    I really would not lose any sleep over it the solder the braid and drain wire or crimp will work just fine. I have been doing this stuff way to long and never had a issue. You can make those little clamps if you prefer, just make sure you use a good conductor like copper.

    I think simple cable clamps should work
    I just bought for 2 bux some clamps running wire on wall
    metal clamps

    15 pieces for 2-3 dollar

    another kind for 60 cent
    the reason for high cost is because its german..
    they should stop floding the world with their overengineered crap

    I can't return it because it's been over a year since the initial purchase. I planned on installing it this spring.
    I decided on this water cooled spindle because I don't like the noise or the dust getting blown around from an air cooled setup like a router.

    What would now be my best solution to get the most out of my poor selection? Is it the VFD, Spindle, or both the problem?
    Is there a way to reprogram or modify/change the setup to get 240V performance from what I now have and basically stuck with?

    When I asked the seller about the performance difference between the 110V and 220V, they of course told me similar because they said the VFD controls the motor, not the initial input voltage. They also told me that the 220V VFD version is fed on 1 line (like UK) instead of 2 110V lines like our system does. I don't have a background that would help me know any better


    .
    Well from what I can gather from your link the motor is a standard 220 volt 3 phase spindle motor. You will need to look at the nameplate or markings on the motor to confirm. The VFD since I don't have the information may be able to be feed from either 120 or 240 volts, according to the description it can be. You will need to get the documentation to check. Your UK standard 220/240 two wire it will work just fine. Your power is the same as US 220/240 volt. Only over here we can use one leg of it to the grounded conductor or neutral and its 120 volts.

    So find the documentation on the VFD and double check how to connect for 240 volts and your fine. If it can not be switched to 220 volts then you need a new one rated at 220/240 volts. You will need an equipment ground or earth wire to connect to the metal housing of your motor. Let me know if you have anymore questions.

    Your local hardware store will have most of all you need, you can get a strip of copper or steel what ever is the easiest for you to work with, and make your own saddles or rap around cable clamps, these spring clips can be found in hardware stores look for Terry Spring Clips if you want this type

    It would depend what country you are in as to what voltage you would buy, If you live in NA and you have a 120v VFD Drive then there is no way to change that, to a 220/240v VFD Drive if your spindle is 2.2Kw they perform poorly when using 120v, if your spindle says it is 220v and you have a 240v supply, then you could change the VFD drive for a 220/240v 3Kw VFD Drive

    it working for me

    drive is a sunfar 1.5 kw
    If you live in NA you don't use Neutral for your 240V input power connection , if you have connected a Neutral to the T terminal you need to remove it be for you mess up you VFD Drive

    On your VFD Drive R and S is Hot / Live for 240v NA and Ground to the Ground Terminal any other connection would be incorrect

    Here is what I have which now sounds like junk.

    I would not even consider installing. Sorry. Since since you really have 220 volts . I would try to sell on Craigslist and get one that will work. I did not know they made 115 volt 3 phase motors.

    The sellers who sold me this unit seem to know all about 115 volt 3 phase motors

    I have the (2) 120V line = 240V service in my home.
    Will their 1 line 220 VFD work with (2)120V lines like I have?
    Would you simply connect the (2 )120V lines where they would normally connect their (1) 220V and (1) neutral wire to?

    I could not feel good trying to sell this crap to someone after finding out that it's junk.
    Is anyone out there looking for a setup like this knowing that?

    CNC-Pal are you in the UK?? If your in US which I do not know since you did not list your country, I had assumed your question was about UK voltages.

    Since your UK standard voltage is 220 volts across the line and the center pin is for equipment Earth ground i am almost sure you can not use that safety ground to carry what would be the Neutral line voltage in this country. Legally in US following the NEC you can not use the equipment ground as a neutral. If you needed 240 volts just for the motor you would be fine. You need to check. The so the wiring going to the VFD is going to carry 23 amps at 110 volts.

    But They seem to have an problem with the math involved. The motor nameplate says 110 volts at 8.5 amps, that comes out to 935 watts. Thats a long, long ways from 2.2 kW. more like a little over 1 Hp. 746 watts = one electrical Hp.

    I am doing some research on your power circuits and I will let you know what I find. Well here what I have. Your incoming is 220/240 volts ok, but its two wire. One wire is Hot and the other is Neutral. The third wire is earth or equipment ground. Between the Hot and Neutral is 220/240 volts single phase 50 cycle. Thats it. You can use those two incoming wires to feed a 220 volt VFD rated for single phase and get three phase out.

    So the only way for you to get 110/120 volts is to install a step down transformer capable of supplying at least 23 amps out on 110 volts. A big waster for the price of the transformer and the heavy duty wire needed.

    Instead of trusting what I found on the internet I would contact your local electrician or power company. Sorry.

    When I was working and we had equipment come in from Europe it was always fun hooking it up
