Siemens SINAMICS G120D

Distributed drive syetem with possibility of Regeneration

The regenerative feedback capability of the PM250D Power Module in generating mode (electronic braking) means that energy is returned to the supply system and is not converted into heat in a braking resistor. This saves space, time-consuming dimensioning of the braking resistor as well as its wiring. Generated heat is also reduced. Further information can be found in the section Energy efficiency.

SINAMICS G120D

The PM250D Power Modules are generally prepared for Safety Integrated.


In conjunction with a standard Control Unit, the drive provides the safety function STO.

In conjunction with a fail-safe Control Unit, the drive can be turned into a Safety Integrated Drive with comprehensive safety functions.

The Safety Integrated functions are fully integrated in the drive system. They can be activated via fail-safe digital inputs on the Control Unit or via PROFINET or PROFIBUS with PROFIsafe.

The Safety Integrated functions are implemented electronically and therefore offer short response times compared to solutions with externally implemented monitoring functions.


Safety Integrated encoderless

The safety functions do not require a motor encoder; the implementation effort is minimal. Existing machines in particular can be updated with integrated safety technology without the need to change the motor or mechanical system.

The STO function can be used without any restrictions for all applications.

The SS1, SLS, SSM and SDI functions are only permissible for applications where the load can never cause acceleration. An encoder that is used for the purposes of motor control has no significance for the safety functions here.

    • Mechanical design, installation and retrofit of systems are significantly simplified as a result of the compact and space-saving design with an extremely low profile and with the same drilling dimensions for all power ratings; further, the dimensions are identical to those of the SINAMICS G110D distributed converter
    • Wide power range from 0.75 kW to 7.5 kW
    • The safety functions make it easier to integrate drives into safety-oriented machines or plants
    • The innovative circuit design (bidirectional input rectifier with "pared-down" DC link) allows the kinetic energy of a load to be fed back into the line supply system. This feedback capability provides enormous potential for energy saving because generated energy no longer has to be converted into heat in a braking resistor. Braking resistors and reactors are not necessary - this is a particular advantage in terms of the project engineering outlay, space requirement and installation costs for the high IP65 degree of protection
    • Easy commissioning and maintenance via a fieldbus or point-to-point via a mini USB parameterization interface and screen-based parameterization software and wizards
    • The same, standardized plug-in connections for the bus, power and I/O connections (ISO 23570) for the complete range of power ratings of SINAMICS G110D, SINAMICS G110M, SINAMICS G120D and SIRIUS M200D (motor starter)
    • Integrated positioning functionality supports process-related implementation of positioning tasks with a high dynamic response. Positioning can be implemented with an incremental or absolute encoder (SSI)
    • Increased degree of ruggedness and longer service life as the electronic modules are coated
    • Flexibility due to modularity for a future-oriented distributed drive concept with a high IP65 degree of protection
      • Module replacement under voltage (hot swapping)
      • The modules can be easily replaced, which makes the system extremely service friendly.
    • Simple, standard implementation of completely distributed plant and system concepts by using products in a scalable fashion:
      • SIRIUS M200D (motor starter)
      • SIMATIC ET 200pro FC‑2 (converter for distributed I/O)
      • SINAMICS G110D (converter for basic, conveyor-related applications)
      • SINAMICS G110M (converter for conveyor-related applications)
      • SINAMICS G120D (converter for demanding, conveyor-related applications)
    • Communications-capable via PROFINET / EtherNet/IP or PROFIBUS with PROFIdrive profile 4.1:
      PROFINET features:
      • Neighbor recognition (LLDP)
      • Ring topology possible (MRP (Media redundancy protocol), MRPD (media redundancy with planned duplication)
      • Isochronous real-time communication (IRT)
      • PROFIenergy
      • PROFIsafe
      • Diagnostics, interrupts
      • Shared Device
      • Attenuation meter (for FO variant)
    • Integrated fiber-optic interfaces (with CU240D‑2 PN‑F FO and CU250D‑2 PN‑F FO) for use in environments with harsh EMC conditions. These help to maintain stable communication and allow preventive maintenance of the connected PROFINET communication cable by means of an integrated attenuation meter.
    • Simple connection, engineering, data management as well as control of the converter in sophisticated plants and systems as a result of the consequential integration in TIA (Totally Integrated Automation)
    • High degree of operator friendliness by using the Intelligent Operator Panel (IOP‑2) to parameterize, diagnose, control (open-loop) and copy drive parameters
    • The ability to connect up to 6 sensors and up to 2 actuators to the Control Unit directly ensures that almost all the information relevant to the drive can be managed directly. Fail-safe Control Units can process signals from up to three fail-safe sensors and one fail-safe actuator. The CU240D‑2 Control Units are also equipped with two analog inputs, which can also be used as digital inputs. Local pre-processing of the signals relieves the fieldbus of the task and ensures a faster and more reproducible response time
    • Integrated EMC filter class A (acc. to EN 55011)
    • Integrated brake control, supported brake voltage 180 V DC (at line voltage of 400 V AC – otherwise Uline × 0.45 = brake voltage)
    • Integrated motor protection using a thermal motor model and evaluation of PTC, KTY, bimetal or Pt1000 temperature sensors
    • Software parameters for simple adaptation to 50 Hz or 60 Hz motors (IEC or NEMA motors)
    • Easy replacement of devices and time-saving copying of parameters to optional memory card
    • Engineering and commissioning with standard engineering tools such as SIZER for Siemens Drives (V2.9 and higher), STARTER (V4.3 and higher) and Drive ES ensure fast engineering and easy commissioning – STARTER is integrated in STEP 7 with Drive ES Basic with all the advantages of central data storage and totally integrated communication
    • Certified worldwide for compliance with CE, UL, cUL, RCM and Safety Integrated according to IEC 61508 SIL 2 and EN ISO 13849‑1 PL d and Category 3
