Warning messages

Note: The list also contains events that only appear in the Event log.
Code
Warning / Aux. code
(hex)
64FF Fault reset
A2A1 Current calibration
A2B1 Overcurrent
A2B3 Earth leakage
Cause
A fault has been reset from the
panel, Drive composer PC tool,
fieldbus or I/O.
Current offset and gain
measurement calibration will
occur at next start.
Output current has exceeded
internal fault limit.
In addition to an actual
overcurrent situation, this
warning may also be caused
by an earth fault or supply
phase loss.
Drive has detected load
unbalance typically due to
earth fault in motor or motor
cable.
What to do
Event. Informative only.
Informative warning. (See parameter
99.13 ID run requested.)
Check motor load.
Check acceleration times in parameter
group 23 Speed reference ramp
control), 28 Frequency reference chain
(frequency control). Also check
parameters 46.01 Speed
Frequency scaling and 46.03 Torque
scaling.
Check motor and motor cable (including
phasing and delta/star connection).
Check for an earth fault in motor or motor
cables by measuring the insulation
resistances of motor and motor cable.
See chapter Electrical installation,
section Checking the insulation of the
assembly in the Hardware manual of the
drive.
Check there are no contactors opening
and closing in motor cable.
Check that the start-up data in parameter
group 99 Motor data corresponds to the
motor rating plate.
Check that there are no power factor
correction capacitors or surge absorbers
in 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.
See chapter Electrical installation,
section Checking the insulation of the
assembly in the Hardware manual of the
drive. If an earth fault is found, fix or
change the motor cable and/or motor.
If no earth fault can be detected, contact
your local ABB representative.
