2.8 MISCELLANEOUS FUNCTIONS
(M-FUNCTION)

The miscellaneous function is specified with the
address

and maximum three digits. The function

of each M code (MOO

M89) is

the machine, except for several M codes.

R e f e r

to the machine tool builder’s manual for the func-
tion of M codes except for the following M codes

concerned with the control.

2.8.1 M CODES FOR STOP (MOO, MO1 , M02,

MOO (Program Stop)

This code, when given in automatic operation
mode, stops the automatic operation after the
commands in the block containing MOO have
been completed and MOO R signal is fed. The

program may be continued

pressing the

CYCLE START button.

(Optional Stop)

performs the same function as program

stop MOO whenever the OPTIONAL STOP switch

is on.

When the OPTIONAL STOP switch is off,

the

code is disregarded.

M02 (End-of-Program)

is used at the end of program When

in automatic operation

mode , this code stops

the automatic operation after the commands in
the block containing M02 have been completed.
Although the control is reset in most cases,
the details are determined by the machine. Re-
fer to the machine tool builder’s manual.

M30 (End-of-Tape)

M30 is given at the end of tape. When given in
automatic operation mode, this code stops the
automatic operation after the commands in the

block containing M30 have been completed. In
addition, in most cases, the control is reset

and rewinds the memory.

Since the details

are determined by the machine, refer to the
machine tool builder’s manual.

Notes :

. When MOO, MO1, M02 or M30 is given, it pre-

vents the control from reading ahead the next
block of information.

The single decoded signal

is fed in addition to the 2-digit BCD output for
M

. Whether MOO, MO1, M02 or M30 executes spin-

dle stop , coolant off or some other executions,

refer to the machine tool builder’s manual.

2.8.2

M CODES FOR INTERNAL PROCESSING

(M90 TO Ml 99)

through Ml 99 are used only for internal pro-

c e s s i n g .

Even when they are programmed ,

external output signal

(BIN and decoded output)

is sent.
