I purchased 2 Emcoturn 320's, one with the Fanuc O-TC controls and the other with the Siemens control. The Fanuc machine was viewed powered up with an alarm.
The 2 machines were brought home yesterday.
Here is what I have done and found so far.

Both machines came with the factory supplied transformers to step up from 3 phase 230 VAC to the required +/- 5% 380 VAC.

I've Purchased a AD-10 RPC and am currently connecting it up.

I've already Uploaded the Config file and sheet for another user in hopes he can us the file to get his 320 working.
I've also purchased a WiFi DNC to save and upload config and programs to the 320, I'll document how that goes as well.
