Siemens Sinamics S120 AC Drives

High-performance modular converters of the series SINAMICS S120 They are represented by a wide range of models of uniaxial and multiaxial variations, excellent reaction speed and accuracy in operation. Due to their flexibility and functionality, they are able to adjust and ensure the most efficient execution of operations in a wide range of applications. In particular, for equipment for processing plastics, wood; machine tools of the textile, printing, paper industries; assembly units, test benches, mills, lifting equipment, etc.

The intelligent data processing system has three modes of operation: vector, servo and scalar control. Automatic adjustment, control of the engines according to the parameters of speed, torque and motion control. a reliable system for ensuring the safety of the drive, including in case of emergency situations.

All components of the drive system are communicated via the DRIVE CLiQ digital interface, as well as all formats of the line can be combined into a single complex for data collection and transmission. Also, this series in a multi-axis format is often used in conjunction with SIMOTION and SINUMERIK systems.
