Is it true that a macro with a motion instruction can be assigned to the USER 1 button on R-J3iB and earlier controllers?

The statement is true because FANUC's R-J3iB and earlier controllers allow for macros that include motion instructions to be assigned to the USER 1 button. This feature is particularly useful for operators who may want to quickly execute specific sequences of movements or operations without directly inputting commands each time. By using the USER 1 button, users gain access to predefined actions that can enhance efficiency and streamline workflows on the controller.

The capability of assigning a macro with motion instructions gives users a flexible way to program complex tasks that can be executed at the push of a button, fulfilling the operational needs in various applications. Being able to harness this feature significantly optimizes the usability of the robotic systems, especially in environments where quick adjustments and frequent repetitions of tasks are necessary.
