System overview
1.3 Variants
NCU
Manual, 07/2007, 6FC5397-0AP10-2BA0 13
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.
256 PROFINET IO devices can be operated on the NCU as an IO controller.
The typical topology with Industrial Ethernet, illustrated above, can be integrated in
exactly the same way using PROFINET IO (or PROFINET components). Using
PROFINET machine control panels or operator panels means, of course, that diagnostics
is available as a PN device.
1.3 Variants
The scalability of the hardware and software – both in the controller and operating 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. The NCU 710 can be expanded
by up to 2 NX modules. One possible benefit would be improved servo drive 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 6 NX10/15 modules in performance for the drive
controller and 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.
● The NCU 730.2 PN is the new flagship of the SINUMERIK 840D sl and, with a
significantly higher PLC capacity than an NCU 730.2, represents the most advanced
configuration within the SINUMERIK 840D sl range.
The following table shows the essential features of the various Control Units:

2.1 Secondary electrical conditions
2.1.1 Connection Conditions
Compliance with the connection conditions
The controller is tested for compliance with the ambient conditions specified below. Fault-
free operation is only ensured if:
● These ambient conditions are maintained when storing, transporting and operating the
equipment.
● Original components and spare parts are used. This applies in particular to the use of
specified cables and plug connectors,
● the equipment is correctly installed and commissioned.
DANGER
The equipment may not be commissioned until it has been clearly identified that the
machine in which the controller is installed is in full conformance with the specifications
in EC Machinery Directive 98/37/EC.
Assistance and support
The connection conditions must be carefully maintained while setting up the complete
system. Please contact your sales representative for assistance and support.
2.1.2 Protective Separation as per EN 61800-5-1
Prerequisite
The complete system includes user interfaces (UIs) and interfaces for servicing, startup and
maintenance.

Application Planning
2.1 Secondary electrical conditions
NCU
16 Manual, 07/2007, 6FC5397-0AP10-2BA0
User interfaces (UIs)
UIs are all the interfaces that are freely accessible to the machine operator without the need
for tools or aids. These user interfaces are designed with safe isolation to EN 61800-5-1.
Interfaces for servicing, startup and maintenance
DANGER
The interfaces for servicing/installation and start-up/maintenance purposes are provided
without protective separation.
If necessary, these interfaces can be isolated safely using a supplementary adapter
(insulation voltage 230 V AC). Although these adapters are not included in the Siemens
scope of delivery, you can buy these parts from your local dealer, who will be happy to
advise you.
DANGER
Safe isolation can only be ensured if the system configuration specified below is strictly
adhered to. When mounting additional components (e.g. S7-300 FM, IP) with an end user
interface, please make sure that the end user interface has a basic insulation for at least
230 V AC.
The figure below shows the galvanic isolation of the 840D sl/SINAMICS S120/S7-300
system.

2.1.3 Grounding concept
Components
The SINUMERIK 840D sl system consists of a number of individual components which have
been designed so that the system complies with the appropriate EMC and safety standards.
The individual system components are:
● Numerical Control Unit (NCU):
● Machine control panel (MCP), pushbutton panel (MPP)
● Keyboard
● Operator panels (operator panel front + TCU/PCU)
● Distributor box and handheld unit
● S7-300 I/O with IM 153 interface module
Grounding measures
The individual modules are attached to a metal cabinet panel by means of screws. Make
sure that near the screws a low-impedance contact of the Control Unit with the cabinet panel
can be made. Insulating paints at the contact point must be removed. The electronics unit
grounds of the modules are connected to each other via DRIVE-CLiQ.

It is permissible to have a cluster of operator components for ground connection/PA.
Example: The Control Unit on the swivel arm.
It is sufficient in this instance to connect the ground connections of, for example, the PCU,
TCU and operator panel front using a cable and to route a shared grounding conductor to
the central ground connection in the control cabinet. Minimum cable diameter of 10 mm2.

NOTICE
If the connecting cable (e.g. PROFIBUS) is routed through several control cabinets, an
equipotential bonding conductor is to be connected to the Control Unit's "potential
connection". A finely stranded copper conductor with a 4 mm² cross-section must be used.
The equipotential bonding conductor is to be routed together with the connecting cable.

2.1.4 RI suppression measures
In addition to the protective grounding of system components, special precautions must be
taken to ensure safe, fault-free operation of the system. These measures include shielded
signal cables, special equipotential bonding, isolation, and shielding measures.
Shielded signal lines
● To ensure safe, fault-free operation of the system, it is essential to use the cables
specified in the individual diagrams.
● For digital signal transmission, the shielding must always be connected to the housings at
both ends.
Exception:
If non-Siemens devices are connected (printers, programming devices, etc.), standard
shielded cables grounded at one end can also be used. However, these devices must not
be connected to the controller during normal operation. However, if the system cannot
operate without them, then the cable shields must be connected at both ends.
Furthermore, the non-Siemens device must be connected to the controller via an
equipotential bonding cable.

Rules for routing cables
In order to maximize noise immunity for the complete system (controller, power section,
machine) the following EMC measures must be observed:
● The distance between signal lines and load cables must be maximized.
● If necessary, signal and load cables may cross one another (if possible, at an angle of
90°), but must never be laid close or parallel to one another.
● Only cables provided by the manufacturer should be used as signal cables from and to
the control unit.
● Signal cables may not be routed close to strong external magnetic fields (e.g., motors
and transformers).
● Pulse-loaded HC/HV lines must always be laid completely separately from all other lines.
● If signal lines cannot be routed a sufficient distance away from other cables, they must be
installed in grounded cable ducts (metal).
● The clearance (interference injection area) between the following lines must be kept to a
minimum:
– Signal line and electrical circuit signal line (twisted)
– Signal line and associated equipotential bonding conductor
– Equipotential bonding conductor and protective conductor (routed together)
