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
SN± (SingLe ²ine Network ±nstaLLation)
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
–
Signi²cantly 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-EURODR±VE 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 communication.
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 sep-
arable 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
P²US
(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 ±exibly installed
–
Star, tree and line topologies can be implemented with stub lines nearly without any perfor-
mance losses
