[Cause]
This alarm occurs only on the instruction tool setup interface. If the target workpiece is not displayed, this alarm is not a problem. Otherwise, it may be caused by the following.
1. The measurement conditions for 3-dimensional points are unsuitable, and 3-dimensional point measurement failed.
2. The 3D points measured are all 3D points outside the visual program [measurement Z range].
[Countermeasure]
Please set the measurement conditions and [measured Z ranges] correctly. If 3D wide area sensors are used, set measurement conditions from 3D wide area sensor data. If a 3DV sensor is used, set from the distance image snapshot tool.
