Now drive the gripper along the longitudinal axis (axis 5) using the 
'+' and '-' keys until the line determined by the centering pins is 
parallel to the 0-degree line (tangential to the body axis arc).

Confirm this position using 'Enter'.

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

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