Leon I use a cheap Chinese vfd costs about 190usd And buy a encoder for it. About 50usd and I'm controlling two fanuc spindle motors here fine.
They auto tuned the motor in about 4 secs and run awesome. I can get 150 percent torque at zero rpm. If I run a pid loop in linuxcnc almost a servo level control response Have a look at the video there are links on there. I made it a few months ago https://youtu.be/vARlybdtC6Q I'll message you in WhatsApp too.
