Your benefits

Functionally safe drive technology
Machines and systems run safely and without interference.

Protect operating personnel
Functional safety of the systems prevents accidents at work and thus protects employees.

Increase productivity
Safely supported production thanks to the many products and safety services in our portfolio.

Reduce costs
Contactor protection of the systems with MOVISAFE® reduces the safety zones. This saves costs and increases efficiency.

Many applications, different industries
Already in use in conveyor lines, corner transfer units, storage/retrieval systems, vertical drives, pumps and centrifuges.

Safety with every movement

Inverters and decentralised inverters from the MOVI-C® modular automation system feature the integrated Safe Torque Off (STO) safety function in accordance with IEC 61800-5-2 as standard in the basic unit.

For all applications that require more than the safe stop function (STO), simply expand the functional safety of the inverters from SEW-EURODRIVE with plug-in expansion cards. These MOVISAFE® CS..A safety options adapt the scope of the safety functions of these devices quickly and easily, customised to the requirements of the application.

Switch-off, safe disconnection/stop, movement or positioning (relative/absolute) - simply select the safety function required for the application and safety for man and machine is guaranteed.

The safety options are available for a wide range of application concepts:

  • Motion functions with safe encoder: MOVISAFE®, type CSS.A, CSL..A
  • Motion and position functions with safe encoder systems or a safe encoder section: MOVISAFE®, type CSA31A

MOVISAFE® CS..A expansion cards - flexible selection of safety option

With the MOVISAFE® CS..A safety options, the MOVI-C® modular automation system is expanded to include the common PROFIsafe, Safety over EtherCAT® and CIP SafetyTM safety protocols for direct safe communication between your devices and a safety controller.

Do you want to use a MOVI-C® CONTROLLER and MOVI-C® FIELD CONTROLLER to control the axis modules from SEW-EURODRIVE? No problem:

All controllers route the PROFIsafe data to the safety options, allowing direct communication between your safety controller and the axis modules and MOVISAFE® CS..A safety options, thus avoiding multiple safety programmes and reducing complexity in the system.

Or do you want to dispense with the superimposed safety controller?

Then Safety over EtherCAT® is the right choice - here MOVI-C® CONTROLLERs are linked to the axis modules via a Safety Control Unit (SCU safety controller) - all from a single source, with components from SEW-EURODRIVE.

Functional safety makes a significant contribution to increasing the productivity of machines and systems. Choose the modular safety technology that suits your application and customise it to your individual requirements.

Our objective is to fulfil all functional safety requirements for machines and applications that require a large number of safe I/Os. For this purpose, MOVI-PLC® I/O modules include two Safety over EtherCAT® I/O modules, each with four safe inputs and outputs. Simply integrate these into your application solution with a "SCU" safety controller. The modules integrate external, functionally safe field units into the machine and system structure and process their signals. This means maximum flexibility in the design and architecture of applications.

The modules

  • Bus coupler for EtherCAT® OCE12C
  • Digital input module with functional safety OFI41C
  • Digital output module with functional safety OFO41C

The functions

  • Safety integrity level 3 according to standard IEC 61508
  • PL e / Cat. 4 according to standard EN ISO 13849-1
  • Safety protocol: Safety over EtherCAT®

Control technology

MOVIDRIVE® and MOVITRAC® are the inverters in control cabinet technology. The stop and idle state safety functions are integrated in these basic units. If these are not sufficient for the requirements of the application, the scalable MOVISAFE® CS..A safety options extend the functional safety of the inverters. These are plug-in expansion cards that can be retrofitted at any time.

  • Configurable safety functions such as SBC, SDI or SLS (available depending on the functional safety option)
  • With STO via PROFIsafe, communication parameters can be set directly via the TIA portal using a free SEW plug-in

Functional safety can also be flexibly designed in decentralised installations with components from SEW-EURODRIVE - even with demanding requirements for the safety of people and machines. The STO (SafeTorque Off, in accordance with standard IEC 61800-5-2) safety function is integrated as standard in decentralised inverters and drive units up to PL e/ SIL 3.
