication-related problem has been detected on the
OPEX LINK
fiber optic link between the OITF and OINT boards. Contact your local ABB
sales representative.
Internal fault. Low voltage condition detected on OINT power supply.
OPEX PWR
Contact your local ABB sales representative.
Internal fault. Current measurement is out of range. Contact your local ABB
CURR MEAS
sales representative.
Ripple voltage in the DC link is too high. Check for and correct:
SUPPLY PHASE
• Missing mains phase.
• Blown fuse.
If this error code appears, refer to the appropriate accessory manual.
Motor speed is greater than 120% of the larger (in magnitude) of 2001
