industrialsecurity).

● Make sure that you include all installed products into the holistic industrial security concept.

1.4

Residual risks of power drive systems

The control and drive components of a drive system are approved for industrial and commercial

use in industrial line supplies. Their use in public line supplies requires a different configuration

and/or additional measures.

These components may only be operated in closed housings or in higher-level control cabinets

with protective covers that are closed, and when all of the protective devices are used.

These components may only be handled by qualified and trained technical personnel who are

knowledgeable and observe all of the safety instructions on the components and in the

associated technical user documentation.

When assessing the machine's risk in accordance with the respective local regulations (e.g.,

EC Machinery Directive), the machine manufacturer must take into account the following

residual risks emanating from the control and drive components of a drive system:

NCU 7x0.3 PN, NCU 7x0.3B PN

Manual, 06/2014, 6FC5397-1EP40-5BA1

Fundamental safety instructions

1.4 Residual risks of power drive systems

Unintentional movements of driven machine components during commissioning, operation,

maintenance, and repairs caused by, for example,

- Hardware and/or software errors in the sensors, control system, actuators, and cables

and connections

- Response times of the control system and of the drive

- Operation and/or environmental conditions outside the specification

- Condensation/conductive contamination

- Parameterization, programming, cabling, and installation errors

- Use of wireless devices/mobile phones in the immediate vicinity of the control system

- External influences/damage

In the event of a fault, exceptionally high temperatures, including an open fire, as well as

emissions of light, noise, particles, gases, etc. can occur inside and outside the inverter,

e.g.:

- Component failure

- Software errors

- Operation and/or environmental conditions outside the specification

- External influences/damage

Inverters of the Open Type/IP20 degree of protection must be installed in a metal control

cabinet (or protected by another equivalent measure) such that contact with fire inside and

outside the inverter is not possible.

Hazardous shock voltages caused by, for example,

- Component failure

- Influence during electrostatic charging

- Induction of voltages in moving motors

- Operation and/or environmental conditions outside the specification

- Condensation/conductive contamination

- External influences/damage

Electrical, magnetic and electromagnetic fields generated in operation that can pose a risk

to people with a pacemaker, implants or metal replacement joints, etc., if they are too close

Release of environmental pollutants or emissions as a result of improper operation of the

system and/or failure to dispose of components safely and correctly

Note

The components must be protected against conductive contamination (e.g. by installing them

in a control cabinet with degree of protection IP54 according to IEC 60529 or NEMA 12).

Assuming that conductive contamination at the installation site can definitely be excluded, a

lower degree of cabinet protection may be permitted.

Networking

The SINUMERIK 840D sl offers integrated PROFINET functionality. Supported:

● PROFINET CBA

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.

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.

2.4 Ordering data

Application areas and performance

● Up to 8 axes may be implemented on an NCU 710. The NCU 710 can be expanded by up

to 2 NX modules. One possible benefit would be increased 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 through the use of the NX modules. The

NCU 720/730 can be expanded by up to 5 NX modules for increased performance of the

drive control 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.

Dual fan/battery module

Functions of the dual fan/battery module

The dual fan/battery module has the following tasks:

● Cooling the CPU by means of two redundant fans.

● Buffering of the real time clock.

The temperature inside the NCU and the correct functioning of the fan are monitored. Fan

faults are displayed and can be read out by means of the diagnostic buffer.

● Fan alarm ⇒ alarm 2110 "NCK temperature alarm": if one of the two fans no longer rotates

or the speed is out of tolerance.

● Fan fault ⇒ alarm 2120 "NCK fan alarm type %1": if none of the fans rotate.

If the software does not respond within approx. 1 minute, the components are shut down

automatically and the status is indicated by means of the red SF LED.

You can find more information on the alarms in the Diagnostics Manual.

Description

3.5 Dual fan/battery module

Additional information on the diagnostics buffer is provided in the Function Manual Basic

Functions, see PLC signal DB10 DBX109.6 (fan temperature alarm).

Fans

The temperature is sensed at several locations within the NCU. The fan is automatically

switched in when the temperature thresholds set in the factory are exceeded. A hysteresis

function prevents frequent fan start/stop operations.

