Cause
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.
Total earth leakage of inverter
modules is excessive.
Intermediate circuit DC voltage
is oscillating due to missing input
power line phase or blown fuse.
Incorrect input power and motor
cable connection.
Excessive intermediate circuit
DC voltage.
Intermediate circuit DC voltage
is not sufficient.
Difference in DC voltages
between parallel-connected in-
verter modules.

What to do
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.
Check there are no power factor correction
capacitors or surge absorbers in motor
cable.
Measure insulation resistances of motor
cables and motor.
Contact your local ABB representative.
Check input power line fuses and there is
no input power supply imbalance.
Check input power connections.
Check overvoltage control is on, supply
voltage matches the nominal input voltage
of the drive. Check supply line for static or
transient overvoltage, brake chopper, brake
resistor and deceleration time. Use coast-
to-stop function (if applicable).
Check supply cabling, fuses and 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).
