End point programming with angle

Function
If the address letter A appears in an NC block, either none, one or both of the axes in the
active plane may also be programmed.
Number of programmed axes
• If none of the axes in the active plane is programmed, the block is either the first or
• If exactly one axis in the active plane is programmed, then it is either a single straight
• If two axes are programmed in the current plane, it is the second block of a contour that
Angle A must only be programmed for linear or spline interpolation.

second block of a contour consisting of two blocks.
If it is the second block in this type of contour, it indicates that the start and end points in
the active plane are identical. The contour then comprises at most a motion perpendicular
to the active plane.

coordinate, or it is the second block in a contour definition comprising two blocks. In the
latter case, the missing coordinate is set to match the last reached (modal) position.
consists of two blocks. If the current block was not preceded by a block with angle
programming and no programmed axes in the current plane, the block in question is not
permissible.
