5.16 DNC OPERATION FROM OPEN CNC SELECTING SIGNAL
Overview
In DNC operation mode (DNC) or memory operation mode (MEM),
setting the DNC operation select signal from the open CNC to "1"
enables DNC operation and external memory subprogram calls from
the open CNC when parameter No. 0020 remains set to 16.
In other words, to use the open CNC, the foreground input device
setting using parameter No. 0020 has normally been required to switch
between 15 (for DNC operation) and 16 (for downloading). The use of
this signal enables DNC operation when parameter No. 0020 remains
set to 16 (download interface).
Signal
DNC operation select signal from the open CNC
DMMC<F042#7>
[Classification] Input signal
[Function] Specifies DNC operation and external memory subprogram calls from
the open CNC.
[Operation] When this signal is set to "1," the control unit operates as follows:
- Performs CNC operation from the open CNC when the CNC is in
DNC operation mode (DNC).
- Performs external memory subprogram calls from the open CNC
when the CNC is in memory operation mode (MEM).
To use this signal, set parameter No. 0020 to 16 (download interface
from the open CNC). If a value other than 16 is set, the input device is
selected according to the parameter setting.
When a mode other than DNC operation mode (DNC) or memory
operation mode (MEM) is selected, set this signal to "0."
