Fault tracing 539
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.
Code
(hex)
Warning / Aux. code Cause What to do
AE01 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.
AE02 Earth leakage
Programmable warning:
31.120 LSU earth fault
IGBT supply has detected load
unbalance.
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.
AE04 IGBT overload Excessive IGBT junction to
case temperature.
Check supply cable.
AE05 BU current difference Current difference detected by
the branching unit (BU).
Check converter fuses.
Check converter(s).
Check inverter(s).
Check LCL filter.
AE06 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.
AE09 DC link overvoltage Excessive intermediate circuit
DC voltage.
Note: This warning can be
shown only when the IGBT
supply unit is not modulating.
Check that parameter 95.01 Supply
voltage is set according to the supply
voltage in use.
AE0A DC link undervoltage 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.
Check supply and fuses.
Check that parameter 95.01 Supply
voltage is set according to the supply
voltage in use.
AE0B DC not charged The voltage of the intermediate
DC circuit has not yet risen to
operating level.
Check the input voltage setting in
parameter 95.01 Supply voltage.
Check the input voltage.
If the problem persists, contact your local
ABB representative.
