Non-Modal Oscillation (Starting Position = Reversal Point 1) - Siemens SINUMERIK 840D sl Function Manual

Program code
WAITP(Z)
M30
Description
When the Z axis starts oscillation, it first approaches the starting position (position = -50 in the
example) and then begins the oscillation motion between the reversal points -10 and 30. When
the X axis has reached its end position 30, the oscillation finishes at the next approached
reversal point.

Comment
Comment
; Oscillation with synchronized actions,
; start position == reversal point 1
; explain reversal points 1 and 2
; Reversal point 1: Exact stop coarse
; Reversal point 2: Exact stop fine
; Infeed for oscillating axis,
; feedrate for infeed axis
; switch off oscillation motion at
; reversal point 1 after DTG spark-out
; and approach end position
; After DTG, approach relevant
; reversal position
;
; 3 sparking-out strokes
; End position = 0
; Start position = 10
; enable oscillation for the Z axis
the marker with index 2 equals 0
and the current position of the oscillating axis
does not equal the reversal position 1
set the marker with index 1 to 0.
