6-2 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Possible frame variable:
• Basic frame (basic offset)
• Settable frames
• Programmable frame
Value assignments and reading the actual values
Frame variable/frame relationship
A coordinate transformation can be activated by assigning the value of a frame to a frame
variable.
Example: $P_PFRAME=CTRANS(X,10)
Frame variable:
$P_PFRAME means: current programmable frame.
Frame:
CTRANS(X,10) means: programmable zero offset of X axis by 10 mm.

Reading the actual values
The current actual values of the coordinate system can be read out via predefined variables
in the parts program:
$AA_IM[axis]: Read actual value in MCS
$AA_IB[axis]: Read actual value in BCS
$AA_IBN[axis]: Read actual value in BOS
$AA_IEN[axis]: Read actual value in SZS
$AA_IW[axis]: Read actual value in WCS
