Additional Information
For the details of the axis numbers, refer to the NY
-series Industrial Panel PC / Industrial Box
PC Motion Control User’s Manual (Cat. No. W559).
2 Enabling the Axes Group
•
Turn ON the Servo for the composition axes of the axes group, and then define home for each
of the composition axes.
• Execute the MC_GroupEnable (Enable Axes Group) instruction to enable the registered axes
group.
Using the Circular Interpolation instruction is now enabled.
CircAxes (Circular Axes)
Circular interpolation uses the X axis and Y axis.
CW
CCW
X
Y
CCW:
Counterclockwise rotation
CW: Clockwise rotation
Specify the axes to use as the X axis and Y axis with CircAxes (Circular Axes).
Use logical axes (axis A0 to A3) for the axes, and not axis numbers.
Precautions for Correct Use
Specify the Count Mode to Linear Mode for the axes that you use for the X axis and Y axis.
If you specify Rotary Mode, an Instruction Execution Error Caused by Count Mode Setting (er-
ror code: 544A hex) will occur at execution.
CircMode (Circular Interpolation Mode)
There are three methods of circular interpolation: border point, center, and radius. You can specify one
of these methods with CircMode (Circular Interpolation Mode).
You can specify Absolute positioning or Relative positioning with MoveMode (Travel Mode) to
specify the position in these methods.
