Description
：
Start signal
（
Y
）：
When Y is 0, close PID control; when being 1, start PID control
Parameter
P：
proportion parameter, mainly reflect system’s difference,
control as soon as difference
occurs to
decrease this difference.
Parameter
I：
Integral parameter, mainly used to remove the whisht and improve the system’s no
difference degree
Parameter
D：
differential parameter, mainly control signal’s changing trend and decrease the system’s
shake.
Temp. control bound
Diff ：
in the assigned bound, carry on PID control, beyond that bound, no PID
control
Each parameter’s reference value
：
Kp=20~100
；
Ki=5~20
；
Kd=200~700
；
DIFF=100~200

Every input of expansion has option of filter, set via
special FLASH data register FD in PLC.
