I have been doing a lot of experiments on my Huanuang (Genuine) VFD. I now have three of these.
1. 2.2 KW unit 220v input
2. 2.2 KW unit 110v input
3. 1.5Kw unit 110v input
The machines function identically, you just change parameters based on what motor or spindle you are controlling.
Note that with the genuine Huanyang VFD you can control both 110 and 220 volt motors.
So all that said, the write up has been updated.

Nice write up except for some electrical code violations , which I would not advise anyone to wire a VFD Drive and Spindle like thisQuote:

No one in NA or any other country other than China, should be ignoring the 4th Pin this is for Ground and a 4 wire shielded cable must be used in your case from the VFD Drive U V W + G to the Spindle Plug Pin 1-2-3-4GQuote:

This is a major Safety Problem not using a Ground Wire for these 3 Phase Spindle motors and a Code Violation
Sorry, but I am just being practical. I have done it both ways. And with all the experimenting I do, the long (and code way) would take me twice as long and cost me twice as much. If these VFD hookups were going to be permanent, I would probably do it a little different. Most DIYers just are not going to do that. Home shops have even more.
Most folks will do what they need to , with what they got. I'm sure every single house in NA has code violations.
I will however, put a comment in the write-up, that this is how I do it, and that they should lookup their electrical codes for their municipality. I will lay odds that not a single one does.
Most on the Zone that use these spindles and VFD Drives wire them correctly and to code, showing and saying it is ok to do it like this is very irresponsibleQuote:

Ok, lets agree to disagree.
but seeing as you spend half your time defending Chinese spindles, why bother defending western codes?Quote:

and most everyone on this forum knows 4 pin spindles don't have the 4th pin connected to anything anyways, might as well buy shielded cables and connect it to nothing.
Show me once that I have defended a Chinese Spindle they are what they are Quality is what you get for a cheap Spindle like this, the only good thing is how they have transformed the Hobby router business nothing moreQuote:

It's very easy to connect the 4th pin on these Chinese Spindles if it is not connected, which most know about and do correct so they have a good Ground connection
It's videos like this that confuse new users into thinking it's Ok to do wiring like this when it is not, and is a Safety Problem for the user :)
Code and unsafe operation. White should never be used at a Hot wire unless its marked Black or Red or some other color other than white / grey / green. Motor must be grounded in some way, assuming since the motor is mounted in a metal holder and that holder is grounded via the frame is incorrect. The fault current would need to pass either through the Z mount bearings or shielding on the correct VFD shielded cable.
Mac and I disagree on the method of grounding as I use the ground wire in the VFD cable grounded to the spindle mount, he prefers to see it on the 4 th pin, either way the motor is ground per NEC.
Going without a ground if not only foolish but dangerous. Yes I am a retired master electrician with a license.
I thought all of the Chinese spindles were 2 poles. In your write up you say 4 poles for the 220v version.
They do make some 4Pole but most are lower RPM if they are 4Pole and 24,000RPM then you need a 800Hz VFD Drive and the Huanyang VFD he is talking about only go up to 400Hz so can only run a 2Pole Spindle Motor at 24,000 RPMQuote:

Correct Dan, as long as it marked. In fact I have a Mini Split HP 230 volt running on wiring marked so.
Yes that is how it is done and what we have been posting, using the correct cable for the job is easierQuote:

I've done the 4 pin mod to my 4kw spindle, I tapped a screw on spindle cover same as pics found with a search, you will find mine also. Like I posted I do not see a difference if I used my spindle mount that clamps around half my spindle.
This is certainly a option for the DIY hobbyist that's uncomfortable taking there new spindle apart and not having a ground at all.
You are not making it very clear how or what you are doing, if you are attaching the Ground wire to the mount then that is fine, you have a Ground wire, the only problem that can affect some that do this is noise from the unshielded wireQuote:

Sorry about that, yes what you described above is what I meant and why confused with your first response .Quote:
