First steel diy CNC router build

[routercnc]

I think you've tried every combination except the correct one! For single phase you needed to wire up:
R = brown (live)
S= (not connected)
T = neutral (blue)
9 = earth (yellow/green)

P/PR not required to get it running - these are if you want to add a brake resistor to quickly stop the spindle. Useful in a production environment where cycle time is money, but for DIY user this is not required.

This is the instruction sheet I was sent with my VFD:


Here is my unit wired up:


If this powers up then you then need to set up all the parameters. Some time ago 'Husky' collated all the useful info on that so have a search.

Last thing before attaching spindle - it is worth just a double check across any pair of leads to your spindle to check there is a few ohms of resistance. If all is well then connect the 3 spindle cables to 'UVW'. The order does not matter. If once it is all working you ask for 'forward' and the spindle goes in reverse, then swap over any PAIR of UVW cables. Obviously switch off before you do this.

Routercnc is correct I have re checked mine and it is indeed R and T for the mains. No link on the braking resistor terminals.

Here is the link post 6 for the setup. http://www.mycncuk.com/threads/5814-...ce-More/page12 ..Clive
