Safety and operating instructions for

drive power converters

(as per: Low Voltage Directive 2006/95/EEC )

1. General During operation, drive power converters may, depending on their

protection class, have live, bare, moving or rotating parts or hot surfaces.

Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of serious personal injury or material damage.

Further information can be found in this documentation. All transportation, installation, initialisation and maintenance work

must be carried out by qualified personnel (compliant with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 or DIN VDE 0110, and national accident prevention regulations).

For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the assembly, installation, commissioning and operation of this product and who have the relevant qualifications for their work.

2. Proper use in Europe

Drive power converters are components intended for installation in electrical systems or machines.

When installed in machines, the drive power converter cannot be commissioned (i.e. commencement of the proper use) until it has been ensured that the machine meets the provisions of the EC Directive 2006/42/EEC (machine directive); EN 60204 must also be complied with.

Commissioning (i.e. implementation of the proper use) is only permitted when the EMC directive (2004/108/EEC) is complied with.

Drive power converters with the CE mark meet the requirements of the Low Voltage Directive 2006/95/EEC. The harmonized standards stated in the Declaration of Conformity are used for the drive power converters.

Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.

The drive power converters may only be used for the safety functions which are described and for which they have been explicitly approved.

3. Transport, storage

Information regarding transport, storage and correct handling must be complied with.

4. Installation

The installation and cooling of the equipment must be implemented according to the regulations in the corresponding documentation.

The drive power converters must be protected against impermissible loads. Especially during transport and handling, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided.

Drive power converters have electrostatically sensitive components, which can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!).

5. Electrical connections

When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. VBG A3, formerly VBG 4).

The electrical installation must be implemented according to the applicable regulations (e.g. cable cross-section, fuses, ground lead connections). Further information is contained in the documentation.

Information about EMC-compliant installation – such as shielding, earthing, location of filters and installation of cables can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limiting values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

6. Operation

Where necessary, systems where drive power converters are installed must be equipped with additional monitoring and protective equipment according to the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc.

The parameterisation and configuration of the drive power converter must be selected so that no hazards can occur.

All covers must be kept closed during operation.

7. Maintenance and repairs

After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately, because of possible charged capacitors. Observe the relevant information signs located on the drive power converter.

Further information can be found in this documentation.

These safety instructions must be kept in a safe place!

PROFINET bus module for NORD frequency inverters SK 200E

1 General

Modern field bus systems, microcontrollers and communication networks have had a great influence on automation systems and have resulted in greater flexibility, availability and ultimately, also a reduction in costs.

The widespread use of PC-based control only became possible with the availability of field bus systems. With increasing control unit performance, the classic field bus ultimately became the limiting criterion for the entire system. It was therefore an obvious step to adapt Ethernet technology, which provides high rates of data transmission in IT applications, to the field of automation.

1.1 The bus system

As a physical transfer medium, PROFINET® transfers many years of experience with PROFIBUS-DP-V1 to Fast Ethernet. In addition to the conventional open Ethernet communication TCP/IP it enables real time communication of process data. PROFINET defines three communication classes, which provide different levels of efficiency and functionality:

 TCP/IP or UDP/IP communication without real time capability  Real time communication for process data (>1ms) RT  Isochronous real time communication for synchronised process data  IRT

Features of the SK TU4-PNT(-C)

 PROFINET IO real time communication (RT=Real Time and IRT=Isochronous Real Time)  Automatic address assignment via the IO controller using DCP (discovery configuration protocol)  Switched Ethernet  Autonegotiation (negotiation of transfer parameters)  Autocrossover (Transmission and reception cables crossed over in the switch)  Conforms with Class B, C  PROFINET IO bus cable connection via RJ45 plug - connector  Connection of I/Os and system bus via screw terminals and optionally via M12 round connectors  Display of specific PROFINET IO status with 2 LEDs  Specific DEVICE or FI status display with 2 LEDs  Eight integrated 24V inputs and two 24V outputs  Available as a version in a separate housing (optionally IP55 / IP66)  An interface (RS232/RS485) via an integrated RJ12 socket is available for parameter access by

means of the manual control unit SK PAR-3H or via NORDCON software.

