This command moves CNC motors with the specified velocity, acceleration time, deceleration time, and
jerk time to operate a tool in an arc motion from the current position to a target position.
For relationship between acceleration time, deceleration time, and jerk time and the speed waveforms,
refer to the programming example of
G64 Continuous-path Mode on page 2-22.
When this command is executed, the arc path is calculated on the XY, YZ, or ZX plane. If you select an
axis other than those composing the plane to specify a position, the path is linear.
If both IJK and R are omitted, an error occurs. Also, if R0 is specified, the linear path is set.
