Safety and operating instructions for drive power converters
(as per: Low voltage guideline 73/23/EEC )
1. General
During operation, drive power converters may have, depending on
their protection class, live, bare, moving or rotating parts or hot
surfaces.
Unauthorised removal of covers, improper use, incorrect installation
or operation leads to the risk of serious personal injury or material
damage.
Further information can be found in this documentation.
All transportation, installation and initialisation and maintenance
work must be carried out by qualified personnel (comply with IEC
364, CENELEC HD 384, DIN VDE 0100, IEC 664 and 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 erection,
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 being installed in machines, the drive power converter cannot
be commissioned (i.e. implementation of the proper use) until it has
been ensured that the machine meets the provisions of the EC
directive 89/392/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 (89/336/EEC) is complied with.
The drive power converters meet the requirements of the low
voltage directive 73/23/EEC. The harmonised standards in prEN
50178/DIN VDE 0160, together with EN 60439-1/VDE 0660 Part
500 and EN 60146/VDE 0558 were applied for the drive power
converter.
Technical data and information for connection conditions can be
found on the rating plate and in the documentation, and must be
complied with.
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 that 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 4).
The electrical installation must be implemented as per 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 limit values specified in the EMC regulations is the
responsibility of the manufacturer of the system or machine.
6. Operation
Systems where drive power converters are installed must
be equipped, where necessary, with additional monitoring
and protective equipment as per the applicable safety
requirements, e.g. legislation concerning technical
equipment, accident prevention regulations, etc.
Modifications to the drive power converter using the
operating software are permitted.
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. Comply with the applicable
information signs located on the drive power converter.
All covers must be kept closed during operation.
7. Maintenance and repairs
The manufacturer documentation must be complied with.
These safety instructions must be kept in a safe place!

Supplementary Manual DeviceNet for NORDAC SK 200E About this document
Intended use of the frequency inverter
Compliance with the operating instructions is the requirement for error-free operation and
the fulfilment of any warranty claims. You must first read these operating instructions
before working with the device!
These operating instructions contain important information about service. They must
therefore be kept close to the device.
The field bus technology options described here are intended for use in combination with SK
200 E series frequency inverters. Use with other series is only possible with the SK TU4DEV(-C)) and SK TU4-DEV-M12(-C) technology modules for the SK 500E. The use of these
technology options with other devices is not permitted and can lead to their destruction.
The field bus technology options and the associated frequency inverters are devices for fixed
installation on motors or in equipment close to the motor to be operated. All data regarding
technical data and permissible conditions at the installation site must be complied with.
Commissioning (implementation of the intended use) is not permitted until it has been
ensured that the machine complies with the EMC directive 89/336/EEC and that the
conformity of the end product meets the machine directive 89/392/EEC (note EN 60204).

1 GENERAL INFORMATION ...................................................................................................... 8
Various technology options are available for Getriebebau Nord frequency inverters. General information
regarding these can be found in the relevant main manual of the frequency inverter series (e.g. Manual
BU0200 for the SK 200E frequency inverter series). Further information concerning special technology
options (e.g. the field bus module) is included in the relevant supplementary operating instructions.
This DeviceNet documentation contains supplementary descriptions concerning the DeviceNet options for
the SK 200E frequency inverter series.
The description of other optional modules (e.g. CANopen, Profibus DP) is dealt with in other supplementary
documentation.
In order to set up communication with DeviceNet, either an internal Customer Unit or an external
DeviceNet Technology Unit (according to the particular application) must be installed and connected.
The DeviceNet bus system
DeviceNet allows numerous different automation devices to exchange data with the frequency inverters.
PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in serial bit mode.
DeviceNet is primarily used for communication between sensor and actuator where system response needs
to be very fast. DeviceNet is primarily used where time critical, fast and complex communication between
the individual devices is essential. DeviceNet is a suitable alternative to expensive 24-volt parallel signal
transmission and transmission of measured values. This type of DeviceNet, which is optimised to speed, is
used for instance for operating frequency inverters on automation devices.

