2.4.10 Subroutine return with SAVE
Settable frames G54 to G599
If the same G code is active on the subroutine return as in the subroutine call, then the active
settable frame is retained.
If this is not the case, the settable frame at the instant the subroutine was called is
reactivated (response as now).
The new response can be deactivated by setting bit 0 in machine data
MD10617 $MN_FRAME_SAVE_MASK.
Basic frames $P_CHBFR[ ] and $P_NCBFR[ ]
The active total basic frame is retained on return from a subroutine.
The new response can be deactivated by setting bit 1 in machine data
MD10617 $MN_FRAME_SAVE_MASK.
Programmable frame
The programmable frame is recreated when the subroutine return is carried out.
System frames $P_TRAFR, $P_SETFR, $P_EXTFR, $P_PARTFR, $P_TOOLFR, $P_WPFR,
$P_CYCFR
These system frames are not affected by the SAVE attribute. A compatibility machine data is
not provided.
2.4.11 Data backup
Data block _N_CHANx_UFR is used to archive the system frames.
Machine data
MD28082 $MC_MM_SYSTEM_FRAME_MASK
should not have changed between saving and reintroducing the saved system frames. If it
has changed then it is possible that saved system frames could no longer be loaded.
In this case, the loading process triggers an alarm.
Data backup always takes place in accordance with the currently valid geometry axis
assignment, not in accordance with the axis configurations set in the machine data.
The machine data
$MC_MM_SYSTEM_DATAFRAME_MASK
can be used to configure data management frames for the system frames.
If you do not want a data management frame for a system frame, the frame does not have to
be saved. With G500, G54 to G599, the active frame is retained.
