■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.

Finally we have included comprehensive information about the Danfoss decentralised products.

The decentral

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.

■Decentralised design benefits

In the following we will concentrate on describing decentralised installation of frequency converters and motor starters, 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

Decentral Solutions - Design Guide

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 problems dramatically. Further benefits:

• 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 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 preferred solution.

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

■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 thedrive. Thisincreasewillbemorethansetoffby 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.

The decentral

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.

Decentral Solutions - Design Guide

Decentralised cabling

The figure illustrates how the three-phase mains cable can be distributed with power looping from one motor (drive) to the next. The cable saving potential is illustrated in figure 4. Given a distance of 10m between each motor and 20m between each line, the potential cable savings as a function of the number of motors and number of lines shows of the figure.

Cable saving potential in an illustrative installation

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.

■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.

Fewer cabinets, cooling and cabletrays

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 Figure 6. 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 combined with decentralised motor controls.

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.

concept

The decentral

Decentralised brewery installation

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.

■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.

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.

■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

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

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.

■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 commissioning phase, where time frame is tight.

■Adapts to standard and special motors

Danfoss’ decentralised motor controls, FCD 300 and

DMS 300, are designed to control standard AC asynchronous motors. Their flexibility allows them also to adapt to special motor types. An example is the AMT feature (Automatic Motor Tuning) in the FCD 300. Combining Danfoss frequency converters to Danfoss geared motors makes it even easier as they fit mechanically and the motor data are already stored in the FCD 300 memory. Combined motor-drives are provided pre-assembled directly from Danfoss removing the need for mechanical fitting between motor and control.

motoraresimilarorlessthanthelossesinamotor 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.

Slim DC-links

It takes two steps to convert the frequency to vary the speed of an AC motor: A rectifier and an inverter. As the rectifier itself produces a rippled DC voltage, a capacitor is often introduced to smoothen the voltage supplied to the inverter. A link between rectifier and inverter with only a small capacitor to even out the voltage is called a "slim DC link". With a slim DC link, the inverter will not be able to provide quite the same voltage amplitude as supplied by the mains supply, leading to lower efficiency. A special pulse-width-modulation can be used to compensate the ripple from a slim DC link. In this case the output voltage for the motor still does not reach the rated supply voltage value leading to an over-consumption of motor current up to 10% and this will increase the motor heating. Low efficiency and need of an oversized motor is the result. As torque decreases with the square of voltage the application will be exceeding sensible to load-changes and speed sensors might be required. At start, only nominal torque is available.

■Minimum thermal losses

Danfoss frequency converters feature the unique VVC switch principle to generate motor voltages. Due to the VVC principle, power losses in the

Principle of a frequency converter using a DC link coil

The Danfoss option is to add coils to the DC link inalldrivesasshowninthefigure. Thiswaya high DC link voltage with a very low voltage ripple is obtained and the electric strength of the drive with regard to line transients is improved.

Further advantages are the prolonged lifetime of the capacitors, reduced harmonic disturbance of the net supply and presence of 150-160% start torque.

Numerous manufacturers of frequency inverters use slim DC links leading to bad efficiency rates – even if users due to the activity of for instance the CEMEP now tend to use high efficiency motors - meeting at least EFF2.

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

Danfoss’ aim is to provide high efficiency drives that

also improve the efficiency of the motors. There should be no need of expensive over-dimensioning and inefficient operation.

■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.

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.

Aseptic Danfoss geared motor

Danfoss decentralised drives are designed to meet the requirements as shown in Figure 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.

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

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 tendstocondensate. Atthesametimepressure 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.

Build-up of water inside enclosures can be prevented bymembranesthatpreventsfluidstopenetrate but allows for vapour to pass, as known from fabrics used for outdoor clothing.

■The decentralised product range

The Danfoss decentralised concept covers motor controls ranging from motor starters/soft starters to frequency converters.

Motor starters and soft starters (DMS 300) make start and stop of your application smoother and smarter than ordinary DOL (Direct On Line) operation but do not affect operation further.

Frequency converters (FCD 300) are used for following requirements:

• Adjustable speed

• Precise speed

• Defined speed ramps at start or/and stop

• Shorter stop times (braking)

Danfoss decentralised motor controls range from

0.18kWto3kW(connectstoupto4kWand

5 HP motors). This chapter lists several optional features and accessories available.

■Enclosure

DMS 300 / FCD 300 units are protected against water and dust as standard. See also the section entitled Technical data for further details.

■Brake

FCD 300 is available with or without an integral brake module. See also the section entitled Brake resistors for ordering a brake resistor. EB version including mechanical brake control/supply.

NB!:

DMS 300 always needs 24 V external control supply.

■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.

■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 I

by typically 40 %.

RMS

■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. Alldisplaysofdataareviaa4-linealpha-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 supplement 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.

■Information and communication

Growth in the world of automation is increasingly based on information technology. Having reformed hierarchies, structures and flows in the entire office world, use of information technology opens for a similar restructuring of industrial sectors ranging from process and manufacturing industries to logistics and building automation.

Devices capability of communication and continuous transparent channels for information are indispensable in automation concepts of the future.

IT is an evident means for optimisation of system processes, leading to improved exploitation of energy, materials and investment.

Industrial communication systems are a key function in this respect.

Cell level

Programmable controllers such as PLC and IPC communicate at cell level. Large data packets and numerous powerful communication functions provide information flow. Smooth integration into company-wide communication systems, such as Intranet and Internet via TCP/IP and Ethernet are important requirements.

Field level

Distributed peripherals such as I/O modules, measuring transducers, drive units, valves and operator terminals communicate with the automation systems via an efficient, real-time communication system at field level. Transmission of process data is performed in cycles, while alarms, parameters and diagnostic data have to be transmitted acyclically if necessary.

Sensor/actuator level

Binary signals from sensors and actuators are transmitted purely cyclically via bus communication.

■Profibus

Profibus is a vendor-independent, open field bus standard for use in a wide range of applications in manufacturing and process automation. Vendor-independence and openness are ensured by the international standards EN 50170, EN 50254 and IEC 61158.

