CANopen DATA TRANSFER SETTINGS
The CANopen networking concept is based on the international standard CAN. CANopen is
defined as a uniform application layer by the DS301 specifications of the CiA (CAN in Automation).
CANopen CABLE ARRANGEMENT
The CANopen interface uses a D-SUB 9-pin plug connector. The plug is assigned with the CAN_H,
CAN_L and, CAN_GND connections. CAN_H and CAN_L are the two conductors of the CAN bus.
CAN_GND is the common reference potential.
NOTE:
 The resistance of the cable value must be 70 mW/m (1.77 mW / in.) or less.
 To minimize signal reflections from the end of the cable, a 120 W. (5%, 1/4 W maximum) line
termination must be placed at both ends of the bus.
CANopen Communication Cable and Connectors
NOTE: CANopen communication cables and cable connectors are not supplied with the CANopen
Master Unit. The user must prepare the cables.
