Explanation
1. This instruction performs 2-axis relative-position clockwise arc interpolation. S
the target coordinate on X axis, target coordinate on Y axis, and the shift of the center of a circle. Refer to the
following operation for drawing the counterclockwise arc for details.
2. D and D are the output devices for the X and Y axes respectively. Refer to the DPPMR instruction (API 2710) for
1 2
the selection of output points and output mode for the axes.
3. 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. If the estimated calculation process
cannot achieve the planned arc travel path, the output frequency is automatically decreased so as to fulfill the
synchronized arc drawing function.
4. S is the setting value for function selection. See the descriptions below.

Description
The arc resolution uses a 10° arc as the
basic angle for motion.
The arc resolution uses a 5° arc as the
basic angle for motion.
The arc resolution uses a 1° arc as the
basic angle for motion. (FW V1.04.60 or
later)
The arc resolution uses a 10° arc as the
basic angle for motion. (FW V1.04.40 or
later)
The arc resolution uses a 5° arc as the
basic angle for motion. (FW V1.04.40 or
later)
The arc resolution uses a 1° arc as the
basic angle for motion. (FW V1.04.60 or
later)
The arc resolution uses a 10° arc as the
basic angle for motion to create a 90
degree arc of an ellipse and to end at a
point where X and Y axes target
corrdinates specified.
