3.18.1 20-0* Feedback
This parameter group is used to configure the feedback signal for the adjustable frequency drive's Closed-Loop PID
controller. Whether the Adjustable frequency drive is in closed-loop mode or open-loop mode, the feedback signals can also
be shown on the adjustable frequency drive's display, be used to control an adjustable frequency drive analog output, and
be transmitted over various serial communication protocols.

Function:
Up to three different feedback
signals can be used to provide the
feedback signal for the adjustable
frequency drive's PID controller.
This parameter defines which input
will be 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.
