PID Set Automatic Selection Data
PID Set Automatic Selection Hysteresis
The control must be set to 2-PID
control.
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 selection
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.

Position-proportional control must be
supported.
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.
