Introduction
This manual describes the operational characteristics of the MC58000 Series Motion Processors from
PMD. These devices are members of PMD’s third-generation motion processor family.
Each of these devices is a complete chip-based motion processor. 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 processors that can handle a large variety of system configurations.
Each of these chips utilize a similar architecture, consisting of a high-speed computation unit, along
with an ASIC (Application Specific Integrated Circuit). The computation unit contains special on-
board hardware that makes it well suited for the task of motion control.
Along with similar hardware architecture these chips also share most software commands, so that
software written for one series may be re-used with another, even though the type of motor may be
different.
