Cause
Input phase loss detected by the IGBT
bridge.
Excessive intermediate circuit DC
voltage.
Intermediate circuit DC voltage is not
sufficient because of a missing supply
phase or blown fuse.
Difference in DC voltages between
parallel-connected supply modules.
Difference in main voltages between
parallel-connected supply modules.
DC link voltage is not high enough
after charging.
Power module temperature is
excessive.
IGBT temperature is excessive.
Power unit module temperature is
excessive.
Fault tracing 701
What to do
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.
Check that parameter
voltage is set according to the supply
voltage in use.
Check supply cabling, fuses and
switchgear.
Check that parameter
voltage is set according to the supply
voltage in use.
Check the DC fuses.
Check the connection to the DC bus.
If the problem persists, contact your
local ABB representative.
Check the supply network
connections.
Check the AC fuses.
If the problem persists, contact your
local ABB representative.
Check parameter 95.1 Supply
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.
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.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against IGBT
supply unit power.
