*1 These settings are not displayed if the PID Set Automatic Selection Data parameter is set to DV or the PID
Set No. parameter is not set to 0 (automatic selection).
*2 These settings are not displayed for heating/cooling control or floating position-proportional control.
*3 You cannot set the PID 8 Automatic Selection Range Upper Limit parameter. It will be the upper limit of the
input indication range.
• Autotuning is not performed for PID sets that have the default settings.
• If all PID sets have the default settings, 100% AT or 40% AT is performed.
All of the following conditions must be met to perform autotuning for all PID sets.
• The must be no input errors.
• The PID ON/OFF parameter must be set to PID or a position-proportional model must be used.
• The Auto/Manual parameter must be set to automatic.
• The PID Set Automatic Selection Data must be set to PV or SP. (Do not set it to DV.)
• The PID Set No. parameter for the program to autotune must be set to 0 (automatic selection) and at
least one of the PID 1 to 7 Automatic Selection Range Upper Limits must be changed from the
default setting.
