Check the auxiliary code. Check the
source of the fault corresponding to the
code:
1: Phase A
2: Phase B
4: Phase C
8: Phase cannot be detected Check the
AC fuses.
Check for input power supply imbalance.
Input phase loss detected by the IGBT
bridge.

Check that parameter 95.1 Supply
voltage is set according to the supply
voltage in use.
Excessive intermediate circuit DC
voltage.
DC link
overvoltage
3E04
Check supply cabling, fuses and
switchgear.
Check that parameter 95.1 Supply
voltage is set according to the supply
voltage in use.
Intermediate circuit DC voltage is not
sufficient because of a missing supply
phase or blown fuse.
DC link
undervoltage
3E05
Check the DC fuses.
Check the connection to the DC bus.
If the problem persists, contact your local
ABB representative.
Difference in DC voltages between
parallel-connected supply modules.
BU DC link
difference
3E06
Check the supply network connections.
Check the AC fuses.
If the problem persists, contact your local
ABB representative.
Difference in main voltages between
parallel-connected supply modules.
BU voltage

3E07
Check parameter 95.1 Supply voltage.
Check supply voltage and fuses.
Check the connection from the relay
output to the charging contactor.
Check that the DC voltage measuring
circuit is working correctly.
DC link voltage is not high enough after
charging.

Check ambient temperature. If it exceeds
40 °C (104 °F), ensure that load current
does not exceed derated load capacity.
See appropriate hardware manual.
Check power module cooling air flow and
fan operation.
Check inside of cabinet and heatsink of
power module for dust pick-up. Clean
whenever necessary.
Power module temperature is excessive.Cooling4E01
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT supply
unit power.
