An option board has been removed from its slot, making the device unavailable to the drive. This indicates a configuration change where a previously installed board is no longer present. The drive needs to acknowledge this change to clear the fault status.
Click steps to track your progress.
Power down the drive completely and verify zero voltage on DC bus terminals.
Open the drive enclosure and inspect all option board slots for the presence of a board.
If an option board is missing, reinstall the correct board into its designated slot.
Verify the secure seating of the option board by checking retaining clips or screws.
Power up the drive and confirm the fault clears. If not, check parameter P7-01 for board configuration.
If the board is intentionally removed, update parameter P7-01 (or equivalent) to "0" (No option board) and save parameters.
