��Rotating shafts and electrical equipment canbe hazardous. Therefore, it is stronglyrecommended that all electrical work conformto the National Electrical Code (NEC) and alllocal regulations. Installation, start-up andmaintenance should be performed only byqualified personnel.

Factory recommended procedures, included in this manual,should be followed. Always disconnect electrical power beforeworking on the unit.

Although shaft couplings or belt drives are generally notfurnished by the manufacturer, rotating shafts, couplings andbelts must be protected with securely mounted metal guardsthat are of sufficient thickness to provide protection againstflying particles such as keys, bolts and coupling parts. Evenwhen the motor is stopped, it should be considered “alive”as long as its controller is energized. Automatic circuits maystart the motor at any time. Keep hands away from the outputshaft until the motor has completely stopped and power isdisconnected from the controller.

Motor control equipment and electronic controls areconnected to hazardous line voltages. When servicing drivesand electronic controls, there will be exposed componentsat or above line potential. Extreme care should be taken toprotect against shock. Stand on an insulating pad and makeit a habit to use only one hand when checking components.Always work with another person in case of an emergency.Disconnect power whenever possible to check controls orto perform maintenance. Be sure equipment is properlygrounded. Wear safety glasses whenever working on electriccontrol or rotating equipment.

Safety Guidelines1. The drive must be disconnected from the AC line before

any service work is done.2. The “Stop/Off” key on the local control panel of the drive

Touching electrical parts may be fatal – even after equipment has been

disconnected from AC line. To be sure that capacitors have fully dis-

charged, wait 14 minutes after power has been removed before touching

any internal component.

��

does not disconnect the equipment from the AC line andis not to be used as a safety switch.

3. Correct protective grounding of the equipment must beestablished. The user must be protected against supplyvoltage and the motor must be protected againstoverload in accordance with applicable national and localregulations.

4. Ground currents are higher than 3 mA.

Warnings Against UnintendedStart1. While the drive is connected to the AC line, the motor

can be brought to a stop by means of external switchclosures, serial bus commands or references. If personalsafety considerations make it necessary to ensure thatno unintended start occurs, these stops are not sufficient.

2. During programming of parameters, the motor may start.Be certain that no one is in the area of the motor ordriven equipment when changing parameters.

3. A motor that has been stopped may start unexpectedlyif faults occur in the electronics of the drive, or if anoverload, a fault in the supply AC line or a fault in themotor connection or other fault clears.

4. If the “Local/Hand” key is activated, the motor can onlybe brought to a stop by means of the “Stop/Off” key oran external safety interlock.

NOTE:It is responsibility of user or person installingdrive to provide proper grounding and branchcircuit protection for incoming power andmotor overload according to National ElectricalCode (NEC) and local codes.

The Electronic Thermal Relay (ETR) is UL listed. VLTs provideClass 20 motor overload protection in accordance with theNEC in single motor applications, when VLT 6000 parameter117 (VLT 5000 parameter 128) is set for ETR Trip 1 andparameter 105 is set for rated motor (nameplate) current.

LONConcept

LonWorksOverview

Applications

LonWorks is both an existing standard andhardware developed by Echelon Corporation.Echelon's stated goal is to establish a com-modity solution to the presently dauntingproblems of designing and building controlnetworks.

The result is LonMark Interoperability whichmakes it possible for independent networkdevices to operate together over aLonWorks network. The LonMark programwas developed to address interoperabilityissues. As a result, the LonMarkInteroperability Association Task Groups(LonUsers Groups) were developed. Thetask groups determine that each device onthe network has an object definition, create

The LonWorks communications structure issimilar to that of a local area network (LAN)in that messages are continually exchangedbetween a number of processors. ALonWorks system is a determined localoperating network (LON). LON technologyoffers a means for integrating variousdistributed systems that perform sensing,monitoring, control, and other automatedfunctions. A LON allows these intelligentdevices to communicate with one anotherthrough an assortment of communicationsmedia using a standard protocol.

