Calibration
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).
Try performing the current calibration
again (select
). If the
fault persists, contact your local ABB
representative.

Overcurrent
Output current has exceeded
internal fault limit.
Check motor load.
If the control unit is externally powered,
check the setting of parameter
.
Check acceleration times in parameter
group
(speed
(torque control) or
(frequency control). Also
,
.
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 (
