SIEMENS SINAMICS S120 High-Performance Low-Voltage Drive
Overview of SIEMENS SINAMICS S120 High-Performance Low-Voltage Drive
The SIEMENS SINAMICS S120 High-Performance Low-Voltage Drive boasts exceptional modularity, precision, and efficiency, making it a versatile solution for complex single-axis and multi-axis motion control tasks. Its modular design allows free combination of power and control components, covering 0.55–250 kW for AC/AC single-axis setups and scaling up to high-power configurations for multi-axis systems, adapting to diverse industrial demands. Equipped with CoolSiC™ technology, it reduces switching losses by 60% and supports 50kHz high-frequency PWM output, enhancing energy efficiency and performance.
Key strengths include servo, vector, and V/f control modes, delivering dynamic response under 1ms for high-precision regulation. Integrated safety functions (STO, SS1, SLS) meet SIL3/PLe standards, ensuring operational safety. Its compact design supports side-by-side mounting, with AirFlow+ cooling technology maintaining stable operation at Δ35K温升. Seamless integration with TIA Portal, PROFINET/PROFIBUS, and STARTER debugging software simplifies commissioning and reduces lifecycle costs.
Widely applied in machine tools, packaging, textile, and renewable energy industries, it excels in high-dynamic tasks like precision machining and linear speed control for battery production (tension fluctuation <1.5%). It also suits rolling mills, test benches, and automated assembly lines, supporting both continuous and cyclic operations. Its compatibility with induction and synchronous motors, plus flexible cooling options, makes it a reliable choice for boosting productivity across demanding industrial workflows. (Word count: 399)
