3.13.1 20-0* Feedback
20-00 Feedback 1 Source
Up to 3 different feedback signals can be used to provide the
feedback signal for the frequency converter’s PID controller.
This parameter defines which input is used as the source of the
first feedback signal.
Analog input X30/11 and analog input X30/12 refer to inputs on
the optional General Purpose I/O board.
