Cause
Intermediate circuit DC voltage
too high (when the drive is
stopped).
Intermediate circuit DC voltage
too low (when the drive is
stopped).
The voltage of the intermediate
DC circuit has not yet risen to
operating level.
Difference in DC voltages
between parallel-connected
inverter modules.
Sensor type mismatch
Faulty wiring between an
encoder interface module and
the temperature sensor.
Measured temperature 1 has
exceeded warning limit.
Measured temperature 2 has
exceeded warning limit.

High temperature difference
between the IGBTs of different
phases.
What to do
Check the supply voltage setting
(parameter 95.01 Supply
that the wrong setting of the parameter
may cause the motor to rush
uncontrollably, or may overload the brake
chopper or resistor.
Check the supply voltage.
If the problem persists, contact your local
ABB representative.
Contact your local ABB representative.
Check the settings of temperature source
parameters 35.11 and 35.21
91.21 and 91.24.
Check the wiring of the sensor.
The auxiliary code (see the event log)
identifies the interface module. (0 =
Module 1, 1 = Module 2).
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 35.13 Temperature 1
warning limit.
Check the value of parameter
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
Check the value of 35.23 Temperature 2
warning limit.
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 °C (104 °F), ensure that load current
does not exceed derated load capacity of
drive. See appropriate Hardware Manual.
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 the motor cabling.
Check cooling of drive module(s).
