3. Motion explanation:
When PLC RUN 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 same
motion will keep executing 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 (D200,D202), (D204,D206), (D208,D210)
and (D212,D214).
b) Select “draw clockwise arc” and “average resolution” ( S = K0).
c) Select DCIMR instruction for drawing arc and write program codes as follows.
d) PLC RUN. Set M0 as On and start the drawing of the ellipse.
