The following is a block diagram overview of the position follower mode:
Speed Reference Selection
For the position following mode to work properly, there needs to be a feed
forward speed reference for the speed loop of the drive to follow.
For example, to follow Encoder 1, link parameter 12 [Speed Ref 2] to parameter
241 [Encdr1 Spd Fdbk]. Set parameter 27 [Speed Ref A Sel] = 2 “Speed Ref 2.”
When a gear ratio is used in the position loop, parameter 13 [Spd Ref2 Multi]
must be setup to match the gear ratio set in the position loop.
