Section 1 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 onl

Device Control The starting and stopping of the drive and several mode specific commands are executed by the state machine. Modes of Operation The operation mode defines the behavior of the drive. The following modes are defined in this profile: Homing Mode This chapter describes the various methods to find a home position (also: reference point, datum, zero point). Profile Position Mode The positioning of the drive is defined in this mode. Speed, position and acceleration can be limited and pr

Trajectory Generator The chosen operation mode and the corresponding parameters (objects) define the input of the Trajectory Generator. The Trajectory Generator supplies the control loop(s) with the demand values. They are generally mode specific. Each Mode may use its own Trajectory Generator. A general description of its functionality is given in Section X, which is related to the Profile Position Mode. Objects and the Object Dictionary In a CANopen network, a device is controlled by writing

Section 2 Accessing The MDrivePlus CANopen Introduction The access from the CAN network to the drive is done through data objects. Process Data Object (PDO) PDOs are messages in an unconfirmed service. They are used for the transfer of real-time data to and from the drive. The transfer is fast, because it is performed with no protocol overhead what means to transport eight application data bytes in one CAN-frame. The PDOs correspond to entries in the Object dictionary. PDO Attributes 1. Two Ty

PDO Mapping The MDrivePlus CANopen allows you to map objects to PDOs to reduce the transfer application data more efficiently. By using the PDO the user can map a PDO to multiple objects (8 Data Bytes max.) The example will show RPDO 1400 mapped to Control Word (6040 ) and Target Position (607A ). h h h RPDO Index Sub-Index Mapped To Index Bytes 1600 00 h h 1600 01 6040 2 h h h 1600 02 607A 4 h h h PDO Mapping Procedure (Consumer PDO) PDO Mapping Example 1: Profile Position Mode – Mapping Cont
