What happens when a WAIT instruction is executed in a FANUC robot program?

• A. The robot pauses indefinitely
• B. Wait the robot to get to a specified PR[x]
• C. Resume from the last position without waiting
• D. Stop all motion immediately

Answer: (B)

When a WAIT instruction is executed in a FANUC robot program, the primary function of this command is to hold the execution of the program until a certain condition is met, which is often defined by the robot reaching a specified position register (PR[x]). This means that the robot will pause its operations and will only continue executing the program after it successfully arrives at the designated position. This behavior allows for precise control and synchronization in operations, particularly in scenarios where the robot needs to wait for specific events or movements to complete before proceeding. The option regarding the robot pausing indefinitely does not capture the conditional aspect of the WAIT instruction, as it specifically waits for a defined condition rather than leading to an indefinite pause. The resume from the last position without waiting option contradicts the purpose of the WAIT instruction, which is to ensure that the program execution is contingent on meeting specific criteria. Finally, stopping all motion immediately is not characteristic of the WAIT function, as it is designed to manage waiting in relation to program flow rather than halt operations entirely.
