SIEMENS SINAMICS DC MASTER is the drive system for basic applications and demanding DC applications. The use in a wide range of different sectors and complementary markets demands a high degree of scalability and the ability to expand the converter series over a wide range.
In order to be able to guarantee this versatile use, SINAMICS DC MASTER has a whole raft of new features:
The SINAMICS converter family
SINAMICS DC MASTER is a member of the SINAMICS converter family. The individual SINAMICS versions are based on a common platform, especially in the area of interfaces, tools and operator control & monitoring. All of the SINAMICS drives support the TIA philosophy and share common ways of engineering, communication and data management with the SIMATIC, SIMOTION and SINUMERIK automation systems from Siemens. When using these systems, automation solutions can be very simply generated using SINAMICS. As a result of the standard and seamless integration into the automation environment of Siemens, customers also profit from faster engineering and commissioning of the complete machine automation and drive technology. Further, training-related costs are reduced and support, service & maintenance and spare parts stocking are simplified.
SINAMICS DC MASTER converter
The SINAMICS DC MASTER series of converters includes the DC Converter and Control Module product versions.
The DC Converter includes built-in units for connection to a three-phase supply. These are used to supply the armature and field of variable-speed DC drives. The rated DC current range of the units extends from 15 to 3000 A and can be increased by connecting DC Converters in parallel.
Depending on the application, units for two-quadrant or four-quadrant operation and with integrated field power section are available. The units are autonomous as a result of the integrated parameterizing device and do not require any additional equipment for parameterization. All functions associated with open-loop and closed-loop control, as well as all monitoring and auxiliary functions, are handled by a microprocessor system. Setpoints and actual values can either be entered as analog or digital values.
The SINAMICS DC MASTER Control Module is the successor of the SIMOREG CM and is mainly used to retrofit and modernize DC drives.
SINAMICS DC MASTER converters are available in the following sizes (self-ventilated up to 125 A):
Rated DC current
Dimensions (W × H × D)
268 × 385 × 221
268 × 385 × 252
268 × 625 × 275
268 × 700 × 311
268 × 785 × 435
453 × 883 × 505
271 × 388 × 253
Less training time and costs and maximum number of identical parts through the extensive product range of the SINAMICS DC MASTER. The standard and seamless series of SINAMICS DC MASTER units addresses a wide current and voltage range. The series of units is designed for connection to three-phase line supplies. Furthermore, the units can also be connected to single-phase line supplies up to and including a rated DC current of 125 A.
Flexible expandability regarding functionality and performance. The extensive product range and the many options allow the DC Converter to be optimally adapted to customer requirements - both technically and economically. Different customer requirements, the type and number of interfaces as well as the computational performance and speed can be precisely fulfilled by selecting between either a Standard CUD, an Advanced CUD or a combination of both.
Plant and system availability are increased by being able to quickly and simply replace components. Replaceable components have been designed so that they can be quickly and simply replaced. The spare parts that are available can be viewed at any time, assigned to the serial number of the unit.
Easy commissioning and parameterization using interactive menus on the AOP30 Advanced Operator Panel with graphics-capable, backlit LCD and plain-text display, or PC supported using the STARTER commissioning tool (see "Tools and engineering").
Since the SINAMICS DC MASTER is already pre-configured at the factory, no device-specific parameters need to be set at all. The device is adapted to the relevant application by parameters in a fully electronic process. The units do not feature any potentiometers, switches, jumpers or DIP switches, which means that they can be put back into operation as soon as they have been serviced.
During the complete production process, all of the components are subject to comprehensive tests and checks. This guarantees a high functional safety.
Can be easily integrated into automation solutions, e.g. using a standard PROFIBUS communication interface and various analog and digital interfaces.
DC drive technology: Dynamic, rugged and cost-effective
Depending on the application, DC drives are frequently the most favorably-priced drive solution. They have many advantages when it comes to reliability, operator friendliness and operating characteristics. Just as before, there are some good technical and economic reasons for still using DC drives in many industrial areas:
Favorably-priced four-quadrant operation
Continuous operation at a low speed
Full torque and low torque ripple even at low speeds
