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 Reduced run mode is set to 0
(reduced run function disabled).

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

BCU control unit channel.
• Check the wiring and condition of
brake resistor.
Check power unit logic and firmware
compatibility.
