Warning messages

Note: The list also contains events that only appear in the Event log.
Code
Warning
(hex)
A2A1 Current calibration
A2B1 Overcurrent
A2B3 Earth leakage
A2B4 Short circuit
A2BA IGBT overload
Cause
Current offset and gain
measurement calibration will
occur at next start.
Output current has exceeded
internal fault limit.
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
Short-circuit in motor cable(s)
or motor.
Excessive IGBT junction to
case temperature. This
warning protects the IGBT(s)
and can be activated by a short
circuit in the motor cable.
Fault tracing 473
What to do
Informative warning. (See parameter
99.13 ID run requested.)
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.
