Hello. I have been searching for a simple answer and my search skills must need work.

I bought this spindle and VFD
https://www.automationtechnologiesin...ooled-spindle/

I set it up and it seems to function correctly. It spools up to 24000 rpms just fine.

The VFD only allows 7amp as the max amp draw. Isn't that only 770 watts? I set mine to 5A because that is what I saw online. The vendor told me to set it to 11A, but the VFD won't allow that value.

I haven't cut anything yet because my CNC has a couple of other issues. I figured I would upgrade to a real spindle while the machine was down.

The spindle itself has no amperage rating stamped on it. I have seen other 110v 1.5Kw spindles online with 5A stamped on them. It does not seem right.

I am a hobbyist so there is probably a gap in my knowledge here.

Any help I can get would be appreciated.