2.2 Electrical connection
WARNING
THE DEVICES MUST BE EARTHED.
Safe operation of the devices presupposes that qualified personnel install and commission it in
compliance with the instructions provided in these operating instructions.
In particular, the general and regional mounting and safety regulations for work on high voltage
systems (e.g. VDE) must be complied with as must the regulations concerning professional use of
tools and the use of personal protection equipment.
Dangerous voltages can be present at the motor connection terminals of the frequency inverter
even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields.
Ensure that the input voltage source is not live before setting up or changing connections to the
unit.
Make sure that the inverter and motor are specified for the correct supply voltage.
2.2.1 Cable glands
Both the SK 200E connection unit and the bus module provide extensive facilities for the connection of all the
required cables. The cables may enter the housing via cable glands and be connected to the terminal bar.
However, appropriate round plug connections (e.g.: M12 round plug connectors in M16 cable glands) may be
fitted in order to provide a plug-in solution.

Within the terminal box (unshielded cable section) the data cables (e.g. DeviceNet, system bus) must be
installed as short as possible and of equal length. Associated data cables (e.g.: Sys+ and Sys-) must be
twisted.
NOTE
In the customer unit, the DeviceNet is already installed with voltage isolation from the other
signal connections.
In case of EMC problems, voltage separation of the field bus supply, the digital inputs and
system bus interface and for the external technology unit also for the two additional digital
outputs should be provided.
NOTE
The cable shielding must be connected to the functional earthing1 (usually the
electrically conducting mounting plate) in order to prevent EMC interference in the
device.
In order to achieve this, for DeviceNet connections it is mandatory that the metallic metric
EMC screws are used for the connection of the DeviceNet shielding lead to the frequency
inverter or the housing of the technology unit. This ensures a wide area connection of the
functional earthing.

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.

2.2.2.2 Control connections for SK TU4-DEV(-…)
The double spring-loaded terminal bar of the technology unit is colour coded, and therefore indicates the three
different potential levels.
A separate voltage source can be used to supply the DOs. However, by bridging the 24V o
of the terminals of the system bus level 24V
and GND it is possible to implement the supply of the DOs.

Connection of up to 4 sensors and 2 actuators is made via the terminal bar. Alternatively, the
SK TU4-DEV

The DeviceNet module is a slave with “Group 2 Only Server” properties. Devices of this type can set up the
following pre-defined connections:
Bit-Strobe I/O connection (gateway operation is only possible to a limited extent in this mode)
The transfer rate for parameter access (requested message body format) is 8/8 (8 Bit Class ID / 8 Bit Instance
ID).
Clients which wish to use the gateway function of the DeviceNet must support fragmented transfer of the I/O
messages.
4.1.1 Gateway function
Up to four FIs and the bus module can be controlled via the bus module.
With "explicit messages transfer", the differentiation of the FI is carried out via various classes (see Section
"DeviceNet Communication”).
A single telegram is sent for the I/O messages (process data). This telegram contains the process data for all
four FIs and the bus module. With several FIs on the system bus, the data length exceeds the available 8
bytes, i.e. in gateway operation the data must be fragmented.
The required data size and its allocation to the individual FI is made in the module parameters (P160) to
(P165). These parameters are stored in an EEPROM in the module. The exact allocation is explained in the
section "DeviceNet Communication".
4.1.2 Parameterisation via DeviceNet
All modules and FI parameters can be accessed via DeviceNet. This is carried out via Class 100 to 181.
If parameters are accessed for FIs which are not connected, the bus module responds with the error message
“Resource unavailable”.
4.1.3 Timeout monitoring
Data traffic on the DeviceNet side is monitored via various timeouts defined by DeviceNet and/or P151.
P151 monitoring is triggered if the process data contact is interrupted or the process data in the USS profile
are transferred with an invalid control word. Transfer of process data with a data length 0 (PLC in programming
mode) also results in an error.
Sending of BitStrobe telegrams causes a reset of the P151 function, although no new process values have
been sent.
Parameter P513 is not evaluated in the bus module. The error behaviour of the individual FI can be defined via
this.
4.1.4 Input filtering
The four inputs are cyclically read every 250µs. This data is input into a filter routine. The minimum time for a
change of flank is 1ms.
BU 0280 GB Subject to technical amendments 35
Supplementary Manual DeviceNet for NORDAC SK 200E
4.2 DeviceNet process data
4.2.1 I/O messages
The assembly object in the DeviceNet module is static. However, it is possible to set various data lengths and
profiles in the assembly object via the parameters P160 to P165. The parameters are adopted by the bus
modules when the I/O message connection is set up.
With this it is possible to set data lengths of between 2 and 33 bytes. Any data size (in steps of 8 bits) can be
assigned to the individual FI. The lengths of the input and output data may be different.
The operating modes “Polled I/O” and “Change of state/Cyclic I/O” are fully supported by the module.
The operating mode “Bit Strobe” is subject to the restriction that the bus module may only return a maximum of
8 bytes. This must be noted for the setting of the parameters P160 and P161 – P165! Each MAC ID is
assigned a bit in the “Bit Strobe” telegram. This bit must be zero in order for the process data to be forwarded
to the FI. If the value is one, the last valid value is retained.
4.2.1.1 Transfer of 16 & 32 bit process data
The 16 and 32 bit process data must be sent in “Little Endian" format (see the following example).

