AF85 Line side unit
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.
The voltage of the intermediate
DC circuit has not yet risen to
operating level.
warning. For
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 95.01 Supply
voltage is set according to the supply
voltage in use.
Check supply and fuses.
Check that parameter 95.01 Supply
voltage is set according to the supply
voltage in use.
Check the input voltage setting in
parameter 95.01 Supply voltage.
Check the input voltage.
If the problem persists, contact your local
ABB representative.
