EARTH FAULT
(0x2330)
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.
If no earth fault can be detected, contact
your local ABB representative.
2040
AUTORESET
(0x6080)
A fault is to be autoreset.
Informative alarm. See parameter group
2041
MOTOR NOM VALUE
(0x6383)
The motor configuration
parameters are set incorrectly.
Check the settings of the motor
configuration parameters in group 99.
The drive is not dimensioned
correctly.
Check that the drive is sized correctly for
the motor.
2042
D2D CONFIG
(0x7583)
The settings of drive-to-drive
link configuration parameters
(group 57) are incompatible.
Check the settings of the parameters in
group
.
2043
STALL
(0x7121)
Programmable fault:
Motor is operating in stall
region because of e.g.
excessive load or insufficient
motor power.
Check motor load and drive ratings.
Check fault function parameters.
2044
LCURVE
(0x2312)
Programmable fault:
/
Overload or underload limit
has been exceeded.
Check the settings of the parameters in
group
2045
LCURVE PAR
(0x6320)
The load curve has been
incorrectly or inconsistently
defined.
Check the settings of the parameters in
group
2046
FLUX REF PAR
(0x6320)
The
U/f
(voltage/frequency)
curve has been incorrectly or
inconsistently defined.
Check the settings of the parameters in
group
.
2047
SPEED FEEDBACK
(0x8480)
No speed feedback is
received.
Check the settings of the parameters in
group
Check encoder installation. See the
description of fault
for more
information.
2048
OPTION COMM
LOSS
(0x7000)
Communication between drive
and option module (FEN-xx
and/or FIO-xx) is lost.
Check that option modules are properly
connected to Slot 1 and (or) Slot 2.
Check that option modules or Slot 1/2
connectors are not damaged. To
determine whether module or connector
is damaged: Test each module
individually in Slot 1 and Slot 2.
