Balluff - BVS CA-GX0 / BVS CA-GX2 Technical Documentation
BVS CA-GX0-0050ZG / mvBlueCOUGAR-X105G with frame rates < 5.75 Hz

Cause

The frame rate can not be reduced below 5.75fps because of some technical limitation related to the free running mode of the sensor.

Resolution

As soon as the sensor is used in triggered mode, the frame rate can be below 5.75 fps.

To get the camera working at lower frame rates, it is necessary to configure two timers which are used to trigger the sensor.

E.g., the camera is triggered at 4 fps.

  • Timer1 represents the duration of the "low" signal. It is configured to 240,000 us. TimerTriggerSource is configured to "Timer2End".
  • Timer2 represents the "high" signal. It is configured to 10,000us. TimerTriggerSource of Timer2 is "Timer1End". The sum of both durations is 250,000 us which means the sequence runs with 4 cycles per second. (1s/250,000us=4)

Afterwards the "TriggerSource" has to be configured to "Timer2Start" and the "TriggerMode" has to be switched to "On".

Once you start the acquisition by clicking the "Acquire" button, the camera should run at 4 fps.

To get the camera working at different frame rates, Timer1 needs to be configured accordingly. E.g. 500,000 us for 2 fps.
