3.15 Main Menu - FC Closed Loop - Group
20
This parameter group is used for configuring the closed
loop PID Controller, that controls the output frequency of
the frequency converter.
3.15.1 20-0* 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.

Option:
Function:
Up to three different feedback
signals can be used to provide the
feedback signal for the frequency
converter’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.