If natural convection is not sufficient to ensure cooling of the NCU, the fans integrated in the

dual fan/battery module are switched on when required (except for an NCU 730.3B PN with

PLC 319-3 DP/PN, in this case, the fan runs continuously):

● After switching the NCU on, the fan is activated for a brief period of time (function test)

before turning itself off again.

● The temperature is sensed at several locations within the NCU. The fan is automatically

switched in when the temperature thresholds set in the factory are exceeded. A hysteresis

function prevents frequent fan start/stop operations.

Note

The NCU cannot be operated without fans, i.e. it will not power up if the dual fan/battery

module is not functioning. The RDY LED flashes red/orange with 0.5 Hz, all other LEDs light

up orange. The state can only be exited by switching the NCU off.

Battery

A 3 V lithium battery is installed in the dual fan/battery module; this can be replaced when

required. The battery is pre-assembled with an approximately 4 cm long cable with plug

connector. The appropriate mating connector is attached to a small circuit board for connection

in the dual fan/battery module.

Note

Please dispose of used batteries in the specially provided collection points on site. This will

ensure that the batteries are recycled in the correct manner or treated as special waste.

Note

The backup time of a used type of battery is at least 3 years. Exceeding this backup time

risks loss of data.

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, Machine Push Button 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. Insulating paints on the mounting

points must be removed.

It is permissible to have a cluster of operator components for ground connection/PA.

Example: The control panel 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.

4.1.2

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 lines, special equipotential bonding connections, and isolation and shielding

measures.

4.1 Secondary electrical conditions

Shielded signal lines

● For safe and smooth operation of the system, the specified cables must be used. Please

refer to the chapter titled Connection.

● For digital signal transmission, the shield must have a conductive connection at both sides

of the housing.

Cable definitions

● Signal cables (example)

- Data cables (Ethernet, PROFIBUS, PROFINET, sensor cables, etc.)

- Digital inputs/outputs

- EMERGENCY OFF lines

● Power cables (example)

- Supply voltage 1 x 230 V AC or 3 x 400 V AC

- Motor cables

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:

● A minimum distance of 200 mm is to be observed between the signal lines and power cables.

● 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 use cables approved by Siemens for the signal lines from and to the NCU.

● Signal cables may not be routed close to strong external magnetic fields (e.g., motors and

transformers).

● If signal lines cannot be routed a sufficient distance away from other cables, they must be

installed in grounded cable ducts (metal).

Safety information

Note

The NCU is exclusively intended for installation in ESD-protected zones. The CE-associated

ESD interference immunity limit values can only be achieved via installation in the control

cabinet. Only make physical contact using appropriate ESD protective measures.

Open equipment

These modules are open equipment. This means they may only be installed in housings,

cabinets or in electrical service rooms that can be entered or accessed exclusively by means

of a key or tool. Housings, cabinets, or electrical equipment rooms may only be accessed by

trained or authorized personnel. An external fire protection casing is required.

NOTICE

The module can be damaged if power is connected to the NCU when installing/removing it

When installing the NCU, the system and the NCU must be disconnected (brought into a no

voltage condition).

Control cabinet installation

Please refer to the SINAMICS documentation for more details.

WARNING

Risk of fire through overheating if there are insufficient ventilation clearances

Inadequate ventilation clearances cause overheating with a risk for personnel due to smoke

and fire. Further, this can result in increased failures and a shorter service life of devices/

systems.

It is essential that you maintain 80 mm ventilation clearances above and below the NCU.

NOTICE

Risk of destroying components resulting from high discharge currents

The NCU or other PROFIBUS or PROFINET devices can be destroyed if significant discharge

currents flow through the PROFIBUS or PROFINET cable.

The DC power supply must be implemented as a circuit of Category PELV/DVC A according

to EN 61800-5-1.

WARNING

Inadequately fused supply cables can be life-threatening

In the case of supply lines > 10 m, protectors must be installed at the device input in order

to protect against lightning (surge).

