SGDV-OCB01A - CANopen Network Module for Sigma-5

The SGDV-OCB01A is an add-on board, compatible with Sigma-5 series command option attachable type amplifiers SGDV – xxx x E x A. It provides an interface for a CANopen communication network. The CANopen interface enables the user to achieve high-speed distributed control with a high level of reliability.

CANopen is a higher-layer protocol commonly used in the automation industry. The specification of this protocol is maintained and developed by the CiA organization (www.can-cia.org).

The CANopen network module offers a wide range of functions based on the following:

  • CANopen DS-301 specification
  • Drive profiles according to DSP-402, V2.0 support the following modes: Profile Position Mode, Homing Mode, Profile Velocity Mode, Profile Torque Mode, Interpolated position mode
  • Rotary switches for setting node ID – up to 127 nodes
  • Communication rate of up to 1 Mbps
  • Standard 9-pin D-type connector
  • Two indicator LEDs according to CiA303-3

The CANopen network module is conform to:

  • CiA Specifications
  • Safety Standard UL508
  • Material Compliance UL94V-0
  • RoHS Directive 2002/95/EC
  • WEEE Directive 2002/96/EC
  • Low Voltage Directive 73/23/EEC
  • EMC Directive 89/336/EECmodels
