Diagnostics
16 EARTH FAULT 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.
• 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.
17 RESERVED
18 THERM FAIL Internal fault. The thermistor measuring the internal temperature of the
drive is open or shorted. Contact your local ABB representative.
19
OPEX LINK Internal fault. A communication-related problem has been detected on the
fiber optic link between the control and OINT boards. Contact your local
ABB sales representative.
20 OPEX PWR Internal fault. Low voltage condition detected on OINT power supply.
Contact your local ABB representative.
21
CURR MEAS Internal fault. Current measurement is out of range. Contact your local ABB
representative.
22
SUPPLY PHASE Ripple voltage in the DC link is too high. Check for and correct:
• Missing mains phase.
• Blown fuse.
23 If this error code appears, refer to the appropriate accessory manual.
24 RESERVED Not used.
25 RESERVED Not used.
26 DRIVE ID Internal fault. Configuration Block Drive ID is not valid. Contact your local
ABB sales representative.
27
CONFIG FILE Internal configuration file has an error. Contact your local ABB sales
representative.
28
SERIAL 1 ERR Fieldbus communication has timed out. Check for and correct:
• Fault setup (3018
COMM FAULT FUNC and 3019 COMM FAULT TIME).
• Communication settings (Group 51 or 53 as appropriate).
• Poor connections and/or noise on line.
29
EFB CON FILE Error in reading the configuration file for the embedded fieldbus.
30
FORCE TRIP Fault trip forced by the fieldbus. See the fieldbus User’s Manual.
31
EFB 1 Fault code reserved for the embedded fieldbus (EFB) protocol application.
The meaning is protocol dependent.
32 EFB 2
33
EFB 3
34 MOTOR PHASE Fault in the motor circuit. One of the motor phases is lost. Check for and
correct:
• Motor fault.
• Motor cable fault.
• Thermal relay fault (if used).
• Internal fault.
