9. Miscellaneous Functions
Program end : M02 or M30
This command is normally used in the final block for completing the machining, and so it is
primarily used for tape rewinding. Whether the tape is actually rewound or not depends on the
machine specifications. Depending on the machine specifications, the system is reset by the M02
or M30 command upon completion of tape rewinding and any other commands issued in the same
block.
(Although the contents of the command position display counter are not cleared by this reset action,
the modal commands and compensation amounts are canceled.)
The next operation stops when the rewinding operation is completed (the in-automatic operation
lamp goes off). To restart the unit, the automatic start button must be pressed or similar steps must
be taken.
(Note 1) Independent signals are also output respectively for the M00, M01, M02 and M30
commands and these outputs are each reset by pressing the reset key.
(Note 2) M02 or M30 can be assigned by manual data input (MDI). At this time, commands can be
issued simultaneously with other commands.
Macro interrupt : M96, M97
M96 and M97 are M codes for user macro interrupt control.
The M code for user macro interrupt control is processed internally, and is not output externally.
To use M96 and M97 as a miscellaneous code, change the setting to another M code with the
parameter (#1109 subs_M and #1110 M96_M, #1111 M97_M).
Subprogram call/completion : M98, M99
These commands are used as the return instructions from branch destination subprograms and
branches to subprograms.
M98 and M99 are processed internally and so M code signals and strobe signals are not output.
Internal processing with M00/M01/M02/M30 commands
Internal processing suspends pre-reading when the M00, M01, M02 or M30 command has been
read. Indexing operation other than M02/M03 and the initialization of modals by resetting differ
according the machine specifications.
