Heating/Cooling PID Control
If heating/cooling PID control is used, you can set PID control separately for heating and cooling.
The PID constants for both heating and cooling can be automatically set according to the cooling
control characteristics by setting the Heating/Cooling Tuning Method parameter and then performing
autotuning (AT).
*
The unit is determined by the setting of the Integral/Derivative Time Unit parameter. The Proportional Band
(Cooling), Integral Time (Cooling), and Derivative Time (Cooling) parameters are initialized if the
Integral/Derivative Time Unit parameter is changed.
Air Cooling/Water Cooling Tuning
Control that is suitable for an application that does not have linear cooling characteristics (such as
plastic molding machines) is performed. The response is fast and the response characteristics are
stable.
Linear Tuning
Control that is suitable for an application that has linear cooling characteristics is performed.
