that the arc has to be a 90
° arc, i.e. the numbers of output pulses in X and Y axes can be
different.
13. There are no settings of start frequency and ramp-up/down time.
14. There is no limitation on the number of times for using the instruction. However, assume CH0 or
CH1 output is in use, the X/Y axis synchronized output will not be performed
Program Example 1:
1. Draw an ellipse as the figure below.

X
( ) 16 00 ,22 00
( ) 32 00 ,0
( ) 0,0
(1 6 00 ,-2 20 0)
2. Steps:
a) Set the four coordinates (0,0), (1600, 2200), (3200, 0), (1600, -2200) (as the figure above).
Calculate the relative coordinates of the four points and obtain (1600, 2200), (1600, -2200),
(-1600, -2200), and (-1600, 2200). Place them in the 32-bit registers (D200, D202), (D204,
D206), (D208, D210), (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 the ellipse.
