12 Safe brake management with SD6 and SE6
Do you design gravity-loaded axes? Then you can depend on the 2-brake
solution from STOBER! Combine the synchronous servo geared motors
with redundant brake with STOBER drive controllers of the SD6 series with
integrated SE6 safety module. This combination offers you safe brake man-
agement and standard-compliant protection for your gravity-loaded axes.
Safe, state-of-the-art brakes
Gravity can cause vertical axes and their loads to fall, posing a danger to people. To prevent this, vertical axes are generally secured by
brakes. However, the braking effect can be seriously impaired by contamination or wear. The state of the brakes must therefore be moni-
tored reliably and their functionality maintained.
Safety with a system
STOBER synchronous servo geared motors can be equipped with an additional ServoStop brake. This brake is integrated directly in the
adapter, located between the gear unit and motor. Together with the brake of the motor, this gives you a 2-brake solution with uniquely
compact dimensions.
In combination with the SD6 drive controller and the SE6 safety module developed in cooperation with Pilz GmbH & Co. KG, planners and
engineers get a system solution for use in safety-relevant applications up to PL e, SIL 3 in accordance with EN ISO 13849-1 and
EN 61800-5-2.
In addition to the basic Safe Torque Off (STO) safety function, SE6 provides other safety functions specified in EN 61800-5-2. In addition to
the safe stop functions Safe Stop 1 (SS1) and Safe Stop 2 (SS2), these also include Safely-Limited Speed (SLS), Safe Brake Control (SBC), Safe
Direction (SDI) and Safely-Limited Increment (SLI). The normative safety functions are supplemented by practical additional functions such
as Safe Brake Test (SBT).
