Then you should get an Education on the subject before you make such a statement, next time study your electrical code requirement's, Australia has electrical codes in place for VFD installation so you should know better
You can Not Ground / Earth a Spindle like this through a Machine, even if the machine it's self is Grounded/ Earthed, there are to many moving parts with these machines to do this and make it compliant with electrical code
You should keep your thoughts on a subject like this to yourself, talking about half a brain, you are totally clueless as to what you are saying
A VFD needs a Ground /Earth wire the Spindle needs a Ground / Earth wire Plus has to have a Shielded cable to be compliant
China in most areas do not use a Ground / Earth, hence the 3 Pin Connector on these spindles these are non compliant anywhere else in the world and should not be brought by any one because they are cheap, you should check out the rate of electrocutions per year in that country, this is what can happen there with the simplest of devices ( Chinese teen dies after charging iPhone electrocutes her ) Electrocutions happen everyday there
Here is one main reason that a Ground / Earth must be fitted to all VFD Driven Motors, not just these Spindles any 3Ph Ac motor that is used with a VFD Drive, Here is a small lesson on the subject especially for Handwanker,
When power is applied to these Spindles or any AC 3 Ph motor, from a VFD Drive the 3Ph motors Rotor gets energized with Voltage, without a Direct Ground / Earth the Spindle or motor body becomes Live, with enough voltage to electrocute the user
Some here on the Zone found this out the hard way, when doing a tool touch off, by destroying there Breakout Board from a Spindle voltage Spike, and others have been lucky to just get shocked, when they touched there spindles with no Ground / Earth wire connected
This is just a simple expiation that I think most can understand, I don't think there is any reason to get into the full technical details of Rotor voltage that most would not understand

Point taken.....Mac at his obnoxious best.........my high speed spindle on the SVM-0 has a 4 pin socket in the top so that is a 3 phase plus earth set-up......it did come from China too.

It does not matter what the Voltage is code requirement is what it is anywhere in the world, except China, and responsible manufactures in China are working hard to be compliant
It does not matter what you are cutting with your spindle, without a Ground / Earth connected, the Rotor voltage will get you, there will be an electric shock, that you won't forget
If your question is just about machining then yes these spindles are used for all kind of machining, there is a problem with them that is hard to solve for machining like what you are doing, if you pull down on the your spindle shaft you will see why, you will have up down movement, but for light metal machining grinding Etc you won't have to much problem, heavy cutting that does not create a thrust up when cutting will be a problem

I will update my router to spindle post. Here is the link to the spindle/vfd bundle. https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I purchased a 4 pin connector because this came with a 3 wire connector with NO GROUND. I needed a 80 MM spindle mount that would mount perfectly to my CNC Router parts 4824 so I ordered that, here is the link 80 mm Spindle Mount - CRP141-01 | CNCRouterParts, This pump has a long cord and has plenty of lift to the spindle. https://www.amazon.com/Homasy-Submer.../dp/B01LHC91I6 I wired the pump to an outlet that starts when I turn on the power supply to the Gecko 540.
Everything is working fine manually but I am frustrated that I can not turn the spindle on through MACH 3. The digital speed display changes through Mach but the spindle will not turn on. I am getting power to the spindle. I've set the VFD according to many of the posts with similar setups, but nothing yet. When I get finished with some money making orders I will get back to figuring this out.

I am using a G540 and there is a 0-5v and 0-10v available and from what I've gathered this is the same as the relay you've referenced. As I mentioned, the RPM read out changes when I direct it to through Mach 3, but doesn't trigger the spindle on. I've set the VFD for an external signal, set up Mach 3 to accept the signal. Look like 3 wires from the VFD to the Gecko.....inquiring minds want to know. I cant imagine the entire process hasn't been detailed somewhere. Once I get this figured out, I will post the process for others

No, you need both the 0-10V and the relay.I am using a G540 and there is a 0-5v and 0-10v available and from what I've gathered this is the same as the relay you've referenced
Something like this:

I need to research the subject more," PWM 0-10v signal to the VFD and a relay to turn on the FWD connection to turn on the VFD" I am just not getting the wiring, process, and other issues
Did you look at the wiring diagram I posted?
