Troubleshooting guide 193
Fault message
Cause
What to do
DSP watchdog
Internal system error
Reset the inverter by switching off and
on the power. If the problem persists,
contact your ABB representative. The
controller card must probably be
replaced or the controller software
upgraded.
SPI Timeout
Power supply fault
Internal system error
Reset the inverter by switching off and
on the power. If the problem persists,
contact your ABB representative. The
controller card must probably be
replaced.
Preload
time-out
The
DC
capacitors
could
not be charged.
−
Measure the three line voltages and
check if they are within limits.
−
Verify the fuses (PF1 and PF2) and the
resistors (R1 and R2) of the preload
circuit (A001).
−
Inspect the DC-bus for traces of
damage that may have caused a short
circuit on the DC-side of the IGBT-
module or on the DC voltage
measurement board.
Com. Problem (CAN
Bus)
The communication
through the CAN bus
between units is not
working properly.
−
Check the RJ-45 cables between
modules.
−
Check the termination for the CAN
bus: both (and only) the ends of the
bus must have the DIP switch S5-4 in
the “set” status.
−
Reset the inverter by switching off
and on the power. If the problem
persists, contact your ABB
representative. The controller card
must probably be replaced.

Internal system error
Reset the inverter by switching off and
on the power. If the problem persists,
contact your ABB representative. The
controller card must probably be
replaced.
Different firmwares
Different units in a
inverter system have
different firmware version
(DSP or microcontroller)
Upgrade all the units with the same
(most recent) firmware. In the ESI-
Manager menu, go to “About ESI\Code
update” item.
