Coordinate transformation (FRAMES)
5.2 Frame variables / assigning values to frames
Syntax
Assigning frames
DEF FRAME SETTING1
SETTING1=CTRANS(X,10)
$P_PFRAME=SETTING1
DEF FRAME SETTING4
SETTING4=$P_PFRAME
$P_PFRAME=SETTING4
Frame chains
The frames are chained in the programmed sequence. The frame components (translations,
rotations, etc.) are executed additively in succession.
$P_IFRAME=$P_UIFR[15]:$P_UIFR[16]
$P_UIFR[3]=$P_UIFR[4]:$P_UIFR[5]
Note
The frames must be linked with each other using the concatenation colon : .
302
Assign the values of the user frame
SETTING1 to the current programmable
frame.
The current programmable frame is
stored temporarily and can be
recalled.
$P_UIFR[15] contains, for example,
data for zero offsets. The data of
$P_UIFR[16], e.g., data for rotations,
are subsequently processed additively.
The settable frame 3 is created by
chaining the settable frames 4 and 5.
