Модульность
SINAMICS G120 – это модульная система преобразования, включающая в себя множество функциональных устройств. Двумя основными устройствами являются
- Блок управления (CU) и
- Силовой модуль (PM)
Блок управления управляет и контролирует силовой модуль и подключенный двигатель в разных режимах. Он поддерживает коммуникацию с локальным или центральным контроллером и с контрольной аппаратурой или входными/выходными клеммами для прямого управления.
Силовой модуль питает двигатель в диапазоне мощности от 0.37 кВт до 90 кВт. Силовой модуль управляется микропроцессором в блоке управления. Современная технология IGBT с напряжением двигателя с широтно-импульсной модуляцией и выбранная импульсная частота используются для достижения очень надежной и гибкой работы двигателя. Большой диапазон защитных функций обеспечивает высокий класс защиты двигателя.
Кроме того, имеется большое количество дополнительных компонентов, таких как:
- Базовая панель оператора (BOP) для базового программирования и копирования параметров привода
- Сетевой фильтр, классы A и B
- Сетевые дроссели
- Тормозные резисторы
- Выходные дроссели для длинных кабелей двигателя
Safety integrated
Диапазон SINAMICS G120 включает в себя преобразователи для задач с ориентацией на безопасность. Конструкция всех силовых модулей практически безотказная. Можно получить Safety Integrated Drive, объединив силовой модуль с соответствующим надежным блоком управления.
Надежные частотные преобразователи SINAMICS G120 обеспечивают четыре функции безопасности, сертифицированные в соответствие с EN 954-1 кат. 3 и IEC 61508 SIL 2:
- Безопасный останов 1 (SS1)
- Безопасно ограниченная скорость (SLS)
- Безопасное управление тормозом (SBC)
- Безопасное отключение момента (STO)
Новая концепция охлаждения и лакировка электронных модулей
Значительное увеличение срока службы или периода эксплуатации достигается благодаря новой системе охлаждения и лакировке электронных модулей. Эти свойства базируются на следующих принципах:
- Отвод всех потерь тепла через внешний радиатор
- Электронные модули не располагаются в воздуховодах
- Естественное охлаждение электронных компонентов
- Станлартное конвекционное охлаждение блока управления
- Весь охлаждающий воздух направляется через радиатор

Дизайн
The SINAMICS G120 inverter chassis units are modular frequency inverters for standard drives. Each SINAMICS G120 comprises two operative units – the Power Module and Control Unit. Each Control Unit can be combined with each Power Module.
Guide for module selection
The steps to be taken for the selection of a complete SINAMICS G120 frequency inverter should be as follows:
|
|
1st
|
Selection of the appropriate Control Unit (in dependence of the required style depth of communication, hardware and software)
|
2nd
|
Selection of the appropriate Power Module (in dependence of the necessary performance and technology)
|
3rd
|
Selection of the optional additional components. A large number of components for expanding the system is available, e. g. line-side power components, DC link components, load-side power components, and supplementary system components. Please note that not every component is required for every Power Module (example: Braking resistors are not necessary for PM250 and PM260 Power Modules!). You can find the exact indications in the technical data tables of the respective components.

Control Units
The following Control Units and an MMC memory card are available as accessories for SINAMICS G120 inverter chassis units:
CU240 Control Units
The Control Unit performs closed-loop control functions for the inverter. In addition to control functions, the Control Unit can also perform other tasks which can be adapted to the relevant application by parameterization. A number of Control Units are available in different versions:
- CU240E
- CU240S
- CU240S DP
- CU240S DP‑F
- CU240S PN
- CU240S PN-F
MMC memory card (not available for Control Unit CU240E)
The parameter settings for an inverter can be stored on the MMC memory card. When the plant is serviced, it is immediately ready for use again after, for example, replacement of the frequency inverter and transfer of the memory card data. The associated slot is located on top of the Control Unit.
Power Modules
The following Power Modules are available for SINAMICS G120 inverter chassis units:
PM240 Power Modules
PM240 Power Modules (0.37 kW to 90 kW) feature an integrated brake chopper and are designed for drives without energy recovery capability. Generator energy produced during braking is converted to heat via externally connected braking resistors.
PM250 Power Modules
PM250 Power Modules (7.5 kW to 132 kW) use an innovative circuit design which allows line-commutated energy recovery to the supply. This innovative circuit permits generator energy to be fed back into the supply system and therefore saves energy.
PM260 Power Modules
PM260 Power Modules (11 kW to 55 kW) also use an innovative circuit design which allows line-commutated energy recovery to the supply. This innovative circuit permits generator energy to be fed back into the supply system and, therefore, saves energy. The PM260 Power Modules also have an integrated sine-wave filter that limits the rate of rise of voltage and the capacitive charge/discharge currents usually associated with converter operation.
Line-side power components
The following line-side power components are available for SINAMICS G120 inverter chassis units:
Line filters
The Power Module complies with a higher radio interference class with one additional line filter.
Line reactors (for PM240 Power Modules only)
A line reactor reduces the system perturbations caused by harmonics. This is valid in particular for low power supplies (system fault level uK > 1 %).
Recommended line components
This is a recommendation for further line-side components, such as fuses and circuit-breakers (line-side components must be dimensioned in accordance with IEC standards). Further information about the listed fuses and circuit-breakers can be found in Catalogs LV 1 and LV 1 T.
DC link components
The following DC link components are available for SINAMICS G120 inverter chassis units:
Braking resistors (for PM240 Power Modules only)
Excess power in the DC link is dissipated via the braking resistor. The braking resistors are designed for use with PM240 Power Modules. They are equipped with an integrated brake chopper (electronic switch).
Load-side power components
The following load-side power components are available for SINAMICS G120 inverter chassis units. This means that during operation with output reactors or LC filters or sine-wave filters, longer, shielded motor cables are possible and the motor service life can be increased:
Output reactors (for PM240 Power Modules only)
Output reactors reduce the voltage loading on the motor windings. At the same time, the capacitive charge/discharge currents, which place an additional load on the power section when long motor cables are used, are reduced.
The sine-wave filter (available soon, not available for PM260 Power Modules)
The sine-wave filter limits the rate of rise of voltage and the capacitive charge/discharge currents usually associated with converter operation. An output reactor is not required.
Available optional power and DC link components depending on the used Power Module

