each time a segment of the arc is complete, which also initiates the second segment of the arc.
This execution will continue until the fourth segment of the arc is complete.
Program Example 2:
1. Draw a tilted ellipse as the figure below.
Y
X
(0,0)
(26000,26000)
(34000,18000)
(8000,-8000)
2. Steps:
a) Find the max. and min. coordinates on the X and Y axes (0,0), (26000,26000),
(34000,18000), (8000,-8000) per the figure above. Place them in the 32-bit registers
(D200,D202), (D204,D206), (D208,D210) and (D212,D214).
b) Select “draw clockwise arc” and “average resolution” (S = K0).
c) Set M0 to On to start the motion.

3. Motion description:
When M0 = On, the ELC will start drawing the first segment of the arc. D0 will increment each
time a segment of the arc is complete, which also initiates the second segment of the arc. This
execution will continue until the fourth segment of the arc is complete.
