SINAMICS G120: The Smart Choice for Every Drive Control Scenario

Looking for a reliable, scalable, and high-performance variable frequency drive that delivers outstanding motor control and flexibility across industries? The SINAMICS G120 is engineered to meet a wide range of industrial needs—from basic conveyor control to high-performance process applications. With modular components like the PM240-2 power module and CU240E-2 PN control unit, and detailed guidance via the CU240E-2 PN manual, this drive system offers unmatched configurability, energy efficiency, and precise control for motor-driven systems.

Vector Control vs. V/f Control: Optimize with SINAMICS G120

One of the greatest strengths of the SINAMICS G120 lies in its dual-mode operation: vector control and V/f (voltage/frequency) control. Choosing the right mode depends on your application, and understanding the difference is key to maximizing performance.

Vector control provides dynamic, high-precision torque control, especially useful in applications like lifting equipment, cranes, and process automation where speed regulation and load adaptability are crucial. In contrast, V/f control offers a simpler, cost-effective solution ideal for fans, pumps, and conveyors that do not require fast torque response or precise positioning.

The SINAMICS G120 enables seamless switching between both control strategies. When integrated with a PM240-2 module and a CU240E-2 PN control unit, users can fine-tune motor behavior using real-time feedback loops, encoder signals, or simple open-loop control. This flexibility helps manufacturers and system integrators strike the perfect balance between performance and budget—backed by detailed configurations available in the CU240E-2 PN manual.

What Makes SINAMICS G120 the Right Choice for You
