Variable Frequency Drive Fault Codes; (Optional) - Trane Arctic Manhattan Gen II Installation, Operation And Maintenance Manual

Variable Frequency Drive Fault
Codes (Optional)
The following table lists the faults by code number and
describes each.
Warnings and faults indicate an abnormal drive status.
The codes and names of active warnings and faults are
displayed on the control panel of the drive as well as in
the Drive composer PC tool. Only the codes of
warnings and faults are available over fieldbus.
Warnings do not need to be reset; they stop showing
when the cause of the warning ceases. Warnings do

not latch and the drive will continue to operate the
motor.
Faults latch inside the drive and cause the drive to trip,
and the motor stops. After the cause of a fault has been
removed, the fault can be reset from the panel or from
a selectable source (parameter 31.11 Fault reset
selection) such as the digital inputs of the drive.
Reseting the fault creates an event 64FF Fault reset.
After the reset, the drive can be restarted.
Note that some faults require a reboot of the control
unit either by switching the power off and on, or using
parameter 96.08 Control board boot – this is mentioned
in the fault listing wherever appropriate.
Cause
Panel or PC tool has failed to
communicate with the drive when
backup was being made or restored.
Drive software has not been able to
read the rating ID of the drive.
Output current has exceeded internal
fault limit.
In addition to an actual overcurrent
situation, this fault may also be
caused by an earth fault or supply
phase loss.
Drive has detected load unbalance
typically due to earth fault in motor or
motor cable.

What to do
Request backup or restore again.
Reset the fault to make the drive try
to reread the rating ID.
If the fault reappears, cycle the
power to the drive. You may have to
be repeat this. If the fault persists,
contact your local ABB
representative.
Check motor load.
Check acceleration times in
parameter group 23 Speed reference
ramp (speed control), 26 Torque
reference chain (torque 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 there are no contactors
opening and closing in motor cable.
Check that the start-up data in
parameter group 99 corresponds to
the motor rating plate.
Check that 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.
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.
Try running the motor in scalar
control mode if allowed. (See
parameter 99.04 Motor control
mode.)
If no earth fault can be detected,
contact your local ABB
representative.
