Should I add additional electrical grounds?

Post by Setlab »

I'm putting components into my electrical cabinet now and am thinking about electrical ground wiring. It's possible I'm not considering something but the schematic for the acorn board only has a ground connection between the power supply and the board itself. Is this intended to be the ground for all of the components connected to the acorn board? Should I add additional grounds?

As a side note, I do have a second power supply with a ground specifically to power my axis motors and another AC ground for my spindle motor.

Your drives, the power supply for your drives, and your VFD should all be grounded as well.

The wire gauge for the protective (safety) earth should be at least as fat as the incoming mains wires. And the fuse / circuit breakers should be low enough current to protect the wiring. All the components that have mains voltages in them should have a protective earth.
