3.18 Main Menu - Adjustable Frequency Drive Closed-loop - Group 20
3.18.1 20-** Adjustable Frequency Drive Closed-loop
This parameter group is used for configuring the closed-loop PID controller, that controls the output frequency of the adjustable frequency drive.
3.18.2 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.
