1 The Decentral Concept
1.1 Introduction
Danfoss was the world's first company to manufacture and supply frequency converters for infinitely variable speed control of three-phase AC motors.
Until then, AC motors had to operate at the speed determined by the frequency of the main power supply.
Production of frequency converters started in 1968. The first frequency converter was also the first decentralised drive as it was placed next to the motor.
The first frequency converter was totally enclosed and filled with silicone oil for cooling, as semiconductors of that time were very inefficient. The enclosure
design was made for mounting the drive directly in the application next to the motor. Temperature, water, cleaning agents, dust and other environmental
factors were also no problem, even in harsh environments.
Semiconductors improved during the next decades. Air-cooling showed sufficient and oil cooling was abandoned. At the same time use of frequency
converters grew significantly. PLCs gained a footing for advanced application control and it became common practice to install all frequency converters
in one cabinet, rather than several places in the factory.
Continuing improvements in semi-conductors and related technologies - such as fieldbus technology - now again makes it feasible to consider installing
drives close to the motors, achieving the benefits of decentralised installation without the disadvantages from the first oil-filled frequency converters.
Development of automation in industry is based on the ability to send and receive data from the application needed to control the processes. More and
more sensors are installed and more and more data is submitted to the central PLC control. This trend depends on increased use of fieldbus systems.
Industrial sources often claim that up to 30 % of all drive installations will be installed decentrally within the next few years and the trend towards
distributed intelligent control is undisputed as more and more components and applications are developed for decentralised installation.
This book is a general introduction to basic features of decentralised installation philosophies for motor controls and differences from the centralised
concept. It will help you choose the most suitable concept and guide you through the process of selecting the appropriate products.
Finally we have included comprehensive information about the Danfoss decentralised products.

1.2 Decentral Design Benefits
In the following we will concentrate on describing decentralised installation of frequency converters, referred to here as motor controls.
There are two topologic concepts for the layout of motor control installations in a plant, in the following referred to as “centralised” and “decentralised”
installations. The two typologies are illustrated in the figure.
In a centralised installation:
-motor controls are placed in a central place
In a decentralised installation:
-motor controls are distributed throughout the plant, mounted
on or next to the motor they control
Decentralised does not mean
control cabinet free , but merely that their
enormous size can now be reduced thanks to innovative designs of the
components that will be placed decentralised. There will continue to be
a need for cabinets for power distribution and for overall intelligence, and
there are areas, particularly in the process industry with areas such as
explosion protection, where centralised cabinets continue to be the pre-
ferred solution.
Placing the advanced and reliable electronics needed to ensure a smooth,
responsive and economical operation of the motor next to – or on – the
motor facilitates modularisation and reduces cabling costs and EMC prob-
lems dramatically. Further benefits:
Illustration 1.1: Centralised versus decentralised installa-
tions
• Space-consuming motor control cabinets in long rows of centralised panels are eliminated
• Reduced efforts for building in and wiring long screened motor cables where special attention on EMC terminations is required
• Heat dissipation from power electronics is moved from the panel into the plant
• Standardised machine elements by modularisation reduces design time and time to market
• Commissioning is easier and faster
Decentralised motor control is rapidly gaining ground despite of the advantages of the centralised control concept:
• no need for extra space around the motor or close to the motor
• no control cable wiring into the plant
• independence of plant environment
1.2.1 Direct Cost Savings
Motor controls for decentralised installations must be built to meet the harsh conditions in manufacturing areas - especially such conditions found in the
food and beverage industry, where frequent wash downs are required. This of course increases the cost of the drive. This increase will be more than set
off by savings in expenses for cabinets and cables.
The cable saving potential is considerable, as will be demonstrated by the following example.

The figure illustrates an installation with motors distributed in a number of rows with several motors in each, as is the situation in for example parallel
bottling or baking lines in the Food and Beverage industry. This example shows the need for power cables from the centrally placed drives to the motors.
Illustration 1.2: Centralised installation
The drives are distributed equidistant with the distance L between each drive and the distance h between each row and also with a distance h from the
centralised power entry/cabinet location to the first row. There are n rows, and N drives in each row.

