Stopping Automatic Operation
There are two means to stop the automatic operation.
One is to command a stop
command in a program where the execution is to be stopped (See 5.4.1 - 5.4.3) and
the other is to stop the operation at any time by pushing an appropriate button on the
operator’s panel (See 5.4.4 and 5.4.5).
54.1
Program stop (MOO)
Cycle operation is stopped after a block containing MOO is executed. When the
program is stopped, all existing modal information remains unchanged as in singie
block operation.
The cycle operation can be restarted by specifying an CNC start.
(This differs with the machine tool builder.)
54.2 Optional stop (MOl)
Similarly to MOO, cycle operation is stopped after a
This code is only effective when the Optional Stop
- panel is set to ON.
5.4.3
Program end (MO2, M30)
block containing MO1 is executed.
switch on the machine operator’s
(1)
This indicates the end of the main program and is necessary to store NC
commands from tape to memory.
(2)
Cycle operation is stopped and the NC unit is reset. (This differs with the
machine tool builder.)
(3)
Only M30
The control is rewound to the start of the program in AUTO operation. (This
differs with the machine tool builder. Some machines indicate rewind with
M02.)
5.4.4 Feed hold
When Feed Hold button on the operator’s panel is pressed during automatic operation,
the tool decelerates to a stop at a time.
