Cam indexing units are designed to perform one output index with a partial rotation of the input shaft. The partial rotation of the cam with the output turret rotating is referred as the index period. Rotation of the input shaft without the output turret rotation is referred as the dwell period. The ratio between the index and dwell periods is usually related to time. Index verses dwell periods can vary but the most common for continuous duty cycles are 1:3 ratio or one part index to 3 parts dwell periods. This is typically used for continuous duty cycles when the index drive runs nonstop and the output turret needs to supply a long time for process work.

Indexing units that are driven by machinery may need to match velocity with other equipment. Custom index periods are available to synchronize motions of the equipment to avoid crashing into the rotating dial. Cycle on demand applications do not require long dwell times because the index drive motor is turned off to supply the dwell period time. If the index period is long, the motor drive torque requirement is less. For this reason, it is typical for Sankyo to use a 3:1 ratio or 270° index period with a 90° dwell period with cycle on demand applications.

Timing sensor packages are used to notify the machine controller to stop the index drive motor when the indexing dial is in the correct position. The timing cam(s) are mounted on the index input shaft to interface with a sensor switch. When the sensor detects the notched edge in the timing cam, a signal is sent to the motor controller device.
