What is the purpose of the RUN instruction in a FANUC robot?

The purpose of the RUN instruction in a FANUC robot is primarily related to enabling multi-tasking capabilities. When the RUN instruction is executed, it allows the robot to simultaneously manage multiple tasks and programs. This means that the robot can handle several operations at once, coordinating different processes effectively without needing to pause or stop to switch between them.

In the context of robotic operations, multi-tasking is crucial for maximizing efficiency and optimizing workflow, particularly in environments where repetitive and complex tasks need to be executed seamlessly. By incorporating the RUN instruction, the FANUC robot can enhance productivity and provide more flexible automation solutions.

While the other options touch on different functionalities, they do not accurately encompass the capabilities that the RUN instruction brings to a FANUC robot's operational framework. Stopping all tasks, single-task programming, and debugging are important aspects but are not the primary function of the RUN instruction, which is centered on enabling levels of operation that involve running multiple tasks concurrently.
