Fault tracing 325
3130
Input phase loss
Programmable fault:
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:
Incorrect input power
and motor cable
connection (i.e. input
power cable is connected
to drive motor
connection).
Check input power connections.
3210
DC link
overvoltage
Excessive intermediate
circuit
DC voltage.
Check that the supply voltage
matches the nominal input
voltage of the drive. Check the
supply line for static or transient
overvoltage.
Check brake chopper and resistor
(if present).
Check deceleration time. Use
coast-to-stop function (if
applicable). Retrofit drive with
brake chopper and 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.
3291
DC voltage
difference
Difference in DC voltages
between parallel-
connected inverter
modules.

3381
Output phase loss
Programmable fault:
Motor circuit fault due to
missing motor
connection (all three
phases are not
connected).
Connect motor cable.
