Power Question on a Qkuma Cudet 4020

[phatfred8]

Hello,

My good friend is a new owner of a Okuma Cudet machine. It is a '98 model in really nice shape. Any way he has is moved into his shop and leveled up and is in the process of running the conduit for the power(240 volt, 3 phase).

I have installed cnc machines over the years and it was always in a industrial location, IE had 3 phase power. He will be running the machine on a rotary phase coverter which will fine, but he asked me if there would be a way to wire it so he would not have to have the converter on to load programs. I understand what he is wanting but I told him that the control will probably give him a alarm saying a phase is faulted.

Anyone treid this? My gut feeling is to jsut run the machine with the converter on and move forward. I would hate to see something happen to a drive or control.

Thanks,

Brian

You'll have to have the 3 phase hooked up - the control draws it's power through it. IF you push in on the e-stop button, the machine will use little power and still allow you to look around, upload, ect.

Okumawiz,

Thank you for the reply. I had kinda figured that would be the case but it would not hurt to ask.

it would be nice You have electrician to describe the issue. I don't understand, what's the problem. Do You want to power machine from other source or what?
