DVP-ES2/EX2/SS2/SA2/SX2 Operation Manual - Programming

3-432

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.

(0,0)

(26000,26000)

(34000,18000)

(8000,-8000)

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.