Profibus communicates between devices from different manufacturers without specific interface adjustments and can be used for both high-speed time critical applications and complex communication tasks. Due to ongoing technical developments, Profibus is widely acknowledged as the leading industrial communication system of the future.

More than 2,000 products from approximately 250 Profibus vendors are available today. More than 6.5 million devices representing a huge variety of products are installed and successfully used in more than 500,000 applications in manufacturing and process automation.

Danfoss Drives solution offers a cost optimal Profibus solution

• MCT-10 software tool for access via standard PC

• Simple two-wire connection

• A universal, globally accepted product

• Compliance with the international standard

EN 50170

• Communication speed 12 Mbaud

• Access to drive master file makes planning easy

• Fulfilment of PROFIDRIVE guideline

• Integrated solution

• All frequency converters with Profibus are certified

by the Profibus organisation

• Danfoss frequency converters support

Profibus DP V1

Profibus DP V1 for two different purposes

Fieldbus systems are used for two very different purposes with two very different sets of essentials in modern automation applications. One is transfer of signals referring to the process itself, the other service, commissioning and set-up communication.

Transfer of control and status signals between sensors and actuators is time critical and must be processed reliably and in real time. This is accomplished by cyclic communication where each node in the network is polled within each cycle, and each cycle has a pre-defined time. It is necessary to pre-define and minimise the extent of data in each telegram to make this work reliably and as fast as possible.

This consideration contradicts the second use of the fieldbus, namely as a timesaving set-up and diagnostics bus. Set-up and diagnostics are not time-critical, not continuously used, and require a larger amount of data in each telegram. Furthermore, you would tend to control this information from a PC or an interface device (HMI) - and not from the master (typically a PLC) that controls the cyclic communication. Standard Profibus does not support networks with several masters so set-up and diagnostics information must be contained in the standard telegram handled by the master, making for very long and time consuming telegrams with room for information only sporadically used.

Profibus DP V1 now combines the two sets of requirements from above in a single fieldbus system,

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

allowing a second master to use the entire network in a specified time slot in each cycle. Profibus DP V1 thus operates with two classes of masters. Masterclass 1 (typically a PLC) performs the cyclic communication. Masterclass 2, typically an interface device (HMI or PC), transfers non-time critical information through non-cyclic communication.

Masterclass 2 masters can be connected anywhere on the Profibus net and the communication channel can be opened and closed anytime without disturbing the cyclic communication. You can have non-cyclic communication even without cyclic communication to for instance transfer complete programs or set-ups.

Profibus DP V1 is fully compatible with prior versions of Profibus DP V0. Profibus DP V0 and Profibus DP V1 nodes can be combined in the same network, although the master must support Masterclass 2 communication.

User benefits:

• Connection to the motor controls is possible

from every part of the network

• Existing network can be used for commissioning,

set-up and diagnostic without disturbing of the cyclic communication

• Both DP V1 and DP V0-nodes can be

connected in the same network

• No need for extensive telegrams in the PLC

or IPC. A second master who supports DP V1 can handle set-up tasks

NB!:

DP V1 is only possible for Master communication-cards which support Masterclass 2 specification.

■DeviceNet

DeviceNet is a communications link that connects industrial devices to a network. It is based on the broadcast-oriented, communications protocol CAN (Controller Area Network).

The CAN protocol was originally developed for the European automotive market to be used in exchange for expensive wire harnesses in automobiles. As a result, the CAN protocol offers fast response and high reliability for demanding applications like ABS brakes and air bags.

• Acyclic communication – "explicit messaging"

• Unconnected Messages Manager (UCMM)

messages are supported

• Integrated solution

• Electronic Data sheet (EDS)-files secures

easy configuring

• Provides fieldbus voltage supply

• Fulfilment of DeviceNet AC/DC motor profile

• Protocol defined in accordance with the Open

DeviceNet Vendor Association (ODVA)

■AS-interface

AS-interface (AS-i) is a cost-efficient alternative to conventional cabling at the lowest level of the automation hierarchy. The network can link into a higher-level fieldbus like Profibus for low-cost remote I/O. Known by its yellow cable; AS-I has grown an "open" technology supported by more than 100 vendors worldwide. Enhancements through time have broadened its field of applications and AS-interface is today proven in hundreds of thousands of products and applications spanning the automation spectrum.

■InterBus

InterBus is an open, non-proprietary standard. It complies with the EN 50254 standard. Using decentralised motor controls with integrated fieldbus communication allows you to connect to an InterBus network.

• Easy connection

• Compliance with the international standard

EN 50254

• I/O based transmission principle, high

protocol efficiency

• Unified planning tool (e.g. CMD software)

• InterBus option is certified by the

Frauenhofer Institute

The Gateway IB-S/DP for Danfoss frequency converters allows for up to 14 frequency converters of different series on the same InterBus network.

■FC Protocol

An RS-485 interface is standard on all Danfoss frequency converters allowing for up to 126 units in one network. The FC protocol has a very simple design described in Serial Communication.For applications where data transmission speed is of less importance, the RS 485 interface provides a good alternative to the faster fieldbus solution.

■Good Installation Pr actice

■Flexible installation options

A major benefit of Danfoss’ decentralised concept

is saving installation cost partly due to the clever two-part design of the DMS 300/FCD 300.

All electrical installation is done inside the installation box prior to mounting the electronic part. Subsequently the electronic part is plugged into the installation box, fixed, and the drive is ready for operation.

Power line looping

The FCD 300 and DMS 300 series facilitates internal

power line looping. Terminals for 4 mm

power cables

inside the enclosure allows connection of up to 10+

units. FCD 300 and DMS 300 can be mixed along the line. Average load must not exceed 25 A.

24 V control back up

External 24 V (20-30 V) DC can be connected in the EX and EB versions for back-up of control circuits. This way communication and programming possibility are maintained even during power down. The terminals are dimensioned for up to 2.5 mm

and are doubled for looping (FCD 300). DMS 300 always needs 24 V external supply.

The T63 and T73 installation boxes have additional

loopingterminalsfor2X24Vwith4mm

. Connected sensors can be supplied separately from the control back up supply.

