skip signal. When the skip function is not used,
FDI08 can also be used for any purpose. The signals
are connected in parallel to another connector
CNWF.
Classification : Common selection
Function : When COMWF is connected to 0 V, FDI01 to FDI08
become common 24–V input signals. When
COMWF is connected to +24 V, FDI01 to FDI08
become common 0–V input signals. The signal
polarity changes accordingly. When FDI01 to FDI08
are used as common 24–V signals, a closed contact
makes the signals go to logical 1. When they are used
as common 0–V signals, a closed contact makes the
signals go to logical 0.
These signals are connected in parallel to another
connector CNWF.
Classification : 24–V source output, 24–V/200–mA load
Function : These eight output signals are provided as an
interface with a workpiece feeder. The signals can be
used for any purpose related to the mechanical unit.
The signals are connected in parallel to another
connector CNWF.
The emergency stop control circuit of the loader I/O board is based on the
emergency stop control circuit on the loader control board of the Series
16/18–MODEL A/B/C.
For details of the emergency stop control circuit, see also Section 2.6.