Performance

 Electrically isolated bus interface 500V

eff

 100Mbit/s data communication  Full duplex transmission  Transmission of a maximum of five setpoints or actual values to the frequency inverter  Cyclic parameterisation (PPO 1 + 2) or acyclic parameterisation (Records)  PROFINET Bus Gateway solution → up to 4 frequency inverters can be connected to a PROFINET

bus module

 Almost unlimited participants in the PROFINET system possible (limited by the controller)

1.6 Version with protection class IP55 / IP66

NOTE

The modules for the IP66 design are identified by an additional "-C" and are modified according to the following special measures!

NOTE

For all versions, care must be taken that the cable and the cable gland are carefully matched. This is essential to ensure that the required protection class is maintained.

NORD SK 200E frequency inverters and the external additional modules are available in all sizes and powers in the protection classes IP55 (standard) or IP66 (optional).

The protection class IP66 must always be stated when ordering! There are no restrictions or differences to the scope of functions in either protection class. In order to

differentiate the protection classes, modules with protection class IP66 are given an extra “-C” (coated coated PCBs) in their type designation.

e.g. SK TU4-PNT-C IP55 version: The IP55 version of the external technology units is the standard version. Both versions (inverter-mounted

– as a supplement to the frequency inverter or wall mounted on the wall bracket) are available.

IP66 version: In contrast to the IP55 version the IP66 version is a modified option. With this design, both versions

(inverter-mounted or wall-mounted) are also available. The modules available for the IP66 version (adapter units, technology units and customer units) have the same functionalities as the corresponding modules for the IP55 version.

1 General

Special measures:

Impregnated PCBs, coated housing Diaphragm valve for pressure compensation on temperature changes. Low pressure test

 A free M12 screw connection is required for low pressure testing. After successful testing, a

diaphragm valve is inserted here. This screw connections is therefore no longer available for a cable gland.

NOTE

Modules should not be inserted or removed unless the device is free of voltage. The slots may only be used for the intended modules.

Mounting of the external technology unit remote from the frequency inverter is possible with the additional wall-mounting kit (SK TIE4-WMK-TU). However, a maximum cable length of 30m should not be exceeded.

The external technology units (SK TU4-...) cannot be operated without the BUS connection unit (SK TI4-TU-BUS)!

NOTE

Only one technology unit (SK CU4-... or SK TU4-...) can be connected to a system bus.

2 Assembly and installation

2.1 Installation and assembly

Only external technology units (Technology Units) are available for PROFINET IO. These are tailored to the NORD SK 200E frequency inverter series.

These are used to connect SK 200E series speed regulated drive units to overriding automation systems via the PROFINET IO field bus.

The technology units (Technology Unit, SK TU4-...) are externally attached to the SK 200E connection unit and are therefore easy to access. Mounting of the SK TU4-... separate from the frequency inverter is possible by means of the wall mounting kit SK TIE4-WMK-TU. The electrical connection to the SK 200E is made via the internal system bus. Optionally, 4 or 5 pin M12 round connectors are available (for installation on the BUS connection unit SK TI4-TU-BUS), which can be used for connection of the digital I/Os and the system bus cables.

NOTE

Looping of the 24V supply or GND is possible, however the maximum current load of 3A must not be exceeded with the module.

Only adjacent terminals (e.g.: 11/12) may be used for looping. Terminals 1/2 are preferentially for use with sensors and with maximum loads of 500mA.

Illustration of the terminal bar of the bus connection unit SK TI4-TU-BUS with allocation of functions

Potential level: system bus

Potential level: DOs

The double spring terminal bar is divided into 2 potential levels (system bus and digital outputs). A separate power source should be used for the supply of the DOs. However, by bridging 24V 2 and 0V 2 to

one of the terminals of the system bus level (24V and 0V) it is possible to implement the supply of the DOs. However, in this case it should be noted that there is an increased risk of introducing interference into the bus cables.

Connection of up to 8 sensors and 2 actuators is made via the terminal bar.

