3. Instruction Set
2. Steps:
a) Set the four coordinates (-27000, -27000), (0, -55000), (27000, -27000) and (0,0) (as the
figure above). Place them in the 32-bit registers (D200, D202), (D204, D206), (D208, D210),
(D212, D214).
b) Design instructions as follows.
c) RUN the PLC. Set ON M0 to start the 2-axis line drawing.
M0
RST
= D0 K1
DPPMA D200
D202 K100000
Y0
= D0 K2
DPPMA D204
D206 K100000
Y0
= D0 K3
DPPMA D208
D210 K100000
Y0
= D0 K4
DPPMA D212
D214 K100000
Y0
MOV D0
M0
INCP
END

3. Operation:
When PLC runs and M0 = ON, PLC will start the first point-to-point motion by 100KHz. D0 will
plus 1 whenever a point-to-point motion is completed and the second point-to-point motion will
start to execute automatically. The operation pattern repeats until the fourth point-to-point
motion is completed.