4.2.1.2 Structure of the process data
Data for up to 5 devices is sent in the fragmented telegram. The transmission sequence corresponds to the
following illustration
Area 1 Area 2 Area 3 Area 4 Area 5
Bus module FI 1 FI 2 FI 3 FI 4
The data for the bus module and then for FI 1 to 4 are sent in sequence. If one of the devices is not
parameterised, the next area moves up. For example, if the bus module is not accessed, the first bytes are
assigned to FI 1.

value.
The structure of the control and status words can be obtained from the old documentation. Setting of the
setpoint and actual values is made via the FI parameters P543 to P548.

4.3.9 Class 100 to 181 – Access to FI and bus module parameters
All parameters of the bus module and the FIs connected to the bus module can be accessed via the
DeviceNet. The FIs connected to bus module can be accessed via various Class ranges. See following table.
DeviceNet Class Accessed device FI Offset
100 to 107 FI 1 0

120 to 127 FI 3 20
130 to 137 FI 4 30
181 Bus module (Class 180 – 189 reserved)
Coding of the FI parameters in DeviceNet format is carried out as follows:
All FI parameters can be accessed via this object. Access to bus module parameters or the parameters of
other modules on the system bus is not possible.
Access is obtained by setting the parameter number and the sub index. Then the parameter can be read or
written via attribute 3 or 4 of the parameter. The relevant FI is selected via the instance, i.e. with Instance = 1,
FI 1 is accessed, or with Instance = 4, FI 4 is accessed.
Inst. Attr. Description Type Access
1 to 4 1 Parameter number UINT Read/Write
1 to 4 2 Parameter Index USINT Read/Write
1 to 4 3 Read / write 16 bit parameter INT Read/Write
1 to 4 4 Read / write 32 bit parameter DINT Read/Write
Attribute 4 with 32 bit access is not contained in the EDS file, as otherwise the commissioning tools would
access a parameter via attributes 3 and 4. This results in an error message for an incorrect parameter size
(32Bit access to a 16Bit parameter).
In the EDS file and the bus module, attribute 1 is set to 0 as default. Parameter accesses with parameter 0 are
ignored and always receive a positive response, even if the relevant FI is not online. This prevents
unnecessary error messages.

