spindle control of PM-728vt using linuxcnc

Yes, that's correct.

Thanks
jim

OK, that's the expected behavior for active low FWD and REV

(because LinuxCNC is not in control of direction of your hardware, your hardwiring is)

My OUT7/OUT8 or Relay suggestions in a previous post should work

Thank you for the information.
I already have pins out-07 and out-08 defined and pulled to the PM-728vt but NOT connected.

If i do a MDI m3 command the halcmd looks like this:
    26  bit   IN          FALSE  hm2_7i76e.0.7i76.0.0.output-07 <== spindle-ccw
    26  bit   IN           TRUE  hm2_7i76e.0.7i76.0.0.output-08 <== spindle-cw
