AUTO RESTART
[Function]
If this signal is turned ON after the end of the machining program execution, the same machining
program will be restarted.
[Operation]
The same machining program will restart if this signal is turned ON during automatic start.

Auto restart
(ARST)
*1:Rewind time during memory operation ...approx. 0.1 [s] + α (α is the PC cycle time)
*2:Refer to (Note 8).
(Note 1) The modal is initialized with this signal.
(Note 2) This signal is valid only during automatic start.
(Note 3) This signal is valid during the memory and MDI automatic operation modes.
(Note 4) Normally, the M02 or M30 single output signal is input into this signal, but in this case, do
not input the M02 or M30 completion signal (FIN1, FIN2).
(Note 5) If the automatic operation halt (*SP) signal is valid, the auto restart signal will be invalid.
(Note 6) This signal is invalid during single block stop.
(Note 7) Note that if an M command other than M02 or M30 is input into this signal, the program
will return to the start point without completing the program, and the program will be
restarted.
(Note 8) If reset & rewind (RRW) are applied during the auto restart process (*2 section in time
chart above), the modal will be initialized and the tape will be rewound, but the auto restart
signal will be invalid.
