Field of application

The modular SINAMICS S120 Cabinet Modules drive system is used to coordinate multiple
motors in a multi-axis drive system.
Typical examples include:
● Paper-making machines
● Roller mills
● Hoisting gear
● Test stands
Moreover, high-power single drives (parallel connection) can also be implemented with
Cabinet Modules.

– A standard PROFIBUS interface and various analog and digital interfaces allow them
to be easily integrated into automation solutions.
– Vector control ensures that they fulfill the most exacting requirements regarding the
accuracy and dynamic response of drives.
– Individual modules and power components can be replaced quickly and easily, which
ensures a higher level of plant availability.
– If the drive system includes both motorized and regenerative motors, they can be
coupled by means of a common DC link in such a way that allows mutual energy
exchange to take place. This allows for additional energy savings and the reduction of
line harmonic distortions.
– In certain cases, the supply infeed of the drive line-up can even be designed to supply
less voltage than the total power of the individual Motor Modules operated on the
common DC link would require.
– Simple commissioning thanks to the menu-driven "STARTER" commissioning tool.
– Optional menu-driven AOP30 advanced operator panel with a plain-text display.
– All device modules are easily accessible, which makes them extremely service
friendly.
– The converters are exceptionally quiet and compact thanks to state-of-the-art IGBT
power semiconductors and an innovative cooling concept.
