Cause
The way the control unit is
powered does not correspond
to parameter setting.
Communication errors
detected between the drive
control unit and the power unit.
Connection between the drive
control unit and the power unit
is lost.
Internal communication error.
Measurement circuit fault.
Power unit power supply
failure.
Measurement circuit fault.
State feedback from output
phases does not match control
signals.
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.

What to do
Check setting of 95.04 Control board
supply.
Check the connection between the
control unit and the power unit.
Check the auxiliary code (format XXXY
YYZZ). With parallel-connected modules,
"Y YY" specifies the affected BCU control
unit channel (0: broadcast). "ZZ"
specifies the error source (1: Transmitter
side [link error], 2: Transmitter side [no
communication], 3: Receiver side [link
error], 4: Receiver side [no
communication], 5: Transmitter FIFO
error [see "XXX"], 6: Module [xINT board]
not found, 7: BAMU board not found).
"XXX" specifies the transmitter FIFO
error code (1: Internal error [invalid call
parameter], 2: Internal error
[configuration not supported],
3: Transmission buffer full).
Check the connection between the
control unit and the power unit.
Contact your local ABB representative.
Contact your local ABB representative
quoting the auxiliary code.
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).
Contact your local ABB representative
quoting the auxiliary code.
Contact your local ABB representative
quoting the auxiliary code.
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.
