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 Figure 6.15 ) are
clamped whereas a feedback above or below is not.

Feedback

The endpoints P1 and P2 are defined by the following parameters, depending on which analog or pulse input is used
Analog 53
S201=OFF Analog 53
S201=ON Analog 54
S202=OFF Analog 54
S202=ON Pulse Input 29 Pulse Input 33
