6 Parameters
d-p
d-i
d-d
These parameters set the PID constants for disturbance for use in adaptive control.
• These parameters set the PID constants that are used during a steady state in adaptive
control.
Function
• The set values of these parameters are automatically calculated when autotuning is
executed while the Adaptive Control parameter is set to "Notification" or "Automatic
update."
• This parameter is not displayed while the Adaptive Control parameter is set to
"Notification" or "Automatic update." You can check the set value through
communications.
• Do not change the set value of this parameter after it is calculated.
