When I researched that spindle-matching inverter combo before I bought it, I came to understand it was designed to run off 360v 3phase (as in European line voltage) and was rated at 2.2kw. However on the 220v available here, it drops down to 1.5 hp. Some day I plan to borrow a car mech's tach to check it's rpm but I'm fairly certain it's 16k rpm max.
Troubleshooting the VFD is more time than I want to spend coming up to speed on it's electronics. I spent a week designing and building the parport interface, before starting the mechanical build of my axis's (now that I can etch my own circuit board, it'd take an hour counting doing the blueprint and g-code conversion). If the VFD completely fails or if I add a tool changer, I'll replace it, otherwise, repairing it is postponed until I'm retired <GRIN>. For the price of a twist of finger and thumb, it works fine, so I'm happy.
