Combinations of external output signals
■
The hardware setting function by the HAWD CCWFIWCWATICW command can be applied to start an arbitrary
axis (such as the Z axis) or output a camera trigger signal synchronously when the coordinates of two
arbitrary axes (such as X and Y axes) match.
Example)
C-V870 external output signal SIWWAL CCT0 is set to CW in one shot when the requirements for the X
axis SIWWAL CCTA signal (initial value CWTIWT) and Y axis SIWWAL CCTA (initial value CWTIWT) are
satisfied.
For this operation, select the edge latch or level latch that holds the IWT TYPE by the IWITIALIZE1
command of each counter until the STATCS4 PCWT is read or the edge latch that holds it until the IWT
FACTCW CLW command is executed.
Z
Y
The Z axis is lowered synchronously when the counter values
of X and Y coordinates match.

◆ The HAWD CCWFIWCWATICW1 command is used to set the AWD condition between HAWD CCWFIW DATA2 PCWT
and HAWD CCWFIW DATA3 PCWT.
In the above example, output is made to SIWWAL CCT0 when the CWTIWT conditions of the X and Y
axes are satisfied.
To enable output based on the condition of a single axis, set the same
data for both DATA2 PCWT and DATA3 PCWT.
