Siemens Answers with SINAMICS DC Master - the Next Generation of DC Drives Technology

The SINAMICS DC Master is the new member of the SINAMICS DC drives family, combining  the advantages of its predecessor, the SIMOREG DC Master, with the advantages of the SINAMICS family. Many of the SINAMICS tools and components so successful in 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 for 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 additional Control Unit for converters (Advanced CUD).

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 numerical 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.

Industry Benefits

 Reduced training time and expense

   The maximum number of identical components is reduced as a result of the extensive  product range of SINAMICS DC MASTER. The seamless and integrated series of SINAMICS DC MASTER Units encompasses a wide current and voltage range. The series of drives is designed to be connected to three-phase line supplies.

 Flexible expandability in functionality and performance

   The extensive product range and the many options allow the SINAMICS DCM to be optimally adapted to customer requirements - both technically and economically. Different customer requirements relating to the computational performance and speed can be precisely fulfilled with the ability to select between a Standard CUD, an Advanced CUD - or a combination of both.

 Plant or system availability increased by being able to quickly and simply exchange components

   Components have been designed so that they can be quickly and easily replaced. The available spare parts are assigned to the serial number of the drive unit

Simple commissioning and parameterization

    Menu-assisted at the AOP30 Advanced Operator Panel with graphics-capable LCD display and plain text display or PC-supported using the STARTER commissioning tool.

Simple integrated into automation solutions

    e.g. using the PROFIBUS communication interface provided as standard together with various analog and digital interfaces.

Typical Applications

  • Rolling mills

  • Cross-cutters and shears
