Table 13-2 Fault Messages (Alphabetical by Keypad Text)
Fault Fault # Cause What to do
Calibration 2281 Measured offset of output
phase current
measurement or
difference between output
phase U2 and W2 current
measurement is too great
(the values are updated
during current calibration).
Try performing the current calibration again (select Current
measurement calibration at parameter 99.13). If the fault
persists, contact your local ABB representative.
Overcurrent 2310 Output current has
exceeded internal fault
limit.
Check motor load.
Check acceleration times in parameter group 23 Speed
reference ramp (speed control), 26 Torque reference chain
(torque control) or 28 Frequency reference chain
(frequency control). Also check parameters 46.01 Speed
scaling, 46.02 Frequency scaling and 46.03 Torque
scaling.
Check motor and motor cable (including phasing and
delta/star connection).
Check there are no contactors opening and closing in
motor cable.
Check that the start-up data in parameter group 99
corresponds to the motor rating plate.
Check that there are no power factor correction
capacitors or surge absorbers in motor cable.
Check encoder cable (including phasing).
Earth leakage
Programmable fault: 31.20
Earth fault
2330 Drive has detected load
unbalance typically due to
earth fault in motor or
motor cable.
Check there are no power factor correction capacitors or
surge absorbers in motor cable.
Check for an earth fault in motor or motor cables by
measuring the insulation resistances of motor and motor
cable.
Try running the motor in scalar control mode if allowed.
(See parameter 99.04 Motor control mode.)
If no earth fault can be detected, contact your local ABB
representative.
Short circuit 2340 Short-circuit in motor
cable(s) or motor
Check motor and motor cable for cabling errors.
Check there are no power factor correction capacitors or
surge absorbers in motor cable.
After correcting the cause of the fault, reboot the control
unit (using parameter 96.08 Control board boot) or by
cycling
power.
IGBT overload 2381 Excessive IGBT junction
to case temperature. This
fault protects the IGBT(s)
and can be activated by a
short circuit in the motor
cable.
Check motor cable.
Check ambient conditions.
Check air ow and fan operation.
Check heatsink ns for dust pick-up.
Check motor power against drive power.
Input phase loss
Programmable fault: 31.21
Supply phase loss
3130 Intermediate circuit DC
voltage is oscillating due
to missing input power
line phase or blown fuse.
Check input power line fuses.
Check for loose power cable connections.
Check for input power supply imbalance.
Charge relay lost 3180 No acknowledgement
received from charge
relay.
Contact your local ABB representative.
Cross connection
Programmable fault: 31.23
Cross connection
3181 Incorrect input power and
motor cable connection
(i.e. input power cable is
connected to drive motor
connection).
Check input power connections.