The DC power supply must be connected to the ground/shield of the NCU for EMC and/or

functional reasons. For EMC reasons, this connection should only be made at one point. As

a rule, the connection is provided as standard in the S7-300 I/Os. In exceptional

circumstances when this is not the case, the ground connection should be made on the

grounding rail of the control cabinet; please also refer to /EMC/EMC Installation Guide.

Preparing the twisted pair cables

Function

The IE FC RJ45 Plugs are used to install uncrossed 100 Mbit/s Ethernet connections up to

100 m without the use of patches. Crossed cables can also be installed by swapping the

transmit and receive pair in a plug.

Prerequisite

When you set up your PROFINET system, you can cut the AWG 22 twisted pair cable on-site

to the required length, strip it with the Fast Connect Stripping Tool (for Industrial Ethernet),

and fit the Industrial Ethernet FastConnect RJ-45 Plugs using the cut-and-clamp technique.

Proceed as follows

Contacting of the FC cable versions is simple and reliable with the 4 integrated insulation

displacement contacts.

● When the plug case is open, color markings on the contact cover make it easier to connect

the cores to the insulation piercing connecting devices. The user can check that contact

has been made correctly through the transparent plastic material of the contact cover.

● The stripped end of the cable is inserted in the raised insulation displacement terminals

and the terminals are then pressed down to ensure reliable contacting of the conductors.

Note that an RS 485 repeater must be counted as a subnet node when determining the total

number of nodes to be connected. This is true even if the RS 485 repeater is not assigned its

own PROFIBUS address.

7.8 PROFIBUS DP

Connector features

The bus connector is used to connect the PROFIBUS cables to the PROFIBUS DP interfaces

(X126, X136), thus establishing a connection to additional nodes.

Only bus connectors with a 35° cable outlet should be used in order to ensure that the front

cover can be closed.

Note

Increased cabling space using PROFIBUS adapter connectors

The adapter connector is required if the bus cable is to be looped through at the left-hand

PROFIBUS interface (X126) of the NCU (2 PROFIBUS cables are connected at the

connector) and at the same time the Ethernet interface X120 is connected to a FastConnect

connector. When using the adapter plug, the PROFIBUS connector is higher, which creates

extra wiring space.

7.8.3

Connection components in PROFIBUS

Connection components

Individual nodes are connected by means of bus connectors and PROFIBUS cables.

Remember to provide a bus connector with a programming port at either end of the subnet.

This will give you the option of expanding the subnet if required, for example, for a programming

device.

Use RS 485 repeaters to connect segments or extend cable lengths.

Segments

A segment is a bus line between two terminating resistors. A segment may contain up to 32

nodes. In addition, a segment is limited by the permissible cable length, which varies according

to the transmission rate.

Terminating resistor

A cable must be terminated with its own surge impedance to prevent line disturbances caused

by reflections. Activate the terminating resistor at the first and last node on a subnet or segment.

The NCU must be either the first or the last node on the subnet.

Make sure that the stations to which the terminating resistor is connected are always supplied

with voltage during power-up and operation.

Introduction

PROFIBUS cables are connected to the X126/X136 interface by means of a bus connector.

Wiring the bus connector

1. Proceed as follows to connect the bus connector:

2. Plug the bus connector into the corresponding interface on the NCU.

3. Screw the bus connector into place.

As the NCU is located at the start or end of a segment, you must switch on the terminating

resistor ("ON" switch setting).

Note

Make sure that the stations on which the terminating resistor is located are always supplied

with voltage during booting and operation.

7.8.6

Disconnecting stations from the PROFIBUS

Removing the bus connector

You can remove the bus connector with a looped-through bus cable from the PROFIBUS DP

interface at any time without interrupting data traffic on the bus.

NOTICE

Data exchange on the bus can be interrupted!

A bus segment must always be terminated with the terminating resistor at both ends. This is

not the case, for example, if the last node with a bus connector is de-energized. Because the

bus connector takes its voltage from the node, this terminating resistor is ineffective.

Make sure that the nodes at which the terminating resistor is connected are always energized.

