Now drive the gripper along its longitudinal axis (axis 5) using the '+' 
and '-' keys until the line determined by the two centering pins is 
parallel to the +90 degree line.

Confirm the position using 'Enter'.

As before, ROB3 again drives to this position 'dynamically' and you
have the possibility for correction.

Final confirmation of this position using 'Ctrl-Enter'.

This concludes the adjustment of axis 5.
