Fault tracing 539
Auxiliary codes for line-side converter warnings
The table below lists the auxiliary codes of
. 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:
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
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
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
.
Check the input voltage.
If the problem persists, contact your local
ABB representative.
