Threading with A B phase only?

Hi
Thank you very much for the very fast response. The situation is that I have already made - for Mach3 with ESS Smoothstepper - the wiring with 24VDC. - Is there any other way to install the index signal on the 7I76E? For example, on a port on TB5 or TB6? A and B signal I could refer directly from the servo inverter. The index signal however not, since I have the engine 1: 2. So I would then get 2 index signals per revolution. And that probably can not be entered into a LinuxCNC config file?
Regards
Daniel

No, the index is part of the encoder component in the firmware, and the pin assignments are hardwired there.

But, as I read it, PCW was saying that it will work anyway, you need a pullup to 5V, but one already exists.

Thanks a lot! I think that I will run the Omron on 5V. So there will be no problem!

Hi Andy I was just wondering 8 years later how your converted Emcomat 20E is running? Are there any recommendations you can offer in hindsight that might improve the retrofit? Kind regards, Adam

Adam, Still running fine however I really only use it a few times a year. I can't believe its been 8 years. I don't really have any suggestions. Did you get yours converted over?

No, I fell at the first fence!! Failure to understand LinuxCNC, frustration in setting it up on my pc, then thinking even if I mastered the pc I'm not really sure I want to be tapping at a pc key board in the oily workshop. Time flies by and 8 years later this week I came across the Mesa 7176E, Nema 34 motors and DQ860MA drivers sitting in a drawer in my office . Actually I did mount one motor to the leadscrew but never connected it to anything. I've been using the lathe entirely manually after fitting a carriage handwheel twice the original size. I think I should buy the rocketronics.de ELS controller where I do not have to stretch the brain. Or another similar idiot proof package if there is one. I will be happy just to have carriage control for threading and general turning. Probably try to sell the Mesa 7176E on ebay.