LON technology supports distributed, peer-to-peer communications. That is, individual

network devices can communicate directlywith one another without need for a centralcontrol system. A LON is designed to movesense and control messages which aretypically very short and which containcommands and status information thattrigger actions. LON performance is viewedin terms of transactions completed persecond and response time. Control systemsdo not need vast amounts of data, but theydo demand that the messages they sendand receive are absolutely correct. The criticalfactor in LON technology is the assuranceof correct signal transmission and verification.

An important LonWorks benefit is thenetwork’s ability to communicate acrossdifferent types of transmission media. TheNEURON chip is the heart of the LonWorkssystem. The NEURON chip's commu-nication port allows for the use oftransceivers for other media (such as coaxand fiber optic) to meet special needs.

LonWorks control devices are called nodes.Physically, each node consists of a NEURON

chip and a transceiver. With proper design,the nodes become building blocks that can

be applied to control a variety of tasks, suchas lighting or ventilating, integrating a varietyof communications media.

The tasks which the nodes perform aredetermined by how they have beenconnected and configured. Becausehardware design, software design, andnetwork design may be independent in aLonWorks-based system, a node’s functioncan be programmed to accommodate thenetworks in which it will be used.

standards and models to be used byparticular applications and create a commonplatform for presenting data. A standardnetwork variable type (SNVT) facilitatesinteroperability by providing a well definedinterface for communication betweendevices made by different manufacturers.The VLT Adjustable Frequency Drivesupports the node object and controllerstandard object definitions of LonMarkInteroperability.

Customers are currently using LonWorks forprocess control, building automation, motorcontrol, elevator operation, life safetysystems, power and HVAC distribution andsimilar intelligent building applications.

MessagePassing

NodeArrangements

LonWorks nodes can be addressed eitherindividually or in groups. A group can containup to 64 nodes, and one LonWorks networkcan support 255 groups. Furthermore, anynode can be part of 15 different groups. Asubnet, very similar to a group, can contain127 nodes. A domain is the largestarrangement of nodes with a single domainable to handle 255 subnets. Thus a domaincan handle 32,385 separate nodes. A singlenode may be connected to no more than twodomains.

The group structure has the advantage ofallowing a number of nodes to be reached atonly one address. This method reduces the

record keeping inside each chip to a minimum,allowing faster operation. However, highefficiency individual addressing can be doneat all levels of a LonWorks system. Theaddress table of a node contains entries forthe group type and size and tells the nodehow many acknowledgments to expect whenit sends a message. It also tells the NEURON

chip which domain to use and the node groupmember number, which identif ies anacknowledgment as coming from the node.The address also contains a transmit timer, arepeat timer, a retry counter, a receive timer,and the group ID.

There are a number of trade-offs betweennetwork efficiency, response time, security,and reliability. Generally, LonWorks defaults tothe greatest degree of safety and verificationfor all communications over the LON network.The LonTalk protocol, built into the chips, isthe operating system that coordinates theLonWorks system. It offers four basic typesof message service.

The most reliable service is acknowledged (orend-to-end acknowledged service), where amessage is sent to a node or group of nodesand individual acknowledgments are ex-pected from each receiver. If anacknowledgment is not received from all des-tinations, the sender times out and re-triesthe transaction. The number of retries andtime-out duration are both selectable. Ac-

VLT LonWorksOption Card

The Danfoss VLT LonWorks option card iscomprised of a control card with a NEURON

chip and a memory card. When installed intothe VLT adjustable frequency drive, the unitenables the drive to communicate with otherdevices on the LON. The VLT drive is designedto provide precision control of standardinduction electrical motors. The drive receivesthree reference signals along with start/stopand reset commands from the network. Thedrive also receives a 16-bit control word thatprovides full operational control of the drive.(See Network Drive Control Input for additionaldetails.)

In response, the drive provides 16 outputnetwork variables containing important driveand motor data. (See Drive Feedback toNetwork.) Output to the network includesdrive status, current, voltage, motor andinverter thermal status, and alarms andwarnings.

