M30 (end of tape)
Normally, M30 is specified at the end of tape. When M30 is executed during auto-
matic operation, automatic operation ends after the commands specified with M30
in the same block have been completed. The NC is reset and the tape is rewound.
The state after the execution of M30 varies with each machine. For details, refer to
the instruction manuals published by the machine tool builder.
Note
When M00, M01, M02, or M30 is specified, the NC stops buffering. For these
M codes, the NC output the independent decode signal in addition to the M2-digit
BIN code.
Note
Refer to the manuals published by the machine tool builder concerning whether or
not the spindle and/or coolant supply is stopped by the M00, M01, M02, and M30.