The Illustration 1.4 shows how the three-phase mains cable can be dis-
tributed with power looping from one motor (drive) to the next. The cable
saving potential is illustrated in Illustration xx. Given a distance of 10 m
between each motor and 20 m between each line, the potential cable
savings as a function of the number of motors and number of lines shows
of the figure.
Illustration 1.4: Cable saving potential in an illustrative in-
stallation
The saving potential in power cable length alone is substantial. The figure only illustrates the potential concerning power cables. Issues like unscreened/
screened cables and cable dimensions also ads to the benefits of decentralised installations.
Real case
Calculations on a specific, typical bottling line with 91 pieces of 1.5 kW motors, taking the cable dimensioning into account, showed the following saving
potential in cables and terminations:
• Cable terminations are reduced from 455 to 352
• EMC cable terminations are reduced from 364 to 182 by using motor controls with integrated service switches
• Power cable length reduced from 6468m to 1180m, a reduction of 5288m, and it is converted from screened cables to standard installation
cables
For details consult the following chapter on
Good installation practice .
1.2.2 Design Savings
End users want to postpone the final decision for new equipment - and to start production as fast as possible once a decision has been made. Payback
time and time to market must be reduced. This squeezes both the design phase and the commissioning phase.
Modularisation can minimise lead-time. Even manufacturers of large production equipment or lines use modularisation to reduce lead-time. Up to 40-50
% on the total time from design to running production can be saved.
The concept of modularisation is known from equipment like PC’s and cars. Modules with well-described functionalities and interfaces are used in these
products. The same concept can be applied to manufacturing, even though specific physical constraints play a role.

Production equipment is often built from different basic building blocks, each kind employed at several places in the installation. Examples include various
types of conveyor sections and machinery like mixers, scales, fillers, labellers, palletisers, packaging machines etc.
Illustration 1.5: Centralised cabinet
In a truly modular machine, all basic elements are self-confined and need nothing but electricity, water, compressed air or similar to function.
Modularisation therefore requires the distribution of intelligence to the individual sections and modules.
Sure, centralised installations can be modualarised, but then motor controls will be physically separated from the rest of the module.
Fewer cabinets, cooling and cable trays
Further savings will result from smaller cabinets, less cabinet cooling and fewer cable trays. Motor controls generate heat and are often mounted side by
side due to limited space, as illustrated in illustration 1.5. Forced cooling is therefore required to remove the heat.
Less Commissioning
Time spend commissioning at the end-user is significantly reduced using
decentralised solutions - especially when fieldbus communication is com-
bined with decentralised motor controls.
An Australian brewery has installed a line of 96 decentralised drives from
Danfoss connected by DeviceNet. An excessive amount of time was saved
as the commissioning of the variable speed drives was done in a few days.
The brewery estimates a saving exceeding AUD 100,000 compared to
traditional centralised installation.
Illustration 1.6: Decentralised brewery installation
Minimal Need for Additional Fieldbus Cables
Power cable savings are not offset by the additional cost for expensive fieldbus cables. Fieldbus cables will be extended in a decentralised installation,
but since fieldbus cables will be distributed in the plant anyway to connect sensors or remote I/O-stations, the extension will be limited. Decentralised
products from Danfoss can even be used as remote I/O stations to connect sensors to the fieldbus and reduce direct costs even more.

1.2.3 Ready-Installed Intelligence
The function of machinery and applications is typically tested at the suppliers. Machines are built, tested, calibrated and taken apart for transportation.
The process of rebuilding the application at the production site is considerably simplified by shipping it in modules with built-in motor controls, as rewiring
and testing is time consuming and calls for skilled personnel. Using ready-installed, decentralised installations reduces both time and risk as wiring for
motor, control and sensors are already in place and maintained during transportation. The need for highly skilled experts is reduced and local labour can
do a larger part of the installation. The commissioning costs and OEM resources on-site will be reduced.
1.2.4 Improved EMC
Electrical noise emitted is proportional to cable length. The very short - or eliminated - cable between motor control and motor in decentralised installations
therefore reduces emitted electrical noise. In decentralised installations, the machine builder normally mounts cables between motor controls and motors
in the machine leaving only power cables and fieldbus cables with no EMC emission to be installed at the production site. The risk of electrical noise from
motor controls to disturb other electrical equipment caused by a faulty installation will diminish and you avoid time-consuming fault finding in the com-
missioning phase, where time frame is tight.
1.2.5 Adapts to Standard and Special Motors
The FCD 300 is designed to control standard AC asynchronous motors.
Its flexibility allows it also to adapt to special motor types. An example is
the AMT feature (Automatic Motor Tuning). Combining Danfoss frequen-
cy converters to Danfoss geared motors makes it even easier as they fit
mechanically and the motor data are already stored in the FCD 300 mem-
ory. Combined motor-drives are provided pre-assembled directly from
Danfoss removing the need for mechanical fitting between motor and
control.
Illustration 1.7: Danfoss geared motor with FCD 300
1.2.6 Minimum Thermal Losses
Danfoss frequency converters feature the unique Voltage Vector Control (VVC) switching principle to generate motor voltages. Due to the VVC principle,
power losses in the motor are similar or less than the losses in a motor connected to mains. Thermal losses are minimised and overheat is prevented. At
the same time, the VVC principle ensures nominal torque at nominal speed and eliminates bearing currents.