■Guidelines for selection of cables and fuses in a

powerline installation with FCD and DMS products

It is assumed that the installation follows the Low Voltage Directive as stated in HD 384 and IEC 60364.

This section can’tbeusedinexplosiveareasand

where fire hazard exists. In general cable dimension has to follow IEC 60364-5-523. If the installation is part of a machinery EN 60204-1 has to be followed. Cables as mentioned under point 1, 2 and 3 in the figure has to be protected by an enclosure or conduit. The following section numbers refer to the figure.

1. The cable shall only be able to carry the maximum continuous current of the friction brake. By ground fault non-renewable protective circuit in the FCD will interrupt the flow of current.

2. If the IP 65 brake resistors recommended by Danfoss are used the cable will only be exposed to the continuous current of the brake resistor. If the brake resistor becomes overheated it will disconnect itself. If another type or make of brake resistor, without any power limitation device, is used, the maximum power must be equal to the rated power of the motor. The current in Amps would be: I = 0.77/motor power, with motor power inserted in kW; [A=V/W]. The rated motor current comes fairly close to the current in the cable to the brake resistor.

3. The cables to encoders and thermistors are on PELV potential. The currents are in mA range and limited by the FCD or DMS. In order not

to violate the PELV protection of the control terminals of FCD the thermistor has to have reinforced insulation according to the PELV demands. For EMI purposes the cables must have their own electrical shielding and if possible be kept separated from power cables.

4. The cable is protected by the current limit function in the FCD. By ground faults and short circuit of low impedance the FCD will interrupt the current.

5. The current is limited by the DMS*, and ground and short circuit protected by the circuit breaker (CB).

6. The current is limited by the downstream FCD and DMS*. The CB makes the ground and short circuit protection. The impedance in the leads has to be so low that the CB disconnects in 5 s by low impedance ground faults. (TN supply).

7. If installation is on a machine (EN 60204-1) and the distance between the T connection and the FCD or DMS* is less than 3 m, the cable can be downsized to the current capacity that is needed for the down stream FCD.

8. The trip current for the CB upstream must not be higher than the highest maximal prefuses for the smallest FCD or DMS downstream.

See section Fuses for DMS coordination class.

For EMC purposes cable # 2, 3 & 4 has to be shielded or placed in metal conduits.

■Service

Breakdown of Danfoss drives or geared motors only occur under exceptional circumstances. As downtime represents lack of production, failures must be located and defective components replaced quickly.

Danfoss’ decentralised products place great

emphasis on addressing these issues. This chapter also describes measures taken to make Danfoss decentralised products superior in a service situation. For detailed information on specific service issues please consult relevant literature.

Centralised frequency converters from Danfoss have pluggable connections to facilitate service using fast and faultless replacement. The same concept is used and improved for the decentralised drives.

Plug-and-drive

All the advanced and reliable electronics needed to ensure your motors act smoothly, responsively and economically at each command are hidden inside the box lid and plug into connectors when mounted onto the bottom section. The bottom section contains maintenance-free Cage Clamp connectors and looping facilities for power and fieldbus cables well protected against dust, hosing and cleaning agents. Once installed, commissioning and upgrading can be performed in no time simply by plugging in another control lid. See the illustration.

You only need standard installation material like cable glands, cables, etc., to commission and service a Danfoss decentralised drive. Special equipment like hybrid cables not likely to be held in stock by a standard supplier of electric installation components is needed. This provides high flexibility and maximum uptime.

Product concept

Since the installation box only contains plugs,

connectors and low density pcb’s, it is not likely

to fail. In case of a failure in the electronic part, just remove the six screws, unplug the electronic part and plug in a new one.

Decentral Solutions - Design Guide

■Safety regulations

1. The DMS must be disconnected from the mains if repair work is to be carried out.

2. The [COASTING STOP INVERSE] command applied to the DMS does not disconnect the equipment from the mains and thus is not to be used as a safety switch.

It is the responsibility of the user or the person installing the DMS to provide proper grounding and branch circuit protection in

accordance with national and local regulations.

■Warning against unintended start

1. The motor can be brought to a stop by means of digital commands, bus commands or a local stop, while the DMS is connected to the mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, stop functions are not sufficient .

2. A motor that has been stopped may start if faults occur in the electronics of the DMS.

■General warning

The DMS contains dangerous voltages when connected to line voltage. Only a

competent electrician should carry out the electrical installation. Improper installation of the motor or the DMS may cause equipment failure, serious injury or death. Follow this manual as well as national and local rules and safety regulations.

■Avoiding DMS damage

Please read and follow all instructions in this manual.

Electrostatic Precaution; Electrostatic discharge (ESD). Many electronic

■Ventilation

DMS cooling is by means of air circulation. Consequently, the air needs to be able to move freely above and below the soft starter. If installing the DMS in a switchboard or other enclosure, ensure there is sufficient airflow through the enclosure to limit heat rise in the enclosure to maintain the internal enclosure temperature at or below 40 deg. C. (Heat loss of DMS at rated current is 18 watts approx.).

Decentral Solutions - Design Guide

Use cables complying with local regulations.

■Motor thermistors

If the motor is fitted with thermistors these may be connected directly to the DMS. To connect the thermistors, first remove the shorting link, and then connect the thermistors between terminals 31A & 31B.

Use double-isolated thermistors to retain PELV.

■Serial communication

The DMS can be equipped with either AS-i or Profibus communication capabilities. The AS-i and Profibus interfaces are optional. The AS-i Fieldbus is connected at terminals 125 & 126. The details of the Profibus connectivity are given at the end of the manual.

NB!:

Communications and control cabling should not be located within 300mm of power

cabling. Where this cannot be avoided consideration should be given to providing magnetic shielding to reduce induced common mode voltages, for example, by laying the communication and control cables in a separate conduit.

■Galvanic isolation (PELV)

All control terminals, and terminals for serial communication are safely isolated from

the mains potential, i.e. they comply with the PELV requirements of EN/ IEC 60947-1. PELV isolation of the control card is guaranteed provided there is max. 300 VAC between phase and earth.

