The distributed frequency inverter SINAMICS G120D belongs to the SINAMICS G series. It provides the same benefits such as modularity and an innovative safety technology (Safety Integrated), and has a special design and a high degree of protection. With an emmidiate effect it has new functions like positioning, extended safety functions and safety digital inputs and outputs. Furthermore it supports PROFIengergy as the first SINAMICS drive. Thanks to the wide range of power ratings up to 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-up 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 can be transferred and processed to a superoir control via Feldbus.
- Innovative functions
Positioning, capable of regenerative feedback into the line supply for energy saving, integrated safety technology and safety digital inputs and outputs
- Efficient and consistent solutions
via Totally Integrated Automation (TIA), consistency from SINAMICS through to the automation level. Possibility to built up all network topology due to the PROFINET media redundancy functions MRP (Media redundancy protocol), MRPD (Media redundancy with planned duplication) because the SINAMICS G120D is IRT-capable (Isochronous Real-Time)
- Faster engineering, fast commissioning
Commissioning and service times are also optimized thanks to the standard use of connectors for power, communications and sensor systems – optional MMC/SD card for parameter saving and mini USB integrated.

SINAMICS G120D – Typical Uses
SINAMICS G120D is suitable for the open-loop and closed-loop control of induction motors in a wide range of industrial applications and horizontal or vertical requirements of positioning. The drive is predestined to be used in complex conveyor systems – such as are found in automobile production with their numerous distributed single-motor drives. Further, the inverter is also suitable for high-performance applications in the airport sector, in the F&B sector (dry zones) and for electric suspended monorails in distribution logistical systems.
