5.2 Reading and writing of SD/MD from synchronized actions
Comment
; Equal to 0,
; Then set the axial override of the oscillating
; axis to 100% (so that the previous
; synchronized action is cancelled!)
; if the current position of the oscillating axis in the
; Workpiece coordinate system
; Equal to reversal position 1,
; Then set the axial override of the
; Oscillating axis to 100%
; and set the axial override of the
; infeed axis to 100% (so that the
; second synchronized action once
; is cancelled!)
Setting data, whose value may change during machining
(e.g. through an operator input or synchronized action),
must be programmed with $$S...:
Example: Oscillation from synchronized actions with
alteration of oscillation position via operator interface
; Always when the current position of the oscillating axis
; in the machine coordinate system
; Less the start of reversal area 2
than
; Then set the axial override of the
; infeed axis to 0
