Description
Start signal: When Y is 0, stop PID control; when is 1, start PID control
a.) Parameter P is the proportional parameter, acts on the difference between the actual process
value and the target value.
b.) Parameter I is integral parameter, used to remove the offset.
c.) Parameter D is derivative parameter, mainly used to control signal’s changing trend speed.
Each parameter’s reference value: Kp=20 to 100, Ki=5 to 20, Kd=200 to 700, DIFF=100 to 200
