MC2300 Technical Specifications

Introduction
This manual describes the operational characteristics of the MC2340, MC2320 and MC2310 Motion
Processors from PMD. These devices are members of PMD’s second-generation motion processor
family, which consists of 14 separate products organized into 5 series.
Each of these devices are complete chip-based motion processors. 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 chipset may be re-used with another, even though the type of motor may be
different.
Each chipset consists of two PQFP (Plastic Quad Flat Pack) ICs: a 100-pin Input/Output (I/O)
chip, and a 132-pin Command Processor (CP) chip.
The four different series in the Navigator family are designed for a particular type of motor or
control scheme. Here is a summary description of each series.
Family Summary
MC2100 Series (MC2140, MC2120, MC2110)
– This series outputs motor commands in either
Sign/Magnitude PWM or DAC-compatible format for use with brushed servo motors, or with
brushless servo motors having external commutation.
MC2300 Series (MC2340, MC2320, MC2310) –
This series outputs sinusoidally commutated
motor signals appropriate for driving brushless motors. Depending on the motor type, the output is a
two-phase or three-phase signal in either PWM or DAC-compatible format.
MC2400 Series (MC2440, MC2420, MC2410)
– This series provides microstepping signals for
stepping motors. Two phased signals per axis are generated in either PWM or DAC-compatible
format.
MC2500 Series (MC2540, MC2520, MC2510)
– These chipsets provide high-speed pulse and
direction signals for stepping motor systems.
MC2800 Series (MC2840, MC2820)
– This series outputs sinusoidally or 6-step commutated motor
signals appropriate for driving brushless servo motors as well as PWM or DAC- compatible outputs
for driving brushed servo motors.
