Oscillation (P5)
Oscillation controlled by synchronized actions
Example 1
Oscillation, reversal position firmly set via setting data:
$SA_OSCILL_REVERSE_POS1[Z]=-10
$SA_OSCILL_REVERSE_POS2[Z]=10
G0 X0 Z0
WAITP(Z)
ID=1 WHENEVER $AA_IM[Z] <
$SA_OSCILL_REVERSE_POS1[Z] DO
$AA_OVR[X]=0
ID=2 WHENEVER $AA_IM[Z] >
$SA_OSCILL_REVERSE_POS2[Z] DO
$AA_OVR[X]=0
OS[Z]=1 FA[X]=1000 POS[X]=40
OS[Z]=0
M30
Example 2
Oscillation with online change of the reversal position, i.e. any modification of reversal
position 1 via the user surface are immediately taken into account with active oscillation
movement.
$SA_OSCILL_REVERSE_POS1[Z]=-10
$SA_OSCILL_REVERSE_POS2[Z]=10
G0 X0 Z0
WAITP(Z)
ID=1 WHENEVER $AA_IM[Z] <
$$SA_OSCILL_REVERSE_POS1[Z] DO
$AA_OVR[X]=0
ID=2 WHENEVER $AA_IM[Z] >
$$SA_OSCILL_REVERSE_POS2[Z] DO
$AA_OVR[X]=0
OS[Z]=1 FA[X]=1000 POS[X]=40
OS[Z]=0
M30
