Active: Channel-specific programmable frame $P_PFRAME
The $P_PFRAME frame variable defines the reference between the settable zero system
(SZS) and the workpiece coordinate system (WCS).
$P_PFRAME contains the resulting frame, that results
● From the programming of TRANS/ATRANS, ROT/AROT, SCALE/ASCALE, MIRROR/
AMIRROR or
● From the assignment of CTRANS, CROT, CMIRROR, CSCALE to the programmed FRAME
Active: Total frame $P_ACTFRAME
The total frame active in the channel results from the chaining of all frames acting in the
channel.
$P_ACTFRAME =
$P_ACTFRAME describes the currently valid workpiece coordinate system.
