Features
–
SEW-EURODRIVE system bus technologies especially designed for control and drive technology
from SEW-EURODRIVE: Can be used in centralized and decentralized system concepts
–
SEW-EURODRIVE system buses are perfectly designed and preset for drive electronics and
controllers
-
Reduced installation work as interfaces are avoided or completely integrated
- Fast data exchange
- Integrated diagnostics concept
Technologies
SNI (Single Line Network Installation)
Combines the advantages of reduced installation work with the technology of Ethernet-based
communication in one innovative drive infrastructure solution
–
Use of the electrical energy infrastructure as basis for the transmission of Ethernet-based
communication signals
–
Ethernet-based access to all individual stations from a central point
–
Significantly reduced installation effort as only supply cables need to be connected
–
Maximum expansion of the line topology for up to 10 drives with a total of 100 m cable length
–
Installation with shielded standard cables according to the SEW-EURODRIVE regulations; no
special cables are necessary
SBus (CAN-based SEW-EURODRIVE system bus)
The CAN technology was developed for mobile applications and is also used in automation
applications
–
Consistent use of the multi-master functionality of the CAN for data exchange between the
drives; in some projects without any additional controller possible
–
The SBus allows for applications that require hard real-time conditions for the communica-
tion. The clock-synchronous transmission of setpoint and actual values between the drives or
within the network with a controller makes for applications such as “Electronic gear unit” and
“multi-axis MotionControl”.
–
Inexpensive networking due to use of standard CAN bus cables, in the control cabinet
with
separable screw connection, in decentralized solutions with the M12 plug connectors
standardized for DeviceNet™ or CANopen
–
Maximum expansion of the line topology up to 500 m. The number of drives and peripheral
components is limited to 64, but is usually less than 20
SBus
PLUS
(EtherCAT
®
)
In addition to the ideal integration, SBus
PLUS
offers additional functions in networks with our
controllers and drive technology that allow for an easy and simple startup
–
EtherCAT
®
is a hard real time-capable communication technology that can be flexibly installed
–
Star, tree and line topologies can be implemented with stub lines nearly without any
performance losses
