Explanation
1. This instruction draws a circle based on relative positioning. S
of the center of a circle (relative position).
2. S is the setting value for function selection. See the descriptions below.

3. D and D are the pulse output devices for the X and Y axes respectively. Refer to DPPMR instruction (API 2710)

for the selection of output points and output mode for the axes.
4. S sets the target frequency for the reference. The target reference frequency is used for the prior calculation when
4
the PLC plans the travel path for the arc after the instruction is executed. But if the calculation process which is
estimated cannot achieve the planned arc travel path, the output frequency is automatically decreased to fulfill the
synchronized arc drawing function.
5. When the X axis coordinate of the center point O=0, point O is defined as the point staying in QI of point A if Y axis
target coordinate >= 0. Whereas, if Y axis target coordinate < 0, point B is defined as the point staying in QIII of
point A.
6. Refer to Example 2 from the DPPMR instruction (API 2710) for programming in ST language.

The arc resolution uses a 10° arc as the basic angle for clockwise motion.
The arc resolution uses a 5° arc as the basic angle for clockwise motion.
The arc resolution uses a 10° arc as the basic angle for counterclockwise motion.
The arc resolution uses a 5° arc as the basic angle for counterclockwise motion.
The arc resolution uses a 1° arc as the basic angle for clockwise motion.
