Components
For operation, programming, and visualization purposes, the corresponding operating software
is already integrated into the CNC software for the NCU and therefore runs on the high-
performance NCU multi-processor module. The SINUMERIK PCU (e.g. SIMATIC IPC for
SINUMERIK) can be used for increased performance in the operating area.
Up to four distributed OPs can be operated on one NCU/IPC. The operator panel can be installed
as a thin client at a distance of up to 100 m.
The following components can be connected to the NCU:
• SINUMERIK operator panel front with TCU x 0.3/IPC and Machine Control Panel/Machine Push
Button Panel
• SIMATIC Thin Client (from rmware V2.0.1)
• SIMATIC CE panel
• SINUMERIK handheld units
• Distributed PLC I/O
– via PROFIBUS DP:
e.g. SINUMERIK I/O modules PP 72/48D and Analog Drive Interface for 4 axes ADI 4
– via PROFINET IO:
SINUMERIK I/O modules PP 72/48D PN and PP 72/48D 2/2A PN
• SINAMICS 120 drive system
• Feed and main spindle motors
– Synchronous motors 1FT / 1FK / 1FE1 / 2SP1
– 1PH / 1PM induction motors
– Linear / torque motors 1FN / 1FW6
