Code
Fault
(hex)
3210 DC link overvoltage
3220 DC link undervoltage
3280 Standby timeout
3291 BU DC link difference
3381 Output phase loss
Programmable fault:
Motor phase loss
3385 Autophasing
Cause
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.
Automatic restart failed (see
section Automatic restart
page 113).
Difference in DC voltages
between parallel-connected
inverter modules.
Motor circuit fault due to
missing motor connection (all
31.19
three phases are not
connected).
Autophasing routine (see
section Autophasing
96) has failed.
What to do
Check that overvoltage control is on
(parameter
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.
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.
Check the condition of the supply
on (voltage, cabling, fuses, switchgear).
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).
Connect motor cable.
Try other autophasing modes (see
on page parameter 21.13 Autophasing
possible.
If the Turning with Z-pulse
selected, check the zero pulse given by
the encoder.
Check that the motor ID run has been
successfully completed.
Clear parameter
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
Motor type.
