EXTERNAL FAULT
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
Not used.

Internal fault. The thermistor measuring the internal temperature of the
THERM FAIL
drive is open or shorted. Contact your local ABB representative.
Internal fault. A communication-related problem has been detected on the
OPEX LINK
fiber optic link between the control and OINT boards. Contact your local
ABB representative.
Internal fault. Low voltage condition detected on OINT power supply.
OPEX PWR
Contact your local ABB representative.
Internal fault. Current measurement is out of range. Contact your local ABB
CURR MEAS
representative.
Ripple voltage in the DC link is too high. Check for and correct:
SUPPLY PHASE
• Missing mains phase.
• Blown fuse.
The drive is not detecting a valid encoder signal. Check for and correct:
ENCODER ERR
• Encoder presence and proper connection (reverse wired, loose
connection or short circuit).
• Voltage logic levels are outside of the specified range.
• A working and properly connected Pulse Encoder Interface Module,
OTAC-01.
• Wrong value entered in parameter 5001
only be detected if the error is such that the calculated slip is greater
than 4 times the rated slip of the motor.
• Encoder is not being used, but parameter 5002
