Hi,
good old-fashioned Chinglish!

Chinese VFD's are cheap, but thats about all they have going for them.

I use Delta VFDs (a Taiwanese brand made in China) for twenty years, both on my own equipment and for customers. Never had a failure and vastly better documentation
and set-up software.

ya I ended up just getting another VFD, and from that it works great. I can go reverse now with the commands, only issue is on Mach 4 the spindle default minimum speed says 8000rpm, If i use M3 S1000 or such it wont go below 8000 even clicking the override, goes up no problem.
Everything is properly set to min rpm as 0, is there a setting somewhere I'm missing. This is all to setup the rapid change atc.

I did find this while searching through the files in the profile folder, is this what I needed to change and if so where could I access the settings for this part?
here is a picture. DefaultMinSpindleRPM  0 and 8000 or 1000
