Firmware warning messages

Note: The list also contains events that only appear in the Event log.
Code
Warning
(hex)
A2A1 Current calibration
A2B3 Earth leakage
A2B4 Short circuit
A2BA IGBT overload
A3A1 DC link overvoltage
A3A2 DC link undervoltage
A3AA DC not charged
Motor cable overload
A480
A490 Incorrect temperature
sensor setup
Cause
Current offset and gain
measurement calibration will
occur at next start.
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.
Intermediate circuit DC voltage
too high (when the drive is
stopped).
Intermediate circuit DC voltage
too low (when the drive is
stopped).
The voltage of the intermediate
DC circuit has not yet risen to
operating level.
Calculated motor cable
temperature has exceeded
warning limit.
Sensor type mismatch
Faulty wiring between an
encoder interface module and
the temperature sensor.
Fault tracing 569
What to do
Informative warning. (See parameter
99.13 ID run requested.)
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 heat sink fins for dust pick-up.
Check motor power against drive power.
Check the supply voltage setting
(parameter 95.01 Supply
that the wrong setting of the parameter
may cause the motor to rush
uncontrollably, or may overload the brake
chopper or resistor.
Check the supply voltage.
With A3A1 or A3A2 on parallel-
connected inverter modules, the auxiliary
code indicates the affected module. The
format of the code is 0000X XX00, where
"XXX" specifies the channel on the BCU
control unit.
If the problem persists, contact your local
ABB representative.
Check the settings of parameters
and 35.62.
Check the dimensioning of the motor
cable in regard to required load.
Check the settings of temperature source
parameters 35.11 and 35.21
91.21 and 91.24.
Check the wiring of the sensor.
The auxiliary code identifies the interface
module. (0 = Module 1, 1 = Module 2).
