6-30 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
$P_CHBFRMASK can be used to define which channel-specific basic frames are included,
and $P_NCBFRMASK can be used to define which NCU-global basic frames are included in
the calculation.
When the variables are programmed, the total basic frame and the total frame are calculated
again. After a reset and in the default setting, the value of
$P_CHBFRMASK = $MC_CHBFRAME_RESET_MASK and
$P_NCBFRMASK = $MC_CHBFRAME_RESET_MASK.
e.g.,
$P_NCBFRMASK = 'H81' ;$P_NCBFRAME[0] : $P_NCBFRAME[7]
$P_CHBFRMASK = 'H11' ;$P_CHBFRAME[0] : $P_CHBFRAME[4]
$P_IFRAME Current settable frame
The predefined frame variable $P_IFRAME can be used to read and write the current
settable frame, which is valid in the channel, in the parts program. The written settable frame
is immediately included in the calculation.
In the case of NCU-global settable frames, the modified frame acts only in the channel in
which the frame was programmed. If the frame is to be modified for all channels of an NCU,
$P_UIFR[n] and $P_IFRAME must be written simultaneously. The other channels must
then activate the corresponding frame, e.g., with G54.
$P_PFRAME Current programmable frame
$P_PFRAME is the programmed frame that results from the programming of
TRANS/ATRANS, G58/G59, ROT/AROT, SCALE/ASCALE, MIRROR/AMIRROR or from the
assignment of CTRANS, CROT, CMIRROR, CSCALE to the programmed FRAME.
Current, programmable frame variable that establishes the reference between the settable
• zero system (SZS) and the
• workpiece coordinate system (WCS)
.
P_ACTFRAME Current complete frame
The resulting current complete frame $P_ACTFRAME is now a chain of all basic frames, the
current settable frame and the programmable frame. The current frame is always updated
whenever a frame component is changed.
$P_ACTFRAME corresponds to
$P_PARTFRAME : $P_SETFRAME : $P_EXTFRAME : $P_ACTBFRAME : $P_IFRAME :
$P_TOOLFRAME : $P_WPFRAME : $P_TRAFRAME : $P_PFRAME : $P_CYCFRAME
