3. Operation:
When PLC runs and M0 = ON, PLC will start the drawing of the first segment of the arc. D0 will
plus 1 whenever a segment of arc is completed and the second segment of the arc will start to
execute automatically. The operation pattern repeats until the fourth segment of arc is
completed.
Program Example 2:
1. Draw a tilted ellipse as the figure below.
Y
X
(0 ,0)
(2 60 00 ,2 60 00 )
(3 40 00 ,1 80 00 )
(8 00 0,- 80 00 )
2. Steps:
a) Find the max. and min. coordinates on X and Y axes (0,0), (26000,26000), (34000,18000),
(8000,-8000) (as the figure above). Calculate the relative coordinates of the four points and
obtain (26000,26000), (8000,-8000), (-26000,-26000), (-8000,8000). Place them
respectively in the 32-bit registers (D200,D202), (D204,D206), (D208,D210) and
(D212,D214).
b) Select “draw clockwise arc” and default “motion time” (S = D100 = K0).
c) RUN the PLC. Set ON M0 to start the drawing of a tilted ellipse.
