2.2 System configuration
The SINUMERIK ONE combines CNC, HMI, PLC, closed-loop control and communication
tasks within a single PPU.
Components
For operation, programming, and visualization purposes, the corresponding operating software
is already integrated into the CNC software for the PPU and therefore runs on the high-
performance PPU module.
The following components can be connected to PPU:
● Distributed PLC I/O
– SIMATIC
e.g. ET200SP and ET200MP
● SINAMICS S120 drive system
● Feed motors, main spindle motors and direct-drive motors in synchronous and
asynchronous design:
– Servomotors: 1FT, 1FK
– Main spindle motors: 1PH, 1FE, 2SP1
– Direct-drive motors: 1FN3, 1FW6
● Handwheels
A maximum of three handwheels can be connected:
– Two handwheels via X143
– 1 using MCP and connection box.
● Increasing the number of axes
– NX10.3 / NX15.3
You can increase the number of axes connected to the NC using NX modules. Each
NX10.3 component can control up to 3 additional servo axes and each NX15.3
component can control up to 6 additional axes.
