What does a TP instruction with the motion option TB do?

The TP instruction with the motion option TB is used to set an output at a specific time prior to reaching a programmed location. This feature is particularly useful in scenarios where a particular operation or action needs to occur just before the robotic tool reaches its target position. By timing the output activation with the motion command, it ensures that processes such as gripping, welding, or signaling can occur precisely when needed, enhancing synchronization and efficiency in automated tasks.

In the context of automated processes, having the ability to trigger outputs at calculated points during motion is crucial, as it allows for better control over the sequence of events and interactions during operations. This capability is often utilized in complex applications requiring precision and timing, such as assembly lines or robotic welding.

The other options do not accurately describe the function of the TB motion option. Immediate stopping of motion, transferring power to tools, or changing tools involves different commands and functionalities that are not relevant to the specific task accomplished by the TB option.
