4.2 NETWORK TOPOLOGY
The AC drive supports EtherCAT bus. It adopts the standard RJ45 network port and standard connector. The Cat
5e shielded twisted pair cable with iron shell injection molding must be used to connect with the Ethernet
master station properly. With relevant communication setting, the communication with the EtherCAT master
station can be realized, thus realizing the networking function of the AC drive.
The topological structures supported by EtherCAT include bus, star, and tree topologies. Various networking
can be realized by using switches correctly.
Bus topology:
Star topology:
NOTE For this type of topology it is necessary to use a special switch such as the Inovance’s GR10-EC-6SW 6-
Port EtherCAT Branch Module.
