A typical stepper motor indexing table will have an input from the stopper motor __________, indicating a part is present.

A typical stepper motor indexing table will have an input from the stopper motor __________, indicating a part is present.

• A. Run
• B. Ready
• C. Stop
• D. Start

Answer: (B)

In automated indexing systems, feedback from the stopper mechanism tells the controller that a part is properly positioned and the station is ready to move on. When the stopper motor has placed the part and a sensor confirms its presence, the input is labeled as Ready, signaling that the table can safely index to the next position. This is different from Run (which describes active motion), Start (which begins a cycle), or Stop (which halts motion), none of which specifically convey that a part is in place. So the Ready input best captures the idea of “part present and ready to proceed.”
