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.

correspond to the cable length of a segment. You can connect up to 9 RS 485 repeaters in

series.

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.

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.

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 control unit 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.

Rules for the laying of PROFIBUS cables

Laying of bus cables

During laying of the PROFIBUS cable, you must avoid:

7.8.5

Connecting PROFIBUS DP

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 control unit.

3. Screw the bus connector into place.

As the control unit 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.

CAUTION

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.

7.8.7

Operating the X136 interface as MPI

Applications

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

interface. The typical (default) baud rate is 187.5 Kbaud. A baud rate of up to 12 MBaud can

be set for communication with other CPUs. It should be noted, however, that a rate of

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

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.

7.9 Digital inputs/outputs

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

The following types of digital I/O are used:

● Digital inputs

● Bidirectional digital inputs/outputs

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.

9.1 NX10/15

Designs

Basically, the NX10/15 is integrated exactly the same way as the control unit into the

SINAMICS drive line-up in:

● Lateral mounting of NX 10/15 on the SINAMICS drive line-up (see also Manual control

units Supplementary System Components, Chapter 2.4 "Installation").

First, you must insert the supports into the cutouts of the NX that are attached to the line

module. Then the NX can be hooked in on the line module.

● NX10/15 with spacer directly on the rear wall of the control cabinet - standard.

The NX is secured with two M6 screws (6 Nm) to the mounting area.

Mounting an NX10/15 without spacers

In addition, you can secure the NX10/15 directly on the rear wall of the control cabinet even

without spacers. Using this method, you must dismantle the spacer attached as standard in

the delivery state.

Note

The spacer is secured with M3 torx screws on the NX. The screws must be screwed in with a

T10 screwdriver at a tightening torque of 0.8 Nm.

1. Remove mounting plate.

2. Remove angle plate.

3. Secure mounting plate on the NX.

4. Secure NX with two M6 screws (6 Nm) on the mounting surface.

CAUTION

The 80 mm ventilation spaces above and below the components must be observed.

DRIVE-CLiQ topology

NX10/15 components can be connected to the control unit via DRIVE-CLiQ. The following

rules apply to wiring of the NX10/15:

● Only one star topology is permitted between the NX10/15 and the control unit. This

means that only one NX10/15 can be operated per DRIVE-CLiQ port on a control unit.

● DRIVE-CLiQ ports not assigned to NX10/15 can be wired to other DRIVE-CLiQ

components.

● Once an NX10/15 has been connected and configured, you cannot simply insert it into a

different DRIVE-CLiQ port, as the addresses of the integrated drives are set permanently

from the point of view of the PLC. The following table illustrates this relation:

Dual fan/ battery module

10.1.1

Application

Functions of the dual fan/battery module

The dual fan/battery module can perform the following tasks:

● Cooling the CPU by means of two redundant fans.

● SRAM buffering if the SuperCap is insufficient.

The Control Unit monitors the temperature inside the module and the functioning of the fan.

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

● Fan warning: When one of the two fans has ceased to turn.

● Fan fault: When none of the fans turn.

If the software does not respond within approx. 1 minute the components are shutdown

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

Fans

If natural convection is not sufficient to ensure heat dissipation for the the

NCU 710.2/720.2/730.2, the fans integrated in the dual fan/battery module will be activated

when required.

● After switching the NCU on, the fan will be activated for a brief period (for testing

purposes) before turning itself off again.

● A temperature sensor on the NCU will switch the fan on if the air intake temperature

exceeds approximately 40°C.

● The fans will be switched off when the air intake temperature falls back below approx.

35°C.

● The fan is monitored during operation. In the event of a fault (stalled rotor or running too

slowly) a message is output.

Fans on the following Control Units run permanently:

NCU 720.2 PN and NCU 730.2 PN

NOTICE

The Control Unit cannot be operated without fans, i.e. the Control Unit will not power up if

the dual fan/battery module is not functioning.

Proceed as follows to replace the dual fan/battery module but only observe points 3 and 4 if

you want to replace the battery as well:

1. Gently push the dual fan/battery module backwards (by pressing on the pressure point) to

release the module from its front interlock (snap-in hooks).

CAUTION

Never pull the dual fan/battery module out abruptly without having released the

interlock. This would break the snap-in hooks and you would not be able to reinsert the

module.

2. Tilt the dual fan/battery module forwards at an angle and pull out the plastic guide from

the Control Unit cutout.

3. Remove the battery by first removing the plug connector and then taking out the battery.

4. Connect the cable plug connector of the new battery to the mating connector in the dual

fan/battery module and push the battery in.
