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.

WAITP(Z)
STOPRE
$SA_OSCILL_REVERSE_POS1[Z]=-10 ; reversal position 1 = -10
$SA_OSCILL_REVERSE_POS2[Z]=30 ; reversal position 2 = 30
$SA_OSCILL_START_POS[Z] = -50 ; Start position = -50
$SA_OSCILL_CTRL_MASK[Z] = 512 ; Approach start position,
; on switch-off, stop at the next
; reversal point
; do not approach any end position
; no sparking-out strokes for DTG
