What type of vfd you have? In mine, after running autotuning I get 0.1 in both Motor leakage and Motor mutual inductance. I can manually change Motor mutual inductance but it allows me to change Motor leakage inductance only between 0.0 and 0.1 although the manual says it can be changed between 0.1 and 6553.5
What inductance do you get after autotuning?

I'm using an ABB drive, it does not have those parameters. As I understand it, because of the way these spindles are built they are compact and have low inductance, this can confuse the autotune. One idea offered to me was to connect an output choke to increase the inductance.
