12.5.4 Examples for starting position
12.5.4.1 Define starting position via language command
WAITP(Z)
OSP1[Z]=10 OSP2[Z]=60
OST1[Z]=-2 OST2[Z]=0
FA[Z]=5000 FA[X]=2000
OSCTRL[Z]=(1+8+16,0)
OSNSC[Z]=3
OSE[Z]=0
OSB[Z]=0
OS[Z]=1 X15 F500
OS[Z]=0
WAITP(Z)
M30
Explanation
When the Z axis starts oscillation, it first approaches the starting position (position = 0 in the
example) and then begins the oscillation motion between the reversal points 10 and 60.
When the X axis has reached its end position 15, the oscillation finishes with 3 sparking out
strokes and approach of end position 0.
12.5.4.2 Start oscillation via setting data

$SA_OSCILL_VELO[ Z ] = 5000
$SA_OSCILL_IS_ACTIVE[ Z ] = 1
