13. INPUT/OUTPUT OF DATA
B–64113EN–1/01
910
By using the external program input start signal, a program can be loaded
from an input unit into CNC memory.
When an input unit such as the FANUC Handy File or FANUC Floppy
Cassette is being used, a file can be searched for using the workpiece
number search signals, after which the program can be loaded into CNC
memory.
To use external program input start signal MINP <G058#0> to start data
input, the following conditions must be satisfied:
D The reader/punch interface function is enabled.
D Bit 7 (MIP) of parameter No. 3201 is set to 1.
D Programs are not protected using the memory protection signal.
D Automatic operation mode is set.
D The current state is other than the start of automatic operation, that is,
cycle start lamp signal STL is set to 0. (Automatic operation signal
OP may be set to 1.)
[Classification] Input signal
[Function] This signal starts the loading of a program from an input unit into CNC
memory.
[Operation] When the signal is set to 1, the control unit operates as follows:
D When memory operation mode is set, but no automatic operation is
being performed and program loading is not inhibited by the setting
of the memory protection key, the CNC deletes all currently loaded
programs, then loads a program from the external input unit into CNC
memory.
D When the FANUC Handy File or FANUC Floppy Cassette is being
used as the input unit, a desired file can be searched for using the
workpiece number search signals (PN1 to PN16), after which the
program can be loaded into CNC memory.
File numbers are indicated using the workpiece number search signals,
as follows:
Workpiece no. search signal
PN16 PN8 PN4 PN2 PN1
