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.
Temperature cannot be
supervised due to incorrect
adapter setup.
Measured temperature 1 has
exceeded warning limit.
Measured temperature 2 has
exceeded warning limit.
Control board temperature is
too high.
(none) Temperature above warning

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
resistor.
Check the supply voltage.
If the problem persists, contact your
local ABB representative.

Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
