11.1 Coupled motion (TRAILON, TRAILOF)
Comment
; Activation of 1st coupled axis grouping
; Activation of 2nd coupled axis grouping, Negative
coupling factor: Coupled-motion axis traverses in the
opposite direction from leading axis.
; Infeed of Z and W axes in opposite axial directions.
; Infeed of Y and V axes in same axis direction.
; Overlaying of a dependent and independent movement of
coupled motion axis V.
; Deactivation of 1st coupled axis grouping.
; Deactivation of 2nd coupled axis grouping.
