Anti-reset wind up
[Description]
• This setting is not require unless it
is necessary.
This function is used to suppress
over-shoot.
• Anti-reset wind up (Ar) is automati-
cally set in optimum value by P.I.D
auto-tuning.
The value of over-shoot can be con-
trolled by setting BAL.
• By setting anti-reset wind up (Ar)
in optimum value, unwanted integral
action can be cut and over-shoot is
reduces.
(Note) This controller has fuzzy con-
trol function, so over-shoot
can be minimized without us-
ing BAL and Ar. This param-
eter is used only for inter-
changeability with former
type (PYZ series).
