INDUSTRIAL INDEXING SYSTEMS, INC. MOTION CONTROL SYSTEM, MSC-250
IB-11B012 USER'S GUIDE
7.
Load:
The load is the object of the motion. It absorbs the work energy of the motor.
8.
Feedback Device:
The feedback device (always a shaft encoder or equivalent A×B×M signal device with the MSC-250 servo controller) monitors the position of the motor shaft and sends this information to the controller. (Refer to Section 1.2.1.1 for additional details on the feedback device.)
The objective of the indexing system is to accurately control the position and speed of rotation of a motor shaft at any given time. This control may be used to move the load a specific distance (index) or to a specific location (position). It also may be used to move the load in a pattern duplicating the motion that would be produced by the action of mechanical cam, remembering that motion can occur in both clockwise and counterclockwise directions.
