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.

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.

SINAMICS G120D distributed vector drive is employed in open-loop and closed-loop control of induction motors in a wide range of industrial applications. The drive is especially suited for complex conveyor systems – such as are found in automobile production with their numerous distributed single-motor drives. Further, the drive is also suitable for high-performance applications in the airport sector, in the Food & Beverage sector (dry zones), and for electric suspended monorails in distribution logistical systems.
