Function
Note 1: Circular interpolation is possible only when a- and b-axis are linear axes. The plane in which
circular interpolation is executed is determined by the plane selection G code (G17 to G19)
which is presently valid. For details, see 2.1.3, “Circular interpolation (G02, G03)”.
2: With a manual pulse generator, simultaneous control is possible in either one or three axes.
For the b -axis, either a rotary axis or a linear axis can be selected.
• A rotary axis (A-, B-, or C-axis) is defined as indicated in Table 1.1.1.7.
Table 1.1.1.7: Rotary Axes
Note 1: The unit of output increment (motion increment) and input increment for a rotary axis is
“degrees” instead of “mm” which is used for a linear axis (X-, Y-, Z-axis). With the exception
of the unit, a rotary axis can be treated in the same manner as a linear axis. (Metric system)
(The NC calculates feedrate assuming 0.001 deg. as 0.001mm.)
2: Even if the dimensions are changed to inches by using the inch/mm selection function, the unit
system for a rotary axis remains unchanged (degrees).
• A linear axis (U-, V-, or W-axis) is defined as indicated in Table 1.1.1.8.
