Wiring Diagram check

[eurikain]

Thanks routercnc for you explanations :) your cabinet looks great ! I've actually got the same DIN rail mounted terminal blocks / relays / yellow-green terminal blocks :)

My question was more about how you stop the spindle. On your diagram, I see the line that goes through the relay and connects to FWD and FVD control interface, but what powers it ? Is that wire getting 24V, or is it just a loop on the VFD itself ? Here is how I understand it: when you power up everything, the spindle can move forward because the loop DCM/FWD is closed. If the relay goes off, the circuit opens and the VFD stops the spindle because its DCM/FWD loop is broken. I am wrong again ?

Also, could you take another photo of your linear PSU please :) ? I like the way you did it but the resolution won't let me clearly see how you connected the capacitors together (it looks very neat).
