SEW-Eurodrive Movifit FC/MC drive S12 functional safety option

SEW-Eurodrive now offers an integrated S12 safety option for its decentralised Movifit FC/MC drive units, used for constructing modular and flexible conveyor systems. The two option card versions S12A and S12B support different numbers of safety-related inputs and outputs.

The S12 option offers the additional safety functions STO (safe torque off), SS1a/c (safe stop 1), SLS (safely limited speed) and SDI (safe direction) on top of the standard Movifit functions. The SLS function can be easily applied using the EI7C/(FS) simple motor-integrated encoder.

The safety functions are an integral element of the Movifit modular system. The company’s Movitools MotionStudio engineering software is used to program the S12.

The S12 safety option is a cost-effective, integrated safety solution, and it can be used either independently or as a fieldbus slave with Profisafe via Profibus or Profinet. The inputs can also be set as 1- or 2-channel, and they can read OSSD-capable sensors such as light grids and scanners.

The safety option is useful wherever materials need moving, such as on roller conveyors, rotary tables and electrified monorail systems for light loads. This is particularly relevant for the intralogistics sector.
