    //Config
var howWide = 45;

//Reset pan first
sf.ui.proTools.trackOutputWindowResetPan();

var win = sf.ui.proTools.mainTrackOutputWindow;

//Get the two front pan knobs
var pans = win.getElements('AXChildren').filter(function(e){ return e.title.value === "Front Pan Knob" });

//Step through decrementing (turning left) Front Left pan, and incrementing (turning right) Front Right pan
//thus widening the pan (because we start at center)
var steps = Math.floor(howWide/5);
for(var i=0; i<steps; i++)
{
    pans[0].elementClick({actionName: 'AXDecrement'});
    pans[1].elementClick({actionName: 'AXIncrement'});
}

      Here's a version that sets the pan and writes it to the selected clip:

      //Config
var howWide = 60;

//Enable preview
sf.ui.proTools.automationPreview({ targetValue: 'Enable' });

//Reset pan first
sf.ui.proTools.selectedTrack.trackOutputToggleShow();
sf.ui.proTools.trackOutputWindowResetPan();

var win = sf.ui.proTools.mainTrackOutputWindow;

//Get the two front pan knobs
var pans = win.getElements('AXChildren').filter(function(e){ return e.title.value === "Front Pan Knob" });

//Step through decrementing (turning left) Front Left pan, and incrementing (turning right) Front Right pan
//thus widening the pan (because we start at center)
var steps = Math.floor(howWide/5);
for(var i=0; i<steps; i++)
{
    pans[0].elementClick({actionName: 'AXDecrement'});
    pans[1].elementClick({actionName: 'AXIncrement'});
}

sf.ui.proTools.automationWriteAutoToSelectionAndCloseWindows();

            @Fokke I think I forgot to mention this action requires that you have 'Pan' enabled in the automation window.
            We could add that to the script if that's not something you are usually using.

                    Sorry, for some reason it works now.
                    But it does leave PREVIEW on in the Automation Window. See if i can turn that off.

                        ah wait, it works on stereo to 5.1 but not on stereo to stereo tracks.

                            To continue the sequel, i was wrong again! It DOES work on stereo to stereo tracks, but we get the error when the automation mode is set to READ! It should be on Touch Write or Latch.

                      This is great!. Is there a way to detect if the output window is open and if it is move on with the script? Right now it closes the window and gives you an error..
                      Thanks in advance

                          This should help. This is what I use as it considers both track as well as object outputs.

                              let outputWindowState = sf.ui.proTools.selectedTrack.outputWindowButton.value.invalidate().value;
    if (!["open", "output bypassed active open"].includes(outputWindowState)) {
        sf.ui.proTools.selectedTrack.trackOutputToggleShow();
    }

                              It works like a charm, but it somehow breaks the panning setting..

                                  And it somehow also closes all open insert windows?

                                      Strange. Works perfectly on my system. What panning setting is it breaking?

                                  Hi there,

                                  How would you modify it to Set Center% Knob to 0? (not putting it on preview, as I just want a start point with tracks on "read" without going to the center channel on the Center % pan setting...?

                                  Thanks a lot! Happy new year!
