Introduction to the MDrivePlus CANopen DSP-402 Implementation

Introduction

This document describes the Operational Modes and Objects utilized by the MDrivePlus CANopen. The MDrivePlus uses

the CiA DSP402 protocol as described the the CiA document CANopen Device Profile for Drives and Motion Control V2.0B.

CAN Message Format

The MDrivePlus is compliant with CAN 2.0B Active Specification. The Data Packets follow the message format shown in

Figure 1.1. The Figure is for reference only, please refer to the CAN 2.0B Specification.
