How frequently is collision guard sensitivity updated?

Collision guard sensitivity in FANUC systems can indeed be updated as often as the programmer decides. This means that the programmer has the flexibility to assess the working environment and adjust the sensitivity settings as needed during the programming process. This adaptability allows for real-time optimization of the collision prevention measures based on specific operational scenarios or changes in the workspace, enhancing safety and efficiency.

The ability to update sensitivity at any point empowers the programmer to respond to varying conditions such as tool changes, workpiece adjustments, or modifications in the setup. This capability is essential for maintaining operational safety and minimizing the risk of collisions, which could potentially lead to equipment damage or safety hazards.

In contrast, other options imply a more limited frequency of updates, such as only at the start or end of a program, which would not provide the same level of responsiveness to dynamic work environments. Thus, the correct choice reflects the flexibility and control that operators have over their machining processes.
