The devices in the 'Lexium 62' and 'Lexium 62 ILM' product series include integrated functionalities for SS1, STO, SS2, SOS, SDS, SDI, SLS and SMS. With 'PacDrive 3', users of motion control technology can now implement differentiated concepts for safety-related automation up to Cat. 4/PL e in accordance with EN ISO 13849-1 and SIL 3 in accordance with IEC 61508. Compared to the standard drives, they have an extended range of safety-relevant functions: STO (Safe Torque Off), SS1 (Safe Stop 1), SS2 (Safe Stop 2), SOS (Safe Operating Stop), SLS (Safe Limited Speed), SDI positive/negative (Safe Direction, both directions of rotation) and SMS (Safe Maximum Speed). The same range of functions is also available for the integrated servo drives of the 'Lexium 62 ILM' series via an optional module. By relocating the control electronics of a servo drive to the field, concepts for automation without control cabinets are possible. The option module is flange-mounted to the standard electronics of the drives. The safe integrated drives communicate via Sercos. The safety-related communication takes place in parallel to the standard communication on the Sercos Automation Bus.