Connection example: SK TU4-PNT to SK 200E

In systems, electrical equipment is usually connected to a functional earth. This serves as a means to dissipate leakage and

interference currents in order to ensure EMC characteristics and must therefore be implemented according to high frequency technology aspects.

Simultaneous use of several diagnostic sockets with several diagnostic tools may lead to errors during communication. Therefore, only one diagnostic socket within a system bus network should be used.

ParameterBox SK PAR-3H

3.2 RJ12 Diagnostic socket

All participants which are coupled via a common system bus (field bus module / frequency inverter (up to 4 devices)) can be read out and edited/parameterised via an RJ12 diagnostic socket. This can be either the diagnostic socket of the frequency inverter or that of the BUS connection units. This provides users with a convenient facility to perform diagnosis and parameterisation from a central point, without having to access the particular frequency inverter at its location.

Table 9 RJ12 socket connections

The bus speed of the diagnostic interface is 38400 baud. Communication is carried out according to the USS protocol.

The ParameterBox SK PAR-3H is available as a diagnostic tool. The necessary connecting cables are included in the scope of

delivery of the ParameterBox. For a detailed description of use, please refer to Manual BU0040.

No special settings are required to set up communication with the individual diagnostic tools. The allocation of addresses is defined via the system bus addressing. The display of the diagnostic tool is

according to the following table, whereby the frequency inverter which is directly connected to the diagnostic tool is automatically assigned the address “0”.

Note Setting of the system bus address is carried out via two DIP switches (DIP 1 and 2) on the underside of the SK 200E- frequency inverter. For further details, please refer to the frequency inverter manual (BU 0220). The address of the BUS module is defined as “30”.

4 Commissioning

After installation of the components, and connection of the control and signal cables to the control terminal bar of the module the module must be integrated into the field bus. Then the PROFINET IO module must be implemented in the automation concept. In this section, the design of hardware in the SIMATIC Manager is shown as an example. Finally, some parameters for the PROFINET connection in the frequency inverter must be adapted.

4.1 Cabling

4.1.1 Topology

The SK TU4-PNT (PROFINET IO) modules can be connected to each other in star, tree, linear or ring topologies.

Fig. 4: Example of PROFINET IO linear topology

Fig. 5: Example of PROFINET IO star topology with switch

4.1.2 EMC

If EMC measures are not in place, high-frequency interference which is mainly caused by switching processes or lightning often causes electronic components in the bus participants to be faulty and error-free operation can no longer be ensured.

Correct laying of the bus cable dampens the electrical influences which may occur in an industrial environment. The following points must be observed:

 Implement long connections between bus participants by the shortest possible distances.  Only use plugs with a metal housing.  For the production of bus cables lay the shielding on as wide an area of the plug as possible.  With the parallel installation of bus cables, a minimum distance of 20 cm should be maintained from other

cables carrying a voltage greater than 60V. In particular, this must be observed for cables to motors or chopper resistors. This applies to lines laid both inside and outside of control cabinets.

 The minimum distances for parallel installation may be reduced by shielding cables carrying voltage or by

means of earthed metal dividers in the cable ducts.

 Connect each SK TU4 Ethernet module to the PE (PE terminal inside the module)

4.2 Parameter settings of the frequency inverter

4.2.1 Parameter settings of the SK 200E frequency inverter

The following settings must be made on the SK 200E:

 FI address (preferably set via DIP switches (DIP1 and 2)), if several FIs are connected to an

SK TU4-PNT (Gateway mode)

 Set the control and setpoints (preferably via DIP switches (DIP3)), or via parameter:

 Control via "system bus"  P509 = 3

 Setpoints via "system bus"  P510 = 3 or 0 if P509 = 3  Setting of setpoints via P546 [-01] … [-03]  Setting of actual values via P543 [-01] … [-03]

A precise description of the parameters can be found in Section 6.1 of this supplementary manual or in the SK 200E operating manual.

The parameters can be set with NORD parameterisation tools or via the PROFINET IO controller.

