G540 Wiring question

[wendtmk]

Hi.
I need a bit of help figuring out the Vfd for my spindle.
I will be starting with a 800w spindle, later on upgrading to a 1.2kw.
So as i was advised earlier here, I need to buy a Vfd with capacity of 1.2kw. So far so good.

My studio where the machine will be placed, has single phase AC power. The spindle and vfd need 3phase power. When i read online, some people say you cant convert, and some others say the 1phase needs to be converted to dc, and then converted again to 3phase. Some others say a VFD should do this. But a few vendors selling vfds locally had heard nothing about this.
I have a feeling if i dont know enough about it before i approach these guys again, I'm going to get fleeced, and how.
What is the least painful path for me to take?

Regards,
Seshadri

This should be a separate post in the Spindle/VFD forum since it has nothing to do with Gecko drives.

Here is a recent post of mine that shows one way of hooking up the G540 to the PLC input of a VFD, it shows a Huanyang, but most have the option of sink or source input direct, without the need for the relay.
