Fault tracing 589
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 brake chopper and resistor (if
present).
Check deceleration time.
Use coast-to-stop function (if applicable).
Retrofit drive with brake chopper and
brake resistor.
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
“Y YY” specifies through which BCU
control unit channel the fault was
received.
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.
With parallel-connected modules, check
the auxiliary code (format XXXY YYZZ).
“Y YY” specifies through which BCU
control unit channel the fault was
received.
3280 Standby timeout Automatic restart failed (see
section Automatic restart on
page 113).
Check the condition of the supply
(voltage, cabling, fuses, switchgear).
3291 BU DC link difference Difference in DC voltages
between parallel-connected
inverter modules.
Check the auxiliary code (format XXXY
YYZZ). “XXX” specifies the source of the
first error (see “YYY”). “YYY” specifies
the module through which BCU control
unit channel the fault was received (1:
Channel 1, 2: Channel 2, 4: Channel 3,
8: Channel 4, …, 800: Channel 12).
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.
3385 Autophasing Autophasing routine (see
section Autophasing on page
96) has failed.
Try other autophasing modes (see
parameter 21.13 Autophasing mode) if
possible.
If the Turning with Z-pulse mode is
selected, check the zero pulse given by
the encoder.
Check that the motor ID run has been
successfully completed.
Clear parameter 98.15 Position offset
user.
Check that the encoder is not slipping on
the motor shaft.
Check that the motor is not already
turning when the autophasing routine
starts.
Check the setting of parameter 99.03
Motor type.
