Vacuum chiller ladder logic program11/8/2022 ![]() ![]() The simplest way to tune a PID controller is to use its auto-tune feature. This impacts productivity by making operators wait, reduces yield, and increases premature failures when products are processed at the wrong temperature. ![]() When poorly tuned, the temperature can oscillate around the setpoint, be slow to respond to changes, or overshoot the setpoint excessively at start-up or the when the setpoint changes. The controller cannot know the best values for these parameters until it is tuned because every system is different. Consult the manual to find the PID settings in your controller. The exact names of the PID settings depend on the controller manufacturer, but they typically are: proportional band or gain, integral or reset, and derivative or rate. The controller captures what it learns in its PID settings. Tuning teaches the controller the characteristics of a particular system. Why tune controllers?įor optimal results, a PID controller needs to know how much to adjust the heat to achieve a desired temperature change, and how long the temperature takes to react to a change in heater power. Please be careful to consider the unique circumstances of your application as you implement any changes. Bear in mind, though, that controllers vary and applications vary, and we would be remiss if we lead you to believe that our experiences cover all cases or that our advice never goes wrong. We’ve done our best to avoid unnecessary jargon while providing basic terminology and definitions that will be helpful when referencing controller manuals and other sources. This discussion is intended to help explain how these controllers work and to offer some basic guidance on dealing with a PID temperature controller.