1) In connection with a PM250 or PM260 Power Module a line reactor is not necessary and may not be used.
2) In connection with a PM250 or PM260 Power Module a line-commutated regenerative feedback is carried out. A braking resistor cannot be connected and is not necessary.
3) PM240 FSF Power Modules from 110 kW (150 hp) on are only available without integrated filter class A. Therefore an optional line filter class A is available for lateral mounting.
General information on design
Frequency converters, consisting of Power Module (PM) and Control Unit (CU) and two base components at positions 1 and 2
- Max. two base components plus converter are possible.
- The line filter has to be mounted directly underneath the frequency inverter (position 1).
- With lateral mounting, the line-side components have to be mounted on the left side of the frequency inverter and the load-side components on the right side.
- Braking resistors have to be mounted directly on the control cabinet wall due to heating issues.

The SINAMICS G120 inverters meet the requirements of the Low-Voltage Directive 73/23/EEC.
Low-voltage directive
The inverters comply with the following standards listed in the EU gazette:
- EN 60204
Safety of machinery, electrical equipment of machines
- EN 61800-5-1
Electrical power drive systems with variable speed – Part 5‑1: Requirements regarding safety – electrical, thermal, and energy requirements

http://www.ul.com
Machine directive
The devices are suitable for installation in machines. Compliance with the machine directive 98/37/EEC requires a separate certificate of conformity. This must be provided by the plant constructor or the installer of the machine.
EMC directive
- EN 61800-3
Variable-speed electric drives
Part 3: EMC product standard including specific test methods
The modified EMC product standard EN 61800-3 for electrical drive systems is valid since 07/01/2005. The transition period for the predecessor standard EN 61800‑3/A11 from February 2001 ended on October 1, 2007. The following information applies to the SINAMICS G120 frequency inverters from Siemens AG:
- The EMC product standard EN 61800-3 does not apply directly to a frequency inverter but to a PDS (Power Drive System), which comprises the complete circuitry, motor and cables in addition to the inverter.
- Frequency inverters are normally only supplied to experts for installation in machines or systems. A frequency inverter must, therefore, only be considered as a component which, on its own, is not subject to the EMC product standard EN 61800-3. The inverter's Instruction Manual, however, specifies the conditions regarding compliance with the product standard if the frequency inverter is expanded to a PDS. The EMC directive in the EU is complied with for a PDS by observance of the product standard EN 61800-3 for variable-speed electrical drive systems. The frequency inverters on their own do not generally require identification according to the EMC directive.
- In the new EN 61800‑3 of July 2005, a distinction is no longer made between "general availability" and "restricted availability". Instead, different categories have been defined, C1 to C4, in accordance with the environment of the PDS at the operating site:
- Category C1: Drive systems for rated voltages < 1000 V for use in environment 1
- Category C2: Stationary drive systems not connected by means of a plug connector for rated voltages < 1000 V. When used in environment 1, the system must be installed and commissioned by personnel familiar with EMC requirements. A warning is required.
- Category C3: Drive systems for rated voltages < 1000 V for exclusive use in environment 2. A warning is required.
- Category C4: Drive systems for rated voltages ≥ 1000 V, for rated currents ≥ 400 A, or for use in complex systems in environment 2. An EMC plan must be created.
- The EMC product standard EN 61800‑3 also defines limit values for conducted interference and radiated interference for "environment 2" (= industrial power supply systems that do not supply households). These limit values are below the limit values of filter class A to EN 55011. Unfiltered inverters can be used in industrial environments as long as they are installed in a system that contains line filters on the higher-level infeed side.
- With SINAMICS G120 Power Drive Systems (PDS) that fulfill EMC product standard EN 61800-3 can be set up upon following the setup instructions.
- A differentiation must be made between the product standards for electrical drive systems (PDS) of the range of standards EN 61800 (of which Part 3 covers EMC topics) and the product standards for the devices/systems/machines, etc. This will probably not result in any changes in the practical use of frequency inverters. Since frequency inverters are always part of a PDS and these are part of a machine, the machine manufacturer must observe various standards depending on their type and environment, e.g. EN 61000‑3‑2 for line harmonics and EN 55011 for radio interference. The product standard for PDS on its own is, therefore, either insufficient or irrelevant.
- Regarding the compliance of limit values for line harmonics, EMC product standard EN 61800‑3 for PDS refers to compliance with EN 61000‑3‑2 and EN 61000‑3‑12.
- Regardless of the configuration with SINAMICS G120 and its components, the mechanical engineer can also implement other measures to ensure that the machine complies with the EU EMC directive. The EU EMC directive is generally fulfilled when the relevant EMC product standards are observed. If they are not available, the generic standards, e.g. DIN EN 61000‑x‑x, can be used instead. It is important that the conducted and emitted interferences at the line supply connection point and outside the machine remain below the relevant limit values. Any suitable technical means can be used to ensure this.
