I don't really know much about it. there is a big heidenhain service manual online I found that mentioned it. apparently there are also extra boards that allow you to interface a 0-10v signal also which then converts to PWM in the inverter. So I bet there are pretty standard. If I do end up buying this then I will check it all out and definitely be asking here for help. you guys are amazing the way everyone is so helpful
there is a heidenhain service agent here in new zealand that is a good company to deal with also and they would probably help me with any info I need. But I have zero interest in fixing the old control. not that it is bad but I have already been down that route before and it is just a pain. linuxcnc is amazing once it is set up as you can do anything with it. and parts are cheap and I understand enough now to be comfortable with it just for everyone's interest here is a very similar machine to what I currently have and what I am looking at buying for the second machine. Only the one I am looking at has dead electronics https://drive.google.com/file/d/16TQ8mJ7jEkG6OZ7TfgxgSFxu4gopIaLr/view?usp=sharing regards Andrew On Thu, Jun 4, 2020 at 9:06 PM andy pugh <bodge...@gmail.com> wrote: > On Thu, 4 Jun 2020 at 09:53, andrew beck <andrewbeck0...@gmail.com> wrote: > > > apparently it takes a PWM > > command from the heidenhain main controller via ribbon cables > > Do you know anything about that signal?
