8-02 Control Word Source
This parameter cannot be adjusted while the motor is running.
Select the source of the control word: One of 2 serial interfaces
or 4 installed options. During initial power-up, the unit automat-
ically sets this parameter to [3] Option Aif it detects a valid
Fieldbus option installed in slot A. If the option is removed, the
unit detects a change in the configuration, sets
parameter 8-02 Control Word Source back to default setting [1] FC
RS485, and the unit then trips. If an option is installed after initial
power-up, the setting of parameter 8-02 Control Word Source does
not change but the unit trips and displays: Alarm 67 Option
Changed.
When retrofitting a bus option into a unit that did not have a
bus option installed to begin with, move the control to bus
based. This is done for safety reasons to avoid an accidental
change.
