Please check the axis' status in MAX (1D-Interactive). How is the limit
switch status in MAX? You can run it in parallel to the Motion
Assistant. Does the problem go away when you invert the limit switch
polarity in MAX? Which version of NI-Motion are you using?
If you can't resolve the problem please export the motion settings in MAX and attach the XML-file to this thread.
