Code
(hex)
Warning / Aux. code Cause What to do
64FF Fault reset A fault has been reset
from the panel, Drive
composer PC tool,
fieldbus or I/O.
Event. Informative only.
A2B1 Overcurrent 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.
Check motor load.
Check acceleration times in
parameter group 23 Speed reference
ramp (speed control) or 28 Frequency
reference chain (frequency control).
Also check parameters 46.01 Speed
scaling, 46.02 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
Checking the
insulation of the assembly on
page 16.
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.
A2B3 Earth leakage 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. See
Checking the
insulation of the assembly on
page 16. 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.
