VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Introduction About This Manual This manual provides comprehensive instructions on the installation and set up of the LonWorks Option Card for the VLT 5000, VLT 6000 and the VLT 8000 Adjustable Frequency Drive to communicate over a LonWorks network. Operation and Instruction Manual or VLT8000 Installation, Operation and Instruction Manual.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA LonWorks Overview LonWorks is both an existing standard and hardware developed by Echelon Corporation. Echelon's stated goal is to establish a commodity solution to the presently daunting problems of designing and building control networks. The result is LonMark Interoperability which makes it possible for independent network devices to operate together over a LonWorks network. The LonMark program was developed to address interoperability issues.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA VLT LonWorks The Danfoss VLT LonWorks option card is comprised of a control card with a NEURON Option Card chip and a memory card. When installed into the VLT adjustable frequency drive, the unit enables the drive to communicate with other devices on the LON.The VLT drive is designed to provide precision control of standard induction electrical motors. The drive receives three reference signals along with start/stop and reset commands from the network.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Message Passing (continued) knowledgments are generated by the network host processor without intervention of the application. Transaction IDs are used to keep track of messages and acknowledgments so that the application does not receive duplicate messages. An equally reliable service is request/response, where a message is sent to a node or group of nodes and individual responses are expected from each receiver.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Routers and Bridges A router (or bridge) is a special node that consists of two connected NEURON chips, each connected to a separate channel (see figure below). Routers and bridges pass packets back and forth between these channels. There are four types of routers. A repeater is the simplest form of router, simply forwarding all packets between the two channels. A bridge simply forwards all packets which match its domains between the two channels.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Wiring Installation Wiring The adjustable frequency drive generates a carrier frequency with a pulse frequency between 3 kHz and 14 kHz. This results in radiated frequency noise from the motor cables. It is very important that the LonWorks cable be isolated as much as possible from the drive output cabling to the motor. Use shielded wire rather than twisted-pair. Do not run LonWorks cabling and motor cables in parallel or in close proximity to one another.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Network Initialization of LonWorks Option Card The LonWorks option card contains a NEURON chip with a unique address. After hardware installation, initialize the LonWorks option card. Addressing nodes on the LonWorks network is performed at installation time by an installation tool or network management tool. Addressing requires the retrieval of a node’s NEURON ID. The NEURON ID is a 48 bit number that identifies every manufactured NEURON chip.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Free Topology Network Configuration The Free Topology Transceiver (FTT) system is designed to support free topology wiring and accommodates bus, star, loop or any combination of these topologies. The FTT transceiver located on the VLT LonWorks option card provides I/O functions. Flexible wiring capability simplifies system installation and makes it easy to add nodes for system expansion. The figures below represent five network topologies.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Network Termination Option The option of using termination on the LonWorks card is provided. The option card has a termination resistor built-in which is activated by the terminator switches. Use of the terminator is optional, depending upon the network configuration. If termination is provided elsewhere in the network, the termination function should be OFF. Terminator switches position functions are provided in the table below.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA System Performance Free topology system specifications and transmission specifications are described below. Both specifications should be met to ensure proper operation. The system designer may choose from a variety of cables, depending on cost, availability, and desired performance. Performance may vary with cable type. Contact Echelon for cable types and the characterization of system performance.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA LonWorks Card Diagnostic LEDs The LonWorks board includes two LEDs to display the communication status of the board, display the state of the NEURON chip, and respond to the network management Status LED The Status LED patterns are: “wink” command. The onboard LEDs are the Service LED (LED 1, red) and the Status LED (LED 2, green).

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Network Drive Control Input The most common functions for controlling the VLT Adjustable Frequency Drive from the LonWorks network are made readily available. Those functions and their descriptions are presented in the table below. The control word function accesses additional drive capabilities for network control. All references provided to the drive are added to the total reference value.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Reference 3 Network variable nviRefHz is an unsigned value. It represents the output frequency of the drive in Hz in open loop. It is rarely used in closed loop mode. Range: 0 - 6553.5. Control Word The input network variable nviControlWord is a 16-bit word that provides additional operational control of the drive, as listed in the table below.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Precedence of the stop commands is: 1. Coast stop 2. Quick stop 3. DC brake stop 4. Ramp stop Coast stop The drive output stops immediately and the motor coasts to a stop. • Drive display show UN.READY (unit ready) when coast stop is active. • Drive cannot run in any mode. • Parameter 503 (502), Coasting stop, determines interaction with input 27.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Drive Feedback to Network The VLT LonWorks option provides 22 output variables to the network containing important drive and motor feedback data. Feedback data is sent when there is a change in value. The VLT LonWorks option will only transmit bound network variables. Since some data changes continuously, the transmission rate of those variables is limited. Min send time specifies the minimum time between transmissions of variables.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Drive status NvoDrvStatus, nvoStatusWord, nvoDigitalInput, nvoAlarmWord, nvoWarning1 and nvoWarning2 are all 16 bit Boolean values using the SNVT_state variable type. Individual bits represent specific drive status states. The tables provided in Drive Status Bit Definitions define each bit. Drive output 1 Network variable nvoOutputPcnt provides an analog indication of drive operation.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA VLT Parameter Access A controller node can monitor or modify any VLT parameter by supporting the Parameter access command and the Parameter access response functions. These functions allow a controller complete access to the features of the VLT and the ability to configure drives with predefined settings, using the network variables nviParamCmd and nvoParamResp.
VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Parameter Access Error Codes In the event of an error message in response to a Parameter access command (see VLT Parameter Access), the VLT sends 0xff in value bit [0] and an error code in value [3]. Error code definitions are presented in the table below. Parameter Access Error Codes Exception Code Parameter Access Command and Response Examples Example 1: Interpretation 1 Illegal function for the addressed node 2 Illegal data address (i.e.
