Cause
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 feedback missing.
An auxiliary cooling fan is stuck
or disconnected.
0001 – Auxiliary fan 1 broken
0002 – Auxiliary fan 2 broken
Safe motor temperature fault is
generated and STO
event/fault/warning is not gener-
ated.
STO hardware diagnostics detec-
ted an hardware failure.
Safe torque off function is active.
Power unit memory is cleared.
Mismatch of drive hardware and
memory information.
Fault in internal temperature
measurement.
Duplicated measurements are
beyond limits.
Excessive hardware temperat-
ure.
Communication failure to stand-
ard I/O.
Communication errors between
drive control unit and power unit.
Connection lost between drive
control unit and power unit.
Internal communication error.
Measurement circuit fault.
Power unit power supply failure.
What to do
Check motor cabling and drive module(s)
cooling.
Check parameter 35.02 Measured temper-
ature 1, motor cooling and fault limit for
measured temperature 1.
Check parameter 35.03 Measured temper-
ature 2, motor cooling and fault limit for
measured temperature 1.
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. Re-
place the sensor if faulty.
See A581 Fan (page 70).
Check auxiliary fan(s) and connection(s).
Replace fan if faulty.
Check connection between the relay output
of the module and the STO terminal.
Contact ABB for hardware replacement.
Check safety circuit connections parameter
95.04 Control board supply.

Cycle power to the drive. You may have to
be repeat this.
