Acquisition Control (Change the Frame Rate)

Related Setting Items:
With Trigger OFF (free-running mode), it is possible to specify a free-running frame rate (i.e., no trigger
needed) that is slower than the default rate.
The setting range in Acquisition Frame Rate is:
Inverse number of time required to drive all pixels in the area set by ROI command
Inverse number of time required to transmit one frame data
Notes:
When Trigger is set to Off, you cannot configure the Frame Rate setting.
l
If the value entered is less than the time required for the default frame rate, the setting is ignored and
l
the default frame rate is used.
When using Control Tool, the frame rate setting is configured by Acquisition Frame Rate (Hz). When
using ASCII Command (ART), the frame rate setting is configured by AcquisitionFrameTime (us).
For example, when Tap Geometry is set to 1X2-1Y and Camera Link Pixel Clock is set to 80Hz,
Acquisition Frame Rate: 7.8136 Hz to 0.125 Hz
l
AcquisitionFrameTime: 127982 μs to 8000000μs
l
For additional details, see
Mode.
Note: It is possible to set, for instance 7.8136 fps for 1X2–1Y, full frame and 80 MHz of Camera
Link pixel clock, but 7.8136 fps is the setting limit value. This value will vary depending on shutter
settings which will cause 1 H delay in conditions. 7.5 fps is the performance guaranteed value.
How to Configure
1. ROI should be set first.
2. The available number shown in Acquisition Frame Rate will correspond to the maximum frame period for
the specified ROI.
3. The value can be decreased up to 0.125Hz (fps).