■Earthing

Ensure that the DMS unit is earthed properly. Use the chassis earth studs provided for the purpose (4 of size M4). For type T73 units, an external earth plug

(size M8) is provided to facilitate earthing.

To retain the IP rating of DMS, remember to close all the unutilized cable entries

using the gland plugs (bungs) provided loose with the DMS unit. In units with external plugs, all plugs must be correctly mounted.

■High voltage warning

The voltage of the DMS is dangerous

whenever the equipment is connected to

the mains. Ensure the DMS is correctly connected and that all safety measures have been taken before switching on the supply.

■Trip Class selection:

This setting is applicable only for the Extended versions of DMS. The DMS motor overload protection is an advanced motor thermal model. Motor temperature is continuously calculated by the microprocessor. This uses a sophisticated mathematical model to accurately reflect motor heat generation and dissipation during all stages of operation, e.g. Starting, Running, Stopping & Stopped. Because it operates continuously, the motor thermal model eliminates the need for protection systems such as Excess Start Time, Limited Starts per hour etc. Calibrate the DMS motor thermal model for theTrip Class of the connected motor. The Motor Trip Class is defined as the length of time the motor can sustain Locked Rotor Current. The motor Trip Class can be found from the motor curves or data sheet. For example, if a given motor can

# In some applications, actual ramp time on the motor shaft could differ from the settings.

withstand Locked Rotor Current for 10 sec, set Trip Class 10 (or lower) in the DMS. If in doubt, use "Trip Class 5", which is the Factory Default setting for this parameter. With this setting, the DMS will trip & protect the motor if the Locked Rotor current sustains for more than 5 secs. Use the DIP switches A5-A6 to choose the Trip Class.

■Operation

Once the DMS has been installed, wired and programmed according to the instructions, it can be operated.

Decentral Solutions - Design Guide

■Operation with AS-i Interface

The AS-i switch profile S-7.E is used, having the following inputs and outputs:

■Powering-up the DMS

Power may now be applied to the DMS unit. The "On" LED should glow when the 24VCD Control Supply is turned On.

■Starting the motor:

Connect +24VDC to the "Reset/ Coasting stop inverse input (27). To start the motor in the Forward direction, use the Start CW Input (18). To initiate a stop, open the Start CW Input.

To start the motor in the Reverse direction, use the Start CCW Input (19).This feature is optional. To initiate a stop, open the Start CCW Input.

If the direction of rotation is wrong, change any two of mains or motor phases.

Disconnecting the +24VDC to the "Reset/ Coasting stop inverse input (27) will disable the DMS and cause the motor to coast to stop.

NB!:

If both Start CW & Start CCW inputs are active together, the motor will stop.

■Brake Release

(For variants with Braking function only variants SB, EB, ER). When a Start is initiated, the DMS automatically generates a brake release command. This will release the brakes before the motor starts running. The motor brake can also be released without starting the motor by connecting +24VDC to the Brake Release input (124).

NB!:

Mains supply to the DMS is required for the operation of Brake Release. The Electromechanical brake supply is

not short-circuit protected.

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

■High voltage warning

The voltage of the frequency converter is dangerous whenever the converter

is connected to mains. Incorrect fitting of the motor or frequency converter may cause damage to the equipment, serious injury or death. Consequently, it is essential to comply with the instructions in this manual as well as local and national rules and safety regulations.

■These rules concern your safety

1. The frequency converter must be disconnected from

the mains if repair work is to be carried out. Check that the mains supply has been disconnected and that the prescribed time has passed before removing the inverter part from the installation.

2. The [STOP/RESET] key on the optional control

panel does not disconnect the equipment from mains and is thus not to be used as a safety switch.

3. The unit must be properly connected to the

earth, the user must be protected against the supply voltage and the motor must be protected against overloading pursuant to prevailing national and local regulations.

4. The earth leakage currents are higher than 3.5 mA.

5. Protection against motor overload is not included

in the factory setting. If this function is required,

set parameter 128 Motor thermal protection to data value ETR trip or data value ETR warning.For the North American market: The ETR functions provide overload protection of the motor, class 20, in accordance with NEC.

■Warning against unintended start

1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.

2. While parameters are being changed, the motor may start. Consequently, the stop key [STOP/RESET] on the optional control panel must always be activated, following which data can be modified.

3. A motor that has been stopped may start if faults occur in the electronics of the frequency converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.

Warning:

It can be extremely dangerous to touch the electrical parts even when the AC line supply has been disconnected.

For FCD 300: wait at least 4 minutes.

Introduction to FCD

MG.90.F3.02 - VLT is a registered Danfoss trademark

■Technology

■Control principle

A frequency converter rectifies AC voltage from the mains supply into DC voltage, following which it changes this voltage to an AC voltage with variable amplitude and frequency. The motor thus receives a variable voltage and frequency, which enables infinitely variable speed control of three-phase, standard AC motors.

1. Mains voltage 3 x 380 - 480 V AC, 50 / 60 Hz.

. Rectifier Three-phase rectifier bridge which rectifies AC voltage into DC voltage.

Decentral Solutions - Design Guide

■The decentral concept

The FCD 300 Adjustable speed drive is designed for decentral mounting, e.g. in the food and beverage industry, in the automotive industry, or for other material handling applications.

With the FCD 300 it is possible to utilize the cost saving potential by placing the power electronics decentrally, and thus make the central panels obsolete saving cost, space and effort for installation and wiring.

The unit is flexible in its mounting options for as well stand alone mounting and motor mounting. It is also possible to have the unit pre-mounted on a Danfoss Bauer geared motor (3 in one solution). The basic design with a plugable electronic part and a flexible and "spacious" wiring box is extremely servicefriendly and easy to change electronics without the need for unwiring.

The FCD 300 is a part of the VLT frequency converter family, which means similar funcionality, programming, and operating as the other family members.

. Intermediate circuit

DC voltage √2 x mains voltage [V].

. Intermediate circuit coils Evens out the intermediate circuit current and limits the load on mains and components (mains transformer, cables, fuses and contactors).

