5 Advanced Operations
Using Automatic Selection of PID Sets by Zone
You can set the PID Set No. parameters in the Program Setting Level to 0 (automatic selection) to auto-
matically select PID sets by zones.
• The PID set is automatically set according to which of the preset zones contains the PV (process
value), SP (set point), or DV (deviation) (as specified in the PID Set Automatic Selection Data
parameter).
• Set the upper limit of each zone as the automatic selection range upper limit for each PID set. Set the
upper limits so that they increase with the higher PID set numbers. The PID sets will be disabled if the
set values are in the reverse order.
• To prevent chattering when changing between PID sets, you can set hysteresis in the PID Set
Automatic Selection Hysteresis parameter.
The setting for
PID set 8 is always
the upper limit of the
sensor indication
range.
