Warning
Cause
What to do
A2A1
Current calibration
Current offset and gain
measurement calibration will
occur at next start.
Informative warning. (See parameter
.)
A2B1
Overcurrent
Output current has exceeded
internal fault limit.
Check motor load.
Check acceleration times in parameter
group
(speed
control),
(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 (

A2B3
Earth leakage
Programmable fault:
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
Try running the motor in scalar control
mode if allowed. (See parameter
.)
If no earth fault can be detected, contact
your local ABB representative.
A2B4
Short circuit
Short-circuit in motor cable(s)
or motor.
Check motor and motor cable for cabling
errors.
Check there are no power factor
correction capacitors or surge absorbers
in motor cable.