5 Parameterisation
In order to enable communication via DeviceNet, the frequency inverter and the DeviceNet technology unit
must be parameterised accordingly.
With the DeviceNet protocol, the inverter parameters are mapped in the range 100 to 109:
- Class = 100 + parameter number / 100
- Attribute = Parameter number % 100
- Instance = SubIndex + 1
or
- Parameter number = (Class -100) * 100 + Attribute
- SubIndex = Instance – 1

The following list of parameters for the frequency inverter series SK 200E are directly relevant for the operation
of the frequency inverter via DeviceNet. A complete list of parameters for the frequency inverter (SK 200E) can

6 Error monitoring and error messages
6.1 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 of the “enable” on the frequency inverter (if no
acknowledgement),
4. by bus acknowledgement or
5. By P506, the 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 Structure of reference data
This section describes the cyclic data traffic between the bus master and the frequency inverter.
The reference data is divided into two sections:
PKW section (Parameter Code Value (parameterisation level))
PZD section (Process data (process data level))
Parameter values can be read and written via the PKW section of the reference data. All tasks which are
carried out via the PKW interface are essentially tasks for configuration, monitoring or diagnosis.
The PZD section serves to control the frequency inverter. The control word or status word as well as the
setpoint and actual values are transferred in the process data.
Access always consists of an order and a response telegram. In the order telegram, the reference data is
transferred to the slave. In the response telegram, the reference data is transferred from the slave to the
master. The structure of both telegrams is identical.

Fig.: Telegram traffic / structure of reference data area
Processing of the process data is carried out immediately in the FI (high priority), in order to ensure a rapid
reaction to control commands or a change in status can be transmitted to the master without delay.
On the other hand, the processing speed of the PKW data has a lower priority, so that processing may take
considerably longer.

16384 (4000 hex) is exactly 100% and -16383 (C000 hex) corresponds to -100%. Due to this resolution,
setpoints (depending on function) of up to ± 200% can be transferred.

The definition of these two setpoints corresponds to that of setpoint 1.
However, the transfer of a third (maximum 16 Bit) setpoint is only possible if the other two setpoints are also
16 Bit values.
If the transfer of a 32 bit setpoint is necessary (Example: setpoint position), this must be divided into two 16
bit values, i.e. into two PZDs (
position High and Low word).

“Bus function setpoint 3" (SK 200E: (P546[03]) or SK 500E (P548))
Example
If a position setpoint is to be transferred (Prerequisite: posicon inverter functionality) this can be performed
either as a 16 bit or 32 bit value. The resolution is always 0.001 rotations/step.
A value range of +32767 (= 32.767 revolutions) to -32768 (= -32.768 revolutions) is possible as a

words are required in order to transfer the position.
7.2.3.3 Actual value 1 (IW1)
The function of the actual value is set in the parameter "Function bus actual value 1" (SK 200E: (P543[01])
or SK 500E: (P543)) (see relevant frequency inverter manual).
In the order telegram, actual value 1 follows immediately after the control word. The actual value 1 is pre-set
to the transfer of the current output frequency of the frequency inverter (16 bit value).

The actual value is transferred as an integer in the range -32768 to 32767 (8000 hex to 7FFF hex), whereby
in the settings "actual frequency", "actual speed", "current" and "torque current", the values 16384 (4000
hex) exactly correspond to 100% and -16383 (C000 hex) correspond to exactly -100%. Due to this
resolution, setpoints (depending on function) of up to ± 200% can be transferred.
7.2.3.4 Actual values 2 and 3 (IW2/3)
If the PPO type 2 or 4 is used, in addition to actual value 1, a second actual value can be transferred in word
PZD3 and a third actual value in PZD4.

The definition of these two actual values corresponds to that of actual value 1.
If the transfer of a 32 bit actual value is necessary (Example: actual position), this must be divided into two
16 bit values, i.e. into two PZDs (
position High and Low word).

7.2.4 The 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 frequency inverter is in
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.
The following bits indicate the status of the frequency inverter:
Status Bit 6

8.1 System bus
With NORDAC inverter technology, units or modules communicate via a dedicated system bus. With the
launch 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 enable the user to make appropriate
adaptations.
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.: DeviceNet). This increases the number of possible subscribers on a field bus system (by a factor of 4)
with comparatively lower investment costs.
The system bus address of the bus modules (SK CU4address of the up to 4 frequency inverters which can be connected are set by means of DIP switches (see
manual BU0200) on the relevant frequency inverter, optionally between 32 / 34 / 36 and 38, whereby no
address may be doubly assigned within a system bus system.
… and SK TU4-…) is set to "30". The system bus
