Your benefits

Flexible system concepts
can be easily achieved thanks to our system buses: both in central control cabinet installations and in decentralized systems.

Easier to install
as interfaces are avoided or completely integrated.

Simple startup
as the SEW-EURODRIVE system buses are optimally adjusted to the drive electronics and the controller and are preset.

Fast data exchange
ensures smooth processes and accurate status messages and therefore a system that operates economically and smoothly.

Integrated diagnostics concept
as components, network and tools are seamlessly integrated into one another.

Remain flexible

In applications with our control and drive technology, we also recommend SEW-EURODRIVE system bus technologies as an alternative to standardized fieldbus or Industrial Ethernet networks.

This allows you to remain really flexible: SEW-EURODRIVE system buses support central system concepts with control cabinet installations as well as decentralized drive systems, and also combinations of both.

SEW-EURODRIVE system buses are seamlessly integrated into the unit hardware. This reduces the number of bus cables required and it is even possible to have structures without any bus cables.

Save on time and costs: besides the hardware integration, the software-side integration into the components and the startup and diagnostics software all help to achieve a system that operates economically and smoothly.
Contact form Worldwide locations Inverter technology Control technology SNI (Single Line Network Installation)

combines the advantages of reduced installation effort with the technology of Ethernet-based communication in a single innovative drive infrastructure solution:

  • Electrical energy infrastructure used as basis for transferring the Ethernet-based communication signals
  • Ethernet-based access to all individual participants from a central point
  • Significant reduction in installation times as only supply cables need to be connected
  • Maximum expansion of the line topology for up to ten drives on a cable length of 100 m in total.
  • Installation with shielded standard cables in accordance with the SEW-EURODRIVE regulation, no special cables necessary
 SBus (CAN-based SEW-EURODRIVE system bus)

CAN technology, which was developed for use in mobile applications is also used in automation:

  • Consistent use of the multi-master functionality of the CAN for data exchange between drives, on a project-specific basis even completely without additional controllers
  • The SBus also supports applications that require HART real time conditions for communications. Applications such as “Electronic Gear Unit” and “Multi-axis MotionControl” allow the clock-synchronous transfer of setpoints and actual values between the drives themselves or in the network with a controller
  • Cost-efficient networking through the use of standard CAN bus cables, via screw connections in the control cabinet and, alternatively, also with M12 plug connectors standardized for DeviceNet or CANopen in decentralized applications
  • Maximum extension of the line topology to 500 m. The number of drives and peripheral components is limited to 64 but is generally under 20
 SBusPLUS (EtherCAT®)

In networks with our controllers and our drive technology, SBusPLUS provides not only optimal integration but also additional functions for simple and fast startup:

  • EtherCAT® is a HART (real time) capable communication technology, which also proves to be flexible in matters related to installation
  • Star, tree and line topologies, all also with spur lines, can be implemented practically without impacting performance
  • Further information is available from the ETG (EtherCAT Technology Group)
