I have my mill apart for a CNC retrofit and I figure, why not put on VFD while I'm at it?
It looks deceptively simple, so I might be missing the obvious. :-)
Here's one page I'm using as a guideline:
VFD Control Box
And I'm looking at using the GS2:
My current questions:
- does the GS2 really replace a phase converter?
- should I go direct drive between the motor and the spindle or should I keep my gears and just lock it into the lowest ratio?