. Intermediate circuit capacitor

5 Evens out the intermediate circuit voltage.

. Inverter Converts DC voltage into a variable AC voltage withavariablefrequency.

. Motor voltage

7 Variable AC voltage depending on supply voltage. Variable frequency: 0.2 - 132 / 1 - 1000 Hz.

. Control card

8 Here is the computer that controls the inverter which generates the pulse pattern by which the DC voltage is converted into variable AC voltage with a variable frequency.

■FCD 300 control principle

A frequency converter is an electronic unit which is able to infinitely variably control the rpm of an AC motor. The frequency converter governs the motor speed by converting the regular voltage and frequency from mains, e.g. 400 V / 50 Hz, into variable magnitudes. Today the frequency converter controlled AC motor is a natural part of all types of automated plants. The FCD 300 Series has an inverter control system called VVC (Voltage Vector Control). VVC controls an induction motor by energizing with a variable frequency and a voltage suitable for it. If the motor load changes, so does its energizing and speed. That is why the motor current is measured on an ongoing basis, and a motor model is used to calculate the actual voltage requirement and slip of the motor.

■Programmable inputs and outputs in four Setups

In the FCD 300 Series it is possible to program the different control inputs and signal outputs and to select four different user-defined Setups for most parameters. It is easy for the user to program the required functions on the control panel or via serial communication.

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

■Mains protection

The FCD 300 Series is protected against the transients that may occur on the mains, such as coupling with a phase compensation system or transients from fuses blown or when lightening strikes.

Rated motor voltage and full torque can be maintained down to approx. 10% undervoltage in the mains supply.

As all 400 V units in the FCD 300 Series have intermediate circuit coils, there is only a low amount of harmonic mains supply interference. This gives a good power factor (lower peak current), which reduces the load on the mains installation.

■Frequency converter p rotection

The current measurement in the intermediate circuit constitutes perfect protection of the FCD 300 Series in case there is a short-circuit or an earth fault on the motor connection. Constant monitoring of the intermediate circuit current allows switching on the motor output, e.g. by means of a contactor. Efficient monitoring of the mains supply means that theunitwillstopinthecaseofaphasedrop-out(if the load exceeds approx. 50%). In this way, the inverter and the capacitors in the intermediate circuit are not overloaded, which would dramatically reduce the service life of the frequency converter. The FCD 300 Series offers temperature protection as standard. If there is a thermal overload, this function cuts out the inverter.

at low frequencies because of reduced fan speed (motors with internal fan). This function cannot protect the individual motors when motors are connected in parallel. Thermal motor protection can be compared to a protective motor switch, CTI. To give the motor maximum protection against overheating when it is covered or blocked, or if the fan should fail, you can install a thermistor and connect it

to the frequency converter’s thermistor input (Digital

input), see parameter 128 Thermal motor protection.

NB!:

This function cannot protect the individual motors in the case of motors linked in parallel.

Introduction to FCD

■Reliable galvanic isolation

In the FCD 300 all digital inputs/outputs, analogue inputs/outputs and the terminals for serial communication are supplied from or in connection with circuits that comply with PELV requirements. PELV is also complied with in relation to relay terminals at max. 250 V, so that they can be connected to the mains potential. See section Galvanic Isolation (PELV) for further details.

■Advanced motor protection

The FCD 300 Series has integral electronic motor protection. The frequency converter calculates the motor temperature on the basis of current, frequency and time. As opposed to traditional, bimetallic protection, electronic protection takes account of reduced cooling

■CE labelling

What is CE labelling?

The purpose of CE labelling is to avoid technical obstacles to trade within EFTA and the EU. The EU has introduced the CE label as a simple way of showing whether a product complies with the relevant EU directives. The CE label says nothing about the specifications or quality of the product. Frequency converters are regulated by three EU directives:

The machinery directive (98/37/EEC)

All machines with critical moving parts are covered by the machinery directive, which came into force on 1 January 1995. Since a frequency converter is largely electrical, it does not fall under the machinery directive. However, if a frequency converter is supplied for use in a machine, we provide information on safety aspects relating to the frequency converter. We do

this by means of a manufacturer’sdeclaration.

The low-voltage directive (73/23/EEC)

Frequency converters must be CE labelled in accordance with the low-voltage directive, which came into force on 1 January 1997. The directive applies to all electrical equipment and appliances used in the 50 - 1000 Volt AC and the 75 1500 Volt DC voltage ranges. Danfoss CE labels in accordance with the directive and issues a declaration of conformity upon request.

The EMC directive (89/336/EEC)

EMC is short for electromagnetic compatibility. The presence of electromagnetic compatibility means that the mutual interference between different components/appliances is so small that the functioning of the appliances is not affected. The EMC directive came into force on 1 January 1996. Danfoss CE labels in accordance with the directive and issues a declaration of conformity upon request. In order that EMC-correct installation can be carried out, this manual gives detailed instructions for installation. In addition, we specify the standards which our different products comply with. We offer the filters that can be seen from the specifications and provide other types of assistance to ensure the optimum EMC result.

In the great majority of cases, the frequency converter is used by professionals of the trade as a complex component forming part of a larger appliance, system or installation. It must be noted that the responsibility for the final EMC properties of the appliance, system or installation rests with the installer.

Decentral Solutions - Design Guide

■ATEX

What is ATEX?

Directive 94/9/EC is valid in the European Union (EU) with the purpose of creating unified standards for equipment and protective systems intended for use in potentially explosive atmospheres. The directive was valid from July 2003, and all equipment installed and built into potentially explosive areas in EU after this date, must comply with this directive. The directive and its derivatives are often referred to as the ATEX-directive. ATEX is an acronym for ATmosphere Explosible.

It has been found practical to classify hazardous areas into zones according to the likelihood of an explosivegas/dustatmospherebeingpresent(seeIEC 79-10). Such classification allows appropriate types of protection to be specified for each zone.

