These drive products feature SIL 3 safe torque off (STO) as standard. Safety Module 1 also adds safe brake control (SBC), which provides a safe 24-V supply for brake operation. The drive periodically checks the internal brake transistor function. Safety Module 3 features safe motion functionality according to IEC 61800-5-2. Advanced motion-based safety functionality is possible in the drive. This improves reaction time in e-stop scenarios and reduces the need for separate protective devices. Module 3 also offers failsafe over EtherCAT (FSoE) functionality by which STO and all other KEB-supported safety functions can be controlled via the bus.
