Cause
Short-circuit in motor cable(s)
or motor
Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the motor cable.
Intermediate circuit DC voltage
is oscillating due to missing
31.21
input power line phase or
blown fuse.
Incorrect input power and
motor cable connection (ie.
31.23
input power cable is connected
to drive motor connection).
Excessive intermediate circuit
DC voltage.
Intermediate circuit DC voltage
is not sufficient because of a
missing supply phase, blown
fuse or fault in the rectifier
bridge.
Motor circuit fault due to
missing motor connection (all
31.19
three phases are not
connected).
Control board temperature is
too high.
temperature is excessive.
What to do
Check motor and motor cable for
cabling errors.
Check there are no power factor
correction capacitors or surge
absorbers in motor cable.
Cycle the power to the drive.
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 input power line fuses.
Check for loose power cable
connections.
Check for input power supply
imbalance.
Check input power connections.
Check that overvoltage control is on
(parameter 30.30 Overvoltage
control).
Check that the supply voltage
matches the nominal input voltage of
the drive.
Check the supply line for static or
transient overvoltage.
Check resistor (if present).
Check deceleration time.
Use coast-to-stop function (if
applicable).
Retrofit drive with brake resistor.
Check that the brake resistor is
dimensioned properly and the
resistance is between acceptable
range for the drive.
Check supply cabling, fuses and
switchgear.
Connect motor cable.
Check proper cooling of the drive.
Check the auxiliary cooling fan.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
