Example
No infeed must take place at reversal point 1. At reversal point 2, the infeed is to start at a
distance of ii2 before reversal point 2 and the oscillating axis is not to wait at the reversal point
for the end of the partial infeed. Axis Z is the oscillation axis and axis X the infeed axis.

Program code Comment
DEF INT ii2 ; Define variable for reversal area 2
OSP1[Z]=10 OSP2[Z]=60 ; Define reversal points 1 and 2
OST1[Z]=0 OST2[Z]=0 ; Reversal point 1: Exact stop fine
Reversal point 2: Exact stop fine
FA[Z]=150 FA[X]=0.5 ; Oscillating axis Z feedrate, infeed axis X feedrate
OSCTRL[Z]=(2+8+16.1) ; Deactivate oscillating motion at reversal point 2; after
delete DTG spark-out and approach end position; after de-
lete DTG approach reversal position
OSNC[Z]=3 ; Sparking-out strokes
OSE[Z]=70 ; End position = 70
ii2=2 ; Set reversal point range
WAITP(Z) ; Enable oscillation for Z axis
2. Synchronized action
Program code Comment
WHENEVER $AA_IM[Z]<$SA_OSCILL_REVERSE_POS2[Z]
DO ->
$AA_OVR[X]=0 $AC_MARKER[0]=0
; If the actual position of oscil-
lating axis Z in MCS is less than
the start of reversal range 2, then
always set the axial override of the
infeed axis X to 0% and the bit mem-
ory with index 0 to the value 0.
