SIEMENS SINAMICS G120 family of vector drive

The SINAMICS G120 family of closed-loop vector drives offers high levels of integrated safety, energy savings, and network connectivity. Available in ½ to 335 HP, this modular and scalable standard drive may be configured in a wide variety of designs to meet many industrial drive applications. In addition, built-in math and logic eliminate the need for a separate PLC.

The EN 60204 safety functions of the SINAMICS G120 are fully integrated into the drive and include Safe Torque Off, Safe Stop 1, Safety Limited Speed and Safe Brake Control. As a result, production plants obtain greater levels of safety while requiring less overhead to integrate the drives into fail-safe, automation, and drive environments. The SINAMICS G120 vector drive also complies with NFPA 79-2007

Modularity / flexibility to address application diversity

The SINAMICS G120 offers enhanced energy savings with regenerative power modules. The modules recover line commutated energy for all power ratings. It also eliminates the need for a pulsed resistor and brake chopper while reducing the control cabinet and cooling system requirements. Built-in portals for the PROFIBUS and PROFINET communications networks ensure exceptional drive performance that may be integrated to the field level.

SINAMICS G120C parks a lot in a compact space

SINAMICS G120C has been specially designed for machine manufacturers  looking for an economic, space-saving and easy-to-operate standard AC drive providing a surprisingly wide range of functions. This device combines compactness with superior power density and is characterized by fast installation and commissioning, user-friendly connections, and easy-to-use operating tools.

With its four frame sizes, the SINAMICS G120C covers a performance range of 0.75 to 25 HP (0.55 to 18.5 kW). The energy-efficient device serves the most common communication interfaces and is an integral part of Totally Integrated Automation.


Smallest Size Ease of Use Leading-Edge Technology
Compact, small drive, high power density Simple, optimized commissioning Energy-efficient, encoderless vector control – automatic flow reduction with V/Hz ECO
Quick mechanical installation (i.e. pluggable terminals) Effective, adequate parameter set (simple storing and cloning) Safety (STO) included at no additional cost
Side-by-side mounting without derating Usable with IOP, BOP-2 panels and USB connection PROFIBUS, CAN, Modbus RTU, and USS Communications available

Typical Applications

  • Machine building edit test
  • Mixers
  • Conveyors
  • Fans
  • Pumps
  • Compressors
  • Basic production machines


The SINAMICS G120D is the “distributed brother” of the popular SINAMICS G120 vector drive, sharing advantages such as modularity and innovative safety technology (Safety Integrated), while complementing the range with its well-conceived design. This vector distributed drive is particularly well suited for conveyor systems and in other applications where space is at a premium. Thanks to a wide range of power ratings up to 10 HP (7.5kW), almost all inverter-related applications can be consequentially designed without electrical cabinets. Digital inputs and outputs at the unit allow sensors and actuators to be directly connected at the drive

The input signals can either be directly processed in the inverter and autonomous (independent) local responses can be initiated – or the input signals may be transferred to a central control via PROFIBUS/PROFINET – where they are processed in the context of the complete plant or system.
