SINAMICS S120 drive system 
Only the SINAMICS S120 Line Modules and Motor Modules are used for drive control. Motor 
Modules can be used to connect servomotors as type 1FK7, 1FT7, and 1PH8 feed and main 
spindle motors. Type 1FW6 torque motors can also be connected.
Networking
The SINUMERIK ONE offers Industrial Ethernet and integrated PROFINET functionality.
PROFINET IO is supported:   
● As part of PROFINET, PROFINET IO is a communication concept that is used to implement 
modular, distributed applications. PROFINET IO is based on Industrial Ethernet and allows 
distributed field and I/O equipment to be connected to the central processing unit. 
● 128 PROFINET IO devices can be operated on the PPU as an IO controller.
