Introduction

This manual describes the operational characteristics of the MC1401A,

MC1201A, MC1101A, MC1401A-P, MC1201A-P, and MC1101A-P

Motion Processors. These devices are members of PMD's 1st

generation motion processor family, which consists of 16 separate

products organized into four groups.

Each of these devices are complete chip-based motion controllers.

They provide trajectory generation and related motion control functions.

Depending on the type of motor controlled they provide servo loop

closure, on-board commutation for brushless motors, and high speed

pulse and direction outputs. Together these products provide a

software-compatible family of dedicated motion processor chips which

can handle a large variety of system configurations.

Each of these chips utilize a similar architecture, consisting of a high-

speed DSP (Digital Signal Processor) computation unit , along with an

ASIC (Application Specific Integrated Circuit). The computation unit

contains special on-board hardware such as a multiply instruction that

makes it well suited for the task of motion control.

Along with a similar hardware architecture these chips also share most

software commands, so that software written for one chipset may be re-

used with another, even though the type of motor may be different.

This manual describes the operation of the MC1401A, MC1201A,

MC1101A, MC1401A-P, MC1201A-P, and MC1101A-P chipsets. For

technical details on other members of PMD's first generation

motion processors see the corresponding product manual.

Family Summary

MC1401 series (MC1401A, MC1201A, MC1101A, MC1401A-P,

MC1201A-P, MC1101A-P) - These chipsets take in incremental

encoder signals (standard version) or parallel word encoder signals

(-P version) and output a motor command in either PWM or DAC-

compatible format. These chipsets come in 1, 2 or 4 axis versions

and can be used with DC brushed motors, or brushless motors using

external commutation.

MC1231 series (MC1231A, MC1131A) - These chipsets take in

incremental quadrature encoder signals and output sinusoidally

commutated motor signals appropriate for driving brushless motors.

They are available in one or two axis versions. Depending on the

motor type they output two or three phased signals per axis in either

PWM or DAC-compatible format.

MC1241 series (MC1241A, MC1141A) - These chipsets provide

internal microstepping generation for stepping motors. They are

available in a one or a two-axis version. Two phased signals are

output per axis in either PWM or DAC-compatible format. An

incremental encoder signal can be input to confirm motor position.

MC1451 series (MC1451A, MC1251A, MC1151A, MC1451A-E,

MC1251A-E, MC1151A-E) - These chipsets provide very high speed

pulse and direction signal output appropriate for driving step motor-

based systems. They are available in a one, two, or four-axis version

and are also available with quadrature encoder input.

Each of these chipsets has an associated Chipset Developer's

Kit available for it. For more information contact your PMD

representative.
