NETWORK INSTALLATION

Following are recommendations related to equipment installation in an EtherCAT network. Details on the characteristics
of the components used for installation can be obtained along the ETG.
4.1

CABLE

Recommended characteristics for the cable:
Standard Ethernet cable, 100Base-TX (FastEthernet), CAT 5e.
Shielded cable.
Maximum length between devices: 100m.
4.2

NETWORK TOPOLOGY

To connect CFW11 frequency inverter in an EtherCAT network, it is necessary to observe the Ethernet connector on
the device used for connection.
The network always start by the EtherCAT master.
The X1 connector (IN) should always be connected to the network segment leading to the EtherCAT master.
The X2 connector (OUT) should always be connected to the network segment leading to other EtherCAT slaves.
When connected in a ring topology for redundancy, the X2 connector (OUT) of the last slave can be connected
to the second port of the EtherCAT master, otherwise it should be leave disconnected.
4.3

RECOMMENDATIONS FOR GROUNDING CONNECTION AND CABLE ROUTING

The correct connection with the ground decreases problems caused by interference in an industrial environment. The
following are some recommendations about grounding and cable routing:
Always use shielded twisted pair Ethernet cables and connectors with metallic casing.
