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.

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

...okay...
I'll take a look tomorrow night. Hopefully you're getting no shocks off this - but without configuring the VFD I'm not surprised that you've got errors. Try having a look at the manual (a link would be useful if available online - VFDs are all different). Try not running it until we have the VFD configured,.
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?Quote:

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