Danfoss vlt FC 102 Programming Guide

3.18 Parameters: 20-** Main Menu - FC Closed Loop
This parameter group is used for conguring the closed-loop PID controller that controls the output frequency of the
frequency converter.
3.18.1 20-0* Feedback
This parameter group is used to congure 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.
