SINAMICS S120 Blocksize

SINAMICS S120 offers high-performance individual AC/AC drives in the Blocksize and Chassis formats as well as coordinated DC/AC drives for multi-axis applications in Booksize, Compact, Chassis, and Cabinet Modules.  The different SINAMICS S120 versions can be combined as required through the DRIVE-CLiQ interface. For instance, Line Modules in the Chassis format can be combined with Motor Modules in the Booksize format to address multi-axis applications with a high total power rating.

Key Attributes

Functions for Increased Efficiency

SINAMICS S120 booksize

• Basis functions: Speed and torque control, positioning functions

• Intelligent starting functions for automatic restart after a power interruption

• BICO technology with interconnection to drive-related I/Os

• Graphic configuring with free blocks using DCC to adapt the drive system in a user-friendly fashion to the machine environment

• Integrated safety functions to cost effectively implement safety concepts

• Controlled infeed / regenerative feedback to avoid undesirable harmonics fed back into the line supply, regenerative feedback when braking and for an increased degree of ruggedness with respect to line supply fluctuations

Motor Compatibility

Whether synchronous or induction, SINAMICS S120 can operate all A/C motor types including linear and torque motors. Siemens 1FK7 and 1FT7 synchronous servomotors as well as the smooth-running 1PH8 induction motor automatically configure with SINAMICS S120 through a digital Drive CLiQ interface with electronic-type plates. When a motor with the DRIVE CLiQ interface is used, encoder feedback and motor parameterization is handled effortlessly in a plug-and-play fashion

Cooling Concepts

SINAMICS S120 Chassis drive units are available both in air-cooled as well as liquid-cooled versions. The liquid-cooled version is ideal for dusty, salt-laden or aggressive ambient air and represents a cost-saving alternative with low operating costs. It allows hermetically sealed cabinet solutions to be implemented with a footprint that is up to 60% smaller.

The Booksize units are either available with internal/external air cooling or with liquid cooling. Drive units with coldplate cooling allow heat to be dissipated through the rear of the units to the mounting surface.

Digital DRIVE-CLiQ interface: For Lower Wiring Costs

Seamless component communications are a prerequisite for a modular, state-of-the art drive system architecture. As the standard digital interface between all of the SINAMICS S120 drive components, the simple, plug-in DRIVE-CLiQ cable reduces the time required.
