Title: Do-more PID loop
Post by: antonio78 on November 29, 2012, 09:50:01 PM

Does anyone know how to make my encoder feed back (RPM) to be my PV on my PID. I get a number that does not match the number I get back from the encoder card

Are you scaling it in the PID instruction or SCALE instruction, or are you just doing a MOVE into the loop's .PV structure member?
