relationship of PV and SV Can build a control system
out of simple elements such as SSR. Suitable when
accuracy is not requested.
PID Controls
PID calculation and controls proceed according to the
previously set PID parameters.
PID parameters can be set manually or through auto-
tuning (AT).
It is the most basic control in this equipment.
Fuzzy PID Control
PID control with function that reduces the amount of
overshoot during control. It is effective when you want
to suppress overshoot when SV is changed, even if you
may take a long time to reach the target value.
Self-tuning Control
Automatically calculating PID control according to the
control target or SV change. It is effective when the
control conditions change frequently.
PID2 Control
In case which the power supply of the control target
goes ON → OFF → ON, this PID2 control can suppress
the amount of overshoot during control target turns OFF
→ ON.
