Many of you have the same setup. Where do you find the connector?

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.!

If your wanting the Barb Fitting that screws into the pump then try these people.

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.

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

1. I believe it is ok to run the vfd without being connected BUT do not connect or disconnect with it powered up.
2. Yes it will be OK CY cable is generally used but you have already purchased it so use it.
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.

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.
