7i77 -> Huanyang

My VFDs come on with the main power. And stay on if the machine is on.

Estop kills their power feed, but otherwise I trust them to only turn the spindle when enabled.

Ok I'm assuming now that I can run a wire from tb5 ena5+ to the forward pin on the vfd?? Also, I am guessing the driver that is mentioned is not needed for this method??

A single SPDT relay can be used this way:

7I77 ENA5- to GND
7I77 ENA5+ to relay common
relay NC to FOR
relay NO to REV
relay coil to 7I77 output (DIR)

using the fwd only for a cnc router. can I do: 7i77 ena5+ to FOR, 7i77 ground to DCM
7i77 AOUT5 to V1, 7i77 ground to ACM

Almost but you need to connect DCM to ena5- instead of 7I77 GND
(The enaN outputs are isolated)

moving on to the config.....I largely copied the configs attached above but it's not working yet. could someone take a peek please.

There are several bugs in that (old) version of pncconf
net spindle-vel-cmd-abs => hm2_5i25.0.7i77.0.1.analogout5 !!!! wrong
SB
net spindle-vel-cmd-rpm-abs => hm2_5i25.0.7i77.0.1.analogout5

net machine-is-enabled => hm2_5i25.0.7i77.0.1.spinena !!!! OWW
SB
net spindle-on <= motion.spindle-on => hm2_5i25.0.7i77.0.1.spinena
