1 Everlasting a fascination. dc drives

2 Inconceivable without DC drives. True values last forever. The same applies to DC drive technology even though for the last fifteen years now it has been predicted that it will no longer be used. Also in the future, Siemens Automation and Drives will still include this basic and straightforward drive technology in its portfolio. When all is said and done, it has reliably proven itself in day-to-day operations over many decades and it is therefore inconceivable that it will no longer be used. With our extensive know-how and with more than 125 years of experience, we will remain your reliable partner for everything to do with DC drive technology. Whether a new system or modernization, we can offer you ideal state-of-theart solutions. We are continually developing our DC drive technology. The best example: SIMOREG Control Module, the perfect retrofit solution for your DC drives and the most effective way to secure your capital investment over the long term.

4 SIMOREG DC-MASTER In DC technology, cost-effectiveness plays a decisive role. This is the reason that our SIMOREG DC-MASTER is the obvious choice. The drive converter distinguishes itself across the board: Increased power range up to 18,000 A, rated input voltages from 400 V to 950 V, integrated intelligence, simple and unified operator control philosophy, as well as functionality to support commissioning with self-optimizing current and speed controllers. And with an even higher degree of user friendliness: Menu-prompted parameterization using a PC and extensive diagnostic systems for troubleshooting. SIMOREG DC-MASTER fulfills international Standards and can be integrated into every automation environment. Its modular design means that it can be seamlessly expanded from standard applications up to highperformance solutions. SIMOREG DC-MASTER is a complete family of DC drives and is an integral part of Totally Integrated Automation (TIA) the extensive solution platform from Siemens and also unified with our AC drive systems. An extremely wide range of different versions is available. Thanks to their many advantages when it comes to reliability, operator friendliness and operating characteristics depending on the particular application they are often the first choice when a favorably priced drive solution is required. Advantages at a glance: Can be fully integrated into every automation environment Can be seamlessly expanded in a modular fashion from standard applications up to high-performance solutions Higher power range up to 18,000 A Rated input voltage from 400 V to 950 V Short and simple commissioning using fullyelectronic parameterization of all settings Unified operator philosophy Fulfills all of the relevant international Standards SIMOREG Converter Commutation Protector increased plant availability The SIMOREG CCP (Converter Commutation Protector) is used to protect a line-commutated SIMOREG DC-MASTER converter in inverter mode. In the event of a commutation failure, a large current is generated in the power supply system in feedback direction, or a transverse current in the converter. The Converter Commutation Protector limits these currents to a harmless value and so protects fuses and thyristors. And eliminates the expensive and timeconsuming need to replace such fuses following a commutation failure. Plant availability is therefore significantly increased. Top performance DC motors They still distinguish themselves: High-quality DC motors from Siemens. Always the ideal team when used together with our SIMOREG DC-MASTER drive converters. Everywhere, where favorably priced drive technology and highest availability are demanded. As variable speed drives, they prove themselves in almost every industrial sector. Siemens DC motors are available for every power rating: Non-compensated (shaft heights 100 to 180) and compensated (shaft heights 355 to 630) in the power range from 0.7 kw up to 1,550 kw. Additional advantages: Low shaft height with a high torque Modular design Suitable for use in dry indoor areas or outside Low-noise versions available Extremely low vibration levels and torque ripple

5 Timeless. SIMOREG CM our retrofit solution. You use DC drives? And your drives are still performing as they should but the closed-loop control no longer fulfills the high demands placed on state-of-the-art communication systems and the change in the automation environment? And you wish to fully utilize the benefits of fully-digital closed-loop and open-loop control technology? Then the SIMOREG Control Module (CM) is precisely the right solution for you. We can upgrade your drive converters to include the complete intelligence of the SIMOREG DC-MASTER without having to do away with your well proven power sections! As efficient leading-edge retrofit solution, our SIMOREG CM rounds off our family of SIMOREG DC-MASTER. These can be used to digitize your existing DC drives and bring them in-line with stateof-the-art technology at a low cost and without high space requirements. At the same time, SIMOREG CM allows you to take best advantage of your resources as neither motor, mechanical system nor power section must be replaced. Only the closed-loop control section is replaced. And not only this, SIMOREG CM is extremely service-friendly as all of the individual components are easy to access.
