9.2.2 One-Parameter Auto-Tuning
Function Description
This tuning function is similar to the tuning-less function, using an Autotune parameters adjustment
module that updates the position loop and speed loop parameters in real time based on the servo operating
state (position, speed, current).
Only the parameter Pn101 (Servo Rigidity) needs to set in One-Parameter Auto-Tuning function, and
Figure 9-5 shows the block diagram in One-Parameter Auto-Tuning.
