|Ideal Displacement and Velocity Diagram of a rotary indexer|
The input shaft is normally connected to a geared drive (motor) that rotates at a constant speed. The construction inside the indexer (roller gear, cam, conjugate plate cams, etc.) makes the output shaft rotates and stops as shown in the earlier displacement diagram. However, in some applications, it may require longer dwell time for other machine units to do their jobs. For this case, the input shaft (motor) will rotate and stop and wait to extend the dwell time until other machine units have completed their processes then it rotates again. This is also called "cycle-on-demand" application.
