General description

The SINAMICS DC MASTER Control Module offers the optimum solution when retrofitting and modernizing existing DC drives. Contrary to the SINAMICS DC MASTER DC Converter, which comprises open-loop control, closed loop control and power unit, the Control Module is especially used if, as part of the modernization, the power unit of the existing plant or system should be kept. When it comes to quality, reliability and functionality, the SINAMICS DC MASTER Control Module is exactly the same as its predecessor - the SIMOREG CM; however, when it comes to functionality, it offers new features from the range of the SINAMICS DC MASTER.
There are many plants and systems with DC technology, which in the present version, can no longer be coupled to state-of-the-art automation systems. When retrofitting or upgrading these plants or systems, the existing motor, mechanical system and power unit are kept and the control unit is replaced by the Control Module. Therefore you can obtain 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 additional pre-assembled cable harnesses and mounting parts and components that are available, 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.
The SINAMICS DC MASTER Control Module sets itself apart as a result of a compact space-saving design - although it includes a field power unit. In order to optimally utilize the mounting/installation space in the plant or system the SINAMICS DC MASTER Control Module can be split depthwise.

Customer benefits

Motor, mechanical system and the power unit are kept, only the control section is replaced by the SINAMICS DC MASTER Control Module. In this case, the full functional scope of the SINAMICS DC MASTER series of units can be utilized - and you obtain an extremely favorably-priced, state-of-the-art DC drive which can be integrated into the TIA concept of the plant or system; and by using an Advanced Operator Panel AOP30, a favorably priced alternative is obtained to control cabinet measuring instruments.
This is how you can rejuvenate old plants and systems - and obtain an efficient retrofit solution.

Typical applications

The main applications for the SINAMICS DC MASTER Control Module include the retrofit and modernization of DC drives in existing plants and systems, especially high-rating drives.
In DC technology, there are many older systems, which still employee analog technology; these systems cannot be connected to a state-of-the-art automation system - or only with high associated costs.
Systems where it is difficult to obtain spare parts.
