Linear Interpolation Procedure
Use the following procedure to perform linear interpolation.
1 Registering Axes Groups for Interpolation
•
Select the axes group to perform interpolation.
An axes group is represented by _MC_GRP[*].
• Specify the axis composition with Composition of the Axes Group Variable. You can specify
two to four axes.
• Specify the combination of axes to perform interpolation with Axis Selection of the Axes Group
Variable.
• Use logical axes (axis A0 to A3) for the axes, and not axis numbers.
• Specify axis numbers for the logical axes A0 to A3 in order from the lowest number with Axis
Selection.
• The axis number is specified as follows according to the model or series.
Model or series Axis number
NY-series Controller Axis 0 to Axis 63
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).
• In the Axes Group Basic Settings of the Sysmac Studio, select the axis composition to use for
Composition and assign an axis number to the logical axis. The following example shows a 3-
axis axes group that is called MC_Group000 with the following axes registered in it:
MC_Axis000, MC_Axis001, and MC_Axis002.
Precautions for Correct Use
An Instruction Not Allowed for Encoder Axis Type error (543D hex) will occur and operation will
end if an encoder axis or virtual encoder axis is included in the axes group.
Make sure that you select only Servo Axes or Virtual Servo Axes.
