4 Axes Group Instructions
• Turn ON the Servo for the composition axes of the axes group, and then define home for each
of the composition axes.
• Execute 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.
Y
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 (axis 0 to 255).
Precautions for Correct Use 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 (error 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). Absolute positioning or relative
positioning can be used to specify the position with these methods. You can specify absolute or rel-
ative positioning with MoveMode (Travel Mode).
MoveMode
Absolute positioning
Relative positioning
The difference between absolute positioning and relative positioning using a border point is
described below as an example.
4-46
CCW
CW
CW: Clockwise rotation
CCW: Counterclockwise rotation
X
The border point for a border point specification or the center point and end point for a
center point specification are specified as absolute positions from home in the axis
coordinate system.
The border point for a border point specification or the center point and end point for a
center point specification are specified as relative positions from the start point.
