What is the primary purpose of program timers in FANUC systems?

The primary purpose of program timers in FANUC systems is to delay program execution. Timers are integral in robot programming as they allow for the introduction of specific time delays within a program's operation. This capability can be vital in situations requiring synchronization with other devices, accommodating for mechanical operations or ensuring that the robot does not proceed too quickly, thus allowing it to interact with parts or other machinery safely.

By incorporating timers, programmers can manage the flow of the robotic operations more effectively, ensuring that tasks occur in a defined sequence and that the robot maintains proper timing with external processes. Using timers helps to control various elements within the robot's tasks, enhancing overall operational efficiency and safety.
