Using Automatic Selection of PID Sets by Zone
Setting Example
In this example, automatic selection is specified for program 0 and then settings are made to automati-
cally select PID sets 1 to 8 according to the following PV (process value) zones.
Parameter name
PID Set Automatic Selection Data
PID 1 Automatic Selection Range Upper Limit 200
PID 2 Automatic Selection Range Upper Limit 400
PID 3 Automatic Selection Range Upper Limit 500
PID 4 Automatic Selection Range Upper Limit 600
PID 5 Automatic Selection Range Upper Limit 700
PID 6 Automatic Selection Range Upper Limit 800
PID 7 Automatic Selection Range Upper Limit 1000
Input indication range upper limit
• Set the PID Set No. parameter for program 0 to 0 (automatic selection).
• Set the PID Set Automatic Selection Data parameter to PV (process value).
• Set the upper limit of each zone as the automatic selection range upper limit for each PID set.
In the following example (PID Set Automatic Selection Data = PV), PID set 2 is automatically selected
when the PV is 240°C.
