DC drive system
Siemens DC drive solutions allow you to significantly reduce technology costs by delivering peak performance and integrated intelligence for maximum availability – such as the parallel switching interface for redundant operations, flexible expandability, quick and easy component exchange, easy commissioning and parameterization, and integration in a range of automation schemes.
Many of the same tools and components so successful in SINAMICS AC technology are now made available for SINAMICS DC drives. This series of drives sets itself apart as a scalable drive system – both for basic as well as demanding and sophisticated applications. For the standard closed-loop control, the DC converter is equipped with a standard control unit for converters (standard CUD). For applications demanding a higher computational performance and interfaces, the system can be expanded by an advanced CUD.

SINAMICS DCM drives formats
The SINAMICS DC Master series combines the open-loop and closed-loop control and power units in one device and therefore offer a compact, space-saving design. The AOP30 Advanced Operator Panel and the BOP20 Basic Operator Panel are available for commissioning and local operator control. The interfaces of the CUD and the number of digital inputs and outputs can be supplemented using additional modules – such as the TM15 and TM31 Terminal Modules.

SINAMICS DC MASTER Control Module offers the optimum solution when retrofitting and modernizing existing DC drives. Unlike the SINAMICS DC MASTER Drive, which comprises open-loop / closed-loop control and power unit, the Control Module is used solely as a component of modernization. There are many plants and systems with DC technology, which in their present condition can no longer be coupled with state-of-the-art automation systems, like Totally Integrated Automation. In retrofitting or upgrading, the existing motor, mechanical system and power unit may be retained and only the control unit is replaced by the Control Module. This allows for a state-of-the-art DC drive at an extremely favorable price with the full functional scope of the well-proven, fully digitized units from the SINAMICS DC MASTER series.
The flexible design, as well as the available pre-assembled cable harnesses and mounting components, simplify integration into existing plants and systems. Adaptation to the configuration and to the power data of the existing components is realized through simple parameterization. By using an Advanced Operator Panel AOP30, a favorably priced alternative is obtained to control cabinet measuring instruments. Using a compact space-saving design, the SINAMICS DC MASTER Control Module, which includes a field power unit, may be split depth-wise to allow even better utilization of the mounting/installation space.
