Cause
Short-circuit in motor cable(s)
or motor.
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.
Measured temperature 1 has
exceeded warning limit.
Measured temperature 2 has
exceeded warning limit.

Fault tracing 361
What to do
Check motor and motor cable for cabling
errors.
Check motor and motor cable (including
phasing and delta/star connection).
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
See chapter Electrical installation,
section Checking the insulation of the
assembly in the Hardware manual of the
drive.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
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.
If the problem persists, contact your local
ABB representative.
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 parameter
Measured temperature 2.
Check the cooling of the motor (or other
equipment whose temperature is being
measured).
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 (frames R5
exceeds 50 °C /122 °F (frames R0
ensure that load current does not exceed
derated load capacity of drive. See
chapter Technical data, section Derating
in the Hardware manual of the drive.
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.
