G10 L2 P0 Ext. zero offset --> base frame $P_CHBFRAME[0]S
To uncouple the concerned frames between the Siemens and the ISO modes, four
new system frames are provided: $P_ISO1FRAME to $P_ISO4FRAME. The fra-
mes are created with the machine data 28082: $MC_MM_SY-
STEM_FRAME_MASK, bits 7 to 10. The reset behavior is set using the machine
data 24006: $MC_CHSFRAME_RESET_MASK, bits 7 to 10.
Fig. 3-5 shows the G codes in the ISO mode and the assignment of the frames if
the system frames $P_ISO1FRAME to $P_ISO4FRAME, $P_SETFRAME and
$P_EXTFRAME are created.