Motors supplied at variable frequency and voltage

When electrical motors are to be installed in areas where dangerous concentrations and quantities of flammable gases, vapours, mists, ignitable fibres or dusts may be present in the atmosphere, protective measures are applied to reduce the likelihood of explosion due to ignition by arcs, sparks or hot surfaces, produced either in normal operation or under specified fault conditions.

Motors supplied at varying frequency and voltage require either:

• Means (or equipment) for direct temperature control

by embedded temperature sensors specified in the motor documentation or other effective measures for limiting the surface temperature of the motor housing. The action of the protective device shall be to cause the motor to be disconnected. The motor and frequency converter combination does not need to be tested together, or

• The motor must have been type-tested for this duty

as a unit in association with the frequency converter specified in the descriptive documents according to IEC 79-0 and with the protective device provided.

FCD 300 and ATEX

The following variants of the FCD 300 can be installed directly in Group II, Category 3, and Zone 22 areas:

Decentral FCD3xx-P-T4-P66-xx-R1-

Decentral FCD3xx-P-T4-P66-xx-R1-

VLT Dx-Fxx-T52-Cx

MG.90.F3.02 - VLT is a registered Danfoss trademark

Decentral Solutions - Design Guide

Group II, Category 3, and Zone 22 areas are characterised by:

• Surface installations

• Explosive atmosphere is unlikely to occur or,

if it does, is likely to only be of short duration and not in normal duty

• The explosive media is dust

ThemaximumsurfacetemperatureoftheFCD 300 during worst-case normal duty is limited to 135°C. This temperature must be lower than the ignition temperature of the present dust.

The installer must define the zone, category and dust ignition temperature of the environment where the FCD 300 is installed.

ATEX correct installation

The following issues must be taken into account when installing the FCD 300 in ATEX zone 22 environments:

• Motor must be designed, tested and certified by the

motor manufacturer for variable speed application

• Motor must be designed for Zone 22 operation.

I.e. with type of protection "tD" acc. to EN61241-0 and -1 or EN50281-1-1.

• Motor must be provided with thermistor protection.

The thermistor protection must either be connected to an external thermistor relay, with EC Type Examination Certificate or compatible with the FCD 300 thermistor input. If the FCD 300 thermistor protection is used, the thermistor must be wired to terminals 31a and 31b, and thermistor trip activated by programming parameter 128 to thermistor trip [2]. See parameter 128 for further details.

• Cable entries must be chosen for the enclosure

protection to be maintained. It must also be ensured that the cable entries comply with the requirements for clamping force and mechanical strengths as described in EN 50014:2000.

• The FCD must be installed with appropriate earth

connecting according to local/national regulations.

• The installation, inspection and maintenance of

electrical apparatus for use in combustible dusts, must only be carried out by personnel that is trained and familiar with the concept of protection.

■Mechanical installation

Please pay attention to the requirements that apply to integration and remote

mounting. These must be complied with to avoid serious injury or damage, especially when installing large units.

The FCD 300 consists of two parts: The installation part and the electronics part. The two parts must be separated, and the installation part is to be mounted first. After wiring, the electronics is to be fixed to the installation part by the attached 6 screws. For compressing the gasket the screws must be tightened with 2-2.4 Nm, tighten both centre screws first, thereafter the 4 corner srews "cross over".

NB!:

Do not switch on the mains before the 6 screws are tightened.

The FCD 300 can be applied as following:

- Stand alone mounted close to the motor

- Motor mounted

or might be delivered pre mounted on a Danfoss Bauer (geared) motor. Please contact the Danfoss Bauer sales organisation for further information.

The frequency converter is cooled by means of air circulation. For the unit to be able to release its cooling air, the minimum free distance above and below the unit must be m the unit from overheating, it must be ensured that the ambient temperature does not rise above the max. temperature stated for the frequency converter and that the 24-hour average temperature is not exceeded. The max. temperature and 24-hour average can be seen in General technical data. If the ambient temperature is higher, derating of the frequency converter is to be carried out. See Derating for ambient temperature.Pleasenotethattheservicelife of the frequency converter will be reduced if derating for ambient temperature is not considered.

otor mounting

M The installation box should be mounted on the surface of the motor frame, typically instead of the motor terminal box. The motor/geared motor may be mounted with the shaft vertically or horizontally. The unit mustnot be mounted upside down (the heat sink pointing down). The cooling of the electronics is independent on the motor cooling fan. For mounting directly on Danfoss Bauer geared motors no adaption plate is necessary. For motor mounting (non Danfoss Bauer motors), an adaptor plate should usually be applied. For that purpose a neutral plate incl gasket and screws for attaching to the installation box is available. The appropriate drillings and gasket for the motor housing are applied locally. Please make sure, that the mechanical strength of the mounting screws and the threads are sufficient for the application. The specified resistance against mechanical vibrations does not cover the mounting onto a non Danfoss Bauer motor, as the stability of the motor frame

and threads are outside Danfoss Drive’s control and

responsibility and the same applies to the enclosure class. Please be aware, that the frequency converter may not be used to lift the motor/geared motor.

■General information about electrical installation

■High voltage warning

The voltage of the frequency converter

is dangerous whenever the equipment is

connected to mains. Incorrect installation of the motor or frequency converter may cause damage to the equipment, serious injury or death. Comply with the instructions in this manual, as well as national and local rules and safety regulations. Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains: Wait at least 4 minutes for current dissipate.

NB!:

It is the responsibility of the user or installer to ensure correct earthing and protection in accordance with national and local standards.

■Cables

The control cable and the mains cable should be installed separately from motor cables to prevent noisetransfer. Asaruleadistanceof20cmis sufficient, but it is recommended that the distance is as great as possible, particularly when cables are installed in parallel over large distances.

For sensitive signal cables such as telephone or data cables the greatest possible distance is recommended. Please note that the required distance depends on installation and the sensitivity of the signal cables, and that for this reason exact values cannot be given.

■Extra p rotection

ELCB relays, multiple protective earthing or earthing can be used as extra protection, provided that local safety regulations are complied with. In the case of an earth fault, a DC content may develop in the faulty current. Never use an RCD (ELCB relay), type A, as it is not suitable for DC faulty currents. If ELCB relays are used, local regulations must be complied with. If ELCB relays are used, they must be:

- Suitable for protecting equipment with a DC content in the faulty current (3-phase bridge rectifier)

- Suitable for a pulse-shaped, brief discharge on power-up

- Suitable for a high leakage current.

