6.4 CANopen bus networking
6.4.1 Network topology
When the rectifier unit is located at the beginning or end of the system, the CANopen bus network wiring is as shown as
in Figure 6-2. The PLC or another master device connects to the CAN bus terminals of the rectifier unit, and CANopen
bus connection between the rectifier and inverter units are implemented through RJ45. It is recommended to use the
shielded twisted pair cable with the shield layer to connect the master device and rectifier unit, with the shield layer
connected to CGND. Use the network cable as shipped with the product to connect units, and use
120Ω termination
matching resistors at both ends of the bus to prevent signal reflection.

When the rectifier unit is located at the middle of the CANopen bus, the CANopen bus network wiring is as shown as in
Figure 6-3. The CANopen bus connection between the rectifier and inverter units are implemented through RJ45, and
the PLC or another master device is connected to the RJ45B port of the beginning or end unit.
