Chapter 15 PID Function (Built-in function)
15 - 17
(r) PV Follow-up setting
It is intended to prevent any excessive operation of a drive resulting from sudden change of
output at the initial control and changes SV gradually from PV at the time when PID operation
starts, not directly to SV in case control just turns from stop to operation mode or it changes from
manual to automatic operation. At the moment, SV represents the frequency of PID operation
cycles taken from when control starts to when it reaches to the set SV (other operations are same
as SV ramp function). The available scope is between 0 ~ 65,535. If SV is changed again while
PV follow-up is in operation, the SV would be also changed according to SV ramp.
(s) Min./max. PV
It sets the min./max. value entered as the present value of PID control. The available scope is
between -32,768 ~ 32,767.
