This parameter cannot be adjusted while

Select the source of the control word: one of

two serial interfaces or four installed options.

During initial power-up, the frequency converter

automatically sets this parameter to [3] Option A

if it detects a valid fieldbus option module

installed in slot A. If the option is removed, the

frequency converter detects a change in the

configuration, sets O-02 Control Word Source

back to default setting RS-485, and the

frequency converter trips. If an option is

installed after initial power-up, the setting of

O-02 Control Word Source does not change, but

the frequency converter trips and displays:

Alarm 67 Option Changed.

When retrofitting a bus option into a frequency

converter, that did not have a bus option

installed to begin with, take an ACTIVE decision

to move the control to Bus based. This is done

for safety reasons to avoid an accidental

change.