See also RCD Application Note MN.90.GX.02.

■High voltage test

A high voltage test can be performed by short-circuitingterminalsU,V,W,L1,L2andL3, and applying max. 2160 V DC in 1 sec. between this short-circuit and PE-terminal.

■Electronics purchased without installation box

If the electronic part is purchased without the Danfoss installation part, the earth connection

the

must be suitable for high leakage current. Use of original Danfoss installation box or installation kit 175N2207 is recommended.

When being placed in cable trays, sensitive cables may not be placed in the same cable tray as t motor cable. If signal cables run across power cables, this is done at an angle of 90 degrees. Remember that all noise-filled inlet to a cabinet must be screened/armoured. See also EMC-compliant electrical installation.

Cable glands

It must be assured that appropriat glands needed for the environment are chosen and carefully mounted.

■Screened/armoured cables

The screen must have low HF impe achieved by a braided screen of copper, aluminium or iron. Screen reinforcement intended for mechanical protection, for example, is installation. See also Use of EMC-correct cables.

■Protective ear th

The earth connection serves several purposes.

• Safety earth (Protective earth, PE)

The equipment must be properly earthed according to local regulation. This equipment has a leakage current > 3.5 mA AC. It must be connected to an earth connection complying with the local rules for high leakage current equipment. Typically, this implies that the PE conductors must be mechanically enhanced (minimum cross

section 10 mm

) or duplicated

• Noise "clamping" (high frequencies)

Stable communication between units call for screening of the communication cables (1).

Cables must be properly attached to screen clamps provided for that purpose.

• Equalisation of voltage potential (low frequencies) To reduce alignment currents in the screen of the communication cable, always apply a short earthing cable between units that are connected to the same communication cable (2) or connect to an earthed frame (3).

• Potential equalization: All metal parts, where the motors are fastened, must be potential equalized

PE connections, voltage equalising cables and the screen of the communication cable should be connected to the same potential (4).

Keep the conductor as short as possible and use the greatest possible surface area.

The numbering refers to the figure.

■EMC-correct elec

trical installation

General points to be observed to ensure EMC-correct electrical installation.

- Use only screened/armoured motor cables and screened/armou

red control cables.

- Connect the screen to earth at both ends.

- Avoid installati

on with twisted screen ends (pigtails), since this ruins the screening effect at high frequencies. Use cable clamps instead.

■Use of EMC compliant cables

In order to comply with requirements for EMC immunity of the control cables and EMC emissions from the motor cables screened/armoured cables must be used. The ability of a cable to reduce the amount of ingoing and outgoing radiation of electric noise depends on the transfer impedance (Z

). The screen of a

cable is normally designed to reduce the transfer of electric noise, and a screen with a lower Z effective than a screen with a higher Z

is rarely stated by cable manufacturers, but it

is often possible to estimate Z

by looking at and

assessing the physical design of the cable.

can be assessed on the basis of the following factors:

- the contact resistance between the individual screen conductors.

- Screen coverage, i.e. the physical area of the cable covered by the screen. Is often stated as a percentage and should be no less than 85%.

- The screen type, i.e. braided or twisted pattern. A braided pattern or closed pipe is recommended.

■Earthing of screened/armoured control cables

In general control cables must be screened/armoured,

and the screen must be connected to the unit’s metal

cabinet with a cable clamp at each end.

The drawing below shows the correct way to perform the earthing, and what to do when in doubt.

1. Correct earthing

Control cables and cables for serial communication must be attached with cable clamps at both ends to ensure maximum possible electrical contact.

2. Incorrect earthing

Do not use twisted screen ends that are plaited together (pigtails), as these increase screen impedance at higher frequencies.

3. Protection with respect to earth

potential between PLC and VLT

If the earth potential between the VLT frequency converter and the PLC (etc.) is different, electric noise may occur that will disturb the whole system. This problem can be solved by fitting an equalising cable, to be placed next to the control cable. Minimum cable cross-section: 16 mm

4. In the event of a 50/60 Hz earth loop

If very long control cables are used, 50/60 Hz earth loops can arise, and these can interfere with the whole system. This problem is resolved by attaching one end of the screen to the earth via a 100 nF capacitor (short pin length).

■Parallel connection of motors

The frequency converter is able to control several motors connected in parallel. If the motors are to have different rpm values, use motors with different rated rpm values. Motor rpm is changed simultaneously, which means that the ratio between the rated rpm values is maintained across the range. The total current consumption of the motors is not to exceed the maximum rated output current

for the frequency converter.

INV

Problems may arise at the start and at low rpm values if the motor sizes are widely different. This

is because the small motors’ relatively high ohmic

resistance in the stator calls for a higher voltage at the start and at low rpm values.

converter cannot be used as motor protection for the individual motor. For this reason further motor protection must be used, e.g. thermistors in each motor (or an individual thermal relay).

NB!:

Parameter 107 Automatic motor tuning, AMT cannot be used when motors are connected

in parallel. Parameter 101 Torque characteristic must be set to Special motor characteristics [8] when motors are connected in parallel.

■Motor cables

See Technical data for correct dimensioning of motor cable cross-section and length. Always comply with national and local regulations on cable cross-section.

NB!:

If an unscreened/unarmoured cable is used,

some EMC requirements are not complied with,

see EMC test results in the Design Guide.

If the EMC specifications regarding emission are to be complied with, the motor cable must be screened/armoured, unless otherwise stated for the RFI filter in question. It is important to keep the motor cable as short as possible so as to reduce the noise level and leakage currents to a minimum. The motor cable screen must be connected to the metal cabinet of the frequency converter and to the metal cabinet of the motor. The screen connections are to be made with the biggest possible surface area (cable clamp). This is enabled by different installation devices in different frequency converters. Mounting with twisted screen ends (pigtails) is to be avoided, since these spoil the screening effect at high frequencies. If it is necessary to break the screen to install a motor isolator or motor relay, the screen must be continued at the lowest possible HF impedance.

