EtherCAT electrical connection
Figure 9.2:
EtherCAT - electrical connection
Notice!
For contacting
BUS IN
and
BUS OUT
, we recommend our ready-made EtherCAT cable (see
chapter 11.3.5 "Accessory ready-made cables for EtherCAT").
To establish an EtherCAT network, the AMS 338
i
provides a receiving bus labeled BUS IN
on the device, and a forwarding bus labeled BUS OUT. The AMS 338
i
can be connected to
BUS OUT or to BUS IN using a stub cable.
For the connection of two AMS 338
i
, the "KB ET - … - SSA" ready-made cables are pre-
ferred, see table 11.3.5 "Accessory ready-made cables for EtherCAT" on page 87.
If you use user-configurable cables, note the following:
Notice!
The entire connection cable must be shielded. The shielding connection must be at the same
potential on both ends of the data line. This prevents potential compensating currents over
the shield and possible interference coupling by compensating currents. The signal lines
must be stranded in pairs.
Use CAT 5 cable for the connection.
