Temperature control
functions
Description
ON/OFF (2-position)
control
Switches output control ON/OFF according to the SV/PV magnitude relationship.
Control systems can be built from simple elements such as SSR. This is appropriate
for situations where high accuracy is not required.
PID control
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 control
Reduces the amount of overshoot during control. It is effective when you want to
suppress overshoot while changing SV, even during processes where it may take a
long time to reach the target value.
Self tuning control
Adds controls while automatically calculating PID to meet the control target or
changing SV. It is effective when the control conditions change frequently.
PID2 control
Suppresses the amount of overshoot during control for processes that turn the control
target off and then on again. It is effective when the control target turns on and off
while power ows continuously to the temperature controller.
You can set the temperature control function in the parameter [CtRL] (see page 36).
