For the 4th and 5thaxis, circular interpolation is allowed only when they are linear axes.The G code designated to select the plane in which circular interpolation is execu-ted also selects the plane where tool radius offset (G41/G42) is executed. Whenthe power is turned ON, the XY plane (G17) is automatically selected.G17 XY plane, or Xα or Xβ planeG18 ZX plane, or Zα or Zβ planeG19 YZ plane, or Yα or Yβ planeIf an optional linear 4th-axis is selected, circular interpolation is possible in the Xα,Zα, or Yα plane which includes the 4th-axis in addition to the XY, YZ, and ZX pla-nes.
