4. AUTOMATIC OPERATION
OPERATION

After AUTO operation is started, the following are executed:
(1) A one–block command is read from the specified program.
(2) The block command is decoded.
(3) The command execution is started.
(4) The command in the next block is read.
(5) Buffering is executed. That is, the command is decoded to allow
immediate execution.
(6) Immediately after the preceding block is executed, execution of the
next block can be started. This is because buffering has been
executed.
(7) Hereafter, AUTO operation can be executed by repeating the steps (4)
to (6).
AUTO operation can be stopped using one of two methods: Specify a stop
command, or press a key on the machine operators panel.
The stop commands include M00 (program stop), M01 (optional stop),
and M02 and M30 (program end).
There are two keys to stop AUTO operation: The feed hold key and
reset key.
AUTO operation is stopped after a block containing M00 is executed.
When the program is stopped, all existing modal information remains
unchanged as in single block operation. The AUTO operation can be
restarted by pressing the cycle start button. Operation may vary
depending on the machine tool builder. Refer to the manual supplied by
the machine tool builder.
Similarly to M00, AUTO operation is stopped after a block containing
M01 is executed. This code is only effective when the Optional Stop
switch on the machine operators panel is set to ON. Operation may vary
depending on the machine tool builder. Refer to the manual supplied by
the machine tool builder.
When M02 or M30 (specified at the end of the main program) is read,
AUTO operation is terminated and the reset state is entered.
In some machines, M30 returns control to the top of the program. For
details, refer to the manual supplied by the machine tool builder.
When Feed Hold button on the operators panel is pressed during AUTO
operation, the tool decelerates to a stop at a time.
Automatic operation can be stopped and the system can be made to the
reset state by using
RESET
key on the CRT/MDI panel or external reset
signal. When reset operation is applied to the system during a tool
moving status, the motion is slowed down then stops.
When the optional block skip switch on the machine operator’s panel is
turned on, blocks containing a slash (/) are ignored.
