Check the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
Check the cooling fan.
12.3.38 Fault Code 14, ID 132 - AC Drive Overtemperature (Fault, Board)
Cause
Too high a temperature in the heat sink of the power unit or in the power board.
The temperature limits of the heat sink are different in all the enclosure sizes.
Troubleshooting
Check the actual amount and flow of cooling air.
Examine the heat sink for dust.
Check the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
Check the cooling fan.
12.3.39 Fault Code 14, ID 133 - AC Drive Overtemperature (Alarm, Board)
Cause
Too high a temperature in the heat sink of the power unit or in the power board.
The temperature limits of the heat sink are different in all the enclosure sizes.
Troubleshooting
Check the actual amount and flow of cooling air.
Examine the heat sink for dust.
Check the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
Check the cooling fan.
12.3.40 Fault Code 14, ID 134 - AC Drive Overtemperature (Fault)
Cause
Power unit auxiliary temperature is too high.
Troubleshooting
Check the actual amount and flow of cooling air.
Examine the heat sink for dust.
Check the ambient temperature.
Make sure that the switching frequency is not too high in relation to the ambient temperature and the motor load.
Check the cooling fan.
