Problem with "Position outside reach".

Options
Hi,

I built simple welding station: manipulator robot, robot coordinated with positioner and few smart component elemets. But I'm having a problem with position of welding robot. Here You can download my project (password: atuLasej link: https://megawrzuta.pl/download/53c21a398bcce8f0617a6ac9c2ab5d12.html).
I tried to move welding robot or positioner up,down and rotate, add some targets between, use ConfJ /Off. There are another ways to avoid that error?
