A potential fire hazard exists due to the energy being transferred in the equipment and the
work materials used.
All work on the electrical system must be performed after the system has been switched off
and disconnected from the power supply.
DANGER
Proper transportation, expert storage, installation and mounting, as well as careful
operation and maintenance are essential for this SINUMERIK device to operate correctly
and reliably.
The details in the catalogs and proposals also apply to the design of special equipment
versions.
In addition to the danger and warning information provided in the technical customer
documentation, the applicable national, local, and system-specific regulations and
requirements must be taken into account.
Only protective extra-low voltages (PELVs) that comply with EN 61800-5-1 can be
connected to all connections and terminals between 0 and 48 V.
Should it be necessary to test or take measurements on live equipment, then the
specifications and procedural instructions defined in Accident Prevention Regulation BGV
A2 must be adhered to, in particular § 8 "Permissible deviations when working on live
components". Suitable electric tools should be used.

Safety Information
1.1 Danger notices
NCU 7x0.2
10 Manual, 02/2011, 6FC5397-0AP20-0BA0
WARNING
Power cables and signal lines should be installed in such a way that inductive and
capacitive interference does not in any way impair the automation and safety functions.
WARNING
Repairs to devices that have been supplied by our company may only be carried out by
Siemens customer service or by repair centers authorized by Siemens. When replacing
parts or components, only use those parts that are included in the spare parts list.
Before opening the device, always disconnect the power supply.
Emergency stop/off devices which comply with EN 60204 / IEC 60204 (VDE 0113-1) must
remain effective in all automation equipment operating modes. The act of releasing the
emergency stop/off device must not cause an uncontrolled or undefined hot restart.
Additional external measures must be taken, or devices must be created that enforce a
safe operational state even when there is a fault (e.g. using independent limit value
switches, mechanical locks, etc.) at any location in the automation equipment where faults
might cause major material damage or even physical injury, in other words, where faults
could be dangerous.

Safety Information
1.2 ESD notices
NCU 7x0.2
Manual, 02/2011, 6FC5397-0AP20-0BA0 11
1.2 ESD notices
CAUTION
The modules contain electrostatically sensitive devices. Discharge yourself of electrostatic
energy before touching the components. The easiest way to do this is to touch a
conductive, grounded object immediately beforehand (for example, bare metal parts of
control cabinet or the protective ground contact of a socket outlet).
NOTICE
Handling ESD-modules:
When handling electrostatically sensitive devices, make sure that operator, workplace
and packing material are properly grounded.
Generally, electronic modules must not be touched unless work has to be carried out on
them. When handling PCBs make absolutely sure that you do not touch component pins
or printed conductors.
Touch components only if:
– You are permanently grounded via an ESD armband
– You are wearing ESD shoes or ESD shoe-grounding-strips, if ESD flooring is
available
Modules may only be placed on electrically conductive surfaces (table with ESD top,
conductive ESD foam plastic, ESD packaging bags, ESD transport containers).
Keep modules away from visual display units, monitors or TV sets (minimum distance
from screen 10 cm).
Do not bring ESD-sensitive modules into contact with chargeable and highly-insulating
materials, such as plastic, insulating table tops or clothing made of synthetic materials.
Measurements on modules are allowed only if:
– The measuring instrument is properly earthed (e.g., protective conductor) or
– Before measuring with a floating measuring instrument, the probe is briefly
discharged (e.g., touch the bare metal parts of the control housing).

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
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.
● PROFINET IO
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.
128 PROFINET IO devices can be operated on the NCU as an IO controller.

16 Manual, 02/2011, 6FC5397-0AP20-0BA0
2.3 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
by up to 2 NX modules. One possible benefit would be improved automatic speed control
performance.
● 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 5 NX10/15 modules in terms of drive controller
performance and the number of axes.
● Use of an NCU 730 is recommended for maximum dynamics and accuracy in mold
making or in the high speed cutting sector.
● Since it has the highest PLC capacity, the NCU 730.2 PN represents the most advanced
configuration within the SINUMERIK 840D sl range.

Control Units without PROFINET
The following figure shows an NCU 730.2 with its interfaces and control and display
elements (fault displays and status indicators). Please ensure that the structure of the NCUs
is virtually identical. There are only a few discrepancies, as follows:
● The NCU 710.2 has 4 rather than 6 DRIVE-CliQ interfaces.
● Deviations with NCU 710.2 and NCU 720.2:
– No cooling fins
– Layout of control and display elements behind the blanking plate (see Chapter
Position of operator control and display elements (Page 24))
