CNCShop VFD Drive VFD Inverter VFD Drive 1.5KW 2HP for Spindle Motor Speed Control (1.5kw VFD) https://www.amazon.com/dp/B012AU2QJU/ref=cm_sw_r_oth_api_i_p2AgBb0T60AC1
I’m not at the shop right now Paul, but here’s the link according to my purchase. The photo on the link looks different from the huongyang brand they sent me then.
The link is the same unit series I have.
I have the manual for it, which covers the wiring and installation.
It can use single or three phase, which is probably where the confusion comes from.

@George_Allen but I wonder why you didn’t buy their 110V unit? You could have saved a lot of hassle
@Mike_Thornbury hindsight is 20/20. At the time this one had the best price for that power. Since then, the prices have continued to decline and availability and variety has increased. Now, I think I would have bought some inexpensive servos and possibly some other drivers (except I do like the gecko) but it was more on the expensive side too. I also will soon likely need a replacement VFD. I bought it long before I began building this machine. I actually had the current drivers that are running the table axis too. But yes, buying a 110v spindle would have been easier.
@George_Allen I love hindsight… except if I do too much of it I trip over what’s in front of me 
Those manuals should get you going. I am using my Kress 1050, so have not used my vfd spindle, but I did wire it up and test it and the docs were straightforward. Ignore the three-phase RST.
@Mike_Thornbury okay great! Thanks!
Only for spindles up to 400Hz. So the 1000Hz spindles for righter RPM don’t work. I have one of these Hitachi devices on my 2.2Kw spindle. They can be configured for RS485 based Modbus control with Mach3. MUCH better then any 0-10V PWM.
@Mike_Thornbury I purchased an Allen-Bradley RCD off eBay. They need to be installed on the outlet right? I asked the Makerspace person about it. He’s going to look at it.
@Mike_Thornbury Does the RCD require a DIN rail?
We use the in-line ones on the cable. The house has one permanently wired at the switch box, too.
Are all switch boxes grounded with DIN rails or another way? Looks like this one may be equipped to connect to one.
@George_Allen DIN rails are never for grounding. Only for mounting. VFDs should have a Protective Earth connector as one of the 3 power input connections. Make sure not to create any ground loops with these.
@Marcus_Wolschon ok. Thanks
You need a sparky to wire in the rcd in the board, if there’s not one already. Not sure on your country’s regs but here every outlet has to have one.
@Paul_Shaw which country requires an RCD for every outlet? That would get a might expensive and complicated to wire up.
Both that I’ve lived in, Australia and New Zealand. Not every one separated but all are protected. They are cheep enough now days no excuse not to. Could save you or your family.
Thats strange - having lived for decades in both countries and been in the electronic/electrical industry in both, the only rules I’ve seen are for new builds, not for existing wiring, and that the new house needs an RCD, just one, at the main fuse box. So when you said ‘every outlet needs to have one’, you were talking metaphysically or what?
