Introduction
This manual describes the operational characteristics of the MC1241A
and MC1141A Motion Processors. These devices are members of
PMD's 1st generation motion processor famly, 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 famly of dedicated motion processor chips which
can handle a large variety of systemconfigurations.
Each of these chips utilize a simlar 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 simlar 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 MC1241A and
MC1141A chipsets. For technical details on other members of
PMD's 1st 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 PWMor 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
PWMor DAC-compatible format.
MC1241 series (MC1241A, MC1141A)
- These chipsets provide
internal mcrostepping generation for stepping motors. They are
available in a one or a two-axis version. Two phased signals are
output per axis in either PWMor DAC-compatible format. An
incremental encoder signal can be input to confirmmotor 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.
