hey are people getting this? I just got a email saying it got bounced
update on encoder splitting to altivar vfd and mesa card hey guys just a update and a few more questions so I managed to get the encoder mounted on my spindle and working fine. the vfd works in closed loop control now and I get quite nice power control at almost zero rpm its great actually. now I need to get that encoder output into my mesa card the encoder I have can have any voltage from 5/25 and output equals input. the vfd senses low state at under 1.5 and high state at over 7.7v the vfd sends 12v out into encoder currently so my plan is to just put a resistor in series on the 12 v out to encoder to bring the power down to 10v or so. then the mesa ency card will work I think and I can split off the feedback to the mesa card and get the orientation in linuxcnc working and rigid tapping. so big question is what value of resistor do i need to bring the volts down a bit. regards Andrew On Fri, Apr 16, 2021 at 7:41 PM andy pugh <bodge...@gmail.com> wrote: > On Fri, 16 Apr 2021 at 07:25, andrew beck <andrewbeck0...@gmail.com> > wrote: > > > if manual says I can run up to 13v do you think I will be fine? > > I am not PCW, but I would be nervous about 12V with an absolute max of 12. > Maybe you can use one of the tiny buck-converters from eBay to supply > the encoder with 5V (or 8V) from the 12V? > > -- > atp > "A motorcycle is a bicycle with a pandemonium attachment and is > designed for the especial use of mechanical geniuses, daredevils and > lunatics." > — George Fitch, Atlanta Constitution Newspaper, 1912 > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
