Figure 49: Clamping of Reference Input with Limits inside Minimum to Maximum
Case 2: Positive reference with dead band, digital input to trigger reverse, part II
Figure 50
shows how reference input with limits outside -maximum to +maximum limits clamps to the input low and high limits before
adding to external reference, and how the external reference is clamped to -maximum to +maximum by the reference algorithm.
