5. When the 2-axis synchronous motion instruction is enabled, the start frequency and
acceleration/deceleration time for the Y axis will be the same as the settings for the X axis.
6. The number of output pulses for the 2-axis motion shall not be less than 59; otherwise the line drawn will
not be straight.
7. There is no limit on the number of times this instruction can be used in the program. However, if CH1 or
CH2 is in use, the 1st group will not be able to send pulses. If CH3 or CH4 is in use, the 2nd group will not
be able to send pulses.
8. Flags: M1029, M1030, M1334, M1335. See Points to note below for more details.
Description: (ELCM-PH/PA)
1. If the maximum output frequency setting is less than 100Hz, the output will be operated at
100Hz. If the setting is more than 100KHz, the output will be operated at 100KHz.
2. When the 2-axis synchronous motion instruction is enabled, the start frequency and
acceleration/deceleration time in the Y axis will be same as the settings in the X axis.
3. The number of output pulses for the 2-axis motion shall not be less than 20; otherwise the line
drawn will not be straight.
4. There is no limitation on the number of times using the instruction.
5. Flags: M1029. See Points to note below for more details.
Program Example:
1. Draw a rhombus like the figure below.
(0,0)
(-27000,-27000)
(0,-55000)
(27000,-27000)
X
Y
2. Steps:
a) Set the four coordinates (0,0), (-27000, -27000), (0, -55000), (27000, -27000) per the figure
above. Calculate the relative coordinates of the four points and obtain (-27000, -27000),
(27000, -28000), (27000, 27000), and (-27000, 27000). Place them in the 32-bit registers
(D200, D202), (D204, D206), (D208, D210), (D212, D214).
b) Set M0 On to start the 2-axis motion.
