$P_IFRAME=$P_UIFR[0] corresponds to G500
$P_IFRAME=$P_UIFR[1] corresponds to G54
$P_IFRAME=$P_UIFR[2] corresponds to G55
$P_IFRAME=$P_UIFR[3] corresponds to G56
$P_IFRAME=$P_UIFR[4] corresponds to G57
You can change the number of frames with machine
data:
$P_IFRAME=$P_UIFR[5] corresponds to G505
... ... ...
$P_IFRAME=$P_UIFR[99] corresponds to G599
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
G54, G55, ...
