External Program Number Search
A program number (1 to 9999) is specified from an extended source and is
selected in the CNC memory.
For machines that can load several kinds of workpieces, this function can
automatically select the program to be executed corresponding to a specific
workpiece.
Data for the external program number search is accepted regardless of CNC
mode, but the search execution can be made only in the reset state in MEM
mode.
The ESEND signal switches from “0” to “1” on completion of external
program number search. This signal does not turn to “0” unless the cycle
start or reset signal is input, or another search is made. Use ESEND to
initiate a cycle start signal after the search.
Because a search operation is deferred until a reset occurs in the MEM mode,
an external program number search attempted during a CNC operation (OP =
1) results in the program being started immediately after the end of an
automatic operation in a sequence in which the automatic operation is started
by checking only the ESEND signal (search completion signal for external
data input).
For this reason, using the ESC parameter (bit 3 of parameter No. 6300)
enables an external program number search to be canceled at a CNC reset.
Concretely, if a reset signal is input between the time the ESTB signal (read
signal for external data input) is input and the time a search would be
executed, setting the ESC parameter (bit 3 of parameter No. 6300) to 1 keeps
the search from being executed. At the same time, the controller uses the
ESCAN (search cancel signal for external data input) signal to inform the
PMC that the search has been canceled.
The ESEND signal (search completion signal for external data input) will
not become 1, because the search is canceled.
