8-02 Control Word Source
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 fieldbus option installed in slot A. When the
option is removed, the frequency converter detects a configu-
ration 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
.
When retrofitting a bus option into a frequency 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.
