Cause
Measured offset of output
phase current measurement or
difference between output
phase U2 and W2 current
measurement is too great (the
values are updated during
current calibration).
Output current has exceeded
internal fault limit.
What to do
Try performing the current calibration
again (select Current measurement
calibration at parameter 99.13). If the
fault persists, contact your local ABB
representative.
Check motor load.
If the control unit is externally powered,
check the setting of parameter
Control board supply.
Check acceleration times in parameter
group 23 Speed reference ramp
control), 26 Torque reference chain
(torque control) or 28 Frequency
reference chain (frequency control). Also
check parameters 46.01 Speed
46.02 Frequency scaling and
Torque scaling.
Check motor and motor cable (including
phasing and delta/star connection).
Check there are no contactors opening
and closing in motor cable.
Check that the start-up data in parameter
group 99 corresponds to the motor rating
plate.
Check that there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check encoder cable (including
phasing).
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected inverter
modules, "Y YY" specifies through which
BCU control unit channel the fault was
received. "ZZ" indicates the phase that
triggered the fault (0: No detailed
information available, 1: U-phase, 2: V-
phase, 4: W-phase, 3/5/6/7: multiple
phases).
