Fault tracing 541
Auxiliary codes for line-side converter faults
The table below lists the auxiliary codes of
. 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:
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
) 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.
