The scalability of the hardware and software – both in the controller and control area –
provides the prerequisites for use of the SINUMERIK 840D sl in many sectors. The
possibilities range from simple positioning tasks up to complex multi-axis systems.
Application areas and performance
● As many as 6 axes can be implemented on an NCU 710. On the NCU 720/730, the
number of axes and/or the performance of the drive controller can be increased to 31
axes. This is achieved by using the NX10/15 module. The NCU 720/730 can be
expanded by up to 6 NX10/15 modules in performance for the drive controller and
number of axes.
● If there is a high demand for axes and channels, e.g., when using rotary indexing or multi-
spindle machines, the computing performance, configuration facilities and memory areas
of the control units can be combined via the CBE 30 option module (available soon), thus
becoming significantly extended.
● Use of an NCU 730 is recommended for maximum dynamics and accuracy in mold
making or in the high speed cutting sector.
The following table shows the essential features of the various control units:
