Hello,
I don't know a whole lot about vfd's and have read more than a few places that buying a home sourced vfd of better quality is the way to go! I'm about to pick up a:

Lenze ESV222N02YXB571 Variable Frequency Drive - 3 HP Max., 200/240 V, Single or Three Phase Input, 9.6 A Max., NEMA 1 Enclosure, with 2RJ-45 FOR MODBUS

The 2.2kw chinese spindles are 220, 400hz so I figured this one hits all the right notes. I have heard from a few places that some vfd's are only suitable for XXXX application and would like someones opinion on if a cnc spindle will work well with this particular drive.

I attached a few spec sheets if anyone is interested in that.

I have also looked at the wj200 from hitachi, and seems they run about 340$
The lenze I found, I can get it for alittle less than that.

Thanks in advance!
