I am at a loss. I had someone help me with diagnosing wiring, everything seems to be set up correctly but I get no response on an SxxxM4 command. Any help would be great!
I'm using Linuxcnc 2.8.4
Mesa 7i76E card
Huanyang HY series VFD

1.net spindle-vel-cmd-rpm => pid.s.command

should be
net spindle-vel-cmd-rpm-abs => pid.s.command

2. Is the VFD programmed for ENABLE/DIRECTION rather than FWD/REV?
