4.6.4. Machine Rigidity Setting for Online Autotuning
There are 16 machine rigidity settings for online autotuning, When the machine rigidity setting is selected,
the servo gains (speed loop gain, speed loop integral time constant) are determined automatically. The
factory setting for the machine rigidity setting is 5.
