What to do
Check the value of parameter
Measured temperature
Check the cooling of the motor (or
other equipment whose temperature
is being measured).
Check the value of 35.23 Temperature
2 warning limit.
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.
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.
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.
Check the auxiliary code. See actions
for each code below.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Contact an ABB service
representative for control unit
replacement.
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.
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.
