VLT 6000 HVAC Ordering guideThis section makes it easier for you to specify andorder a VLT 6000 HVAC. Choice of frequency converterThe frequency converter should be chosen on thebasis of the given motor current at maximum loadon the system. The rated output current IVLT,N mustbe equal to or higher than the required motorcurrent.VLT 6000 HVAC is available for two mains voltageranges: 200-240 V and 380-460 V.

It isrecommended for installation in standard cabinets. RFI filterAs standard, the VLT 6000 HVAC has an integralRFI filter up to and including 7.5 kW (3 kW 200 V).IP 20 Bookstyle: This enclosure is designed forcabinet installation. It takes up a minimum of spaceand can be fitted side-by-side without installation ofextra cooling equipment.IP 20: This enclosure is used as standard enclosurefor VLT 6000 HVAC. It is ideal for cabinet installationin areas where a high degree of protection isrequired. This enclose also permits side-by-sideinstallation.IP 54: This enclosure can be fitted direct to the wall.Cabinets are not required. IP 54 units can also beinstalled side-by-side.Select a RFI filter for dampening of interference inaccordance with EN 55011-1A and EN 55011-1B.These RFI filters comply with EMC standards EN55011-1A, provided max. 150 m screened/armoured cable is used, and with EN 55011-1B,provided 50 m screened/armoured cable is used(Bookstyle max. 20 m screened/armoured). Harmonic filterThe harmonic currents do not directly affect theelectricity consumption, but they do increase theheat losses in the installation (transformers, cables).That is why in systems with a rather highpercentage of rectifier load it is important to keepthe harmonic currents at a low level in order toavoid transformer overloads and high cabletemperatures. Control unit (LCP)The VLT 6000 HVAC is available with or withoutcontrol unit (LCP); however, IP 54 units alwayscome with the control unit.This control unit makes up a complete interface forcontrol and programming of the VLT 6000 HVAC.The control panel is detachable and may - as analternative - be mounted up to 3 metres away fromthe VLT frequency converter, i.e. in a cabinet, bymeans of a fitting kit delivered with the unit.Data information is given in a 4-line alpha-numericaldisplay, which under normal operation is able tocontinuously show four operating data items andthree operating modes. During programming, all theinformation required for quickly and efficiently settingup VLT frequency converter parameters will beshown.4As standard, the VLT 6000 HVAC has coils in theintermediate circuit in order to ensure lowharmonic currents. This typically reduces theinput current IRMS by 40 %.As a supplement to the display, there are threeindicator lamps for voltage (ON), warning(WARNING) and alarm (ALARM).All VLT frequency converter parameter Setups canbe changed directly via the control panel.The following options are available:- Control panel LCP (only for IP 20 units).- LCP remote-mounting kit for remote control ofIP 00 and IP 20 units.- LCP remote-mounting kit for remote control ofIP 54.- 3 metre cable for LCP.MD.60.A2.02 - VLT is a registered Danfoss trademark
VLT 6000 HVAC Fieldbus protocolsDanfoss VLT frequency converters are able to fulfilmany different functions in an automated buildingmanagement system. The VLT frequency convertercan be integrated directly in an overall monitoringsystem.This means that detailed process data can betransmitted via serial communication. The protocolslisted below are based on a RS 485 bus systemwith a maximum transmission speed of 9600 bauds.As standard, the following protocols are supported:- Danfoss FC protocol- Johnson's Control Metasys N2- Landis & Staefa FLNA frequency converter can be set and applied in allbuilding management control systems.Status messages, warnings and alarms providevaluable assistance in visualising and assessingprocesses. Fieldbus optionsThe increasing need for information in buildingmanagement systems makes it necessary to collector visualise many different types of process data.Important process data can help the systemtechnician in the day-by-day monitoring of thesystem, which means that a negative development- e.g. an increase in energy consumption - can berectified in time.The substantial amount of data in large buildingsmay generate a need for a higher transmissionspeed than 9600 baud. Danfoss VLT 6000 HVAC isavailable with LonWorks or Profibus , both of whichhave higher performance than standard integratedserial communication.MD.60.A2.02 - VLT is a registered Danfoss trademark ProfibusProfibus is a fieldbus system with FMS and DP,which can be used for linking automation units,such as sensors and actuators, to the controls bymeans of a two-conductor cable.Profibus FMS is used if major communication tasksare to be solved at cell and system level by meansof large volumes of data.Profibus DP is an extremely fast communicationprotocol, made specially for communicationbetween the automation system and various units. LON - Local Operating NetworkLonWorks is an intelligent fieldbus system whichimproves the possibility of decentralising control, ascommunication is enabled between individual unitsin the same system (Peer-to-Peer).This means that there is no need for a big mainstation for handling all the signals of the system(Master-Slave). Signals are sent direct to the unitthat needs them via a common network medium.This makes communication much more flexible andthe central building state control and monitoringsystem can be changed into a dedicated buildingstate monitoring system whose task is to ensurethat everything is running as planned. If the potentialof LonWorks is fully utilised, sensors will also beconnected to the bus, which means that a sensorsignal can quickly be moved to another controller. Ifroom dividers are mobile, this is a particularly usefulfeature.Two feedback signals can be linked to the VLT 6000HVAC by means of LonWorks, thereby enabling theinternal PID regulator to regulate directly on the busfeedback.5

VLT 6000 HVAC LC filters for VLT 6000 HVACWhen a motor is controlled by a frequencyconverter, resonance noise will be heard from themotor. This noise, which is caused by the design ofthe motor, occurs each time one of the inverterswitches in the frequency converter is activated.Consequently, the resonance noise frequencycorresponds to the switching frequency of thefrequency converter.For the VLT 6000 HVAC, Danfoss offers a LC filter todampen the acoustic motor noise.This filter reduces the voltage rise time, the peakvoltage UPEAK and the ripple current I to the motor,thereby making current and voltage almostsinusoidal. The acoustic motor noise is thereforereduced to a minimum.Because of the ripple current in the coils, there willbe some noise from the coils. This problem can besolved entirely by integrating the filter in a cabinet orsimilar. Examples of the use of LC filtersSubmersible pumpsFor small motors with up to and including 5.5 kWrated motor power, use a LC filter, unless the motoris equipped with phase separation paper. Thisapplies e.g. to all wet running motors. If thesemotors are used without LC filter in connection witha frequency converter, the motor windings will shortcircuit. If in doubt, ask the motor manufacturerwhether the motor in question is equipped withphase separation paper.Well pumpsIf immersion pumps are used, e.g. submergedpumps or well pumps, the supplier should becontacted for clarification of requirements. It isrecommended to use a LC filter if a VLT frequencyconverter is used for immersion operations.Long motor cablesIf screened/armoured motor cables longer than 150m or unscreened/unarmoured motor cables longerthan 300 m are used, a LC filter should be applied.The LC filter reduces the capacitive earth leakagecurrents and the voltage peak loads.NB!:If a VLT frequency converter controls severalmotors in parallel, the motor cables must beadded up to give the total cable length.10MD.60.A2.02 - VLT is a registered Danfoss trademark
