Need Help!- 3/N/PE ~230/400??? everyone gives a different answer

[idtkid]

My Emco PCMill 125's power requirements as stated in my manual are:
3/N/PE ~230/400 or 3/PE ~230

I was under the assumption that it needed ~230v 3phase (~230v when measured line to line between phases) plus a ground and a neutral.

My phase converter manufacturer says I am correct, Emco says I need to be reading ~460v line to line, ~230v line to ground (230v per phase).

Is this just a goofy way of stating its power requirements? Machine's axis drives give an overvoltage error when hooked up to my ~230v 3 phase converter (~120v line to ground) to make matters even more confusing (Emco says its probably a software goof and its just trying to say voltage is off, in this case, undervoltaged by ~230v).

If anyone can enlighten me on this that would be appreciated before I shell out more money on a whole new phase converter/transformer set up. Thanks guys

Hi idtkid

If your manual say you can run it on 230v 3ph then that will be fine but you will have to change the jumpers to do this most of these machines have that option but they can run on the 400v as well
