CANopen External Communication Cards
The Eaton PowerXL DG1 series drive can be connected
to the CANopen system using a fieldbus board. Through
this board the drive can be controlled, monitored and
programmed from the Host system. The CANopen fieldbus
board can be installed in either slot A or slot B on the
control board of the drive. The devices are connected in
a bus structure. There is a maximum of 127 devices that
can be connected to a single master. The bus termination
should be made on the end of the bus segment.

CANopen cable
To meet the ISO 11898 standard, cables to be used with CANbus lines should have a nominal impedance of 120 ohms, a
line delay of 5 ns/m. Line termination has to be provided through termination resistors of 120 ohms on both ends of the
transmission lines. The length should be related to resistance at 70 mohm/m. There is a terminating resistor bank on all
boards and can be set via the DIP switch setting.
Below are the practical bus length for CANopen networks with less than 64 nodes.
