The option card installed in port CN5-C has been
changed while operating.
Turn the control power off and reconnect the option card. Check if the option card is properly
plugged into the option port.
The option card connection to port CN5-B is
faulty.
Try to use the card in a different option port (in case of a PG option, use port CN5-B). If the
option card works properly in a different option port, CN5-C is damaged, and the drive requires
replacement. If the error persists (oFA01 or oFb01 occur), replace the option card.
