Setting data
• This setting is used for automatic selection of the PID set.
• The PID set number to be used is automatically selected based on
the value set in "PID set automatic selection data". The switching
range is specified in the "PID set automatic select range" (PID
setting level).
• "PID set automatic selection hysteresis" is used to prevent
chattering when the PID is changed.

∗ Automatic selection range upper limit" (PID setting
level) (P.8-32)
• This setting is used on a position proportional type to have PV = SP
when the PV is within the PV dead band.
• This function prevents unnecessary output when the PV is near the
SP.
