Fault tracing 295
2039 EARTH FAULT
(0x2330)
Programmable fault:
30.05 Earth 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
32 Automatic reset.
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 57 D2D communication.
2043 STALL
(0x7121)
Programmable fault:
30.09 Stall function
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:
34.01 Overload func /
34.02 Underload func
Overload or underload limit
has been exceeded.
Check the settings of the parameters in
group 34 User load curve.
2045 LCURVE PAR
(0x6320)
The load curve has been
incorrectly or inconsistently
defined.
Check the settings of the parameters in
group 34 User load curve.
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 38 Flux ref.
2047 SPEED FEEDBACK
(0x8480)
No speed feedback is
received.
Check the settings of the parameters in
group 19 Speed calculation.
Check encoder installation. See the
description of fault 0039 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.
