316 Fault tracing
2035 PS COMM
(0x5480)
08.07 Alarm word3 b3
Communication errors
detected between the JCU
Control Unit and the power
unit of the drive.
Check the connections between the JCU
Control Unit and the power unit.
2036 RESTORE
(0x6300)
08.07 Alarm word3 b4
Restoration of backed-up
parameters failed.
Contact your local ABB representative.

CALIBRATION
(0x2280)
08.07 Alarm word3 b5
Current measurement
calibration will occur at next
start.
Informative alarm.
2039 EARTH FAULT
(0x2330)
08.07 Alarm word3 b7
Programmable alarm: 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.

A fault is to be autoreset. Informative alarm. See parameter group
32 Automatic reset.
2041 MOTOR NOM VALUE
(0x6383)
08.07 Alarm word3 b9
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.

(0x7121)
08.07 Alarm word3 b11
Programmable alarm: 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)
08.07 Alarm word3 b12
Programmable alarm: 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)
08.07 Alarm word3 b13
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)
08.07 Alarm word3 b14
The U/f (voltage/frequency)
curve has been incorrectly
or inconsistently defined.
Check the settings of the parameters in
group 38 Flux ref.
2048 OPTION COMM LOSS
(0x7000)
08.08 Alarm word4 b0
Communication between
drive and option module
(FEN-xx and/or FIO-xx) is
lost.
Check that option modules are properly
connected to Slot 1 (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.
