Play it safe with STOBER
For mechanical engineers, safety technology is among the most complex and possibly most unpopular topics.
To fully meet the standard requirements, STOBER offers a portfolio of field-proven safety functions that are perfectly coordinated to its drive controllers and inverters.
The Safe Torque Off (STO) safety function, for example, is already available as standard for 6th generation drive controllers.
And with the SE6 safety module, you get the benefit of a cost-effective solution with maximum safety, a wide range of functions, and more flexibility. And it is so fast and easy!
All safety modules respond quickly and are free of wear.
SE6: Advanced 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.
SY6: STO and SS1 using FSoE
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.
ST6 and SR6: STO
The ST6 and SR6 safety modules add the Safe Torque Off (STO) safety function to the 6th generation of drive controllers.
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.
ASP 5001: Safety technology for the 5th generation
The 5th generation inverters can be optionally equipped with the ASP (AnlaufSPerre) 5001 module, which implements the Safe Torque Off (STO) safety function.
With suitable external wiring, for example, the Safe Stop 1 (SS1) safety function or a Category 1 stop can also be implemented in compliance with DIN. Here, STO acts as the safe fallback level.
