7i77 -> Huanyang

I made those changes. Now I'm getting 24v on FOR at the vfd at all times even if linuxcnc is closed....it goes to 0 when I push the cw button in axis...is this correct??

I'm getting control voltage reading in hal config but nothing at the 7i77 yet.

I would check this with a Ohmmeter across ENA5+ and ENA5- before ANY wiring is done

If ENA5+ to ENA5- in on (non infinite reading on Ohmmeter) when linuxCNC is not running
you have a damaged OPTO

Sorry I forgot the VFD inpuis are active low inputs with a pullup to 24V so yes thats correct (24V means off at the VFD)

ok thanks. so it looks like its working except I'm not getting my signal out of the 7i77 yet

keep trying things but I'm getting more confused. do you need to see the hal file again??

Sure, post your current HAL and INI files
