Siemens Answers with SINAMICS S120 Combi Drive Designed for Milling and Turning Applications

SINAMICS S120 Combi

SINAMICS S120 Combi offers the tried-and-tested SINAMICS functionality with an integrated drive concept specifically matched to compact turning and milling machines. With a multitude of technical highlights, SINAMICS S120 Combi sets new standards in this drive class. SINAMICS S120 Combi combines regenerative power supply as well as 3 or 4 motor modules for spindle and feed motors in one power module. In addition, SINAMICS S120 Combi features a connection terminal for a TTL encoder. This facilitates the spindle encoder’s direct and cost-efficient connection without additional hardware.

Note that the SINAMICS S120 Combi is available only when paired with Siemens SINUMERIK 828D and in some instances SINUMERIK 840D sl.

Features

  • Optimum dynamics and precision in a compact and integrated drive design
- with valuable features such as Dynamic Servo Control (DSC), 80-bit NANOFP accuracy and a high speed DRIVE-CLiQ communication interface

  • Maximum performance in minimum space

  • Uncompromising ruggedness
- caused by optimum protection against condensation, insensibility against weak power supply, and protection against short circuit, overvoltage, and ground faults.

  • Perfectly expandibility
- by easy connection of up to two additional SINAMICS S120 motor modules and by arbitrarily interpolation of the additional axes with the axes of SINAMICS S120 Combi.
