Description: System variable/value range/index
$AC_PATHN
Normalized path parameter
value between 0=start of block and 1=end of block
This variable can only be accessed from synchronized actions
$AC_DTBW
Geometric distance from start of block in workpiece coordinate
system
The programmed position is decisive for computing the distance; if
the axis is a couppling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
$AC_DTBB
Geometric distance from start of block in basic coordinate system
The programmed position is decisive for computing the distance; if
the axis is a couppling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
$AC_DTEW
Geometric distance from end of block in workpiece coordinate system
The programmed position is decisive for computing the distance; if
the axis is a couppling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
$AC_DTEB
Geometric distance from end of block in basic coordinate system
The programmed position is decisive for computing the distance; if
the axis is a couppling axis, the position part that results from axis
coupling is not considered here.
This variable can only be accessed from synchronized actions
$AC_PLTBB
Path distance from start of block in basic coordinate system
This variable can only be accessed from synchronized actions
$AC_PLTEB
Path distance from end of block in basic coordinate system
This variable can only be accessed from synchronized actions
$AC_DELT
Unlatched residual path distance in workpiece coordinate system
after
delete distance-to-go with motion-synchronized actions
$P_APDV
Returns True if the positional values which can be read with
$P_APR[X] or $P_AEP[X]
(the start point or contour point for soft approach and retraction) are
valid.