1.2.7 Environmental Considerations
Drives – both centrally-mounted and distributed in the plant - are exposed to the environment. As motor controls handle high voltages and currents at
the same time they must be protected from dust and humidity so that they do not fail or break down. Both manufacturers and installers must take account
of this and Danfoss Drives have designed the decentralised products with a deep concern in both aspects.
Decentralised motor controls must also meet increasing demands in respect of hygiene levels in pharmaceutical industries and in food- and beverage
production in particular, where drives are exposed to cleaning agents for extensive periods of time, high pressure hosing and the like. The exterior of the
decentralised motor controls must be designed in such a way as to achieve this. Complicated heat sinks as illustrated in the figure must be avoided as it
is difficult to clean and not resistant to common cleaning agents.
Danfoss decentralised drives are designed to meet the requirements as shown in illustration 1.9. There are no hard-to-clean places, blind plugs have no
notches or indentations and two-layer robust surface treatment - tested to withstand commonly used cleaning agents - protects the housing.
Illustration 1.8: Non-cleaning friendly pin fin heat sink versus the easy to clean Danfoss solution
All corners are rounded to prevent dust sticking, and the distance between ribs allows high-pressure air cleaning, hosing and easy cleaning with a brush.
These concerns are more or less irrelevant if not applied to all elements and standard AC motors are normally designed without these concerns in mind
– stressed by integrated fans and cooling ribs both difficult to clean. Danfoss has met the challenge by designing a range of aseptic geared motors. These
motors have no fans and only smooth surfaces. An IP65 enclosure class is standard as is the special CORO coating resistant to acid, alkali and cleaning
agents used in for instance food and beverage industry. See the photo of an example of the aseptic geared motor series in Illustration 1.10.
Illustration 1.9: Aseptic Danfoss geared motor
Electrical contact can cause galvanic corrosion under wet or humid conditions. This can occur between housing (Aluminium) and screws (stainless steel).
One possible consequence is that screws become stuck and therefore impossible to unfasten in a maintenance situation. Galvanic corrosion will not be
found on Danfoss decentralised products, as the housings are fully coated and nylon washers underneath the screws protects the coating. The complete
coating and the unique gasket design prevent pitting corrosion, which can occur under gaskets.
Tightly enclosed equipment is susceptible to water build-up inside the enclosure. This is especially the case where equipment is exposed to ambient
temperature differences under wet conditions. As a decreasing ambient temperature lowers the surface temperature inside the enclosure, water vapour
VLT

tends to condensate. At the same time pressure inside the enclosure will drop and cause humid air from the outside to penetrate non-hermetic polymer
gasket materials and cable glands. When the enclosure heats up again, only the vaporised water will escape, leaving more and more condensed water
inside the enclosure. This can lead to water build-up inside the enclosure and eventually cause malfunction. The phenomenon is illustrated in the figure,
with a cyclic temperature fluctuation.
Illustration 1.10: The pumping effect in tight enclosures
Build-up of water inside enclosures can be prevented by membranes that prevents fluids to penetrate but allows for vapour to pass, as known from fabrics
used for outdoor clothing. A special cable gland with this kind of material is offered by Danfoss to eliminate this problem. The cable gland should be used
in applications exposed to frequent temperature fluctuations and humid environments as in equipment used only during daytime where the inside tem-
perature tends to fall to the ambient temperature during the night.

1.4.6 24 V External Supply
Back up of control supply with 24 V DC is available in EX and EB versions of FCD 300.
1.4.7 RFI Filter
FCD 300 has an integral 1A RFI-filter. The integral 1A RFI filter complies with EMC standards EN 55011-1A. See the sections Cable lengths and Cross
section
for further details.
1.4.8 Harmonic Filter
The harmonic currents do not affect power consumption directly, but they increase the heat losses in the installation (transformer, cables). That is why
in a SYSTEM with a relatively high percentage of rectifier load it is important to keep the harmonic currents at a low level so as to avoid a transformer
overload and high cable temperature. For the purpose of ensuring low harmonic currents, the FCD 300 units are fitted with coils in their intermediate
circuit as standard. This reduces the input current IRMS by typically 40 %.
1.4.9 Display Unit
On the FCD 300 unit there are 5 indicator lamps for voltage (ON), warning, alarm, status and bus.
In addition, a plug for connecting an LCP control panel is available as an option. The LCP control panel can be installed up to 3 metres away from the
frequency converter, e.g. on a front panel, by means of a mounting kit.
All displays of data are via a 4-line alpha-numerical display, which in normal operation is able to show 4 operating data items and 3 operation modes
continuously. During programming, all the information required for quick, efficient parameter Setup of the frequency converter is displayed. As a sup-
plement to the display, the LCP has three indicator lamps for voltage (ON), warning (WARNING) and alarm (ALARM). Most of the frequency converter's
parameter Setups can be changed immediately via the LCP control panel. See also the section entitled
The LCP control unit in the Design Guide.
