The SINAMICS modular system focuses on complex drive tasks in a broad array of industrial applications. The applications include machine concepts that have a central drive, such as printing and packaging applications. It includes modular machine groups where machine units are broken down into single axes.  The S120 SINAMICS drive works with single-motor drives that deliver high accuracy, stability, and sound running conditions in plant machinery. This unit works with single-motor drives used for transport applications that include raising and lowering abilities. It works with drives that do not have regenerative feedback into the line supply including wire-drawing and extruding. The SINAMICS S120 AC drive is built up by a wide range of motors. There are several motors with which the AC drive is compatible. These motors include rotary, linear, synchronous, and induction.
