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.
What to do Cause
Event name /
Aux. code Code
(hex)
Check supply voltage. Output current has exceeded internal
fault limit. Overcurrent 2E00
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.
Check AC fuses. IGBT supply unit has detected an earth
fault. Earth leakage 2E01
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.
Check supply cable. IGBT supply unit has detected short
circuit. Short circuit 2E02
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
96.8 Control board boot or
by cycling power.
Check the load. Excessive IGBT junction to case
temperature. IGBT overload 2E04
Check converter fuses. Current difference detected by the
branching unit (BU). BU current
difference 2E05
Check converter(s).
Check inverter(s).
Check LCL filter.
Power off all boards.
If the fault persists, contact your local
ABB representative.
Check AC fuses. Earth leakage detected by the
branching unit: sum of all currents
exceeds the level. BU earth
leakage 2E06
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.
