(2) Internally Processed M Codes
M codes in the range of M90 to M99 and M190 to M199 are processed by the NC internally
and the corresponding output signal (BIN code and decode output) is not output even when
these M codes are executed.
Table 3.5.3.1 Internally Processed M Codes
Note 1: M190 to M199 are used for extension M codes.
2: When the power is turned ON, the M code mode indicated by “°” symbol is set. This is not
influenced by the reset operation.
(3) Other General M Codes
The functions of the M codes other than the specific M codes are determined by the machine tool builder. The representative use
of several general M codes is given below. For details, refer to the instruction manuals published by the machine tool builder.
If an M code is specified with axis move commands in the same block, whether the M code is executed with the axis move
commands simultaneously or it is executed after the completion of the axis move commands is determined by the machine tool
builder. For details, refer to the instruction manuals published by the machine tool builder.

M Code Function Remarks
M03 Spindle start, forward direction
Generally, M state between M03 and M04
cannot be switched directly. To change the
M code state, execute M05 once.
