2.1 General Description

The ORMEC Generation III Model 20 & 40 Motion Controllers are industrially

hardened computers designed especially for high performance control of

automation using servomotors. They are fully compatible with ORMEC’s lines

of brushless servomotors and drives.

At the heart of both the Model 20 and 40 is a 12-Mhz Intel 80C186 main

processor. It is interfaced through dual-ported "shared memory" to DSP Axis

Modules which are controlled by Texas Instruments Digital Signal Processors

operating at 40 Mhz. This powerful architecture provides the foundation for

general purpose motion control programmed in ORMEC’s industrialized

superset of Microsoft BASIC called MotionBASIC®

. The combination of a main

processor from Intel’s premier family of microprocessors and Digital Signal

Processors for axis control provides speed and performance while maintaining

the ease-of-use associated with interpreted BASIC.

The Model 20 provides two PC-AT style I/O slots and is designed for systems

which have between 11/2 and 4 axes of motion control. For 11/2 to 2 axis

systems, the second slot can be used for various communications options such

as a video controller, a PLC network interface or additional serial interfaces.

The Model 20 can provide 21/2 to 4 axes of control for many applications.

Examples of this are systems interfaced via ModbusTM or an MMI-840 Industrial

Terminal, which provides an 8-line by 40-character display.

The Model 40 provides four PC-AT style I/O slots and is designed for systems

which have between 21/2 and 8 axes of motion control.

Generation III motion controllers provide electronic gearing for a virtually

unlimited number of servomotors using ORMEC’s proprietary MotionDATATM

communications capability. This feature can be used to either closely
