• This parameter provides the data for automatic selection of the PID set.
• The PID set number to be used is automatically selected according to the
data set in the PID Set Automatic Selection Data parameter. The selec-
tion range is specified in the PID Set Automatic Selection Range Upper
Limit parameter.
• The PID Set Automatic Selection Hysteresis parameter is used to set the
hysteresis to prevent chattering when the PID set is changed.

• For position-proportional models, control is executed with the process
value equal to the set point when the process value is within the PV dead
band.
• This function prevents unnecessary outputs when the process value
approaches the set point.
