Description:
Start signal (Y): when Y is 0, close PID control, when be 1 , start PID control
Parameter P: Proportion parameter, mainly reflex system’s difference, carry on control as soon as
difference occurs to improve the system’s no difference degree.
Parameter I:Integral parameter. Mainly used to remove whisht, improve the system’s no difference
degree.
Parameter D:Differential parameter, mainly used to control signal’s changing trend,minish system’s
shake.
Control bound Diff:In the assigned bound, carry on PID control. Beyond the bound, no PID control.
Dead area Death:When the current PID control value compares with the preceding PID control value. If
the difference between them is less than the set dead bound’s value, the module will
abnegate the current PID control value, send the preceding PID control value to the
PLC main unit.
Each parameter’s reference value: Kp=20~100; Ki=5~20; Kd=200~700; DIFF=100~200
