SINAMICS S120 combines forces with SINUMERIK CNC

sinamics s120-combi servo drive for cnc applications

SINAMICS S120-combi drive system for milling and turning applications

 SINAMICS S120 Combi offers tried-and-tested SINAMICS S120 functionality with an integrated drive concept specifically matched to compact CNC 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. This drive is the ideal basis for equipping compact standard machine concepts with a spindle power of 15 kW and up to five feed axes.

Important

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

 

The SINAMICS S120 Combi Power Module can be extended by the SINAMICS S120 Motor Modules in booksize compact format if the machine has more axes.

 

For machine concepts beyond the performance limit of the SINAMICS S120 Combi, the SINAMICS S120 modular drive system is available as an alternative for the SINUMERIK 828D CNCs.
