Coordinate transformation (FRAMES)
5.1 Coordinate transformation via frame variables
Assignment to G commands
As standard, five settable frames

$P_IFRAME=$P_UIFR[0]
$P_IFRAME=$P_UIFR[1]
$P_IFRAME=$P_UIFR[2]
$P_IFRAME=$P_UIFR[3]
$P_IFRAME=$P_UIFR[4]
You can change the number of frames with machine data:
$P_IFRAME=$P_UIFR[5]
... ... ...
$P_IFRAME=$P_UIFR[99]
Note
This allows you to generate up to 100 coordinate systems, which can be called up globally in
different programs, for example, as zero point for various fixtures.
Frame variables must be programmed in a separate NC block in the NC program.
Exception: programming of a settable frame with
