Select the source of the control word: 1 of 2 serial
interfaces or 4 installed options. During initial
power-up, the frequency converter automatically
sets this parameter to [3] Option A if it detects a
valid
eldbus option installed in slot A. When the
option is removed, the frequency converter detects
a conguration 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 frequency converter trips
and shows alarm 67, Option Changed.

converter 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.
