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.
Calculated motor cable
temperature has exceeded
warning limit.
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.
The thermistor protection
module installed in slot 1
indicates overtemperature.
The thermistor protection
module installed in slot 2
indicates overtemperature.
The thermistor protection
module installed in slot 3
indicates overtemperature.
Control unit temperature is
excessive.
(none) Temperature above warning
limit
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.
With A3A1 or A3A2 on parallel-
connected inverter modules, the auxiliary
code indicates the affected module. The
format of the code is 000X XX00, where
"XXX" specifies the channel on the BCU
control unit.
If the problem persists, contact your local
ABB representative.
Check the settings of parameters
and 35.62.
Check the dimensioning of the motor
cable in regard to required load.
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 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 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 sensor if faulty.
Check the auxiliary code. See actions for
each code below.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
