         SINAMICS G120 chassis units

The SINAMICS S120 drive system is the system kit for industrial, high-performance applications in the fields of mechanical and system engineering. Numerous harmonized sizes, components and functions are available to design optimal solutions. SINAMICS S120 provides powerful single drives and coordinated drives (multiple-axis applications) supporting vector or servo functions. It covers the 1.6 to 1200 kW performance range with 380-480 V and 500-690 V (50/60 Hz) supply voltages.

The SINAMICS S120 drive system is obtainable in the following formats - Booksize (1.6 to 107 kW), Chassis (75 to 1200 kW) and Cabinet Modules (1.6 to 1200 kW). Higher power ratings up to 4500 kW are implemented using a parallel circuit configuration.

SINAMICS S120, Booksize format are available with 3 different cooling types.
With the "internal air cooling" version, the power loss is dissipated to the inside of the cabinet through self-cooling and forced cooling.

The "external air cooling" version is a version where the SINAMICS S120 heatsink extends outside the cabinet. This allows the power loss to be dissipated to an external cooling circuit.

The "Cold-Plate cooling" is the third version. These particular units can be mounted on external heatsinks that, for instance, can be liquid cooled.

Up until now, the SINAMICS S120 Chassis format was only available in the version "internal air cooling". This series of units has now been expanded by a liquid-cooled version. Contrary to the Cold-Plate cooling, in this case, direct liquid cooling is used. This means that the power components are mounted on a heatsink through which cooling liquid flows.

Cabinet modules are a modular cabinet system for multi-motor drives. The cabinet modules provide a compact and ready-to-use drive solution for use particularly in machines and plants in the paper machinery sector, rolling mills, test bays and hoisting gear. Thanks to standardized interfaces, the individual cabinet modules can be quickly combined with each other and installed.
SINAMICS S120 provides optimal solutions for productivity and flexibility:    
        Perfect basis for modular system and machine concepts through innovative system architecture and digital communication options
        Faster engineering and commissioning via the SIZER and STARTER tools as well as simple cabling with DRIVE-CLiQ
        Efficient and consistent solutions via Totally Integrated Automation (TIA), consistency from SINAMICS through to the automation level

SINAMICS S120 Chassis units - System architecture

SINAMICS S120 separates intelligence and performance to allow the design of future-proof, modular solutions. A central control unit provides central drive control and implements the technological links. As all information required is stored in a central control unit, time-consuming transmission via a field bus has become superfluous. Through its axis grouping, each control unit makes available e.g. specifications regarding the speed and position for several power sections (motor modules).

Via its integrated PROFIBUS-DP interface, SINAMICS S120 can be connected to higher-level automation systems such as SIMATIC or SIMOTION. SIMOTION D in particular supports the implementation of fully drive-integrated motion control solutions.

The system architecture provides major benefits for the development of innovative machine concepts:

        flexible development of drive variants for all industry sectors, tasks and markets
through the scalability of the modular system and the combination of components via DRIVE-CLiQ
        utmost investment security

DRIVE-CLiQ, the uniform digital interface between the most important SINAMICS S120 drive components (incl. motors and encoders) reduces the number of different part types required.

Electronic rating plates in the components allow the automatic detection of all drive components via DRIVE-CLiQ cables. Manual data input upon commissioning or replacement is no longer necessary.
