Hi,
i have the same massage poping up on three robots i am working with atm.
usualy when "fence open" is the problem what made them stop, but other reasons for them to stop would trigger that massage aswell...
one robot is using linetracking and the other two work with rail-tracking.
everytime one of them is "disturbed" while in the tracking programm, they throw these masage upon atempting to continue their work. that makes it impossible to restart them in the auto-process without taking the TP in my hand to move them in t1/t2...
i know some said i could disable it, but funny part is that in Menu -> setup -> resume tol. the function is already on FALSE...
