Differential limit

Integral action control:

When MV is limited (H/L, DMV) and the integral value has same sign as limit over, integral action is stopped.

Velocity → Position conversion:		MVn = MVn-1	- ∆ MVn
In Direct mode, MV increases when PV is increased.	→	MVn = MVn-1	- ∆ MVn
In Reverse mode, MV decreases when PV is increased.	→	MVn = MVn-1	+ ∆ MVn
