So I have a 2010 Haas TL-1 lathe that I've decided to convert to Centroid control. Does anyone know if the Yaskawa AC servos and Haas branded "smart amplifiers" are usable for anything?
The servos appear to be a Sigma 1 and they don't appear to have a readily available driver outside of the Haas system (at least not that I've found).
I'm guessing the answer is try to sell them and replace them with servos and drivers that are easier to work with (and I'm open to suggestions there).
Can I do anything with Haas servos and "smart amplifiers"

hello.
are you thinking using Oak? or Acorn?

That motor has a quadrature encoder with A, B (etc.) outputs. It is incompatible with Sigma 5 or Sigma 7, which work with serial encoders.
I think the drives only work with a proprietary protocol, but don't have any solid evidence to back that up.

Re: Can I do anything with Haas servos and "smart amplifiers"
I believe you're correct. I did speak to a sales rep when I was considering Oak and he indicated that I likely couldn't use those servos with sigma drivers.
I'm leaning towards Acorn. Initially I was thinking Oak since this is technically and industrial machine and I thought it might scale better, but then seeing that the axis servos are only 450w and the spindle motor is 3.7kw (just a Baldor 3ph motor) it really makes more sense for my uses (very hobby level) to go with Acorn.

Re: Can I do anything with Haas servos and "smart amplifiers"
Another question, would it make sense to adapt a serial encoder? It appears that these encoders are attached to the back of the servo with a separate(ish) housing, and I'm making some assumptions that it operates by spinning some sort of optical or hall effect sensor on the other end of the servo spindle?
This might be unreasonable to do and obtain any level of precision though, I don't know.

Okay then go for the acorn,
Sell the existing Haas axis motors and drives on eBay.
Purchase new axis motors and drives that are well documented in the acorn tech sphere and you will be much further ahead of the game. You will get to making parts much quicker rather than spending a lot of time working on a CNC machine.

Re: Can I do anything with Haas servos and "smart amplifiers"
Yeah, that seems like the wisdom of ages right there. My "cheap" side kicks in sometimes and I want to spend 4 hours to make something I could buy for $2.cnckeith wrote: ↑Wed Apr 19, 2023 1:53 pm Okay then go for the acorn,

Any recommendations in the 400-500 watt range to replace those 450w servos?

Re: Can I do anything with Haas servos and "smart amplifiers"
If the manuals are written in Chinglish, stay far away. You won't go wrong with name brands. Delta, Yaskawa, ABB, Glentek, Parker, etc.
Cheers,

Confidence is the feeling you have before you fully understand the situation.
I have CDO. It's like OCD, but the letters are where they should be.

Re: Can I do anything with Haas servos and "smart amplifiers"
I'd say if you are doing acorn just go with clearpath servos. simple, easy and reliable.

Re: Can I do anything with Haas servos and "smart amplifiers"
Im using these 1.5kw on my mazak lathe i converted. Manuals in english and work very well. Cant be them for the price. Prolly gonna order same ones for my 4020 mill conversion too.
