DVP-ES2/EX2/SS2/SA2/SX2 Operation Manual - Programming
3-436
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). 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.

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.
