Tool Life Control Function - Siemens SINUMERIK 802D sl Programming Manual

(The data bits are evaluated by the shell cycles)
S The M function to enable/disable the program interrupt function can be determi-
ned by machine data. However, M96, M97 is set as default.
$MN_EXTERN_M_NO_SET_INT: enable
$MN_EXTERN_M_NO_DISBLE_INT: disable
S In the program that is called up after interrupting the execution of another pro-
gram, it is not allowed to specify M97 or M96. If specified, an alarm occurs.
S The M96 command can be specified in a subprogram. Jump to an interrupt pro-
gram is not counted as a nesting level. Therefore, the level saved to the macro
local variable does not change.
S By the execution of M99 specified in the interrupt program, the program returns
to the block next to the one where the interrupt program has been called up. It is
also possible to specify the return block by specifying a P command with M99.
When returning to the previous program by the execution of M99, the modal
information which was valid before the interruption, is recovered. However, if
M99P_ is used to return to the previous program, the modal information chan-
ged during the execution of the interrupt program is used for the execution of
the previous program.
S If the interrupt signal is input during the block stop state, the program jumps to
the interrupt program when the operation is started by depressing of the cycle
start switch.
S The program interrupt signal is invalid if input during the execution of high-
speed cutting.
S If the program interrupt signal is input during the execution of G31 (skip), the
skip mode is canceled and the program interrupt function is executed.
S If the program interrupt signal is input during the execution of a block including
M, S, T, or B command, the program jumps to the interrupt program. Before
jumping to the interrupt program, axis move is stopped after deceleration if the
interrupt signal is input during axis move. If the M or T function is being execu-
ted when the interrupt signal is input, the program does not jump until the M or
T function completion signal is input.
S If the program interrupt signal is input during the execution of tapping in the so-
lid tap mode, execution of the interrupt program starts only after the completion
of the solid tap block.
