SEW-Eurodrive S12 safety option for Movifit decentralised drive inverter

SEW-Eurodrive has developed the integrated S12 safety option for its decentralised Movifit FC/MC drive units, used for constructing modular and flexible conveyor systems. The safety technology is suitable for most applications - from control cabinet technology with integrated or independent axis monitors to decentralised technology.

The safety 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 option 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 (output signal switching device)-capable sensors such as light grids and scanners.

The safety option is suitable wherever materials need moving, for example on roller conveyors, rotary tables or electrified monorail systems for light loads.
