PID Function
The PID function is for PDAN series only.
A-1 PID Parameter
Pr.73 PID Input Select
This parameter composed by “X” & “Y” separated by decimal point, the X value is used to select the PID Set signal
source for PID block, and the Y value is used to select the PID FB signal source for PID block.
The equivalent source for selection value “X” or “Y” is:

A-2 Digital Input Function
DIx
Function
Description
50
PID Enable
If DIx(50) = OFF, PID block disabled.
If DIx(50) = ON, PID block enabled.
51
PID Hold
If DIx(51) = OFF, PID Integrator normal.
If DIx(51) = ON, PID Integrator Hold.
52
PID Clear
If DIx(52) = ON, PID Integrator Clear.
53
PID Preset
If DIx(53) = ON, PID Integrator preset to the value defined by Pr.74
54
PID Bias Enable
If DIx(54) = ON, Bias = Bias Input Enable.
If DIx(54)=OFF, Bias = 0
55
PID Boost Enable If DIx(55) = ON, Boost = Pr.29 (0.0~500.0%)
If DIx(55) = OFF, Boost = 100.0%.
when DIx(55) = ON, PID output will hold on original value, it is
similar to DIx(51)
