ABB ACS880-17 - Auxiliary Codes for Line-Side Converter Faults

Fault tracing 541
Auxiliary codes for line-side converter faults
The table below lists the auxiliary codes of 7583 Line side unit faulted. For advanced
troubleshooting, see the firmware manual of the line converter.
Code
(hex)
Fault / Aux. code Cause What to do
2E00 Overcurrent Output current has exceeded
internal fault limit.
Check supply voltage.
Check that there are no power factor
correction capacitors or surge absorbers
in supply cable.
Check motor load and acceleration
times.
Check power semiconductors (IGBTs)
and current transducers.
2E01 Earth leakage
Programmable fault:
31.120 LSU earth fault
IGBT supply unit has detected
an earth fault.
Check AC fuses.
Check for earth leakages.
Check supply cabling.
Check power modules.
Check there are no power factor
correction capacitors or surge absorbers
in supply cable.
If no earth fault can be detected, contact
your local ABB representative.
2E02 Short circuit IGBT supply unit has detected
short circuit.
Check supply cable.
Check there are no power factor
correction capacitors or surge absorbers
in supply cable.
After correcting the cause of the fault,
reboot the control unit (using parameter
96.08 Control board boot) or by cycling
power.
2E04 IGBT overload Excessive IGBT junction to
case temperature.
Check the load.
2E05 BU current difference Current difference detected by
the branching unit (BU).
Check converter fuses.
Check converter(s).
Check inverter(s).
Check LCL filter.
Power off all boards.
If the fault persists, contact your local
ABB representative.
2E06 BU earth leakage Earth leakage detected by the
branching unit: sum of all
currents exceeds the level.
Check AC fuses.
Check for earth leakages.
Check supply cabling.
Check power modules.
Check there are no power factor
correction capacitors or surge absorbers
in supply cable.
If no earth fault can be detected, contact
your local ABB representative.
