Description: System variable/value range/index
$AC_RETPOINT[X]
Reset point on the contour for reapproach
Axes: Channel axis
$AA_SOFTENDP[X]
Software limit position, positive direction
Axes: Machine axis
$AA_SOFTENDN[X]
Software limit position, negative direction
Axes: Machine axis
$AA_DTBW[X]
axial path from start of block in the workpiece coordinate system for
positioning and synchronized axes for motion synchronized action
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
$AA_DTBB[X]
Axial distance from start of block in basic coordinate system
for positioning and synchronized axes with motion-synchronized
actions
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
$AA_DTEW[X]
Axial distance to end of block in workpiece coordinate system
for positioning and synchronized axes with motion-synchronized
actions
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
$AA_DTEB[X]
Axial distance to end of block in basic coordinate system
for positioning and synchronized axes with motion-synchronized
actions
The programmed position is decisive for computing the path; if the
axis is a coupling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
Axes: Channel axis
