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.

CE-labelled drive power converters meet the requirements of the
Low Voltage Directive 2006/95/EEC. The harmonised standards for
drive power converters listed in the declaration of conformity are
used.

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 safety functions
which are described and 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 converter 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 connection

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 instructions can be found
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 applicable
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 5xxE

1 Introduction

1.1 General information

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.

1.2 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 TU3-PNT

 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

Performance

 100Mbit/s data communication

 Full duplex transmission

 Transmission of a maximum of five setpoints or actual values possible

PROFINET bus module for NORD frequency inverters SK 5xxE

2 Modules

2.1 SK 5xxE frequency inverters

By the use of various modules for display, control and parameterisation, the SK 5xxE can be easily adapted
to various requirements.

Alphanumerical display and operating modules can be used for simple commissioning. For more complex
tasks, various connections to a PC or an automation system can be selected.

The technology unit (Technology Unit, SK TU3-…) is connected externally to the front of the frequency
inverter and is therefore easy to access and replace at any time.

In the delivery condition (without technology unit) 2 LEDs (green/red) are visible externally. These indicate
the actual device status.

The green LED indicates that the mains voltage is present and operational, while a flashing code that
increases in speed shows the degree of overload at the frequency inverter output.

The red LED signals actual error by flashing with a frequency which corresponds to the number code of the
error (Manual BU 0500 Section 6).

WARNING

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

Installation of a technology unit separate from the frequency inverter is not possible. It must be
connected directly to the frequency inverter.

3.1.2 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 from 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 SK TU3- Ethernet module to the PE (Connection via the plug pin next to the 24V supply).

4.1 Process data

Control words and setpoints are transferred from the bus master / controller to the SK TU3-…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 I/O 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].

4.1.4 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 has to check the answers from the slaves as to whether the control command has been carried
out.

4.1.5 Setpoint and actual values

The meanings of setpoints are defined via the FI parameters P546 to P548 (SK 540E and above: P546[-01]
… [-05]). For the actual values, this determination is made via the FI parameters P543 to P545
(SK 540E and above: P543[-01] … [-05]).

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.

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.

Transmitted data (8 Byte)

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.

50% setpoint.

FI is set to "Standby" status, the motor runs up its
parameterised ramp to speed 0 and is switched off.

FI is set to "Operation enabled" status and controlled with a
25% setpoint.

4.1.7 Timeout monitoring

The PROFINET data traffic can be monitored with a watchdog with the aid of the time set in parameter
P513. 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.

4.2.1 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 TU3-PNT are assigned to Slot 2 and the
parameters of the frequency inverter to Slot 3.

 By means of a "Write Request" the data record is transferred to the IO device (SK TU3-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 TU3-PNT with "Read Request".

 The SK TU3-PNT responds with a "Read Response (-)", if processing is not yet complete.

 After processing of the parameter in the SK TU3-PNT the parameter order is concluded with the

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

4.2.3.2 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,…):

Array element Parameter set Index

If a parameter is not dependent on the parameter set, then Bit 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 4.2.3.1), in order
for the sub-index to be effective.

4.2.3.3 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 / 0.01 = 99.99 * 100 = 9999
Therefore the value 9999

4.2.4.4 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.

As the acceleration time has a frequency-internal resolution of 0.01sec, a parameter value of 10 / 0.01 =

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".

(Factory setting)

By selecting the appropriate value and confirming it with the ENTER key, the selected
parameter range is entered in the factory setting. Once the setting has been made, the value of
the parameter returns automatically to 0.

0 = No change: Does not change the parameterisation.
1 = Load factory settings: The complete parameterisation of the FI is reset to the factory

setting. All originally parameterised data are lost.

Parameterised IP address consisting of four bytes. In case of a change to the IP address (e.g.
with NORD CON), this is only saved by writing it to Index 4.

CAUTION: Saving is prevented if the IP address which is entered does not correspond to the

convention. If there are contradictions between the IP address and the mask (P161), the mask
is corrected automatically.

Deletion of the IP settings (IP+sub-net mask) is performed by entering IP 0.0.0.0.

[-01] = IP High (NET-ID)
[-02] = IP (NET-ID)

IP sub-net mask

(IP sub-net mask)

Parameterised IP mask consisting of four bytes. In case of a change to the IP mask (e.g. with
NORD CON), this is only saved by writing it to Index 4.

ATTENTION: Saving is prevented if the entered IP address is inconsistent with the IP address.
Example:

IP-Add: 192.168.20.200, IP mask: 255.255.255.0  Correct

IP-Add: 192.168.20.200, IP mask: 255.0.0.0  Error

The name is saved after the entry of a 0 at the end of the character string.

Test alarm

(Test alarm)

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

PROFINET bus module for NORD frequency inverters SK 5xxE

6 Error monitoring and error messages

According to the cause, frequency inverters and technology units generate appropriate messages if they
deviate from their normal operating status.

6.1 PROFINET error monitoring

An error in the frequency inverter (P700) or in the SK TU3-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 (P700 or P170) = Alarm number of the diagnostic alarm – 0x100

Example:

During operation, the error E10.3 (P700 Index 1 = 103) = Timeout occurs via the P513 monitoring. The
SK TU3-PNT sends a diagnostic alarm with the value 359 (= 100h + 103 = 256 + 103 = 359) to 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.

6.2 Error messages in the Bus module SK TU3-PNT

All SK TU3-PNT error messages are displayed in parameter (P170) of the bus module and trigger an error
in the connected FI. This is permanently stored in the FI error statistics. The error messages in the bus
module memory (P170) parameter are lost when the 24V supply voltage is switched off.

6.3 Error messages in the SK 5xxE 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 an appropriately programmed digital input (P420 ... P425 / P470 = Function 12),

3. By switching of the “enable” on the frequency inverter (if no
acknowledgement),

4. By Bus acknowledgement or

5. By P506, the automatic error acknowledgement.

The following error messages are directly associated with the Bus module SK TU3-PNT.
