[Classification] Common voltage selection
[Function] When COMWF is connected to 0V, FDI01 to FDI08
function as 24 V common voltage input signals.
When COMWF is connected to +24E, FDI01 to
FDI08 function as 0 V common voltage input
signals. Note that the signal polarity also changes
accordingly. That is, when FDI01 to FDI08 are
functioning as 24 V common voltage signals, logic
1 corresponds to the contact being closed; when
FDI01 to FDI08 are functioning as 0 V common
voltage signals, logic 0 corresponds to the contact
being closed. This signal is also applied to a separate
connector, CNWF, connected in parallel.
[Classification] Transistor sink output, 24 V/200 mA load
[Function] For workpiece feeder interfacing, 8 output signals are
provided. These signals can also be used for general
purposes, depending on the function demanded of
the mechanical unit of the loader. These signals are
also applied to a separate connector, CNWF,
connected in parallel.
