ABB ACS880 N5700 Series - Auxiliary Codes for Line-Side Converter Warnings

Auxiliary codes for line-side converter warnings
The table below lists the auxiliary codes of AF85 Line side unit warning. For
advanced troubleshooting, see the firmware manual of the line converter.
What to doCause
Event name /
Aux. code
Code
(hex)
Check supply voltage.Output current has exceeded internal
fault limit.
OvercurrentAE01
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 has detected load
unbalance.
Earth leakageAE02
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.Excessive IGBT junction to case
temperature.
IGBT overloadAE04
Check converter fuses.Current difference detected by the
branching unit (BU).
BU current
difference
AE05
Check converter(s).
Check inverter(s).
Check LCL filter.
Check AC fuses.Earth leakage detected by the
branching unit: sum of all currents
exceeds the level.
BU earth
leakage
AE06
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 95.1 Supply
voltage is set according to the supply
voltage in use.
Excessive intermediate circuit DC
voltage.
Note: This warning can be shown only
when the IGBT supply unit is not
modulating.
DC link
overvoltage
AE09
Check supply and fuses.Intermediate circuit DC voltage is not
sufficient due to missing phase in
DC link
undervoltage
AE0A
Check that parameter 95.1 Supply
voltage is set according to the supply
voltage in use.
supply voltage, blown fuse or rectifier
bridge internal fault.
Note: This warning can be shown only
when the IGBT supply unit is not
modulating.
