Bus termination
Assembly and Installation Notes
• Route the bus cables closely along existing grounding surfaces.
4.7 Bus termination
Bus termination (e.g. with bus terminating resistors) is not necessary. If no slave is con-
nected to an EtherCAT
®
device, it recognizes this immediately.
4.8 Setting the station address
EtherCAT
®
devices from SEW-EURODRIVE do not have an address that can be set on
the unit. The units are detected by their position in the bus structure and are assigned
an address by the EtherCAT
®
master. The addresses can be displayed, for example,
using the DBG60B keypad (parameter P093).
4.9 DFE24B operating displays
There are two LEDs on the DFE24B EtherCAT
®
option card that display the current sta-
tus of the DFE24B option and the EtherCAT
®
system.
INFORMATION
In case of fluctuations in the ground potential, a compensating current may flow via the
bilaterally connected shield that is also connected to the protective earth (PE). Make
sure you supply adequate equipotential bonding in accordance with relevant VDE reg-
ulations in such a case.
