I just want to be able to manually control the start/stop speed etc with the VFD front panel, but automatically stop when the relay goes off.
Ok well same thing really just controling a different function and how you describe the relay etc is correct. BUT why wouldn't you want the software to Control ON/OFF if you have the abilty.? . . It makes life so much easier.!
You can walk away from the machine and Know it will stop the spindle when finished. It will Stop the Spindle between Tool changes and Start again when press Cycle start. Which is great when learning because it's common for people to push Cycle start after tool change then realise they haven't started the spindle.!!
