General description
A modular cabinet unit solution for high performance applications in industrial mechanical engineering and plant construction is available together with the SINAMICS S120 cabinet modules. The cabinet modules are particularly suited to applications where several drives must work together coordinated. The drive system is thereby normally made up of several motor modules which are connected to the common DC link.
The Motor Modules are in turn powered by a central Line Module.
This kind of configuration allows an interchange of energy between the individual drives, as well as offering a compact and cost-effective design. By this, the power supply is relieved. It is often possible to use Line Modules with a lower rated power than the total power of the connected Motor Modules. This in turn reduces space and expenditure. The SINAMICS S120 cabinet modules also allow to build up single motor drives with greater power outputs. E.g. a 4.5 MW drive with 24-pulse-input can be realized by connecting several Line and Motor Modules.
Technical data overview
The SINAMICS S120 cabinet modules system can be supplied for line voltages between 3 AC 380 V - 3 AC 690 V. The cabinet units offer protection ranging from IP20 to IP54.

Customer benefits
The SINAMICS S120 Cabinet Modules system comprises several individual modules that are perfectly harmonized with one another. Standardized interfaces for the power and communication connections mean that the individual cabinet modules can be combined as required. This allows the user to configure the optimal drive for his application. Not only this, but an extensive range of options allows plant-specific requirements to be very flexibly fulfilled. An extremely compact design and the possibility of pre-configuring the drive system in the plant saves space and minimizes the time and costs associated with installation and commissioning on-site.
Of course, it goes without saying that the cabinet modules also offer the advantages of the SINAMICS S120 Drive System:
-
A higher degree of flexibility is achieved by separating the control module and power section.
-
Up to 4 vector drives can be connected to one control module. In addition to a safe and cost-saving design, it also allows information to be directly exchanged between the individual drives - therefore relieving the higher-level fieldbus.
-
DRIVE-CLiQ, the new interface inside the drive, allows fast and reliable communications between the essential SINAMICS S120 drive components including motors and encoders.
-
The PROFIBUS-DP interface integrated as standard allows the SINAMICS S120 Cabinet Modules to be connected to higher-level automation systems such as SIMATIC or SIMOTION.
-
The standard and integrated SIZER and STARTER tools provide valuable support when engineering the drive, commissioning it and troubleshooting (diagnostics).
-
Safety Integrated functions STO and SS1 similar to S120 chassis units.
Typical applications
The modular drive system SINAMICS S120 cabinet modules are particularly suitable for drive tasks where several motors work together. Some typical examples of this are:
-
Moving: Belt conveyors, cranes, ship's drives, test stands, cross cutters, roll changers, roller feeds
-
Processing: Winders / unwinders, leadind / following drives, calenders, mechanical presses, rolling mill drives
Additional application areas include onboard power supplies for ships using a shaft-mounted generator system (based on SINAMICS S120 CM Application Shaft Generator Drive) and standalone grid supplies.
