Fault tracing 343
2340
Short circuit
Short-circuit in motor cable(s)
or motor.
Aux code 0x0080 indicates
that the state feedback from
output phases does not match
the control signals.
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
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
Cross connection
Programmable 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
).
Check that the supply voltage matches
the nominal input voltage of the drive.
Check the supply line for static or
transient overvoltage.
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.
3385
Autophasing
Autophasing routine (see
section
on page
has failed.
Check that the motor ID run has been
successfully completed.
Check that the motor is not already
turning when the autophasing routine
starts.
Check the setting of parameter
.
3381
Output phase loss
Programmable fault:
Motor circuit fault due to
missing motor connection (any
of the three phases not
connected).
In scalar control mode, the
drive detects fault only when
the output frequency is above
10% of the motor nominal
frequency.
Connect motor cable.
If the drive is in scalar mode and nominal
current of the motor is less than 1/6 of the
nominal output current of the drive, set
parameter
to