4.2.2 Parameter settings of the SK 500E frequency inverter

The following settings must be made on the SK 500E:

 Control via "CANopen"  P509 = 6  Setpoints via "CANopen"  P510 = 6 or 0 if P509 = 6  Setting of setpoints via P546, P547 and P548 (SK 54xE and above: P546 [-01] … P546 [-05])  Setting of actual values via P543, P544 and P545 (SK 54xE and above: P543 [-01] … P543 [-05])  Setting of system bus monitoring via P513 = 0.6s  Setting of the baud rate via P514 = 5 (corresponds to 250kB)  Setting of the system bus addresses via P515 [-01] = 32, 34, 36 or 38

For a detailed description of the parameters, please refer to the SK 500E operating manual. The parameters can be set with NORD parameterisation tools or via the PROFINET IO controller.

5.1 Process data

Control words and setpoints are transferred from the bus master / controller to the SK TU4-…bus module as process data and in return, the status word and actual values are sent to the bus master / controller from the FI. Transfer is carried out cyclically. The bus master / controller can access these process values directly, as they are stored in the IO area.

The length and structure of the process data is specified via the PPO types during the planning of the PROFINET network.

The allocation of the values transferred in the setpoint/actual value area of the FI is made via the parameters P543 to P548 or P543 [-01]…[-05] and P546 [-01] …[-05]..

5.1.4 FI Status Machine

The frequency inverter passes through a status machine. The changes between various states are triggered by the respective control commands in the process data control word. The actual status is returned in the process data status word.

After switching on, the inverter is in switch-on disabled status. This status can only be ended by transmitting the “Shut down (Off 1)” command.

The answer to a master telegram normally does not yet contain a reaction to the control command. The controller must check the answers from the slaves as to whether the control command has been carried out.

5.1.5 Setpoint and actual values

The meaning of setpoint values is determined via the FI parameters

 P546[-01] … [-03] (SK 2xxE)  P546 to P548 (SK 500E … SK 535E)  P546[-01] … [-05] (SK 54xE)

For the actual values, this determination is made via the FI parameters

 P543[-01] … [-03] (SK 2xxE)  P543 to P545 (SK 500E … SK 535E)  P543[-01] … [-05] (SK 54xE).

The transfer of setpoint and actual values is carried out by three different methods, which will be explained below.

Percentage transfer

The process value is transferred as a whole number with a value range of -32768 to 32767 (8000 hex to 7FFF hex). The value 16384 (4000 hex) is equal to 100%. The value -16384 (C000 hex) is equal to -100%.

For frequencies, the 100% value corresponds to the FI parameter "Maximum Frequency" (P105) and for currents, this is the FI parameter "Torque Current Limit" (P112) Frequencies and currents result from the following formulae.

Value = the 16Bit actual or setpoint value transmitted via Ethernet

Formula 1 Formation of 16Bit setpoint/actual value

Binary transmission

Inputs and outputs as well as Digital In bits and Bus Out bits are evaluated for each bit.

Transmission of positions

In the FI, positions have a value range of +/- 50000,000 rotations. A motor rotation can be divided into a maximum of 1000 steps. This scaling is independent of the encoder which is used.

The 32Bit value range is divided into a Low and a High word, so that 2 setpoint/actual values are required for transmission.

Table 19 Depiction of 32Bit setpoint/actual values

It is also possible to only transmit the Low component of the position. This results in a limited value range from +32,767 to -32,768 rotations. This value range can be extended with the aid of the gear ratio factor (P607 & P608). However, it must be noted that there is an according reduction in the resolution.

5.1.6 Example for switching the frequency inverter on and off

In this example, a frequency inverter will be operated with a setpoint (setpoint frequency) and an actual value (actual frequency). The "Maximum Frequency" is 50Hz.

Parameter settings:

 P105 = 500  P543 = 1  P546 = 1

Table 20 Example of setpoint specification

5.1.7 Timeout monitoring

The PROFINET IO data traffic can be monitored with a watchdog with the aid of the time set in parameter P151. If no further cyclical data is sent from the PROFINET IO controller, a module error is detected and set in the FI (E10.3).

