SEW-Eurodrive is supplementing the certified (SIL 3, PL e) safety modules of the Movisafe UCS.B series with the UCS50B and UCS51B multi-axis logic modules for up to twelve axes. The modules have integrated logic for linking inputs and outputs, and a total of up to 150 digital inputs/outputs can be implemented via additional modules. Safety functions in accordance with IEC 61800-5-2 are supported so that, for example, working in hazardous areas up to the highest safety requirement in accordance with EN ISO 13849-1 Performance Level e (PL e) can be implemented. Continuous, safe speed monitoring and monitoring of the movement function and position ranges of axes significantly reduce reaction times in an emergency. In addition, many mechanical safety devices can be dispensed with. The safety modules communicate optionally via Profisafe with a safety PLC, which switches off the inverter in a safety-oriented manner in the event of a fault. In this case, the drive is stopped during its movement by means of a parameterizable quick stop and the safe torque off (STO) is activated after a delay time.
