2381 IGBT overload
Cause
Safety circuit signal(s) connected
to connector STO is lost.
No more PFC motors can be
started because they can be in-
terlocked or in the Hand mode.
All the motors in the PFC system
are interlocked.
The motor connected to the drive
is interlocked (unavailable).
The software is not working
properly.
Cause
During backup/restore, commu-
nication is lost between panel/PC
tool and drive.
Drive software is not able to read
the drive rating ID.
Measured offset of output phase
current measurement or differ-
ence between output phase U2
and W2 current measurement is
too great (the values are updated
during current calibration).
Output current exceeded the in-
ternal fault limit.
Load unbalance typically due to
earth fault in motor or motor
cable.
Short-circuit in motor cable(s) or
motor.
Excessive IGBT junction to case
temperature.
What to do
Check safety circuit connections.
Check that there are no interlocked PFC
motors, see parameters: 76.81...76.84. If
all motors are in use, the PFC system is not
adequately dimensioned to handle the de-
mand.
Check that there are no interlocked PFC
motors, see parameters 76.81...76.84.
Motor connected to the drive is interlocked
and thus cannot be started. Remove the
corresponding interlock to start the drive
controlled PFC motor. See parameters
76.81...76.84.
Restart the control unit.
What to do
Request backup or restore again.
Reset the fault or cycle the power to the
drive.
If the fault persists, contact your local ABB
representative.
Try performing the current calibration again.
If the fault persists, contact your local ABB
representative.
Check the motor load, acceleration times,
motor and motor cable, encoder cable and
there are no power factor correction capacit-
ors in motor cable.
Check there are no power factor correction
capacitors or surge absorbers in motor cable
and there is no earth fault in motor or motor
cables.
Check motor and motor cable and there are
no power factor correction capacitors or
surge absorbers in motor cable.
Check motor cable.
