You most likely have the wrong settings in the VFD, and you may have already damaged the spindle.
I've been working on a DIY cnc router for about 9 months now. I am now to the point of final wiring and the test drive! been a long road...I have a 3kw air cooled Huanyang VFD and spindle from Longs.....I have had them for a few months and haven't messed with them until now, now that's it time to get them going. I did all the VFD programing prior to plugging in the spindle. I got the programming info from a thread off CNCzone. The vfd acted just as the thread described. so I then plugged the spindle in and it started to spoil up then it just stopped about 1200 rpms and did nothing until I hit stop and it would spin a little bit on the way back to full stop. I tried it with and without the ground attached..same result either way. I tried all the combo's with the hot wires and it simply changed the direction of spin at one point, as one would expect. When setting up the Vfd I was looking over the spindle to get the max MHz (300) and I noticed on the plate that at the top it said Spindle and over to the right of that it said Fail.....I know what the means here in the states....did they send me a bad spindle?...…...or am I just missing some obvious thing that i'm not doing? Any help with this would be greatly appreciated....

From what I've read these should be within the operating values, but I am not sure if this is a complete list of all the things that need to be changed.
You could have a lot of things wrong, what voltage are you using and how do you have it wired ??
You never want to change the wiring around on these VFD Drives they have to be wired correct
Parameters also have to be set correct to suit your spindle, so what are your spindle spec's ??

If this is all you set you are missing some that need to be set, these Parameters I have posted won't solve the problem if your wiring is incorrect, need to know how you have it wired

Thanks for the response mactec….I have hot wires from the source (220) to R & S and neutral to T, and the ground to the earth ground at the far right...3 hot wires from U, V & W to the spindle going to pin 1,2 & 3......4 is empty and ground to the ground pin.....I'm going to go back through my settings and compare to what you have.....My real fear is that the motor is smoked because after it spins for just a few seconds it sounds like its still trying to spool up but nothing is happening...and on top of that the motor has fail on the plate and appears maybe it didn't pass a inspection of some type but was sold anyway...but i'm hoping its something like a setting.....i'll check..
Mactec you nailed it.....pd06....was wrong on my setup and the minimum speed pd73 was wrong on my setup....put those in and went back through all of the settings again and tried it and it spooled right up.....thank you !!! now i'm on to wiring into the breakout board so I can run it from mach 3....thanks again
No you can not wire it like that Yon need to remove the Neutral 240v NA does not use a Neutral so you should be connected ( R Hot ) and ( T Hot ) and the Ground ( Green wire to the Ground Terminal )
Now for your spindle the 4 Pin has to be connected inside the spindle to the body there is a good example of this on another post here https://www.cnczone.com/forums/finel...c-forum-2.html Post 23

ok, sorry for the delay there, had some household junk to do.....ok I will remove the neutral and check out the #4 pin example and do that to...before I fire it up again....the router plug has been the biggest nightmare there is very little info on wiring it out there....I just copied the wiring on the vfd off a couple of pics from the net....why no neutral?.....just curious, i'm fine with removing it just like to know as much as I can about it....which is why I chose to build instead of buy in the first place..
Ok I looked at all the photo's on that thread, so you are grounding the #4 pin to the body of the router and not back to the ground on the vfd? Again am good with doing this to, again just curious....have done this type of grounding on some other larger tools before when I had no other grounding options
240V does not use a neutral. It's just two hot wires.
The pin4 ground wire on the spindle does connect to the ground terminal on the VFD.

That is why coping things from the net could have damaged your motor or drive, other countries don't have the same power system as NA they only have ( 1 Hot ) for 220v / 240v supply then they have to use a Neutral
Because 240v NA supply is a split phase, ( answer in it's simplest form ) each hot takes turns at being the neutral, if you don't remove it, this connection has been know to damage the VFD Drive, only 120v NA supply uses a Neutral
If you are using the right shielded cable from the VFD to the Spindle then you will have 4 wires 3 Hot wires and ( 1 ) Ground wire this Ground wire connects to the VFD Ground and the 4th Pin in you plug, and then you mod the spindle plug Ground as others have done, this must be connected for the Spindle to VFD Ground connection to be complete
