产品描述
SINAMICS S120 Cabinet Modules‑2 are the components of a modular cabinet system for multi-motor drives with a central supply infeed and a common DC link busbar, as used, for example, in the process industry, automotive industry, metal processing industry as well as in the crane and mining sectors. They are available in air-cooled version. As standard, they are installed side by side in a row.
SINAMICS S120 Cabinet Modules-2 include the chassis units from the SINAMICS S120 series in chassis‑2 format.
All drive components, from the supply infeed to the motor-side inverters, are configured in a clear, compact layout in the individual Cabinet Modules‑2. They can be flexibly combined – also with SINAMICS S120 Cabinet Modules – and optimally adapted to customer-specific requirements thanks to a comprehensive array of options.
The main components of the air-cooled system are as follows:
Active Line Connection Modules‑2 as a combination of Line Connection Module and Active Line Module with an Active Interface Module
Motor Modules
Standardized interfaces for both the power and the control connections facilitate configuration and installation. Communication between the power units and the central Control Unit takes place via DRIVE-CLiQ, the internal drive serial interface.
Compact, innovative mechanical design of the Motor Module for easier installation and removal, and with reduced footprint
Rated pulse frequency 2.5 kHz
Optimized derating
Innovative cooling concept
Condition monitoring
Very easy replacement of the device fan without removing the Motor Module from the control cabinet
The following table provides an overview of the voltage ranges and power ratings of the air-cooled SINAMICS S120 Cabinet Modules‑2 that are available.
The outstanding system features of the SINAMICS S120 Cabinet Modules‑2 provide the following advantages:
Process optimization with minimum outlay
A standard PROFIBUS or PROFINET interface and various analog and digital interfaces enable easy integration into automation solutions
Vector and servo control ensures that they fulfill the most exacting requirements regarding the accuracy and dynamic response of drives.
High level of reliability and availability
Individual modules and power components can be replaced quickly and easily, which ensures a higher level of plant availability
Energy saving during operation
The motor-side inverters are coupled via the common DC link and allow energy to be exchanged between motors that are motoring and generating. This means that energy is saved, there is less load on the supply infeed and line harmonics are reduced
Generally the line infeed is only dimensioned for the maximum energy required when motoring or the maximum current required when motoring – and not for the sum of the energy requirements of the Motor Modules connected to the DC link. As a consequence, for example, for conveyor belts or motor test stands with Motor Modules that are ltaneously operated in motoring and generating modes, a significantly smaller line infeed unit can be selected.
Minimal operative, maintenance, and servicing costs
Simple commissioning thanks to the menu-driven commissioning tools SINAMICS Startdrive or STARTER.
Optional, menu-navigated AOP30 advanced operator panel with plain text display and bar-type display of process variables.
All modules are easily accessible, making them extremely service-friendly
Space-saving design
Environmentally-friendly operation
The converters are exceptionally quiet and compact thanks to state-of-the-art IGBT power semiconductors and an innovative cooling concept
