I am currently building a three axis machine, and I am much more comfortable with the mechanical side of building than I am with the electrical. If anyone knows an online resource that could help with this, it would be appreciated.

I have three phase 230v power at my shop, the components that will go into the enclosure are as follows:

1.5KW Yaskawa Sigma 5 amplifier, 3-phase 230V

400W Yaskawa Sigma 5 amplifier, 3-phase 230V

100W Yaskawa Sigma 5 amplifier, 3-phase 230V

240W 24V DC power supply, 1-phase 110-240V input

Yaskawa MP2300siec motion controller, 24V input

Small I/O panel


The Yaskawa literature recommends all sorts of relays and line filters. I've been told that most of that stuff is not necessary here in the US. I have nice clean power in an industrial park.

The current plan is to put in a main rotary disconnect on the door. I understand that I should install circuit breakers on each axis, appropriately sized for the amperage. I'm guessing I can distribute power with some sort of terminal rail to split the power for each axis. I know I'm probably missing quite a bit here.

Is it possible to keep everything this simple? Any advice or help would be appreciated, I'll monitor this thread closely and answer any questions to fill in details. Thanks.

If you want the industry standard method, I suggest you get a copy of NFPA79, you may find a PDF copy out there, this give all wire sizes and colours according to the code as well as suggested schematics and method of layouts etc.
After the disconnect, I usually place a required row of fusing progressing downward in rating and wire the top of the fusing in a distribution fashion, if you only have 1ph then the 240/120v live conductors will be fused and not the neutral of course.
Also secondary side of transformers can be fused as well as DC output of Power supplies.

Thanks for the tip Al, I'll see if I can dig up a copy. Does anyone know of someone who put up a build log, that might have included good pictures and descriptions of this portion of the build?
