PID programing
« on: June 23, 2008, 04:36:53 PM »
I have PIDed the hot air popper (the roaster has to share the PID with the pottery to keep mama happy) it works, it turns on and off the heat element, I programed a simple 300 in 3 minutes, 350 in 1, 375 in 2, 401 in 1, 445 in 5 ramp soak, when I run the program the sv starts to climb from the 300 and not immediately to 350?!?!  I believe I have good values for P,I,and D  I get a good steady climb in temp but not following my profile?!?! 

any weblinks, opinions, ideas and/or pointing of finger and laughing will be humbly excepted
