Works well but just a couple of comments. The spindle is HUGE and the inverter is small, despite how it looks in the photo. Measure things it so you really know what you're getting. The other thing is, the inverter was ordered as a 220v unit, but was set from factory as 380v output which caused a lot of heating in the spindle on it's first run and over current shutoff in the inverter. Took me a while to figure out what the problem was. This should NOT have happened, factory seeing should be correct when ordered as a set. If you order one, check all settings before running.