Monitoring via the FI parameter P513 is also possible. This is triggered if the process data contact is interrupted or the process data is transferred with an invalid control word (Bit10 in control word = 0). This function is activated when the first valid process data telegram is received.

5.2.1 Function of PROFINET Records

The transfer of parameter data (Records) is performed acyclically. All parameters of the FI and the bus module can be accessed. For this the parameters of the SK TU4-PNT are assigned to Slot 2 and the parameters of the frequency inverters 1 ... 4 are assigned to Slot 3 ... 6.

The illustration below describes the function of Records

Fig. 10 Function of PROFINET Record

 By means of a "Write Request" the data record is transferred to the IO device (SK TU4-PNT) as a

parameter order.

 With "Write Response" the IO controller receives confirmation of the receipt of the message.  The IO controller requests a response from the SK TU4-PNT with "Read Request".  The SK TU4-PNT responds with a "Read Response (-)", if processing is not yet complete.  After processing of the parameter in the SK TU4-PNT the parameter order is concluded with the transfer

of the parameter response to the IO controller by means of "Read Response (+)".

The following table lists all the orders which can be transferred from the PROFINET IO controller to the frequency inverter. The right-hand column contains the response, which is normally sent (response label positive). Only certain response labels are possible, depending on the order label. In case of error (AK negative) the inverter will always supply the value 7 in the response label (AK) to the IO controller.

5.2.3.2 Parameter index field

The structure and function of the parameter index depends on the type of parameter to be transferred. For values which depend on the parameter set, the parameter set can be selected via Bits 8 and 9 of the Index (0 = parameter set 1, 1 = parameter set 2,...).

If the parameter to be processed is also an array parameter, then the sub-index of the required parameter can additionally be accessed via Bit 10 to Bit 15 of the sub-index (0 = array element 1, 1 = array element 2,…):

Table 27 Example : Address formation for array elements or parameters depending on parameter sets

If a parameter is not dependent on the parameter set, then Bits 8 – 15 are used for the sub-index. Please refer to the operating instructions for details of the structure of the individual parameters and which

values may be called up. If the sub-index is used, nos. 6, 7, 8 or 11, 12 must be used as the order label (see Section ), in order for the

sub-index to be effective (refer to Section 5.2.3.1).

5.2.3.3 Parameter value field

For each parameter, the transfer of the parameter value is always as a word (16 Bit) or double word (32 Bit) For negative values, the High bytes must be filled up with FF

hex

The parameter value is transferred as an integer value. For parameters with resolutions 0.1 or 0.01 the parameter value must be multiplied by the inverse of the resolution.

Example: A run-up time of 99.99 seconds is to be set.

99.99s  99.99 * 1/99.99 = 99,99 * 100 = 9999. Therefore the value 9999

ATTENTION

If parameter changes are made (i.e. requests via the PKW area by the control master), care must be taken that the maximum number of permissible writing cycles to the frequency inverter EEPROM (100,000 cycles) is not exceeded. I.e. continuous cyclical writing must be prevented.

For certain applications it is sufficient if the values are only saved in the RAM memory of the frequency inverter. The corresponding setting is made via parameter (P560) "Save in EEPROM".

5.2.4.4 Example of telegram structure with parameterisation via PPO1 or PPO2

When transferring parameter orders, it must be taken into account that the slave does not immediately respond to orders in the parameter channel of the master telegram, but a positive response can be delayed by one or more communication cycles. The master must therefore repeat the required order until the corresponding slave response is received. PPO type 1 or PPO type 2 must be selected.

The parameter (P102) "run-up time" (PNU = 102

dec

/ 66

) is to be set to the value 10sec in parameter set 3.

hex

(Only the PKW channel is evaluated.) As the acceleration time has an internal inverter resolution of 0.01sec, a parameter value of 10 / 0.01 = 1000

(3E8

) must be transferred.

Procedure:

1) Specify order label ("Change parameter value (array word)" → AK = 7)

2) Select parameter (P 102

0 = Monitoring OFF 1 = Auto, communication is only monitored if

an existing communication is interrupted. If a module which was previously present is not found when the network is switched on, this does not result in an error.

