    You will probably have to change a parameter in the VFD because often the relay is set to activate when a fault happens but can be set to turn on when start command is given.
    Thanks, I might look at that. My main point was to show that you can get away without lots of outputs on your controller since that is the subject of this thread.

    Ok and in the spirit of "One-Up-man-ship", I can top that and say my machine doesn't use any Outputs as it's got a "Carbon-based pointing device operating system" ie: my finger which starts the spindle...
