How It Works

The Siemens 6SE6440-2UD22-2BA1 VFD operates by varying the frequency and voltage supplied to an AC motor, enabling precise speed and torque control. It converts the fixed-frequency AC input into variable-frequency AC output, providing dynamic motor control for efficient operation across diverse applications.

The vector control mode ensures rapid response to load changes and delivers high torque accuracy, making it ideal for demanding industrial tasks. Meanwhile, the V/Hz control mode serves as a simpler, energy-efficient option for less intensive applications. This drive enhances productivity, reduces energy consumption, and ensures reliable performance in challenging environments.