In lifting/lowering applications you need to be able to control an electromagnetic brake. The brake is controlled using the special mechanical brake control/supply terminals 122/123. When the output frequency exceeds the brake cut out value set in par. 138, the brake is released if the motor current exceeds the preset value in parameter

140. When stopping the brake is engaged when the output frequency is less than the brake engaging frequency, which is set in par. 139. If the frequency converter is at alarm status or in an overvoltage situation the mechanical brake is cut in immediately. If not using the special mechanical brake control/supply terminals (122-123), select Mechanical brake control in parameter 323 or 341 for applications with an electromagnetic brake. A relay output or digital output (terminal 46) can be used. See Connection of mechanical brake for further details.

■Electrical installation, control cables

Control cables must be screened/armoured. The screen must be connected to the frequency converter chassis by means of a clamp. Normally, the screen must also be connected to the chassis of the controlling unit (use the instructions for the unit in question). In connection with very long control cables

and analogue signals, in rare cases depending on the installation, 50/60 Hz earth loops may occur because of noise transmitted from mains supply cables. In this connection, it may be necessary to break the screen and possibly insert a 100 nF capacitor between the screen and the chassis.

■Parameter Setup

A frequency converter’s comprehensive work area can

be accessed via a large number of parameters, making it possible to adapt its functionality for a specific application. To provide a better overview of the many parameters, there is a choice of two programming modes - Menu mode and Quick Menu mode. The former provides access to all parameters. The latter takes the user through the parameters, which make it possible to start operating the frequency converter in most cases, in accordance with the Setup made. Regardless of the mode of programming, a change of a parameter will take effect and be visible both in the Menu mode and in the Quick menu mode.

Structure for Quick menu mode v Menu mode

In addition to having a name, each parameter is linked up with a number which is the same regardless of the programming mode. In Menu mode, paramet will be split into groups, with the first digit (left) of the parameter number indicating the group number of the parameter in question.

107 Automatic motor tuning, AMT

(AUTO MOTOR TUN.)

Value:

✭Optimisation off (AMT OFF)

Optimisation on (AMT START)

Function:

Automatic motor tuning is an algorithm that measures stator resistance R

without the motor axle turning.

This means that the motor is not delivering any torque. AMT can be used with benefit when initialising units where the user wishes to optimise adjustment of the frequency converter to the motor being used. This is used in particular when the factory setting does not sufficiently cover the motor.

For the best possible tuning of the frequency converter it is recommended that AMT is performed on a cold motor. It should be noted that repeated AMT runs can cause heating of the motor, resulting in an increase in the stator resistance R

.Asa

rule, however, this is not critical.

AMT is performed as follows:

tart AMT:

1. Give a STOP signal.

2. Parameter 107 Automatic motor tuning is se t at value [2] Optimisation on.

3. A START signal is given and parameter 107 Automatic motor tuning is reset to [0] when AMT has been completed.

In factory setting START requires terminals 18 and 27 to be connected to terminal 12.

omplete AMT:

C AMT is completed by giving a RESET signal. Parameter 108 Stator resistance, Rs is updated with the optimised value.

nterrupting AMT:

I AMT can be interrupted during the optimisation procedure by giving a STOP signal.

When using the AMT function the following points should be observed:

- For AMT to be able to define the motor paramete as well as possible, the correct type plate data for

[0] [2]

the motor connected to the frequency converter must be keyed into parameters 102 to 106.

- Alarms will appear in the display if faults arise during tuning of the motor.

- As a rule the AMT function will be able to measure

values for motors that are 1-2 times larger or

the R

smaller than the frequency converter’snominalsize.

- If you wish to interrupt automatic motor tuning, press the [STOP/RESET] key.

NB!:

AMT may not be performed on motors connected in parallel, nor may setup changes be made while AMT is running.

Description of choice:

Select Optimisation on [2] if you want the frequency converter to perform automatic motor tuning.

Choose Start frequency/voltage clockwise [3] to obtain the function described in parameter 130 Start frequency and 131 Voltage at start during start delay time. Regardless of the value assumed by the reference signal, the output frequency equals the setting in parameter 130 Start frequency and the output voltage will correspond to the setting in parameter 131 Voltage at start . This functionality is typically used in hoist applications. It is used in particular in applications in which a cone anchor motor is applied, where the direction of rotation is to start clockwise followed by the reference direction.

Select Start frequency/voltage in reference direction [4] to obtain the function described in parameter 130 Start frequency and 131 Voltage at start during the start delay time. The direction of rotation of the motor will always follow in the reference direction. If the reference signal equals zero, the output frequency will equal 0 Hz, while the output voltage will correspond to the setting in parameter 131 Voltageatstart. If the reference signal is different from zero, the output frequency will equal parameter 130 Start frequency and the output voltage will equal parameter 131 Voltage at start.This functionality is used typically for hoist applications with counterweight.

Description of choice:

Set the required output frequency.

NB!:

If parameter 123 is set higher than parameter 130, then the start delay function (parameter 120 and 121) will be skipped.

NB!:

If parameter 123 is set too high, and DC hold has been chosen in parameter 122,

the output frequency will jump to the value in parameter 123 without ramping up. This may cause an overcurrent warning / alarm.

■DC Braking

During DC braking DC voltage is supplied to the motor, and this will cause the shaft to be brought to a standstill. In parameter 132 DC brake voltage DC brake voltage can be preset from 0-100%. Max. DC brake voltage depends on the motor data selected. In parameter 126 DC b raking time DC braking time is determined and in parameter 127 DC brake cut-in frequency the frequency at which DC braking becomes active is selected. If a digital input is programmed to DC

braking inverse [5] and shifts from logic ’1’ to logic ’0’,

DC braking will be activated. When a stop command becomes active, DC braking is activated when the output frequency is less than the brake cut-in frequency.

NB!:

DC braking may not be used if the inertia in

the motor shaft is more than 20 times greater

than the motor’s internal inertia.
