Functionally safe drive technology
Machines and systems run safely and without malfunctions.
Protect operating personnel
Functional safety of the systems prevents accidents at work and thus protects employees.
Increase productivity
Safely supported production through many products and safety services in our portfolio.
Reduce costs
Protecting 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 and retrieval machines, hoists, pumps and centrifuges.
The Safe Torque Off (STO) safety function to IEC 61800-5-2 is integrated as standard in the basic unit of inverters and decentralized drive units from the MOVI-C® modular automation system.
For all applications that require more than this safe stop function (STO), you can simply enhance the functional safety of SEW-EURODRIVE inverters using plug-in expansion cards. These MOVISAFE® CS..A safety options make it quick and easy to tailor the scope of these units' safety functions to the application's requirements.
From shutdown to safe standstill/stop, motion, or positioning (relative/absolute) – simply select the safety function you need for your application to instantly ensure the safety of your staff and machinery.
Safety options are available for all kinds of application concepts:
The MOVISAFE® CS..A safety options add the standard safety protocols PROFIsafe, Safety over EtherCAT®, and CIP SafetyTM to the MOVI-C® modular automation system for direct, safe communication between your units and a safety controller.
Are you intending to use a MOVI-C® CONTROLLER and a MOVI-C® FIELD CONTROLLER to control SEW-EURODRIVE axis modules? Not a problem!
All MOVI-C® CONTROLLERS route the PROFIsafe data to the safety options, thereby enabling your safety controller to communicate directly with the axis modules and the MOVISAFE® CS..A safety options. This removes the need for multiple safety programs and reduces system complexity.
Or are you not using a higher-level safety controller?
In this case, Safety over EtherCAT® is the right choice, with MOVI-C® CONTROLLERS linked to the axis modules via a Safety Control Unit (SCU) – all from a single source with components from SEW-EURODRIVE.
Functional safety plays a key role in boosting the productivity of machinery and equipment. Select and customize the modular safety technology to suit your particular application.
Our aim is to fulfil all functional safety requirements for machines and applications that require a large number of safe I/Os. The 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 devices into the machine and system structure and process their signals. This means maximum flexibility in the design and architecture of applications.

MOVIDRIVE® and MOVITRAC® are the inverters in control cabinet technology. The stop and standstill 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.

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 safety function (SafeTorque Off, in accordance with the IEC 61800-5-2 standard) is integrated as standard in decentralised inverters and drive units up to PL e/ SIL 3.
