The NX10.3/NX15.3 Numeric Control Extensions are used with SINUMERIK 840D sl for applications with large numbers of axes. NX10.3/NX15.3 allows the drive-end computing performance for the SINAMICS drives within the SINUMERIK 840D sl to be increased.

The modules have the same design as the SINAMICS S120 components. With a width of only 25 mm (1 in), the modules are also ideal for installation in compact machines.