Monitoring only becomes active when the extension begins communication with the

FI.

2 = Monitoring active immediately; the FI

starts monitoring the corresponding module immediately after it is switched on. If the module is not detected on switch-on, the FI remains in the status

"not ready for switch-on" for

5 seconds and then triggers an error

message.

6 Parameters

In order to enable communication via PROFINET IO, the frequency inverter and the PROFINET IO technology unit must be parameterised accordingly.

SK 2xxE

-0.1 / 0.0 /

0.1 ... 100.0 s { 0.0 }

If the frequency inverter is directly controlled via the CAN protocol or via RS485, this communication path can be monitored via parameter (P513). Following receipt of a valid telegram, the next one must arrive within the set period. Otherwise the FI reports an error and switches off with the error message E010 >Bus Time Out<.

The inverter monitors the system bus communication via parameter (P120). Therefore parameter (P513) must usually be left in the factory setting {0.0}. Parameter (P513) must only be set to {-,0,1} if faults detected by the optional module (e.g. communication errors on the field bus level) are not to result in the drive unit being switched off.

0.0 = Off: Monitoring is switched off.

-0.1 = No error: Even if the bus module detects an error, this does not cause the

frequency inverter to be switched off.

0.1… = On: Monitoring is activated. Note: If a setting is made in this parameter in spite of this, values lower than 0.6s cause an error

in the FI due to the fixed definition of the system bus baud rate.

This parameter is used, e.g to trigger a diagnostic alarm from a slot during commissioning. A frequency inverter error can be simulated by entering the value of the error (e.g. link circuit overvoltage = E005.0  Value 50) in the slot of the relevant inverter (e.g.: Slot 3). An "incoming" alarm is triggered. If the value is reset to 0 the alarm is "outgoing".

Example:

Trigger alarm with error 5.0 on Slot 2: P163[-04] = 50  ChannelErrorType= 0x100+50=0x132

7 Error monitoring and error messages

NOTE

An error relating to the PROFINET IO communication is only displayed (P170 [-01]) for as long as it is active. Once the error is remedied, the message is automatically deleted and is archived in parameter (P170 [-02]) as the last error message.

If the power supply is interrupted before the error is remedied, the error is lost, i.e. it is not archived.

NOTE

The display of a bus error is shown in the operating display of the SimpleBox SK CSX-3H by means of the error group number E1000. In order to obtain the precise error number, the module information parameter (P170) must be selected. The current error is shown in Array [-01] of this parameter, the last error is stored in Array [-02].

7 Error monitoring and error messages

7.1 Error monitoring

The majority of bus module and frequency inverter functions and operating data are continuously monitored and simultaneously compared with limiting values. If a deviation is detected, the bus module or inverter reacts with a warning or an error message.

For detailed information, please refer to the relevant main manual of the frequency inverter. Errors cause the frequency inverters to switch off, in order to prevent a device fault. The following options are available to reset a fault (acknowledge):

1. Switching the mains off and on again,

2. by means of a correspondingly programmed digital input (SK 200E: (P420) [-…], function {12} or SK 500E: (P420 ... P425), function {12}),

3. by switching off the “enable” on the frequency inverter (if no digital input is programmed for acknowledgement),

4. by Bus acknowledgement or

5. by parameter (P506), "automatic error acknowledgement".

Visualisation of the inverter error codes is made via the frequency inverter (see relevant manual). Errors which are attributable to bus operation are visualised via the bus module. The precise error message is

displayed in parameter (P170).

7.1.1 Error monitoring details

Various monitoring functions are available to ensure reliable bus operation.  Timeout monitoring at the field bus level (PROFINET IO) by means of

o PROFINET watchdogs o Parameter (P151)

 Timeout monitoring at system bus level

o Parameter (P120) or (P513)

 Function monitoring within the bus module

o Parameter (P170)

With the aid of the "Timeout Monitoring" communication problems are detected, which are either related to general functionalities ("No bus communication") or are related to special modules ("Failure of a participant").

