If a problem occurs, first enter the QuickOpen window of the LVSON command, and then click the [Check] button.

If tracking is not performing properly at the welding site, the following reasons can be considered.

 

(1)   Excessive spatter or welding light

Design the casing well such that the sensor can be less sensitive to welding light and spatter.

Use airblow.

Check whether the seam is recognized by the sensor controller during welding.

 

(2)   See whether the seam position that is inputted into the sensor is different from the desired seam position.

In this case, set the seam in the sensor controller, store the seam in the sensor, and then carry out testing.

 

(3)   See whether the sensor does not detect the seam.

Check if seam registration and seam number setting have been properly performed.

Check the real-time sensing screen during welding.

Adjust the values such as mismatch, gap, angle, and laser intensity.

 

(4)   Communication errors

Inspect the sensor and sensor controller, robot controller’s IP, port, and cables.

 

(5)   Problem with control gain

P gain 15, 15 / D gain 15, 15 is the basic value.
