$P_PFRAME
Current programmable frame
$P_PFRAME is the programmable frame resulting
from the programming of TRANS/ATRANS,
G58/G59, ROT/AROT, SCALE/ASCALE,
MIRROR/AMIRROR or the assignment of CTRANS,
CROT, CMIRROR, CSCALE to the programmable
FRAME.
Current, programmable frame variable that
establishes the reference between the settable zero
system (SZS) and the workpiece coordinate system
(WCS).
$P_ACTFRAME
The current resulting total frame $P_ACTFRAME
results from the chaining of all base frames, the
current settable frame and the programmable frame.
The current frame is always updated if a frame
element is modified.
$P_ACTFRAME corresponds to $P_ACTBFRAME : $P_IFRAME : $P_PFRAME
