I am trying to use either the DRV or UPF terminal as my spindle-at-speed signal to LinuxCNC via a Mesa 7i76. When I check across the DCM and DRV or UPF with my meter is reads a an open circuit. I tried wiring it like this and it does not work. Any idea how to wire these? I have PD050=01 and PD051=05 so both should be on when the spindle is running and at speed.

I'm using a 10k resistor instead of the 2k picture. The 7i76 side works if I short the leads that I'm hooking to DCM and DRV together.

Hola amigo.
Pudiste encontrar el problema?
Estoy en la misma situación

Mine is working. I'll check after work today to see how I ended up wiring it.

I looked at the wiring on my Huanyang Inverter. I have the 24V terminal connected to the FB terminal. Then the DCM & FA terminals are connected to the 7i76. I have the DCM terminal connected to the TB1 Field Power Ground and the FA terminal connected to TB6-10 (This could be any free Field Input terminal.)

This is my HAL setting.
