12. AUTOMATIC OPERATIONPMC INTERFACE

NOTE
1 This function can be used only at automatic operation.
2 Always select the program number from O001 to O015.
3 Program numbers from O001 to O015 can be used.
However, programs corresponding to all the program
numbers do not have to be stored in memory.
4 When a program corresponding to the set program number
is not stored in memory, an alarm (No. 59) is generated
when the start button is pressed.
5 Program search is performed only when the start button is
pressed in the reset state. When the control unit is in the
feed stop state (single block stop, etc.) or feed hold state,
program search is not performed even if the start button is
pressed and execution is started from the point specified by
the present execution pointer.
6 To restart program from halfway, press start button after
sequence number search in MEM mode. The external
program number search is not performed and program
execution starts from the block which is searched by
sequence number search, because the OP signal outputs
by sequence number search in MEM mode and the NC
reset state is released.
7 When the start button is pressed with all PN0 to PN3 open,
program search is not performed but execution is started
from the point specified by the present execution pointer.
To restart operation from a point within a program or from the
start of a program which cannot be searched by this
function, perform the usual sequence number search or
program number search operation (MDI panel operation),
the turn off (open) all the PN0 to PN3 and press the start
button.
