Program gets stopped by top z-axis limit switch at the beginning of every pro...

Hey there,
my controller worked great for a few months now, very happy. However a new issue came up:

my Programs gets stopped by the top z-axis limit switch at the beginning of every program. The start of every program is handled by the controller and not that specific file being worked on. At the beginning the axis will move to the top z-position of my Maschine and start the spindle. My problem is that this familiar procedure gets interrupted by the limit switch. As a result the program is stopped. This is not a hardware issue, as the limit switch already got replaced,with the same results. Even the if I trigger the limit switch by hand the program is stopped and the limit signal is triggered including the beep.
controllercontroller / NC file) did not change since the occourance of this problem. What do I have to change in the settings of my controller to get this working again?

Thanks for your help!
