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
