Fault tracing 211
4110 Control board
temperature
Control board temperature is
too high.
Check proper cooling of the drive.
Check the auxiliary cooling fan.
4210 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.
4290 Cooling Drive module temperature is
excessive.
Check ambient temperature. If it exceeds
40%/104 °F (frames R4
…R8) or if it
exceeds 50% /122 °F (frames R0
…R8),
ensure that load current does not exceed
derated load capacity of drive. See
chapter Technical data, section Derating
in the Hardware manual of the drive.
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.
42F1 IGBT temperature 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.
4310 Excess temperature Power unit module
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.
4380 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
4981 External temperature
1
Measured temperature 1 has
exceeded fault 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).
4982 External temperature
2
Measured temperature 2 has
exceeded fault 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).
4991 Safe motor
temperature
The CPTC-02 module
indicates overtemperature:
• motor temperature is too
high, or
• the thermistor is in
shortcircuit.
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 the sensor if faulty.
5080 Fan Cooling fan is stuck or
disconnected.
Check fan operation and connection.
Replace fan if faulty.
5081 Auxiliary fan broken An auxiliary cooling fan is
stuck or disconnected.
1 – Auxiliary fan 1 broken
2 – Auxiliary fan 2 broken
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
