20.2.26 TRAVEL ON (OP), TAPPING AND CANNED
CYCLE ON (G80S) Outputs
(1) Travel ON (OP) OUTPUTS
With these outputs, the control informs that the tool is traveling
during the execution of a part program in the automatic
operation mode. These outputs are closed when the machine
starts.
The output is turned off by RESET operation (including RESET
by M02, M30 command).
(2) Tapping (TAP) Output
With these outputs, the control informs that tapping is being
per-formed during the execution of part program in the
automatic ope-ration mode.
These outputs are given when tapping starts from point R to
point Z and turned off when tapping from point Z to point R is
completed.
(3) Canned Cycles (G80S) Output
This output indicates that the control is performing canned
cycles. The output G80S is given when canned cycle block
starts and turned off by canned cycle block cancellation.
20.2.27 END-OF-PROGRAM (EOP) INPUT, REWIND
(RWD) INPUT, AND REWIND ON (RWDS) OUTPUTS
(1) End-Of-Program (EOP) and Rewind (.RWD) Inputs
With these outputs, the control determines what processing is to
be performed at completion of an M02 or M30 command. The
control performs the following processing depending on the
state of EOP and RWD inputs when completion input FIN for
an M02 or M30 command is opened then closed:

1: Closed, O:Open
Notes :
1. Program reset provides the same effects as with pressing of
RESET key on MDI panel and the reset operation by closing
External Reset (ERS) input.
In the program reset, however, the NC memory rewind operation
is not performed.
2. Some parameters make resetting output RST "closed" for a
second at program resetting.
#6009 (D4)
When both RWD and
EOP are input or only EOP is input at
M02/M30:
1: RST output provided
O:RST output not provided
(2) Rewind ON (RWDS)
With these outputs, the control informs that the part program is
being rewound. If the part program is rewound by RWD input
for an M02 or M30 command, RWDS2 is closed during the
rewinding operation.
To use these outputs, set parameter #6007 D4 to '< 1." At "O,"
they are not given from the control.
20.2.28 EXTERNAL DATA INPUT (EDO THROUGH
ED15, EDSA THROUGH EDSD, EDSAO THROUGH
EDSA2, EDCL, EREND AND ESEND) lNPUTS/OUT-
PUTS
(1) These inputs/outputs are used to make the machine perform the
following functions by external inputs:
(a) External work number search
External inputting of 4-digit program (1 to 9999 BCD) selects
the work number desired.
(b) External tool compensation input
This external input signals can command compensation values
for tool length and diameter.
(c) External work coordinate system shift
The work coordinate system shift value can be entered
externally.
Externally entered axis correction value is added to the shift
value of the specified axis programmed by G54 to G59 and the
result is stored as a new shift vahte.
(2) Input/Output Signals for Inputting External Data
(a) External data inputs (EDO to ED15)
These inputs are used for work number input signal, offset
amount input signal snd work coordinate system shift signal.
