[Cause]
Robot-generated grid calibration alarm. The taught model is too large compared with the search window. This may be due to the following reasons:
1. A search window smaller than the model has been created following the teaching model.
2. After teaching the model, the digital camera teaching screen was opened and the image size was reduced.
[Countermeasure]
Based on the reasons, the response is as follows:
1. Set the search window again to a range larger than the model.
2. Set the search window again according to the image size, and teach the model again.
