How can I increase the speed or Max Frame Rate of the Gocator?
|Sensor Model||G2xxx or G3XXX|
|Firmware Version||3.x, 4.x, 5.x, 6.x
Before beginning, a good rule of thumb is to spend some time analyzing what X,Y, and/or Z resolution that you need for your application measurements. If you do not yet know this, either consult an LMI representative or be sure to perform this analysis after achieving an acceptable frame rate. In many cases, customers may find that they have an X resolution that is very high compared to their Y-spacing, and therefore, they can achieve acceptable frame rates simply by balanching the X and Y spacing values.
After considering the measurement-based resolution requirements for the application, the Maximum Frame Rate can be improved by one or more of the following methods:
- Reduce the Active Area in the X and/or Z directions for G2 sensors or X, Y, and/or Z directions for G3 sensors
- Move the reduced Active Area towards the far end of the Measurement Range (this may require a slight mounting change to alter the sensor's proximity to the scanned object or vice versa. This could also negatively impact your X or XY Resolution)
- Optimize or reduce the overall exposure time(s)
- Change X or Z sub-sampling (Gocator 4.x), or Resolution X or Resolution Z (Gocator 3.x) to 1/2 or 1/4
- Reduce the Maximum Part Length (when in Surface scan mode)
- Increase the laser class of the sensor to leverage higher laser power and lower exposure (this will require a different physical unit)
Pay attention to CPU or CPU Load in the Metrics panel after adjusting any of these settings to ensure that the CPU load does not go too high. Also, verify that you are not experiencing any Processing or Trigger drops on the Dashboard page.
