$JssorSlider$.$EVT_POSITION_CHANGE fires continuously while sliding.
$JssorSlider$.$EVT_PARK fires while slide change.
Please do this job this way,
function jssor_slider3_starter(containerId_1, containerId_2, containerId_3)
{
var options1 = {};
var options2 = {};
var options3 = {};
...
var jssor_slider1 = new $JssorSlider$(containerId_1, options1);
var jssor_slider2 = new $JssorSlider$(containerId_2, options2);
var jssor_slider3 = new $JssorSlider$(containerId_3, options3);
...
function OnSlidePark(slideIndex, fromIndex) {
if (slideIndex == 3)
jssor_slider2.$GoTo(1);
else
jssor_slider2.$GoTo(slideIndex + 1);
}
jssor_slider1.$On($JssorSlider$.$EVT_PARK, OnSlidePark);
...
}