LonWorks supports many different types oftransmission media. A LonWorks networkphysical layer option can be transformercoupled twisted pair (78 kbps and 1.25Mbps), free topology, link power, power line,RF, RS-485, fiber optic, coaxial, or infrared.

The VLT LonWorks option supports fourtransmission media with three versions of theVLT LonWorks option card. The VLTLonWorks option card versions are:

1. Free topology, which also operates ona link power network.

2. 78 kbps transformer coupled twistedpair.

3. 1.25 Mbps transformer coupled twistedpair.

A router is required to interface to a LonWorksnetwork when not supported by one of thethree option card versions.


VLT® 5000 / VLT® 6000

CollisionDetection

NetworkManagement

Depending on the level of a given application,a LonWorks network may or may not requirethe use of a network management node. Anetwork management node performsmanagement functions, such as:

• Find unconfigured nodes anddownload their network addresses.

• Stop, start, and reset nodeapplications.

• Access node communication statistics.• Configure routers and bridges.• Download new applications programs.• Extract the topology of a running

network.

The LonTalk protocol uses a unique collisionavoidance algorithm which allows anoverloaded channel to carry near to itsmaximum capacity, rather than reducing itsthroughput due to excessive collisionsbetween messages. When using acommunications medium that supportscollision detection, such as twisted pair, theLonTalk protocol can optionally canceltransmission of a packet as soon as a collisionis detected by the transceiver. This option

allows the node to immediately retransmit anypacket that has been damaged by a collision.Without collision detection, the node wouldwait the duration of the retry time to noticethat no acknowledgment was received. At thattime it would retransmit the packet, assumingacknowledge or request/response service.For unacknowledged service, an undetectedcollision means that the packet is not receivedand no retry is attempted.

knowledgments are generated by the networkhost processor without intervention of the ap-plication. Transaction IDs are used to keeptrack of messages and acknowledgments sothat the application does not receive dupli-cate messages.

An equally reliable service is request/response,where a message is sent to a node or groupof nodes and individual responses are ex-pected from each receiver. Incomingmessages are processed by the applicationon the receiving side before a response isgenerated. The same retry and time-out op-tions are available as with acknowledgedservice. Responses may include data, so thatthis service is particularly suitable for remoteprocedure call or client/server applications.

Next in reliability is unacknowledged repeated.Messages are sent multiple times to a nodeor a group of nodes with no responseexpected. This service is typically used whenbroadcasting to large groups of nodes whentraffic generated by all the responses wouldoverload the network.

The final method in reliability is unac-knowledged, where a message is sent onceto a node or group of nodes and no responseis expected. This option is typically used whenthe highest performance is required, networkbandwidth is limited, and the application isnot sensitive to the loss of a message.

VLT® 5000 / VLT® 6000

Routers andBridges

A router (or bridge) is a special node thatconsists of two connected NEURON chips, eachconnected to a separate channel (see figurebelow). Routers and bridges pass packetsback and forth between these channels. Thereare four types of routers. A repeater is thesimplest form of router, simply forwarding allpackets between the two channels. A bridgesimply forwards all packets which match itsdomains between the two channels. Using abridge or repeater, a subnet can exist acrossmultiple channels. A learning router monitorsthe network traffic and learns the networktopology at the domain/subnet level. Thelearning router then uses its knowledge toselectively route packets between channels.Like a learning router, a configured routerselectively routes packets between channelsby consulting internal routing tables. Unlike alearning router, the contents of the internalrouting tables are specified using networkmanagement commands.

Initially, each router sets its internal routing tablesto indicate that all subnets could lie on either sideof the router. Suppose that node 6, in the figurebelow, generates a message bound for node 2.Learning router 1 initially picks up the message.It examines the source subnet field of themessage and notes in its internal routing tables

Learning RoutersSource: Echelon Corp.

that subnet 2 lies below it. The router thencompares the source and destination subnet IDsand, since they are different, the message ispassed on. Meanwhile, learning router 2 alsopasses the message on, making an appropriatenotation in its internal routing tables regarding thelocation of subnet 2.

