3.22 CL-## PID Closed Loop
This parameter group is used for configuring the closed-loop PID controller that controls the output frequency of the
frequency converter.
3.22.1 CL-0# Feedback
This parameter group is used to configure the feedback signal for the frequency converter’s closed-loop PID controller.
Whether the frequency converter is in closed-loop mode or open-loop mode, the feedback signals can also be shown on
the frequency converter’s display, be used to control a frequency converter analog output, and be transmitted over various
serial communication protocols.

If feedback is not used, set its
source to
[0] No Function
.
Parameter CL-20 Feedback Function
determines how the PID controller
uses the 3 possible feedbacks.
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. (OPCGPIO).

Analog Inputs X42/1, X42/3, X42/5 refer
to inputs on the optional analog I/O
board (OPCAIO).
