Code
Fault
(hex)
2281 Calibration
2310 Overcurrent
2330 Earth leakage
Programmable fault:
Earth fault
2340 Short circuit
2381 IGBT overload
3130 Input phase loss
Programmable fault:
Supply phase loss
Cause
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).
Output current has exceeded
internal fault limit.
Drive has detected load
unbalance typically due to
31.20
earth fault in motor or motor
cable.
Short-circuit in motor cable(s)
or motor
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Intermediate circuit DC voltage
is oscillating due to missing
31.21
input power line phase or
blown fuse.
Fault tracing 363
What to do
Try performing the current calibration
again (select Current measurement
calibration at parameter 99.13). If the
fault persists, contact your local ABB
representative.
Check motor load.
Check acceleration times in parameter
group 23 Speed reference ramp
control), 26 Torque reference chain
(torque control) or 28 Frequency
reference chain (frequency control). Also
check parameters 46.01 Speed
46.02 Frequency scaling
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).
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
Motor control mode.)
If no earth fault can be detected, contact
your local ABB representative.
Check motor and motor cable for cabling
errors.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check input power line fuses.
Check for loose power cable
connections.
Check for input power supply imbalance.
