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.

Loop Mode or Open Loop Mode, the feedback signals can
be shown on the frequency converter's display. It can also
be used to control a frequency converter analog output,
and be transmitted over various serial communication
protocols.
