control

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

Gap (dead-band) operation:
