A3C1
DC voltage difference
Difference in DC
voltages between
parallel-connected
inverter modules.
Contact your local ABB representative.
A480
Motor cable overload
Calculated motor cable
temperature has
exceeded warning limit.
Check the settings of parameters
and
Check the dimensioning of the motor
cable in regard to required load.
A490
Incorrect temperature
sensor setup
Sensor type mismatch or
Check the settings of supervision
source parameters
against
Faulty wiring between an
encoder interface
module and the
temperature sensor.
Check the wiring of the sensor.
The auxiliary code identifies the
interface module. (0 = Module 1, 1 =
Module 2).
A491
External temperature
(Editable message text)
Measured temperature 1
or 2 has exceeded
warning limit.
Check the values of parameters
Check the cooling of the motor (or
other equipment whose temperature is
being measured).
Check the warning limits for measured
temperatures 1 and 2 in parameter
group
.
A492
External temperature 2
(Editable message text)
Measured temperature 2
has exceeded warning
limit.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of
.
A4A0
Control board
temperature
Control unit temperature
is excessive.
Check the auxiliary code. See actions
for each code below.
(none) Temperature above
warning limit
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
1 Thermistor broken
Contact an ABB service representative
for control unit replacement.
A4A1
IGBT overtemperature
Estimated drive IGBT
temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A4A9
Cooling
Drive module
temperature is
excessive.
Check ambient temperature. If it
exceeds 40 °C (104 °F), ensure that
load current does not exceed derated
load capacity of drive. See appropriate
Hardware Manual.
Check drive module cooling air flow
and fan operation.
Check inside of cabinet and heatsink
of drive module for dust pick-up. Clean
whenever necessary.
