Tool function (T function)

The tool function has various command designation types. For details, refer to the
instruction manuals published by the machine tool builder.
3.6.3

Miscellaneous function (M function)

The miscellaneous function is specified by a maximum of a three-digit number
(Mjjj) following address M. With the exception of specific M codes, the func-
tions of M00 to M89 codes are defined by the machine tool builder. Therefore, for
details of the M code functions, refer to the instruction manuals published by the
machine tool builder.
The M codes specific to the NC are described below.
M codes relating to stop operation (M00, M01, M02, M30)
When an M code relating to stop is executed, the NC stops buffering. Whether
spindle rotation, coolant discharge or another operation stops in response to the
execution of such an M code is determined by the machine tool builder. For details,
refer to the instruction manuals published by the machine tool builder. For these M
codes, a code signal is output independently in addition to M2-digit BIN code.
M00 (program stop)
If M00 is specified during automatic operation, automatic operation is interrupted
after the completion of the commands specified with M00 in the same block and
the M00R signal is output. The interrupted automatic operation can be restarted by
pressing the cycle start switch.
M01 (optional stop)
If M01 is executed with the optional stop switch ON, the same operation as with
M00 is executed. If the optional stop switch is OFF, M01 is disregarded.
M02 (end of program)
M02 should be specified at the end of a program. When M02 is executed during
automatic operation, automatic operation ends after the commands specified with
M02 in the same block have been completed. The NC is reset. The state after the
end of a program varies with each machine. For details, refer to the instruction
manuals published by the machine tool builder.
