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
23 Speed reference ramp
group
26 Torque reference
(speed control),
chain
(torque control) or
reference chain
(frequency control).
Also check parameters
scaling 46.02 Frequency scaling
,
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
installation Checking the
, section
insulation of the assembly
hardware manual of the drive.
Check there are no contactors opening
and closing in motor cable.
Check that the start-up data in
99 Motor data
parameter group
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
installation Checking the
, section
insulation of the assembly
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.
