Integral action control:
When MV is limi ted (H/L, DMV) and the integral value has same sign as l imit over, integral action
is stopped.
Velocity → Position conversion:
In Direct mode, MV increases when PV is increased. → MVn = MVn-1 - ∆Mvn
In Reverse mode, MV decreases when PV is i ncreased. → MVn = MVn-1 + ∆MVn
