    Lot of experiments with genuine Huanyang VFDs

    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 this

    For 120v this input wiring is correct but for 240v it is not to Code, the VFD Drive Output Wiring is also not to Code in either case

    Wires must be the correct color White Neutral wire can never be used for 240v single phase unless it is covered at each end with Black or Red

    If your spindle has 4 pins, ignore pin 4 as it is spindle ground and wont be used.
    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 1-2-3-4G

    The 3 pin connectors also must be changed for a 4 pin connector so a correct Ground can be connected through the plug and to the Spindle Motor, the best thing is to never buy a Spindle that has a 3 Pin Plug these are for China only

    This is a major Safety Problem not using a Ground Wire for these 3 Phase Spindle motors and a Code Violation

    Re: Lot of experiments with genuine Huanyang VFDs

    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 irresponsible

    What you do nobody cares, it's what you show that needs to be correct so others can follow by example and wire to code and not have any safety concerns

    Ok, lets agree to disagree.

    but seeing as you spend half your time defending Chinese spindles, why bother defending western codes?

    which you normally can't be bothered to specify the code anyways?

    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 more

    Has nothing to do with western codes, the same codes apply the world over Green /Yellow known as PE or Ground / Earth no matter what country you live in, it can't be used as a Power / Live Supply Cable just the same as a Neutral can't, you don't have to know any codes, this is a very basic wiring practice that anyone doing a video about wiring should know this

    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

    Re: Lot of experiments with genuine Huanyang VFDs

    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 RPM

    GC in NA and deal with inspections on a monthly bases. I see electricians now use 2 wire cable(+ground) regularly for 220 lines, as long as white is taped at panel and connection passes with no problems.
    Using the forth pin for ground is connected to spindle case and see absolutely no difference using the spindle mount.

    Correct Dan, as long as it marked. In fact I have a Mini Split HP 230 volt running on wiring marked so.
