Select the source of the control word: 1 of 2 serial interfaces or 4 installed options. During initial power-up, the drive automatically sets
this parameter to [3] Option A if it detects a valid fieldbus option installed in slot A. When the option is removed, the drive detects a
configuration change, sets parameter 8-02 Control Word Source to default setting [1] FC RS485, and trips. If an option is installed after
initial power-up, the setting of parameter 8-02 Control Word Source does not change, but the drive trips and shows: Alarm 67, Option
Changed. When retrofitting a bus option into a drive that did not have a bus option installed earlier, change the control to bus-based.
This change is required for safety reasons to avoid an unintended change.
