AC and DC parameters for the CANopen network

Bus cable and termination resistors

The cables, connectors, and termination resistors used in
CANopen networks must meet the requirements specified in
ISO 11898.
The table below lists the standard values for DC parameters for
CANopen networks with less than 64 nodes:
