Cause
Excessive IGBT junction to
case temperature. This
warning protects the IGBT(s)
and can be activated by a short
circuit in the motor cable.
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.
Problem with motor
temperature measurement.
0001 Sensor type mismatch
0002 Temperature under limit
0003 Short circuit
0004 Open circuit
Measured temperature 1 has
exceeded warning limit.
Measured temperature 2 has
exceeded warning limit.
What to do
Check motor cable.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive power.
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 auxiliary code (format 0XYY
ZZZZ).
"X" identifies the affected temperature
monitoring function (0 = parameter 35.11,
1 = parameter 35.21).
"YY" indicates the selected temperature
source, ie. the setting of the selection
parameter in hexadecimal.
"ZZZZ" indicates the problem (see
actions for each code below).
Check parameters 35.11/35.21
91.21/91.24.
Check parameters
35.11...35.14/35.21...35.24
91.21/91.24 if sensor is connected to an
encoder interface).
Check the sensor and its wiring.
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.
