Variants - Siemens SINUMERIK 840D sl Manual

● SINAMICS 120 drive system
● Feed and main spindle motors
With the NCU 720.2 PN and NCU 730.2 PN, the SINUMERIK 840D sl is offering integrated
PROFINET functionality for the first time.
Supported:
● PROFINET CBA functionality
● PROFINET IO

Variants

The scalability of the hardware and software – both from a CNC perspective and in terms of
operation – means the SINUMERIK 840D sl can be used 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. The NCU 710 can be expanded
● On the NCU 720/730, the number of axes and/or the performance of the drive controller
● Use of an NCU 730 is recommended for maximum dynamics and accuracy in mold
● Since it has the highest PLC capacity, the NCU 730.2 PN represents the most advanced

The CBA functionality integrated in the NCU allows users to modularize machinery and
systems: Rapid real-time communication (up to 10 ms) between the controllers means
that systems lend themselves better to standardization and can be reused or expanded
more easily. Response to customer demands is faster and more flexible and startup is
simplified and speeded up by pretesting at component level.
As part of PROFINET, PROFINET IO is a communication concept that is used to
implement modular, distributed applications. PROFINET IO is based on Industrial
Ethernet and allows distributed field and I/O equipment to be connected to the central
processing unit.
256 PROFINET IO devices can be operated on the NCU as an IO controller.

performance.
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 5 NX10/15 modules in terms of drive controller
performance and the number of axes.
