Introduction

This manual describes the operational characteristics of the MC3310 Motion Processor from PMD.
This device is a member of the MC3000 family of single-chip, single-axis motion processors.

MC3310 Technical Specifications

10

Each device of the MC3000 family is a complete chip-based motion processor providing trajectory
generation and related motion control functions for one axis including servo loop closure or on­board commutation where appropriate. This family of products provides a software-compatible
selection of dedicated motion processors that can handle a large variety of system configurations.

The chip architecture not only makes it ideal for the task of motion control, it allows for similarities
in software commands, so software written for one motor type can be re-used if the motor type is
changed.

Pilot Family Summary

MC3110 – This single-chip, single-axis motion processor 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.

MC3310 – This single-chip, single-axis motion processor outputs sinusoidally commutated motor
signals appropriate for driving brushless motors. Depending on the motor type, the output is a two­phase or three-phase signal in either PWM or DAC-compatible format.

MC3410 – This single-chip, single-axis motion processor outputs microstepping signals for stepping
motors. Two phased signals per axis are generated in either PWM or DAC-compatible format.

MC3510 – This single-chip, single-axis motion processor outputs pulse and direction signals for
stepping motor systems.

The shaded area shows the CPLD/FPGA that must be provided by the designer if parallel
communication is required. A description and the necessary logic (in the form of schematics) of this
device are detailed in section 6 of this manual. The CP chip contains the profile generator, which
calculates velocity, acceleration, and position values for a trajectory; and the digital servo filter, which
stabilizes the motor output signal.

MC3310 Technical Specifications

15

The filter produces one of two types of output:

• a Pulse-Width Modulated (PWM) signal output; or

• a DAC-compatible value routed via the data bus to the appropriate D/A converter.

Axis position information returns to the motion processor in the form of encoder feedback using
either the incremental encoder input signals, or via the bus as parallel word input.

2.5 Peripheral device address mapping

Device addresses on the CP chip’s data bus are memory-mapped to the following locations:

Address Device Description

0200h Serial port data Contains the configuration data (transmission rate,

parity, stop bits, etc) for the asynchronous serial port

0800h Parallel-word encoder Base address for parallel-word feedback devices

1000h User-defined Base address for user-defined I/O devices

2000h RAM page pointer Page pointer to external memory

4000h Motor-output DACs Base address for motor-output D/A converters

8000h Parallel interface Base address for parallel interface communication
