B–63523EN–1/03
1854
Using the EPN0 to EPN13 (expanded external workpiece number search)
signals enables a search for program numbers O0001 to O9999.
Unlike the workpiece number search signal, which triggers an automatic
operation after a program search, these signals can make a program search
without triggering an automatic operation, because they can be used with
the EPNS (expanded workpiece number search start) signal.
[Classification] Input signal
[Function] These signals specify the number of the program to be executed in the
memory mode, using a binary code. The program numbers that can be
specified by these signals range from 1 to 9999.
(Program number 0 is used to make the special specification that ”no
search is to be made.”
These signals are valid if the EPN parameter No. (bit 1 of parameter No.
3006) is 1.
If the EPN parameter (bit 1 of parameter No. 3006) is 0, the conventional
workpiece number search signals PN1, PN2, PN4, PN8, and PN16
<G0009#0 – #4) are valid.
[Classification] Input signal
[Function] This signal causes the workpiece number search function to be executed
without performing an automatic operation. When the signal changes
from 1 to 0, a search is executed.
Setting the EPS parameter (bit 2 of parameter No. 3006) enables the
EPNS signal and disables the conventional search function that is based
on the ST (cycle start) signal.
