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
(speed
control) or
(frequency control). Also check
.
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
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 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.
