The Industrial Indexing Systems Motion Control System MSC-250 is a microprocessor

based, position-loop controller. It is a dual 32-bit technology, 2½-axis, closed-loop

controller that works with separate servo drives, motors, and encoder feedback devices to

accurately fix the position of the motor shafts.

The MSC-250 controller is part of the MSC family of controllers and peripheral equipment

produced by Industrial Indexing Systems. It uses the same Macroprogram control

language already familiar to users of the MSC-850 family of controllers and is fully

compatible with this family of controllers.

This manual describes proper installation, operation, and troubleshooting procedures for

the MSC-250 controller. The manual assumes no prior knowledge of Industrial Indexing

System equipment. It does assume knowledge of proper mechanical, electrical, and

electronic maintenance and safety procedures. If the equipment is used in a manner not

specified in this manual, the protection provided by the equipment may be impaired.

Information in this manual is subject to change without prior notification.

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.
