T** $$
-l-T
L—
Offset number (Wear offset )
01 to 16/01 to 49 (TooI nose R)
(Tool coordinate memory number)
1,
Tool number
01 to 16/01 to 49
Note :
The tool coordinate memory number is:
(offset number + 50).
Thus, the tool coordinate
memory value selects the contents of (offset
number + 50) .
(a)
(b)
(c)
By executing the T**$$ command, the turret
is called wherever the tool post is located,
and is moved for the offset amount of the
offset number, to execute the coordinate
system setting corresponding to the selected
tool coordinate memory number.
By executing the T**OO command, the turret
is called wherever the tool post is located,
and the offset amount cancel movement is
executed.
No coordinate system setting is
performed.
The tool nose coordinate system is always set
by the coordinate system setting.

NOTES WHEN USING THE CONVENTION-
AL G50T **** FUNCTION
When using the coordinate system setting
specification, do not give the G50 T**** command.
Error will occur if commanded.

MISCELLANEOUS FUNCTIONS (M-FUNCTION)
The miscellaneous function is specified with the
address M and a maximum 3 digits.
The function
of each M code (MOO to M99) is determined by the
machine, except for several M codes.
Refer to
the machine tool builder’s manual for the func-
tion of M codes except for-the following M codes
concerned with the control.
2.7.
I M CODES FOR STOP (M 00, M 01, M 02, M 30)
To stop the NC control and machine, the following
codes are provided.
MOO:
Program stop
MO1:
Optional stop
M02:
End of program
M30:
End of tape
These commands stop the advance reading of the
control. For these M codes, M 2–digit BCD code
and their respective decoded signals are output.
2.7.2 M CODES FOR INTERNAL PROCESSING
(M 90 TO M 109)
M90 through M109 are for internal processing.
Even when they are programmed, no external
output signal (BCD and decoded output) is sent.

M97 ‘:

2.7.3 BUFFERING FUNCTION (M 93, M 92)+
(1)
(2)
(3)
The following M codes are issued for
buffering function.
t
M93 I 4-tIlock buffering
Note: When power is applied the current M code is changed
to the M code maked wirh~. However, it is not changed by
RESET operation.
4-block buffering (M 93)
When M93
; command is given, the control
enters the 4-block buffering mode, which
remains until M92 is commanded subsequent-
ly .
In this mode, up to 4 blocks of data
are read in advance for subsequent opera–
tion.
With programs in which the operation
time for the 4 blocks read in advance is
longer than the reading and processing time
of the subsequent 4 blocks, interruption
between blocks can be eliminated. This
function is effective in avoiding a shiny
streak on the workpiece caused by feed
stop between blocks .
1-block buffering (M92)
When M92 command is given,
buffering mode is cancelled,
buffering mode is restored.
Note :
While the tool radius is
the 4-block
and the 1 block
being compensated
for with the M93 function , up to two blocks not
containing move commands ar-e permitted , and as
the result, up to 6 blocks may be read in advance.
