Scaling Of Analog And Pulse References And Feedback - GE AF-650 GP Design And Installation Manual

Application Set-Up Examples
6.4.5 Scaling of Analog and Pulse
References and Feedback
References and feedback are scaled from analog and pulse
inputs in the same way. The only difference is that a
reference above or below the specified minimum and
maximum "endpoints" (P1 and P2 in Illustration 6.15) are
clamped whereas feedback above or below is not.
