ok gene just a update I have the mesa card connected to the vfd now.
currently the analog signal is working fine I can it being read by the vfd which is good. I am having trouble with the control signals though. I currently have the 7i76 spindle enable pin switching the forward pin on the vfd the spindle direction pin on 7i76 switches reverse pin on vfd I am a bit stuck with what I need to do to connect up the hal signals.. any help there would be appreciated. and let me know what info you need from me. regards Andrew On Mon, Mar 16, 2020 at 7:02 PM andrew beck <[email protected]> wrote: > I have a schiender vfd made in France so a proper manual lol. > > It's just the Mesa card I'm not sure about lol > > On Mon, Mar 16, 2020, 9:10 PM Gene Heskett <[email protected]> wrote: > >> On Monday 16 March 2020 00:28:43 andrew beck wrote: >> >> > Hey guys.. >> > >> > this has probably been rehashed a few times but did some google >> > searches and couldn't find it so am asking here >> > >> > I just want to connect my mesa 7i76 spindle outputs to my vfd. >> > >> > I will use 0-10 volts control speed reference and a forward pulse and >> > reverse pulse. >> > >> > I am not sure what actual pins I should be using though and am >> > slightly confused. >> > >> > any help would be appreciated >> >> There are pins designated for that on the 7i76D, what seems to confuse >> folks is that the spindle speed is an electronic resistor that acts >> exectly like the arm of the front panel speed pot on the vfd, but the >> vfd must be programmed to use it that way.
