Infeed At Both Reversal Points - Siemens SINUMERIK 840D sl Function Manual

Programming
Reversal point range 2:
WHENEVER $AA_IM[Z] < $SA_OSCILL_REVERSE_POS2[Z] - ii2
DO $AA_OVR[X] = 0
Explanation:
$AA_IM[Z]: Current position of oscillating axis Z
$SA_OSCILL_REVERSE_POS2[Z]: Position of reversal point 2 of the oscillation axis
$AA_OVR[X]: Axial override of the infeed axis
ii2: Magnitude of reversal range 2 (user variable)
Infeed
The absolute infeed value is defined by instruction POSP.
See Chapter "Defining Infeed POSP".
Assignment
The assignment between the oscillation axis and the infeed axis is defined by instruction OSCILL.
See Chapter "Assignment of Oscillating and Infeed Axes OSCILL".
12.3.3

Infeed at both reversal points

General procedure
The functions described above for infeed at the reversal point and in the reversal point range
can be freely combined.
Combinations
Infeed:
to U1 - to U2
to U1 - range U2
range U1 - to U2
range U1 - range U2
One-sided infeed
to U1
to U2
range U1
range U2
These options are described in the chapter "Infeed in Reversal Point 1 or 2" and the chapter
"Infeed in the Reversal Range".
