(1) The linear interpolation to other linear axis is executed performing 2 axes circular
interpolation from the current position (start point) to circular interpolation axis end
point address (X,Y) or linear axis end point address (Z), and the helical
interpolation is executed so that it may become a spiral course.
An absolute values or incremental values of the circular interpolation axis end
point (X,Y) and linear axis end point (Z) depends in the modal status (G90/G91)
when executing the Motion program.
(2) Only the number of times specified by the number of pitches around on the
specified circle, and it is executed positioning to end point at the specified circular
interpolation.
(3) The radius-specified circle specifies circular interpolation method connected start
point and end point at the seeing on the plane for which performs circular
interpolation.
(4) A less than half-circle circular arc command is given at a positive R (circular arc
radius) value, or a more than half-circle circular arc command is given at a
negative R value. Always use an incremental value to command the R value.
(5) The travel speed is the specified combined-speed for 2 axes circular interpolation
axis.
(6) If a complete round command (the start point is the same as the end point) is
specified in R-specified helical interpolation, a minor error will (error code : 108)
occur and no operation is performed. Therefore, specify the helical circular arc
central coordinates for the complete round command.
The linear interpolation to other linear axis is executed performing 2
axes circular interpolation from the current position (start point) to
circular interpolation axis end point address or linear axis end point
address, and the helical interpolation (CW) is executed so that it may
become a spiral course.
The travel speed is the specified combined-speed for 2 axes circular
interpolation axis.
