I received mine a few weeks ago from industry-village and it has a silver end cap where the connector goes and its got 4 pins.Quote:

See the first post in this thread for connection details.
Valeria, It sounds like you have very little experience with electronics so I seriously suggest you get someone with more experience to do this for you.Quote:

Yes and potentially do yourself some serious damage. If you're not 100% certain get an electrician to wire this up for you. With mains voltage, it's better to be safe than dead.Quote:

It seems quite cheap for that power. Too cheap?
Some of the pictures of 3kW spindles says 380V. Anyone has experience with 3kW spindles?
Has anyone measured runout of this spindles and checked how many bearings they have(if that makes any difference?)
Best regards

Just wired my spindle and VFD and followed the diagram in post 1 and it kept tripping.......that was because the pin numbers were different.....
Attachment 15689
Had to cut and re-wire the VFD end as the spindle end is soldered.......still it works now so all good. Just have a look on your connector if you've got the 4 pin variant that's all :stupid:
I recommend checking with a multimeter what the resistance it between each of the pins, as who knows if the companies making these spindles are consistent. You should get a couple of ohms between the motor terminals and zero ohms to the spindle body, or high impedance when they don't bother with the earth.
Hi everyone.
FYI, I just ordered a complete spindle kit from Kevin Ho at ROB BEARING AND MECHANICAL PARTS on AliExpress.
They don't sell it as is, but if you contact him they'll make you a better price than the kit for which I gave the link. Instead of 417 Euros from the original seller (288€ kit + 129€ shipping), I paid 360€ (US $400 round !). I haven't received the kit yet, but I have made quite a few orders with this seller and everything arrives on time and in great condition. Always well packed. He's even offered me some couplers I had forgotten in my last order. It's a factory that produces linear motion stuff but they can order anything you want.
I'll post pictures of the kit when I receive it, but I have no doubts it's worth the price.
Only thing missing is a nice bucket of water, that will prevent you from having to buy a radiator and a fan. With 20-25L bucket you're good to go... you'll be long dead before your spindle raises the water temperature by 10°C !
Hi,
I have a question about water pump. What is the size of the coupling for the hose (pvc 6mm one)? Where I can find this?
Thank you
Gabi
Hi !
The pipes I got with my kit were PVC 6mm. However, I do not recommend those. Personally I find PVC too rigid and prefer much more plastic hose used in gas powered remote control airplanes. If there is a store close to your house that sell that kind of planes, just get it there. It's quite cheap. Otherwise you can order it online :)
I have the pipes. my question was about the connection. The brass connector.
On mine (pump) the seller said is 18mm diameter outlet. I cant find anything with that dimension at one end and with 1/4" or 6mm on the other end.http://www.mycncuk.com/attachment.ph...id=16044&stc=1

Though I have to admit it was quite hard to fit the pipe that came with the spindle. The coupler I have has the same size as the one on the spindle.
Many of you have the same setup. Where do you find the connector?
Cheers
Gabi
Not sure what your asking here . ? . . . The pump in the picture doesn't need or use a connector it's got a Barb so you just push the pipe on and clip it.!Quote:

Hi JazzCNC,
The photo is for reference only. My pump came with a bigger plastic connector. I will have a look on that site.
Still maybe know where I can buy the right one. I bought the 3/4" barb and doesn't fit, it is a hair big...
Thx
Gabi
Got some Noob questions. Thanks for any help.
1. Can anyone confirm if its safe to power up the VFD without the spindle connected for setting the parameters at the beginning ?
2. I have already purchased 3 core foil shielded Belden Cable for my spindle.
http://www.ebay.co.uk/itm/111817521022
Is this ok ?
I just read i was supposed to use 4 core CY Cable.
3. Do i have to earth the spindle at the spindle end by removing the top and making a ground point and connect to pin 4?
E.g. Should I have 4 core cable as well as the shielding ?
Cheers
Martin
1. I believe it is ok to run the vfd without being connected BUT do not connect or disconnect with it powered up.Quote:

3. It is ok to earth the shield at the VFD end only, 4 core is not a necessity .
Just to clarify, this is true for the shield but you should ideally also earth the body of the spindle, not relying on earthing through the machine frame as the bearings are not predictable.Quote:
Originally Posted by Clive S
Yes I agree with that also it is a good idea to put some form of cable restraint on the spindle so as to stop the connections breaking in the plug and causing the VFD to fail.Quote:

Yes exactly that. You can solder or crimp .a short piece of wire and then put heat shrink onQuote:

Ok It depends on how course the weave is on the shield. If it is course you can use a pointed object and tease the cores out through it then you have a strand of shield left to solder to.Quote:

In this pic it is the blue wire with green/yellow sleeve to identify it as earth star point. but the same can be done for the spindle.
Thanks for the image :) I see what you mean.
Now, when you open the spindle cap, you just solder a wire from pin 4 to the spindle shield ? I mean, literally to the metallic shield right under the cap ?
Ok it depends if you have 3 or 4 pins on your spindle socket if you have 4 one of them may not be connected to anything. I took the end cap off and soldered a wire to the vacant pin and put a longer screw in the socket and attached the wire to a ring connector which then fitted over the longer screw and fastened it with a nut inside. Then you can use that pin as the earth in the plug. If you only have 3 pins in the socket then you have to attach the earth to the spindle or clamp.Quote:

I think the first post of this thread needs to be updated with the following information:
- If you're controlling the spindle speed from Mach3, you also need to:
- set PD002 to 1. It might be done automatically, but it's worth checking.
- change the jumper on the right side of the VFD control terminal to VI instead of VR- Set PD070 according to your BOB's specifications. It is the input voltage that the VFD receives on its control terminal. My BOB sends 0-10V, so I had to change the setting. Check the manual for more information.

Jazz previously suggested upgrading the coolant fittings on these spindles for some push fit/lock type, I like this idea so here is a link to some on eBay:
High Pressure Metal Push-in Fittings for Air or Central Lubrication Systems Tube
http://m.ebay.co.uk/itm/271182576634
You want the M8x1 fine thread option for the correct fit, dose/maybe the OP wants to add this info to the first post.
EDIT: Better prices and info can be found here:

OK, guys so before I start plugging in wires is this diagram right?
I want to be able to start the spindle and control the RPM from the EDINGCNC Software
Link to the board manual in case needed http://www.edingcnc.com/upload/files/cpu5a_flyer_tech.pdf
Attachment 18338
Don't know if its just me but clicking on your diagram to view it locks my system, could be links blocked on my sysem for security reasons but only image on site I've tried to view that does this.
Not quite sure what it should be, but I don't think that there should be any connection to the "spindle sensor" pin. That's for sensing spindle position on a lathe for threading purposes, nothing to do with router spindle. I think you've wired the VFD so that it is forward-running only (no reverse, which seems reasonable) but there's no spindle start/stop signal from the board to VFD. I don't know how the Eding board and software handle for/rev or start/stop - I'm going through the same wiring design process with CSMIO/Mach3 and VFD which is a better-documented route.
Yeah seems a bit of a headache

Here is how I have it wired:

I don't have the same board as you but it'll give you an idea. Red / black controls the speed, purple / black controls the start/stop :)
What board is that so I can get a little more info pal?Quote:
Originally Posted by eurikain

You're a gent! Thanks for taking the time!Quote:
