Fiaz Posted January 2, 2022 Report Share Posted January 2, 2022 Hi, I am playing with PID Unitronic V700 controller to regulate heater furnace for my laboratory reactor. It is getting overshoot by 30 C. Can anyone help in tuning ? Quote Link to comment Share on other sites More sharing options...
MVP 2021 kratmel Posted January 2, 2022 MVP 2021 Report Share Posted January 2, 2022 There are many topics about PID present on forum. Try to search on forum. Please post your furnance setup: hardware, sensor installation, heat source, ON-OFF slow PWM or fast PWM output used, temperature range. If you use Autotuning - please try to set lower (-30 C) setpoint and start Autotuning. Fix on paper P, I, D settings. Then start Autotuning on normal setpoint. You can see what changes appear in P, I, D and understand system behavior with different settings. Quote Link to comment Share on other sites More sharing options...

Furnace heater and heat source is - Ceramic Band Heater Ø110x300 mm (H) V230 2300W W1150x2 Thermocouple type K Intended temperature range is 250-350 C I need to ask about slow or Fast PWM I am a novice in this area, I will get back to you with the missing information.