General process data monitoring of a Technology Unit (SK xU4-…) The parameter (P151) "Timeout external bus" generally monitors the existence of bus communication. If no

process data is received within the parameterised monitoring time (The content of the process data is irrelevant) the subscriber assumes that the bus communication to this subscriber is generally faulty and reports an error.

This error is also triggered if process data with an invalid control word (Bit 10 in control word = 0) is received. This function is activated when the first valid process data telegram is received.

General monitoring of frequency inverter process data SK 500E series frequency inverters offer the facility for monitoring the active bus interface by means of the

parameter (P513) "Telegram timeout". If the frequency inverter does not receive a telegram within the time entered here, it assumes that there is a general fault with the bus communication and reports an error.

Note: With SK 200E series frequency inverters, the function of this parameter is implemented by parameter (P120). Communication errors are therefore reported via the bus module. Parameterisation of (P513) is therefore not necessary. (P513) should be left at the factory setting.

Option monitoring With the parameter (P120) "Option monitoring", SK 200E series frequency inverters provide the facility for

monitoring connected technology units (SK xU4-…) with regard to their current functional status. Generally, this function corresponds to monitoring via parameter (P513). This parameter (P513) should therefore be left at the factory setting.

7.1.2 PROFINET error monitoring

An error in the frequency inverter (P700) or in the SK TU4-PNT (P170) results in a diagnostic alarm which is transmitted to the control unit as an "incoming event". The error value is coded as follows:

Error number (Value from P700 or P170) + 100 h = Alarm number of the diagnostic alarm

Example: During operation, the error E10.3 (P700 Index 1 = 103) = Timeout occurs via the P151 monitoring. The

SK TU4-PNT sends a diagnostic alarm with the value 359 (= 100h + 103 = 256 + 103 = 359) to the control unit.

If the error is no longer present a diagnostic alarm ("incident removed") is sent, which resets the error in the control unit.

With the aid of parameter P163, e.g. during commissioning, various alarms can be sent in order to test the operation of the control program.

Loss or switch-off of an inverter connected via the system bus: On loss of connection of the SK TU4-PNT to an FU connected via the system bus an alarm with the error

number 1000 (in the diagnostic buffer of the IO controller --> 256+1000=1256) is sent. This error is not saved in P170 and is only intended to give information about the loss of the FU as a switch-off of the connected FU may be part of the application.

NOTE

If earthing potential values are different, transient current may flow through shielding which is connected on both sides. This may be a danger to electronic components. Differences in potential must be reduced by means of adequate potential equalisation.

8 Additional information

8.1 Bus Configuration

In an industrial environment the correct installation of the bus system is particularly important in order to reduce potential interference. The following points are designed to help prevent interference and problems right from the start. The installation guidelines are not complete and applicable safety and accident prevention guidelines must be complied with.

8.1.1 Layout of the PROFINET IO bus cable

A PROFINET IO network can consist of an almost unlimited number of participants. In can be set up as a linear structure (NORD standard), as a tree structure, or as a ring system. There are practically no restrictions to the extent of the network, as each participant functions as a repeater and amplifies the bus signal. Only the distance between neighbouring participants is limited to 100m.

8.1.2 Cable material

Copper cables should be used for the bus. The cables must at least fulfil the Ethernet standard CAT-5.

8.1.3 Cable layout and shielding (EMC measures)

Correct laying of the bus cable dampens the electrical influences which may occur in an industrial environment. The following points must be observed:

 Implement long connections between bus participants by the shortest possible distances.  Connect each SK TU4-PNT module to the PE.  Only use plugs with a metal housing.  For the production of PROFINET cables, lay the shielding on as wide an area of the plug as possible.  With the parallel installation of bus cables, a minimum distance of 20 cm should be maintained from other

cables carrying a voltage greater than 60V. In particular, this must be observed especially for cables to motors or chopper resistors. This applies to cables laid both inside and outside of control cabinets.

 The minimum distances for parallel installation may be reduced by shielding cables carrying voltage or by

means of earthed metal dividers in the cable ducts.

