Fault tracing 327
4981 External
temperature 1
Measured temperature 1
has exceeded fault limit.
Check the value of parameter
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
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
