NOTICE
This parameter cannot be adjusted
while the motor is running.
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. If the option is removed, the
frequency converter detects a change in the
configuration, sets parameter 8-02 Control
Source to default setting [1] FC Port, and the
frequency converter then trips. If an option is
installed after initial power-up, the setting of
parameter 8-02 Control Source does not
change, but the frequency converter trips and
shows alarm 67, Option Changed.
