Why do I get Trigger Drop warnings in Encoder Trigger mode?
|Sensor Model||G1, G2 and G5
|Firmware Version||3.x, 4.x, 5.x and 6.x
There are a number of Gocator settings that determine how fast the sensor can run, such as Exposure, Active Area, Sub-Sampling (Gocator 4.x, 5.x and 6.x), or Resolution (Gocator 3.x). The maximum speed the sensor can run is displayed in the Trigger panel as the Max Frame Rate.
If the Gocator receives triggers from the encoder at a faster rate than the max frame rate, triggers will start to be dropped and a warning message is displayed.
As a solution, you might consider slowing down the movement to lower the frame rate of the encoder trigger or increase the spacing between acquired profiles. If the limitations come from the exposure time increasing the laser power by using a higher laser class or fine-tuning the Advance Settings such as camera gain might be a solution. Last but not least if the limitation is on the processing side (often with high-speed applications) then the GoMax or GoAcceleration can improve and resolve this issue.
Example: A Gocator is configured so that the max frame rate is 500 Hz. An encoder is monitoring the movement of a conveyor belt, which is going at a speed of 30 meters/minute. 30 m/min = 500 millimeter/second, so this means that the smallest trigger spacing the user can request is 1 mm, i.e., that's the 500 Hz. Anything below 1 mm will result in trigger drops.
