                    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.

Application Planning
2.1 Secondary electrical conditions

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.

2.1 Secondary electrical conditions

                   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.

                     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.

                       – Data cables (Ethernet, PROFIBUS, sensor cables, etc.)
                       – Binary inputs and outputs
                       – EMERGENCY OFF lines
                    ● Load cables (example)
                       – Low-voltage supply lines (230 V AC, +24 V DC, etc.)
                       – Supply cables to contactors (primary and secondary circuit)

2.2 Ambient Climatic and Mechanical Conditions

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)

                     Note
