How to Set up a Huanyang VFD and 2.2KW Air Cooled Spindle

Yep that is why i was posting that grounded ground grounding cannot be used interchangably because they do not mean the same thing. Another issue I see frequently is people not understanding the difference between grounding and bonding. The second image you posted there causes even more confusion, I have always known the earth ground symbol to represent ground but recently i have seen articles and even some schematic software using the commom ground symbol to represent ground calling the earth ground something different entirely.

You will see items sold here such as BOB's etc and/or a schematic posted and they all use the earth ground symbol as a power Common, regardless if it is non-earthed.
The book highly praised by many, The Art Of Electronics commit the offense all the way through.
The earth ground symbol I show was established by the JIC in the '50's.
Also there is a paper published by Siemens on the importance of equi-potential bonding in electrical enclosures etc.
It used to be available on their web site until they changed the site.
It is available by request in PDF.

Thanks so much for this information. How did you wire the 220v input voltage. I have a standard 220vac US circuit to connect with a red (hot line), black (hot line), white (neutral). What connection points should I connect them to?

Thank you

See Step 1 in the first post. Only use the red and the black, one to "R", and one to "T".
You also should have a ground wire, which also needs to be connected.

If you had read this thread correctly you would see that you can NOT use a White Neutral Wire with a 240V NA supply, it can be 2 Black or 1 Red and 1 Black Plus a Green Wire for Ground /Earth

If you have a White wire in your 240v supply you would also have a Ground this could be a bare Copper wire, you can not use the White wire, when you find the Ground wire you can join a Green wire to it, make sure this is bonded together very well

Are you using the 240vac supply for the whole machine or just for the spindle?

The ground wire hooks up to "e" at the vfd, and the 4th pin at the spindle. Like we just talked about, it's grounded at the "E" end. Wheb people talk about grounding at both ends, I think they really mean connecting at both ends.

Don't over complicate and end up making ground loops. 2 live wires to "R+T", Earth wire to "E", and then "UVX, and E" to 1234 on the spindle..

I brought out my multi meter and checked my 2.2kw water cooled spindle pin 4 for continuity against the metal chassis of the spindle and there was no connection, so pin 4 (on my spindle) does nothing. Probably wise to assume your spindle may not be grounded by wiring to pin 4.

There is a YT video from what looks like an HY manufacturer which at 2:08 states "we usually don't connect earth" when referring to the spindle. Likely why pin 4 is disconnected. https://www.youtube.com/watch?v=Tdn_KANxff4

That's because in China they do not have to use an Earth / Ground connection, anywhere else in the world you have too, so the unconnected 4th pin you have to connect it, you do this by taking the top off the spindle motor if it has a metal top, this is quite easy to do, the good quality Chinese Spindles have the Pin 4 connected as per photo's below

Thanks mactec! Mine has a black top with the 4 pin connector. Is the black top more difficult to remove (I.e. sealed)?

Is it aluminum or plastic, if it is plastic you have to attach the Ground / Earth wire a different way and don't need to remove the end cap, some use a sealant on them so it may take a little persuading to get it off, there are 2 Orings that need to be sealed, that's the only part you have to be concerned with when you reassemble it, blow the water out before you disassemble it, just use low air pressure

So to your VFD you should have the input power connected to the R and T terminals, and the Ground wire connected to the E Terminal if not you will have problems

A Spindle Ground wire is needed so you need to connect another Ground wire to the VFD E terminal and connect to the best place you can on your spindle, this is a must have

Your shielded cable should be terminated at both ends as per snip below

I had a 4kw hunayang hooked up for about 10 months, only used occasionally on a 5hp planer, and it popped recently, loud pop and no longer works. Pics of my hook up below.

Ground (green) to ground on VFD and power to R and S.

UVW from motor to VFD.

Solid copper ground wire from mounting plate on planer to ground terminal on VFD.

Is that all correct? From my reading, the power from wall (220v) can go to R & T?

I also would like to know how to wire a switch of some sort as I have one 220v plug in my garage, the dryer outlet, and it gets shared with the dryer, sawstop, jointer, and planer with vfd. I plug in the vfd, flip the breaker, let the VFD boot up, then use the run and stop buttons to turn the planer on.

I read I can wire a switch of some sort to turn the VFD on and off, preventing some power surging to the VFD or another way to turn the planer on and off instead of from the VFD itself. Any help would be great.
