Safe. Safer. Safety technology.

The SE6 safety module is the product of a joint development by STOBER and Pilz GmbH & Co. KG – and was designed specifically for the SD6 stand-alone drive controller.

In addition to Safe Torque Off (STO), drive-based safety functions from EN 61800-5-2 are available at the highest safety level – including extensive stop and monitoring functions.

You get the advantage of a very fast worst-case response time, the resulting low safety margins and fast recovery. You also get maximum flexibility in the your choice of motors and encoders.

Together with integrated brake management for up to two brakes, the practical SD6 fulfills German Social Accident Insurance (Deutsche Gesetzliche Unfallversicherung, or DGUV) requirements for gravity-loaded vertical axes.

The SY6 safety module adds the Safe Torque Off (STO) and Safe Stop 1 (SS1) safety functions to the drive controllers of the SC6 and SI6 series.

With this safety concept featuring a drive controller and SY6 safety module, the STO and SS1 safety functions are controlled via EtherCAT (Fail Safe over EtherCAT, FSoE).

The SC6 and SI6 series drive controllers successfully passed the EtherCAT as well as FSoE conformance test. This means the communication interface was tested to ensure the reliability and function of the lower-level communication regardless of the vendor.

The SU6 safety module adds the Safe Torque Off (STO) and Safe Stop 1 (SS1) safety functions, controlled via PROFINET (PROFIsafe), to the drive controllers of the SC6 and SI6 series.

SU6 is a fast and wear-free fully electronic solution. This module also makes regular system tests that interrupt operation as well as planning-intensive function tests and their documentation unnecessary.

The SC6 and SI6 series drive controllers successfully passed the PROFINET as well as PROFIsafe conformance test. The communication interfaces of both controllers have been certified by an independent testing institute as part of their respective type-examinations.

The ST6 and SR6 safety modules add the Safe Torque Off (STO) safety function to the 6th generation of drive controllers with safety technology.
ST6 is designed specifically for the SD6 series, the SR6 for the SC6 and SI6 series.

As fully electronic solutions, ST6 and SR6 operate quickly and are free of wear.

Regular, interruptive system tests are unnecessary. In practical terms, this means increased availability of machines and systems.

As an extremely practical feature, the often very time-consuming planning and documentation of functional tests is completely eliminated.

The SX6 safety module expands the range of functions of the SC6 and SI6 drive controllers with numerous safety functions. It is controlled via EtherCAT® (Fail Safe over EtherCAT, FsoE).

The use of SX6 in SB6 is currently in preparation (expected to be available at the end of 2025).

The SX6 enables the classic stop functions Safe Torque Off (STO), Safe Stop 1 (SS1) and Safe Stop 2 (SS2). A special highlight: With multi-axis controllers, the STO function can be activated individually for each axis.

In addition, Safely Limited Speed (SLS) and Safe Speed Range (SSR) ensure that the projected speed limits are always adhered to. Safe Direction (SDI) monitors the direction of movement, while Safely Limited Increment (SLI) limits the step size and Safe Operating Stop (SOS) ensures safe standstill.
