SECTION 1 − DESCRIPTION
The Industrial Indexing Systems MSC-250 is a microprocessor-based, position-loop servo
controller. It is a dual 32-bit technology, 2½-axis, closed-loop servo controller that works
with separate servo drives, motors, and encoder feedback devices to accurately fix the
position of the motor shaft.
1.1 INDEXING DRIVE SYSTEM OVERVIEW
An indexing drive system (or indexing system) may be used in a variety of applications
where accurate movement or positioning is required. A basic single-axis system consists
of eight main components as illustrated in Figure 1.1.
1. Input Device: The input device provides data to the controller. It is the
interface between the operator (or system computer or
programmable logic controller) and the indexing system. In
a given system, there may actually be several input devices.
2. Controller: The controller receives data from the input device and issues
commands to the drive. It also accepts information from the
feedback device. The programming and settings of the
controller determine what types of commands are issued to
the drive in response to the data inputs and feedback.
