        Simply safe - twice the efficiency!

        SINAMICS Safety Integrated

        The SINAMICS drive family offers converters for each power and performance level. Not only this, but SINAMICS converters have the safety functions seamlessly integrated in the standard portfolio. The drives are simply linked to SIMATIC, SINUMERIK and SIMOTION controls, and through communication via PROFIsafe, are perfectly harmonized with these. This offers you shorter commissioning times and a higher cost effectiveness thanks to efficient engineering and lower wiring costs.

        Safety functions

        Integrated safety functions

        Failsafe drives are characterized by their integrated safety functions, which they provide to the user as possible responses to safety-related events. The Safety Integrated Functions available in Siemens drives are subsequently described. The functional safety of all the functions satisfies the requirements defined in Part 5-2 of the international standard IEC 61800 for variable-speed drive systems. The SBT and SP functions go beyond the scope laid down in IEC 61800-5-2.  

        Functions to safely stop the drive

        Safe Torque Off (STO)

        STO safety sets the drive into a torque-free condition: an undesirable restart is safely prevented. A fast restart is possible after STO has been deselected as the DC link remains charged.

        Safe Stop 1 (SS1)

        The drive is quickly and safely stopped and monitored – especially for high moments of inertia.

        Safe Stop 2 (SS2)

        The drive is quickly and safely stopped and then SOS is activated.

        Safe Operating Stop (SOS)

        The position is safely held and monitored at standstill for each drive control.

        Functions for safe brake management

        Safe Brake Control (SBC)

        A holding brake is controlled and monitored in a safety-related fashion, especially for vertical axes; is always activated in parallel with STO.

        Safe Brake Test (SBT)

        Up to two brakes per axis can be cyclically tested using the SBT diagnostic function.

        Functions for safely monitoring drive motion

        Safely-Limited Speed (SLS)


        The speed/velocity value of the drive is monitored in safety-related fashion, and a configurable stop response is initiated when the limit value is violated.


        Safe Speed Monitor (SSM)

        A safety-related velocity/speed monitoring function supplies a safety-rated signal as long as the drive operates below a specified speed/feed velocity.

        Safe Direction (SDI)

        The direction of rotation is monitored in a safety-related fashion so that the drive can only move in the permissible direction; a configurable fault response is initiated if the drive moves in the incorrect direction.

        Safely-Limited Acceleration (SLA)

        It is safely monitored that the drive does not exceed a preset acceleration limit value.

        Functions for safely monitoring the position of a drive

        Safely-Limited Position (SLP)

        Protection zones are monitored in a safety-related fashion using defined traversing ranges.

        Safe Position (SP)

        The SP function transfers the safe position actual values of the drive to the F control for further processing via PROFIsafe.

        Safe Cam (SCA)

        Safe cams supply a safety-related signal if the drive is located within a configured position range.

        Our customers are convinced

        Significant advantages are obtained for machine OEMs and users to the same extent by integrating safety functions in the drive. The costs to realize a safe machine are drastically reduced – and the reliability of the solution has been clearly proven in many applications around the globe.

        WEILER Werkzeugmaschinen GmbH

        Depending on the specific machine, by using Safety Integrated, we have reduced our wiring costs by between 50 and 70 % - i. e. time and material; in addition, a significant amount of space has been freed up in the control cabinet.

        Armin Daum , Head of Electrical Design, WEILER Werkzeugmaschinen GmbH

        MiniTec GmbH & Co. KG

        We started with the hardware planning, and simply added the safety functions using a memory card. We have been able to build our systems as usual but now the systems can be commissioned 30 % faster.
