  • Page 6: 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.

  • Page 7: Decentral Design Benefits

    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. ® MG.90.S1.02 - VLT is a registered Danfoss trademark...
  • Page 8 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. Illustration 1.3: Decentralised installation ® MG.90.S1.02 - VLT is a registered Danfoss trademark...
  • Page 9 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. ® MG.90.S1.02 - VLT is a registered Danfoss trademark...
  • Page 10 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.
  • Page 11 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.
  • Page 12 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.
  • Page 13 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.

    1.3 Application Examples Danfoss has completed a wide range of applications in many different industries. This has given us a valuable experience that has influenced the latest development of our decentralised products. In the following we provide illustrative examples of actual installations using Danfoss decentralised products, and the benefit and value these provide for the customer in these installations.

  • Page 30 FCD will interrupt the flow of current. 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.

  • Page 31: Servicing The Danfoss Decentral Products

    1.7 Servicing the Danfoss Decentral Products 1.7.1 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 decen- tralised products superior in a service situation.

    The Protective Extra Low Voltage (PELV) requirements stated in IEC 61800-5-1 are not fulfilled at altitudes above 2000 m (6562 ft.). For 200V frequency converters the requirements are not fulfilled at altitudes above 5000 m (16 404 ft.). Please contact Danfoss Drives for further information.

  • Page 34: Technology

    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.

    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 brake resistor should be fitted to a nonflammable material. For protection of the installation, a thermal relay is fitted that cuts out the frequency converter if the brake current is too high. Danfoss' 40% brake resistors contain a KLIXON switch. Flat pack resistors are self-protecting.
