A491 External temperature
1
(Editable message text)
Measured temperature 1 has
exceeded warning limit. Check the value of parameter 35.02
Measured temperature 1 .
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of
35.13 Temperature 1
warning limit .
A492 External temperature
2
(Editable message text)
Measured temperature 2 has
exceeded warning limit. Check the value of parameter 35.03
Measured temperature 2 .
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of
35.23 Temperature 2
warning limit .
A497 Motor temperature 1
(Editable message text)
The thermistor protection
module installed in slot 1
indicates overtemperature. Check the cooling of the motor.
Check the motor load and drive ratings.
Check the wiring of the temperature
sensor. Repair wiring if faulty.
Measure the resistance of the sensor.
Replace sensor if faulty.
A498 Motor temperature 2
(Editable message text)
The thermistor protection
module installed in slot 2
indicates overtemperature.
A499 Motor temperature 3
(Editable message text)
The thermistor protection
module installed in slot 3
indicates overtemperature.
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.
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.
A4B0 Excess temperature Power unit temperature is
excessive. Check ambient conditions.
Check air flow and fan operation.
Check the setting of
31.36 Aux fan fault
function (if present).
Check heatsink fins for dust pick-up.
Check motor power against drive power.
