Overview of SIEMENS SINAMICS G120 Low-Voltage Drive

The SIEMENS SINAMICS G120 Low-Voltage Drive boasts remarkable advantages in modularity, durability, and safety, making it a versatile solution for industrial automation. Its modular design combines configurable control units and power modules, enabling flexible customization with minimal spare parts and easy maintenance. Side-by-side mounting without derating saves cabinet space, while integrated DC bus reactors reduce harmonic interference and eliminate the need for additional进线 reactors. With a wide power range of 0.37–250 kW and multi-voltage support (200–240 V, 380–480 V, 500–690 V) with ±10% fluctuation tolerance, it adapts to diverse working conditions.

Equipped with advanced IGBT technology and closed-loop vector control, it ensures stable speed and torque regulation. Integrated safety functions (STO, SS1, SLS) meet SIL 2/PL d standards, safeguarding operations. Its 3C2-rated circuit board coating resists harsh environments, and it operates reliably at -10℃ to 60℃. Seamless integration with TIA Portal and support for PROFINET, PROFIBUS, and Modbus RTU enable flexible networked or standalone use, while built-in math logic eliminates the need for a separate PLC, cutting costs.

Widely used in pumps, fans, conveyors, and machining tools, it excels in continuous and discontinuous motion tasks. It is ideal for mechanical engineering, textiles, packaging, and chemical industries, handling both general and heavy-duty applications with 150% overload capacity for 60s. From small workshops to large production lines, its scalability and energy efficiency make it a cost-effective choice, enhancing productivity while ensuring operational safety and stability.
