Code
(hex)
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.

3E00
Check that parameter
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
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
difference
3E07
Check parameter
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.
LSU charging
3E08
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.
Cooling
4E01
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT
supply unit power.
IGBT temperature is excessive.
