Fault tracing 331
A2B4 Short circuit
Short-circuit in motor
cable(s) or motor.
Check motor and motor cable for
cabling errors.
Check motor and motor cable
(including phasing and delta/star
connection).
Check for an earth fault in motor or
motor cables by measuring the
insulation resistances of motor and
motor cable. See chapter
Electrical
installation
, section
Checking the
insulation of the assembly
in the
hardware manual of the drive.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
A2BA IGBT overload
Excessive IGBT junction to
case temperature. This
warning protects the IGBT(s)
and can be activated by a
short circuit in the 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.
A3A1
DC link overvoltage
Intermediate circuit DC
voltage too high (when the
drive is stopped).
Check the supply voltage setting
).
Note 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.
If the problem persists, contact your
local ABB representative.
A3A2
DC link undervoltage Intermediate circuit DC
voltage too low (when the
drive is stopped).
A3AA DC not charged
The voltage of the
intermediate DC circuit has
not yet risen to operating
level.
A490 Incorrect
temperature sensor
setup
Sensor type mismatch.
Check the settings of temperature
source parameters
.
A491
External temperature
1
(Editable message
text)
Measured temperature 1 has
exceeded warning limit.
Check the value of parameter
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of
.
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.
