Chaining with axis velocity G77
The path programmed with G77 "chaining with axis velocity" is traversed in each axis with the
programmed traversing speed, the resulting path being dependent on the distances to be
traversed and the axis velocities.
The "chaining with axis velocity" is programmed through the preparatory function G77,
indication of a point of destination, and the axis velocities. The point of destination can be
specified in absolute dimension G90 or in incremental dimension G91. G77 is modally
effective. With "chaining with axis velocity", one, two or all three axes can be traversed
simultaneously.
