    Have a look at the configurable P50 to P56 inputs. I think you need to set them to use Ď3 wire controlí.
    If the input used for stop is high (fed from a NC switch which picks up if the cut is finished) then briefly pressing the start button which is connected to the input used for start should start the machine. I think it should stay latched internally and it will run until the end switch is hit and it goes open. When you raise the arm the switch will go back to NC but it should not start again until you hit start.

    Iím away from the machine and PC and have never configured an inverter to run like this (I have different needs for the CNC machine so hopefully someone will confirm if this is somewhere close!)

    OK having a quick search - the last post here gives a better description of the different modes of operation including 3 wire which I think is what you need.
    I think a momentary start button would start it and either a momentary (NC) stop button or NC limit switch would stop it. Just needs the parameters between P50 and P56 (whichever you are going to use) set to the right values out of the multitude of options.

    Many thanks for your advice, just read the link you sent to model-engineer and there are lots of advice/comments on there regarding these cheap vfd's.
