Page 52 Chapter 5 CANopen OverviewEL-C 5-1 CANopen Overview CANopen Protocol CANopen is a CAN-based higher layer protocol, and was designed for motion-oriented machine control networks such as handling systems. CANopen 301 (Version 4.02) is standardized as EN50325-4. The CANopen specifications cover the application layer and communication profile (CiA DS301), as well as a framework for programmable devices (CiA DS302), recommendations for cables and connectors (CiA DS303-1) and SI units and prefix representations (CiA DS303-2).
Page 53 Chapter 5 CANopen OverviewEL-C NMT (Network Management Object) The Network Management (NMT) follows a Master/Slave structure for executing NMT service. A network has only one NMT master, and the other nodes are slaves. All CANopen nodes have a present NMT state, and the NMT master can control the state of the slave nodes. The following shows the state diagram of a node: (1) After power is applied, start in the auto-initialization state A: NMT...

Page 56: Wiring For Canopen
Chapter 5 CANopen OverviewEL-C 5-2 Wiring for CANopen CANopen wiring of the EL-C drive does not require a Hub. The connector from the drive adopts the two-way RJ45 with one-in and one-out. You must wire the two farthest ends with 120 Ω terminating resistors as shown in the picture below.
Page 57 There are two control modes for CANopen: the DS402 standard (Pr.09-40=1) is the default, and the Delta’s standard setting (Pr.09-40=0). There are two control modes according to Delta’s standard. One is the old control mode (Pr.09-30=0); this control mode can only control the motor drive under the frequency control.
Page 58 Chapter 5 CANopen OverviewEL-C 5-3-2 DS402 Standard Control Mode 5-3-2-1 Related settings for an AC motor drive (following the DS402 standard) If you want to use the DS402 standard to control the motor drive, follow these steps: Wire the hardware (refer to Section 5-2 Wiring for CANopen). Set the operation source: set Pr.00-21 to 3 for CANopen communication card control.
Page 59 Chapter 5 CANopen OverviewEL-C When the motor drive turns on and finishes the initiation, it remains in Ready to Switch On status. To control the operation of the motor drive, change to Operation Enable status. To do this, set the control word's bit0–bit3 and bit7 of the Index 6040H and pair with Index Status Word (Status Word 0X6041).

Page 64 Chapter 5 CANopen OverviewEL-C 5-3-5 Control DI/DO by CANopen To control the DO of the motor drive through CANopen, follow these steps: Define the DO to be controlled by CANopen. For example, set Pr.02-13–02-16 = 50 to control MO1–MO4. Control the Index mapped by CANopen. To control DO by setting Index 2026-41 = 1, to control MO1 into ON by setting bit 0 of Index 2026- 41 = 1, then MO1 outputs 1.
