Siemens SINAMICS G120

The modular inverter – space-saving, safe and robust

With the second generation SINAMICS G120, Siemens presents a modular inverter with higher power density and a space-saving frame size.The redesigned inverter series is now available in three voltage variants for connection to 200 V, 400 V and 690 V power supply networks.

Its modular design and wide range of power ratings extending from 0.55 kW up to 250 kW always ensures that you can configure the optimum inverter for your particular application. What is also clear: With the SINAMICS G120, you benefit from the wide range of possibilities that its modular design offers – including remaining flexible, saving costs thanks to the reduced spare part stocking, for example. And all of this is complemented by the high degree of user-friendliness – from installation through to maintenance. SINAMICS G120 is part of the comprehensive family of SINAMICS drives.

Power Modules:

Consists of two power modules

PM240-2:The Power Modules have a braking chopper (four-quadrant applications) and are suitable for a large number of applications in general machinery contruction.

PM250: The Power Modules are suitable for the same applications as the PM240 Power Modules. Any braking energy is directly fed back into the line supply (four quadrant applications - a braking chopper is not required).

Control Units:

Controlling of the motor according to the various control procedures is executed via the control unit. Apart from the control unit, further functions are available which can be adjusted by parameterization to the corresponding application. In the case of SINAMICS G120, several control units are available in various designs.

CU240E-2 series - for standard applications in general machinery.
CU250S-2 series - for performance applications in general machinery.
CU230P-2 series - the specialist for pumps, fans and compressors.

Accessories:

In addition the G120 can also be combined with a number of supplementary system components.

Basic Panel (BOP-2) - The simultaneous representation of parameter and parameter value as well as parameter filtration make the basic start-up of the drive extremely user-friendly, and in most cases you don´t need to see a printed list of parameters.
Intelligent Panel (IOP-2) - Color display, new functions and an even more functional design – with its new IOP-2. The new low-profile operator panel design and the integrated membrane keypad with a central control field are some of the features that really stand out.
Memory Cards - The parameter settings for an inverter can be stored on the memory card. Parameter settings can be written from the memory card to the inverter or saved from the inverter to the memory card
