The following can be operated in an axis grouping with SINUMERIK 840D sl:

• Up to 2 NX10.3/NX15.3 components on the NCU 710.3B PN
• Up to 5 NX10.3/NX15.3 components on the NCU 720.3B PN/NCU 730.3B PN

The NX10.3/NX15.3 components are connected to the SINUMERIK 840D sl via DRIVE-CLiQ cables. This ensures that drive control remains high performant and clock synchronized. The communications interfaces on the SINUMERIK 840D sl remain available for other connections.
