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 frequency
converter automatically sets this parameter to Option A [3] if it
detects a valid fieldbus option installed in slot A. If the option is
removed, the frequency converter detects a change in the config-
uration, sets 8-02 Control Word Source back to default setting
RS-485, and the frequency converterr then trips. If an option is
installed after initial power-up, the setting of 8-02 Control Word
Source will not change but the frequency converter 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.
