If a move command and an M, S, or T command are specified in
the same block, the move operation and the M, S, or T operation are
executed simultaneously.

19.2.30 POSITIONING COMPLETION (DEN 1,2)
OUTPUTS
These outputs inform the completion of a move command when an
M, S, or T command and the move command have been specified
in the same block at the execution of a part program in the
automatic operation mode.
Tho block in whish an M, S, or T GOtIHtMItd and a move
command are specified at the same time is executed if the M, S, or
T command is not completed at the termination of the move
command, positioning completion outputs DEN1 and DEN2 are
closed.
When FIN input is closed then opened and the M, S, or T
command is completed, the positioning completion outputs are
opened.
19.2.31 TRAVEL ON (OPI ,2) AND THREAD CUTTING
ON (THC 1,2) OUTPUTS
(1) Travel ON (OP1, 2) 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 in any of the
following situations:
. During the execution of a move comand.
. In the state in which a move command is discontinued by the
interrupt (STLK) input or the FEEDHOLD (*SP) input.
(2) Thread Cutting ON (THC1, 2) Outputs
With these outputs, the control informs that thread cutting is
being performed during the execution of part program in the
automatic operation mode. These outputs are closed during
thread cutting.
19.2.32 END-OF-PROGRAM (EOP) INPUT, REWIND
(RWD) INPUT AND REWIND ON (RWDS1,2)
OUTPUTS
(1) End-of-Program (EOP) and Rewind (RWD) Inputs
With these outputs, the controller 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 M02R or M30R commands is opened and then closed:
In general, EOP input is connected to M02R output and RWD
input, to M30R output.

Program reset provides the same effects as with depressing of
RESET key on MDI panel (ERS) input. In the program reset,
however, the NC memory rewind operation is not perfomed. For
details of the rc.set operation by closin~ ERS input, refer to 19,2.24
“EXTERNAL RESET (ERS) INPUT AND RESET ON (RST 1, 2)
OUTPUT.”
When a program reset operation is perfomed, Reset On output RST
is closed for one second.
