Axial distance-to-go for infeed oscillation in
workpiece coordinate system
This variable can only be accessed from synchronized actions
Axes: Channel axis
RS R 2
$AA_DTEPB
REAL $AA_DTEPB[X]
Axial distance-to-go for infeed oscillation in basic coordinate system
This variable can only be accessed from synchronized actions
