7.1.2 Acquisition frame rate
With Trigger OFF (free running mode – see section 7.2.1), the default frame rate of the camera is
based on the specified ROI. The smaller the ROI, the faster the default frame rate. However, it is
possible to specify a free-running frame rate (i.e., no trigger needed) that is slower than the
default rate. This can be useful when a longer exposure time is needed for a specific ROI.
Modification of the frame rate is done by entering a value in the AcquisitionFrameRate control
corresponding to the frame frequency. Allowed values range from 6999 Hz to 0.125 Hz (
µ
s) for
SP-5000-GE2, however if the value entered is less than the time required for the default frame rate,
the setting is ignored and the default frame rate is used. For example, the minimum frame period
for the smallest possible ROI (8 lines) requires 6999 Hz (fps)(8-bit, LAG), so any entry more than
6999
Hz (fps) will always be ignored.
The setting range in Acquisition Frame Rate is:

to
Longest
Inverse number of time

to
0.125 Hz (fps) = 8 seconds
For the above setting, Acquisition Frame Rate is used and its unit is Hz (fps).
Acquisition Frame Rate: 6999 Hz (fps) to 0.125 Hz (fps)
7.1.3 Calculation of frame rate
The actual frame rate is the smaller one between the sensor output frame rate and frame rate of
network bandwidth.
If frame rate of network bandwidth is smaller than sensor output frame rate,
sensor output frame rate is automatically adjusted to match frame rate of network bandwidth.
The calculation formula for each frame rate is the following.
