Cause
Power unit power supply
failure.
Measurement circuit fault.
Number of connected power
modules differs from expected.
Number of inverter modules
detected does not match the
value of parameter 95.13
Reduced run mode.
State feedback from output
phases does not match control
signals.
Incorrect parameter setting.
The charging switch and DC
switch were operated out of
sequence, or a start command
was issued before the unit was
ready.
Charging circuit fault.
Unidentified power unit logic
fault.
Internal error.

What to do
Check the auxiliary code (format
ZZZY YYXX). "YY Y" specifies the
affected inverter module (0...C, always 0
for ZCU control units). "XX" specifies the
affected power supply (1: Power supply
1, 2: Power supply 2, 3: both supplies).
Contact your local ABB representative,
quoting the auxiliary code.
Check setting of 95.31 Parallel
connection rating id. Cycle the power to
the drive. If the control unit is externally
powered, also reboot the control unit
(using parameter 96.08 Control board
boot) or by cycling its power.
If the problem persists, contact your local
ABB representative.
Check that the value of
run mode corresponds to the number of
inverter modules present. Check that the
modules present are powered from the
DC bus and connected by fiber optic
cables to the BCU control unit.If all
modules of the inverter unit are in fact
available (eg. maintenance work has
been completed), check that parameter
95.13 is set to 0 (reduced run function
disabled).
Contact your local ABB representative,
quoting the auxiliary code.
Check the setting of 95.09 Switch fuse
controller. The parameter should be
enabled only if an xSFC charging
controller is installed.
The normal power-up sequence is:
1. Close charging switch.
2. After charging finishes (charging OK
lamp lights), close DC switch.
3. Open charging switch.
Check the charging circuit.
With a frame R6i/R7i inverter module, the
auxiliary code "FA" indicates that the
charging contactor status feedback does
not match the control signal.
With parallel-connected frame R8i
modules, the auxiliary code (format
XX00), "XX" specifies the affected BCU
control unit channel.
Check power unit logic and firmware
compatibility.
