Pete, sorry, this appears to have been a less than ideal introduction to CNC.

A word of caution, particularly buying a spindle separately to a VFD, you will likely need to configure the VFD for the spindle - that's the next hurdle. I could suggest contacting the spindle supplier to ask if they have a suitable ready-configured VFD that is affordable.

Just a thought.

Hi Doddy
Just seen this ,,,bugger .never mind onwards and upwards.
Here is a few photos of the VFD that i purchased today , I bought this one as i didn't want to go and spend a load of money on a real good one yet as i would like to see if this set up works first and if it is viable .
The wire for the spindle was marked from 1 to 4 to start with so i soldered Wire 1 to pin 1 . Wire 2 to pin 2 and so on ( this was on the socket for the spindle.
And using my tester on the connectivity setting i tested each wire and connected them as follows

I connected the No 1 wire to the V
No 2 wire to the W
No 3 wire to the U

Then i pressed run and turned up the speed and at H 16 an error message came up.
any ideas please

Did you set the VFD parameters to match your spindle ie: Voltage, current, freq, etc. If not this could be your problem as the defaults may not match your spindle.
I don't know this VFD and don't have a manual to see the fault codes but the usual suspects for fault codes on startup or slowdown is too fast Acceleration or deacceleration settings.

If you have them set to accelerate too quickly and you call for a high RPM then the VFD try's to get to speed in the set time by dumping high amounts of current into the spindle and this trips a Fault because it pushes higher than the set parameter. Likewise if you haven't setup the VFD parameters and it's on the default which is often set low the same will happen.

Also the poles the poles 2 or 4, Just a thought. Need the manual

Thanks all
Will photo the manuals

Sorry guys got an early 4.00 am start tomorrow need to get a bit of kip

...So the H016 is some indication of speed (Hz?) - what was the error code?

Also... did the spindle start to spin?, or at least grumble a bit?

...and have you seen this post...

...I've not reviewed it in detail - but superficially it looks good.

Didnt do anything or any noise


Interesting ...........got to go back to work so will let the Mrs have a go , told her it will be ok to stick her fingers in the VFD wiring

I do think that VFD parameter setting is the way forward on this. But, just thinking about the wording above - I understand about 1 to V 2 to W and 3 to U - that's fine. Provided that the wires 1-3 on the motor are connected to the windings. 95% convinced that they will be, but work checking. You said "using my tester on the connectivity setting I tested each wire" - I don't quite understand your meaning. If I was testing which 3 of the 4 wires then I'd use a multimeter on the resistance range, and measure between wires 1-2, 2-3 and 3-1. These should all read about the same - somewhere around 1-3 ohms (I'm throwing a bit in for meter leads etc). And 1-4, 2-4, 3-4 should be open-circuit (possibly a high value if 4 is connected to the spindle metal enclosure - especially if held in your hand whilst measuring. If I squint hard enough at your words I could guess that's what you mean, but it's worth checking. VFDs don't particularly like having no load connected, and hate having a load disconnected when running, so worth to double check your understanding of your wiring before you power-up again.

Let us know how you get on with this, and the parameter setting. Oh, and note down the original settings for each parameter changed, if already set to non-factory setting in the manual.
