Simulate all SINAMICS S120 device types with minimal parameterization. Import standardized Functional Mockup Units (FMUs) into your simulation tool to validate concepts and accelerate engineering.

Pfeifer & Langen enhanced compliance, emissions monitoring and operational efficiency with Siemens’ long-term support — benefits strengthened by Siemens technologies such as the high-performance SINAMICS S120 drive system.

The SINAMICS S120 is a modular high-performance drive system designed for demanding motion-control applications. It supports single and multi-axis setups and is used in industries such as packaging, plastics, textiles, printing, woodworking, cranes, machine tools, rolling mills and test benches.

Yes. SINAMICS S120 can be configured and commissioned in TIA Portal via SINAMICS Startdrive (from version V15 onward). Motion control functions (speed, positioning, synchronization) can be executed through TIA Portal using SIMATIC S71500 controllers.

SINAMICS S120 supports vector, servo and V/f control modes, providing precise speed, torque and position control. It enables highly dynamic multi-axis synchronization and suits both continuous and cyclic highspeed processes.
