• Local coordinate system is created by (2) at the position of "X1500, Y500" of work coordinate system 1. (Local coordinate system is not created in work
coordinate system 2)
• Move to "X0, Y0" of local coordinate system of work coordinate system 1 by (9).
• Local coordinate offset is cancelled by (10), and the coordinates match the coordinate system of (1).
