1) Set the table information, X-axis speed, X/Y axis position (address) and radius in the XY table information.
2) When turning the X-axis START command ON at the table operation start number with the specified
circular interpolation (radius, CW direction) / (radius, CCW direction), the work piece moves to the target
position at the specified speed, following the circle's center coordinate calculated from the start point,
target position and radius.
