8-02 Control Word Source
Select the source of the control word: one of two serial interfaces or
four installed options. During initial power-up, the adjustable
frequency drive automatically sets this parameter to Option A [3] if
it detects a valid serial communication option installed in slot A. If
the option is removed, the adjustable frequency drive detects a
change in the configuration, sets 8-02 Control Word Source back to
default setting FC RS-485, and the adjustable frequency drive then
trips. If an option is installed after initial power-up, the setting of
8-02 Control Word Source will not change but the adjustable
frequency drive will trip and display: Alarm 67 Option Changed .
When you retrofit a Bus option into a drive that did not have a Bus
option installed to begin with, you must take an ACTIVE decision to
move the control to Bus-based. This is done for safety reasons in
order to avoid an accidental change.
This parameter cannot be adjusted while the motor is running.
