Which modes are controlled by the key switch?

• A. Auto, Manual, and Pause
• B. Teach, Play, and Remote [Play]
• C. Run, Stop, and Hold
• D. Service, Diagnostics, and Maintenance

Answer: (B)

The key switch on many Motoman robots is designed to select the primary operator modes that govern programming and controlled execution. When you set it to Teach, you can manually jog and record positions to teach the robot new motions. In Play, the robot runs a program that has already been taught, performing automated tasks without ongoing programming. Remote [Play] lifts the same Play capability to a remote interface, allowing a supervisor or external device to initiate and control the program execution safely from outside the pendant. These modes are the ones specifically tied to the key switch for programming and safe operation.

Other groupings don’t align with what the key switch typically governs: Run/Stop/Hold and Auto/Manual/Pause relate to different control schemes or sequencing that aren’t directly selected by the key switch, and Service/Diagnostics/Maintenance refer to maintenance environments accessed through separate procedures.
