Mesa & Modbus

I'll test this right away and update. Thank you.

Update: I've tried both suggestions but the VFD still isn't increasing Hz when asked. Rodw I replaced my line with your two and it does make better sense to me visually.

It's been a while since I created my original modbus config but I believe the reason I needed to enable spindle at speed is because I'm not currently reading spindle RPM. Having spindle at speed enabled allows a program to continue after an RPM when called, else the program pauses indefinitely awaiting the spindle to reach the requested speed. With my new Mesa Hardware I will have the ability to read a quadrature spindle signal and at that time I should no longer need spindle it speed.

I'm not 100% up with Spindles because my machine is a plasma cutter but I think you will always need a spindle at speed because motion will not start without it.

I have a fully functioning config for a Huangyang VFD working with a Mesa 7176e via Modbus - I'll share it tomorrow when I'm back in the evil laboratory.

Right on. Thanks!

if it can help you this worked on my cnc. now I changed everything.
the type of card does not matter to me. calls to these files and an xor are sufficient.

Here is the final product that worked for me. It was all shamelessly stolen from the posts linked below. The first post is a stepwise command line walkthru of basic connection testing, the second is the configuration I copied and updated for the changes to LCNC and HY_VFD driver. You'll need to comb through it and edit the connections to match your configuration, but this should be a decent roadmap. I've stripped each file down to just the parts relevant to VFD control and display.

Note: The files define far more than basic spindle connection -- there's a glade panel that puts a very nice speed display tab in the Axis GUI. You can use it or not, but you'll have to pick it apart yourself. I barely remember what it took to get to this point, so good luck in the hunt.
