This parameter is used to execute auto-tuning (AT).
• When auto-tuning is executed, the MV is increased and decreased
around the SP to obtain the characteristics of the object of control.
The PID constants are calculated from the results and the Propor-
tional Band, Integral Time, and Derivative Time parameters are
automatically set.
• Normally this parameter is off. AT is executed by pressing the U
Key to select the PID set number. AT cannot be executed while
control is stopped.
• Select 0 to specify the PID set currently being used for control.
Select a number from 1 to 8 to specify a PID set number.
• The AT Execute/Cancel parameter automatically returns to off
when finished.
• The SP flashes if the Present Value (PV)/Preset Set Point parameter
is monitored during AT.
• The channel cannot be changed during AT.
