    What else will I need with it for it to work?
    Water pump, hose in, hose out if it's normal chiller (I have an expub chiller which is for another project which draws 4.2kw) but if it's chunky it might be drawing a lot of power at once won't cost you more to run as it will be on less proportionally but there might be wiring considerations.

    I don't think you'll need anything other than a bit of wiring. I got it, then circumstances changed and it got put in storage - I have literally never investigated it other than to note it was a relatively simple unit - coils, fan, pump etc.

    It's a bit buried where it is but accessible to pull out for you on Sunday.

    Give me a call on 07740-308623 to sort out

    I got it a couple of years ago to use with a big (and I mean big !) TIG welder but never used either of them ,and now I'm having a clear out - the TIG is going as well !
    Hi, sent you a text earlier, did you receive it?

    Ok, I missed a digit in the number. That's why you didnt get it.

    Two questions.

    1. Inverters / VFDs.

    I was sent two in error for the 4KW Chinese spindle. One is a 220V input, the other 380V. My logic says that I can use either with a 220V input (single phase) and that the 380V could later be used if I had a 3 phase 380V supply (different motor).

    The supplier indicates that the 380V one (with a 220V input) will damage the 220V spindle.

    Thoughts?

    2. I am looking to use NPN proximity switches for home locations. Easy.

    The CS Labs IPA unit document shows an example where normal switches are used where home and -- (limit) is the same switch and then ++ (limit) is a different switch.

    Is this commonly done? I was under the impression that there are only very limited inputs that Mach 3 will accept as limits (from 9 to 13 from memory).

    Thanks

    1 will depend on if the 380V inverter can be set to work with 220V. It'll need the DC bus voltage limits changed to stop it faulting due to too low a voltage.
    The output will be configurable for the motor. IIRC you need to set the point at which the voltage gets limited, rather than the current, otherwise you will risk cooking the motor at higher RPM.

    2. Have not got a clue, as it's that long since I've configured anything in Mach.

    Thanks, probably not worth the effort / concern then. Ill just return the 380V one.

    Ill play around with the proxy switches this week / weekend. I wasnt aware home / limit could be the same switch. I cant afford a run away going past my limits - the damage with these motors / big components is difficult / expensive to fix.
