352 Fault tracing
2340 Short circuit Short-circuit in motor cable(s)
or motor 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.
2381 IGBT overload Excessive IGBT junction to
case temperature. This fault
protects the IGBT(s) and can
be activated by a short circuit
in the 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.
3130 Input phase loss
Programmable fault: 31.21
Supply phase loss
Intermediate circuit DC voltage
is oscillating due to missing
input power line phase or
blown fuse. Check input power line fuses.
Check for loose power cable
connections.
Check for input power supply
imbalance.
3181 Wiring or earth fault
Programmable fault: 31.23
Wiring or earth fault
Incorrect input power and
motor cable connection (ie.
input power cable is connected
to drive motor connection). Check input power connections.
3210 DC link overvoltage Excessive intermediate circuit
DC voltage. 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.
3220 DC link undervoltage Intermediate circuit DC voltage
is not sufficient because of a
missing supply phase, blown
fuse or fault in the rectifier
bridge. Check supply cabling, fuses and
switchgear.
3381 Output phase loss
Programmable fault: 31.19
Motor phase loss
Motor circuit fault due to
missing motor connection (all
three phases are not
connected). Connect motor cable.
4110 Control board
temperature Control board temperature is
too high. Check proper cooling of the drive.
Check the auxiliary cooling fan.
4210 IGBT overtemperature Estimated drive IGBT
temperature is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