The X136 interface can also be operated as an MPI interface instead of a PROFIBUS DP

interface. 187.5 kbit/s is the typical (preset) data rate. A maximum data rate of 12 Mbit/s can

be set to communicate with other CPUs. However, it should be noted that the maximum data

rate is not supported by all CPUs (e.g. smaller SIMATIC S7 CPUs).

7.8 PROFIBUS DP

The following list provides examples of when using MPI (multi-point interface) may prove

effective:

● If a PC/PG with an MPI is being used

● If an MPI-type handheld unit is being used

Operate MPI like PROFIBUS

The information on wiring the connector (terminating resistors) for PROFIBUS and the rules

on the laying of cables for PROFIBUS apply to this interface as well. When carrying out this

procedure, consult the relevant references.

Connector features

The bus connector is used to connect the MPI bus cable to the MPI (X136). This enables you

to establish connections to additional nodes (e.g. PG or SIMATIC S7-CPU). Only bus

connectors with a 35° cable outlet should be used in order to ensure that the front cover can

be closed.

MPI bus cable

The PROFIBUS cable specifications apply here as well. Please note the relevant information

on setting up an MPI network.

Setting up an MPI network

Keep in mind the following basic rules when setting up an MPI network:

● When using the interface as an MPI interface, it is not possible to arrange additional control

for a drive in isochronous mode or to connect distributed I/Os to this interface.

● An MPI bus line must be terminated at both ends. This is achieved by activating the

terminating resistor in the MPI connector in the first and last station and deactivating the

other terminating resistors.

● At least one terminator must be supplied with 5 V.

This means that an MPI connector with an activated terminating resistor must be connected

to a device that is switched on.

● Spur lines (cables leading from the bus segment to the node) should be as short as possible,

i.e. < 5 m in length. Unused spur lines should be removed wherever possible.

● Every MPI station must be connected to the bus first and then activated.

To disconnect the station, it must first be deactivated. Then, the station can be removed

from the bus.

● Maximum cable lengths:

200 m per bus segment

2000 m total length with RS 485 repeaters

Connecting sensors and actuators

Digital inputs and outputs can be used to connect various sensors and actuators to the 14-pin

connectors X122 / X132 / X142 on the front panel. The interfaces are permanently assigned:

● X122 and X132: Drive

● X142: Control system

The following types of digital I/O are used:

● Digital inputs (isolated)

● Digital outputs

● Bidirectional digital inputs/outputs (only for drive terminals)

The assignment of I/Os to functions can be parameterized freely by the user. Special functions,

such as probe inputs (rapid inputs only) and cam outputs, can also be assigned to the inputs/

outputs.

The enables for the drive units and/or motors (Line Module, Motor Module) connected to the

NCU can be switched using the digital inputs.

Note

Terminal assignments

When commissioning the drive wizard, the digital inputs/outputs are correspondingly

preassigned functions.

For more information about terminal assignment, see:

● Commissioning Manual "IBN CNC: NCK, PLC, drive", Chapter "Communication interfaces

and terminal assignment"

● "Guidelines for machine configuration" System Manual, Chapter "Interfaces and their

terminal assignment"

Access to digital inputs/outputs

Note

The digital inputs/outputs of the drive terminals are updated in accordance with the set

PROFIBUS bus clock cycle of SINAMICS Integrated.

Using shielded cables

When using a shielded cable for the bidirectional inputs/outputs, the following options are

available for the shield connection:

1. Attach the cable shield to a grounded shielding bus immediately after the cable entry point

in the cabinet (strip the insulation off the cable for this purpose).

2. Continue routing the shielded cable as far as the module but do not make a connection to

the shield there.

Using a shield connection

1. Remove the fixing bracket of the shield connection.

2. Insert the cable and fasten the fixing bracket.

NOTICE

Ensuring the function of the digital inputs

An open input is interpreted as "low".

Only "rapid inputs" can be used as inputs for BEROs and probes.

Terminals G1 or G2 must be connected for the digital inputs to work. This can be done as

follows:

● Connect the ground reference of the digital inputs.

● A jumper to terminal M (note that these digital inputs are then no longer electrically

isolated).

Note

For a transient (brief) voltage interruption of the 24 V supply, the digital outputs are switched

inactive for this time.
