Fault tracing 365
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 63 ).
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.
4000
Motor cable overload
Calculated motor cable
temperature has exceeded
warning limit. Check the settings of parameters 35.61
and 35.62 .
Check the dimensioning of the motor
cable in regard to required load.
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.
4290 Cooling Drive module temperature is
excessive. Check ambient temperature. If it exceeds
40 °C, ensure that load current does not
exceed derated load capacity of drive.
See appropriate
Hardware manual.
Check drive module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
drive module for dust pick-up. Clean
whenever necessary.
