(NEWBIE) How to use an (Fanuc) AC Spindle servo motor for an DIY CNC router

I'm late to this. I would google the manual for that motor and its corresponding drive. If it is a red cap Fanuc spindle motor, it is a permanent magnent motor and will have no tourque with a standard vfd. Hiatachi wj-200 and Sj-300 will run a pm motor. I have the 12kw version on my Fadal with a wj-200 and it can be made to work. It is a bear to tune and you will need the pm motor addendum from hitachi to calculate the induction volatage constant and set the pm parameters correctly. I have heard that Yaskawa and Fuji also have some low priced drives that will run that motor. Pm motors make lots of current on wind down, you will need a seperate braking unit and resistor, the braking transistor in the stock wj-200 is weak and blows when hit with a big current spike. Been down that road...
