Deckel-Maho DMU 50T

 

 

Hello, Str8jacket,

would you mind sharing which US based company you ordered the encoder adapters from? I am looking to retrofit a Deckel Maho DMU 50M (very similar to your 50T, but with LS486 encoders instead of LS486C). I too am currently wondering how to convert the signal to TTL properly. It's looking like the only tried and tested solution is the Heidenhain IBV 600, but they are obscenely expensive, I may as well change the entire encoders.

I also found those Aikron adapters and am wondering if they'll do the job. Are they the ones you ended up going with?

Thanks.

I used this IC:

www.ichaus.de/product/ic-nv/

I had a Heidenhain rotary encoder with the same 1VSS signal. The IC converted it to TTL. Worked (and still does) flawlessly.

Included is a Layout for 2 and 4 Layers. I used the 2 layer board. But with prices so cheap, i would order the 4 layer for better signal integrity.

Hi Stenly, I bought these Signal converter . They cost a lot more than I wanted to spend but at the time I thought I was going to get it going quicker. Approx $130USD each. The Aikron ones might be worth the gamble. Or if you are more tech savvy than I am currently then the ones jochen has linked would be a option. Here is their reply to my email for the ones I bought.

"Your calculations are very helpful.  The HEIDENHAIN LS 486C has a 20µm resolution glass which, as you correctly calculated, will produce a 10Khz signal at 12m/min.  I have attached a data sheet showing the federate limits of each interpolation version for your reference.  You can choose any interpolation option from 0.5x to 5x.  The 5x interpolation model (SA 1872) will provide you with a 1µm TTL output signal. "

In all likelihood they just have the chip jochen has linked image missing /media/kunena/emoticons/ermm.png

Not sure what has happened to that link? but it still works?
