Trigger/Rate/Source/Strobe Selections
These selections refer to the fields labeled Focus Trigger , Rate per Minute ,
Focus Source I/O , and Focus Strobe I/O.
The description and procedures for making these selections and assignments
are the same as those described on page 3–45. The difference is that these
assignments apply only to the adjustment of the camera focus and lighting
resolution.
Shutter Speed Selection
The Shutter Speed field is active only when a frame reset camera type
(such as the 2801–YE), or a custom frame reset camera type, is selected. This
field enables access to the calculator pad, which is used to select a shutter
speed setting, in microseconds, for the 2801–YE (or other) frame reset
camera. The valid range for all cameras is 200 to 8000 microseconds.
Focus Function
When the auto/internal trigger source or a repeating external trigger source is
active, the focus function can capture a series of camera images, which
enables you to adjust the camera focus and aperture, and make the necessary
lighting and workpiece staging adjustments.
To enter the focus function, pick the button on the camera setup
panel. Figure 3.3 (page 3–6) illustrates the screen with the focus function
active.
NOTE: When using an external trigger source, if too much time elapses
between trigger pulses (about five seconds), system warning message #3072
appears on the display, as shown in Figure 3.4 (page 3–6). If you see this
message, you can either pick the
button to exit the focus function, or
you can pick the button to re–enable the focus function (when you
expect a trigger signal to occur within five seconds).
When you are finished with the focus function, pick the button in the
“ Focus ” box to return to the camera setup panel.
