Re: VFD 5 wire motor

Thanks for the reply. What do you think about the possibility it is electrically excited synchronous type? The second illustration in the video shows a 3 phase motor with 3 +2 wires. The 2 smaller wires may be for DC stator current?

VFD 5 wire motor

I am doing a conversion to Acorn and Clearpath NEMA34 servos. Everything is working great on the axis drives but I am hung up trying to figure out the spindle motor. It is a 3 phase AC motor on a Journeyman 425. I have wired many 3 wire 3 phase motors in the shop thru the years but only now encounte...

Re: Acorn + Clearpath success stories?

Hi, I just did a conversion using Clearpath NEMA 34 servos and Acorn on a journeyman 425. It works great! I am still playing with motor profiles to optimize rapids but it does a nice job. My son and I made adaptor plates to fit the servos into the existing drive mounts. I gutted the entire machine a...

Re: Old CF file transfer heartache

I did not mention this and perhaps it is not relevant but I did have to send the optical interface card back to Centroid to resolve the license for the new allin1dc. Would this missing card prevent the original computer from booting past the bootloader screen?

Old CF file transfer heartache (Resolved)

I need to get my tap and nc files off the old DC3 system and into Windows of the new allin1dc system. Following TB200 with no luck. The linux app explore2fs-1.08beta9 won't see the data on the CF card and Windows keeps splashing me with format request. Of course I said no to format! So I decided to ...

losing analog signal GS2 (Resolved)

I am working on a CNC12 / ALLIN1DC upgrade on a router table. I have everything working except for the GS2 VFD. I continually get EF errors on the VFD. One time the spindle started to spin up when I went to manual mode and pressed the green button on the pedant. I have not been able to get the spind...
