So if your Spindle was lasted used on 380v Three phase supply then it will be wired in Star config. If used on 220V single or three phase supply it will wired Delta.
If your Supply is 220V Single phase then you need spindle config to be Delta.

Regards the wires then I cannot tell you from that picture. On the VFD they will be marked so thing like ACM & V1 or Gnd & V1 or Gnd & A1 depending on type of speed controller.
If your not sure what doing then suggest you don't go poking around because some speed controllers can be at Mains potential and very dangerous.
Sorry I'm too far away to help.

If you send better pics of spindle inside the cover I can probably tell you if Star or Delta. Like wise if send better pics of VFD or The board I can tell you which wires to measure from but if your not confident with electrickery then still suggest you seek advise or help from someone who is.

Thanks again Jazz,

Will wait for my colleague to come in later and will take some better pictures for you as I think that is the only workable route since you don't fancy a trip to London. We do have confidence and are quite good at taking anything apart though :)
We have already tried contacting all the companies that we could find in the UK but no luck so far as most don't work with mach3 or simply are not interested as the machine was not built by them. On the other hand the Chinese support proves to be quite difficult due to the 8 hours time difference and the even bigger language barrier. Basically we have been trying to sort this problem out with them for over a month now.

Thanks again and will try to post those pictures later.
