Auxiliary Codes For Line-Side Converter Warnings - ABB ACS880 Firmware Manual

Auxiliary codes for line-side converter warnings

The table below lists the auxiliary codes of
advanced troubleshooting, see the firmware manual of the line converter.
Code Event name /
(hex) Aux. code
AE01 Overcurrent
AE02 Earth leakage
AE04 IGBT overload
AE05 BU current
difference
AE06 BU earth
leakage
AE09 DC link
overvoltage
AE0A DC link
undervoltage
Cause
Output current has exceeded internal
fault limit.
IGBT supply has detected load
unbalance.
Excessive IGBT junction to case
temperature.
Current difference detected by the
branching unit (BU).
Earth leakage detected by the
branching unit: sum of all currents
exceeds the level.
Excessive intermediate circuit DC
voltage.
Note: This warning can be shown only
when the IGBT supply unit is not
modulating.
Intermediate circuit DC voltage is not
sufficient due to missing phase in
supply voltage, blown fuse or rectifier
bridge internal fault.
Note: This warning can be shown only
when the IGBT supply unit is not
modulating.
AF85 Line side unit
What to do
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.
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.
Check supply cable.
Check converter fuses.
Check converter(s).
Check inverter(s).
Check LCL filter.
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.
Check that parameter
voltage is set according to the supply
voltage in use.
Check supply and fuses.
Check that parameter
voltage is set according to the supply
voltage in use.
