Cause
Control board temperature is
too high.
temperature is excessive.
Drive module temperature is
excessive.
Drive IGBT temperature is
excessive.
Power unit module
temperature is excessive.
High temperature difference
between the IGBTs of different
phases.
Measured temperature 1 has
exceeded fault limit.
Measured temperature 2 has
exceeded fault limit.
The CPTC-02 module
indicates overtemperature:
• motor temperature is too
high, or
• the thermistor is in
shortcircuit.
Cooling fan is stuck or
disconnected.
An auxiliary cooling fan is
stuck or disconnected.
1 – Auxiliary fan 1 broken
2 – Auxiliary fan 2 broken
Fault tracing 211
What to do
Check proper cooling of the drive.
Check the auxiliary cooling fan.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient temperature. If it exceeds
40%/104 °F (frames R4
exceeds 50% /122 °F (frames R0
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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
Check the motor cabling.
Check cooling of drive module(s).
Check the value of parameter
Measured temperature 1.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of parameter
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
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.
Check fan operation and connection.
Replace fan if faulty.
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
