3E00 Input phase loss
Programmable fault:
31.121 LSU supply phase
loss
Input phase loss detected by
the IGBT bridge.
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.
3E04 DC link overvoltage Excessive intermediate circuit
DC voltage.
Check that parameter 95.01 Supply
voltage is set according to the supply
voltage in use.
3E05 DC link undervoltage Intermediate circuit DC voltage
is not sufficient because of a
missing supply phase or blown
fuse.
Check supply cabling, fuses and
switchgear.
Check that parameter 95.01 Supply
voltage is set according to the supply
voltage in use.
3E06 BU DC link difference Difference in DC voltages
between parallel-connected
supply modules.
Check the DC fuses.
Check the connection to the DC bus.
If the problem persists, contact your local
ABB representative.
3E07 BU voltage difference Difference in main voltages
between parallel-connected
supply modules.
Check the supply network connections.
Check the AC fuses.
If the problem persists, contact your local
ABB representative.
3E08 LSU charging DC link voltage is not high
enough after charging.
Check parameter 95.01 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.
4E01 Cooling Power module temperature is
excessive.
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.
4E02 IGBT temperature IGBT temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT supply
unit power.
4E03 Excess temperature Power unit module
temperature is excessive.
See AE14 Excess temperature (page
540).
4E04 Excess temperature
difference
High temperature difference
between the IGBTs of different
phases. The amount of
available temperatures
depends on the frame size.
See AE15 Excess temperature
difference (page 540).
