Hi Bent,

It looks like you are only reading registers, not writing (sending) any commands to the VFD register which controls start and stop and the spindle speed. I include pictures of my Modbus Master screens, yours should look similar regarding start / stop and spindle rpm command. Of course, register numbers don't match, so you can't just copy mine, but as you see, I am writing to a register for on/off and rpm. That process in my case can be done in one commend, or two if I wanted to, but I do it in one.

Hi Ben,
How is it going? Did you manage to use Modbus?
