This is my planned layout for the panel of my CNC control.

This is a proposed wiring layout which I would like comments from people please?


Many thanks for taking the time to look.

Perhaps it is too late now, but here are some things I'd do differently...

I would move that VFD out of the cabinet. You will likely experience some problems with the UC300 in the middle and so near the VFD. The other alternative to moving out the VFD is to move out the UC300 into it's own shielded box.

The other modification I'd do is to install the PSUs in an orientation which would allow the fans to cool and would allow easier wiring. As it is now, you can't stick a screw driver inside the cabinet to attach/detach wires, you have to remove each PSU, screw in all the wires and install the PSU in the cabinet again. That is going to create some practical problems and may result in a not so nice wiring in the end.

A question... are you planning to feed the UC300 with an external +5V? I think that's better than using the PC USB power. Make sure your +5V is very clean otherwise you may experience problems with the UC300. The other thing is that if you want to control the VFD spindle speed with 0-10V you can do that from the UC300 directly, but if you will use Mach3, or some other software with Modbus capabilities than a neater solution is to use the RS485. Considerably better than digital outputs and 0-10V, also demands less and easier wiring.