Special attention should be paid to bending radii:

8.2 Cable glands and shielding connections

Nowadays, field bus systems are a normal part of plant technology. The sensitivity of these systems to electromagnetic interference (EMC) means that it is essential to protect bus systems from outside interference by means of uninterrupted or complete screening. Therefore the use of shielded cables and metal screw couplings or plug connectors has become standard. Assuming correct installation (e.g.: 360° screen connection - including at contact points, compliance with tightening torques, bending radii, IP protection classes (≥IP66),…), the operational reliability of the field bus system can be optimised.

The EMC effect of a cable shield is largely dependent on its contacts to the housing and its earthing on one or both ends. The shielding effect of a housing must not be influenced by incoming or outgoing screened cables. It is recommended that the shield is exposed directly at the point of entry and connection of the cable gland with the reference potential surface and the use of an EMC cable. At the same time this opening in the housing is "sealed" against the electromagnetic field. The connection from the cable shield to the housing must have a DC and and inductive resistance which is as low as possible. This depends on the frequency. This low contact resistance is achieved by the use of a ring-shaped 360° contacting of the cable shielding and short connections to the housing via the connecting thread.

8.2.1 Fixed connection (cable gland)

Metallic EMC cable glands with a shielding concept should be used to minimise EMC problems.

These special M16 x 1.5 EMC cable glands must be fitted in the relevant connection unit (SK TI4-…(-BUS)) of the frequency inverter or the PROFINET IO module.

Assembly

For the M16 x 1.5 EMC cable gland, 5 mm of the shielding of the cable /conductor is exposed and slightly spread out. The insulating foil of the Profibus cable must be cut off and must not be folded back.

Function When the pressure screw is tightened, the sealing insert presses the shielding mesh onto the cone of the

earthing insert. The entire circumference (360°) of the shielding mesh is contacted. The mesh ends in the cable gland. This produces a large area, low resistance conductive connection between the shield, the earthing insert and the screw fitting and the housing.

For further information regarding the correct installation of EMC cable glands, please refer to the relevant manufacturer´s data sheets.

8.2.2 Connection with M12 round plug connectors

In order to implement detachable connections, the cable connections for the system bus and for sensors and actuators, as well as for the 24V- supply voltage can be designed with plug-in connectors.

Here, freely adjustable M12 flanged connectors with metric M16 x 1.5 threads should be used for installation in the relevant housing (SK TI4-…(-BUS)).

This allows the use of angled or straight M12 round plug connectors for the cable connection.

If required, Getriebebau Nord GmbH can equip the device to be delivered accordingly, or can enclose the required plug with the delivery.

EMC compatible assembly is carried out in the same manner as for the assembly of the cable glands (Section 8.2.1 "Fixed connection (cable gland)").

8.2.3 Round plug connectors

Getriebebau Nord GmbH offers a selection of suitable plug connectors and couplings, which can be installed in the connection units of the frequency inverters or the field bus module, or enclosed with the delivery as required. The corresponding plug connectors, couplings and Y connectors are also commercially available. However, a limited selection can also be obtained from Getriebebau NORD GmbH.

Coding

Round plug connectors are coded. Coding is by means of a pin or a groove on the contact base. The most common codings are the so-called A and B coding. This serves to protect against incorrect coupling of the various field bus systems.

With the introduction of the SK 200E frequency inverter series and the associated components SK CU4-… and SK TU4-… functions and interfaces were implemented in this system bus, which allow users to make useful adaptations without having detailed knowledge of the function of the bus system (data allocation / error handling, etc.).

A decisive advantage is provided by the fact that the system bus is no longer restricted to a single inverter and a directly connected module, but rather that up to 4 frequency inverters can jointly use a BUS interface (e.g.: PROFINET IO). This increases the number of possible participants on a field bus system (by a factor of 4) with comparatively low investment costs.

The system bus address of the BUS modules (SK CU4-… and SK TU4-…) is set to "5". The system bus address of the up to 4 frequency inverters which can be connected are set by means of DIP switches (see manual BU 0200) on the relevant frequency inverter, optionally between 32 / 34 / 36 and 38, whereby no address may be doubly assigned within a system bus system.