Suppose now that node 2 generates anacknowledgment. This acknowledgment ispicked up by learning router 1, which now notesthe location of subnet 1. Learning router 1examines its internal routing tables, and, notingthat subnet 2 lies below, passes the messageon. When the message appears on subnet 2, itis noted by both node 6 (the destination) andlearning router 2. Learning router 2 does not passit on but merely notes that subnet 1, like subnet2, lies somewhere above. Learning router 2 willnot learn of the existence or location of subnet 3until a message is originated from there. Subnetscannot cross routers. While bridges andrepeaters allow subnets to span multiplechannels, the two sides of a router must belongto separate subnets. Since routers are selectiveabout the packets they forward to each channel,the total capacity of a system can be increasedin terms of nodes and connections.

NetworkInitializationof LonWorksOption Card

LonMarkXIF Files

A LonMark interface file (.XIF extension)provides the host processor with deviceinformation. With this, it is possible to designa LonWorks network without the adjustablefrequency drive being physically present.The VLTLON.XIF can be downloaded fromthe Internet site www.danfoss.com/drives. TheLonWorks option card does not contain aninternal interface file.

Echelon Corporation has also developed a setof free plug-ins available through their web siteat www.echelon.com/plugin/default.htm. Alsointended for network design, these plug-insprovide easy access to screens which simplifythe process of manually setting up the drive,testing, and monitoring operation.

The drive may also be added to the networkupon initialization.

The LonWorks option card contains a NEURON

chip with a unique address. After hardwareinstallation, initialize the LonWorks option card.Addressing nodes on the LonWorks networkis performed at installation time by aninstallation tool or network management tool.Addressing requires the retrieval of a node’sNEURON ID. The NEURON ID is a 48 bit numberthat identifies every manufactured NEURON

chip. There are several methods by which thenetwork software will initialize the driveautomatically. The network can recognize thedrive without action beyond properinstallation. The card is then ready to beprogrammed for network operation. The VLTLonWorks option supports three additionalmethods of addressing a node:

1. Service Pin - There are twomomentary-contact service switches thatsend the NEURON ID over the network. If thenetwork software prompts the action, press

either service pin (SW1 or SW3) to transmitthe NEURON ID over the network. The servicepin locations are shown in the illustration inTerminator and Service Switch Locations inthis manual.

2. Query and Wink - The LonWorks optioncard is shipped with a domain of “0” andsubnet of “1.” Upon receiving the winkcommand, the on-board green status LEDflashes so that the installer can locate thenode. The chip sends out its Neuron ID overthe network in response to the querycommand.

3. NEURON ID Label - The VLT LonWorksoption card has a NEURON ID label thatdisplays the NEURON ID as a 12 digithexadecimal number. The installer canmanually enter the NEURON ID duringinstallation.

The VLT LonWorks network interface consistsonly of SNVTs. The SNVTs support theLonMark Controller Profile along with VLTconfiguration, control and monitoringcapabilities. Any combination of SNVTs canbe used to operate the VLT.

NetworkDriveControlInput

The most common functions for controllingthe VLT Adjustable Frequency Drive from theLonWorks network are made readily available.Those functions and their descriptions arepresented in the table below. The control wordfunction accesses additional drive capabilitiesfor network control.

The choice of open loop or closed loopoperation of the drive is selected in parameter100, Configuration.

Using nviRefPcnt, the drive's reference isexpressed as a percentage of the referencerange. The range is set using parameters 204,Min. Reference and 205, Max. Reference. Inopen loop operation, reference represents thedrive's desired output speed. In this case, setMin. Reference to 0 Hz and Max. Referenceequal to Max. Frequency in parameter 202.

In closed loop operation, reference representsthe desired setpoint. It is recommended thatparameters 204 and 205 be set equal toparameters 201, Min. Frequency and 202,Max. Frequency.

All references provided to the drive are addedto the total reference value. If reference is tobe controlled by the LonWorks bus only,ensure that all other reference inputs are zero.This means that digital input terminals and

variable inputs to the VLT. Configuration ofparameters needs setting only one time,usually at installation.

Start/Stop and Reset faultSNVT_lev_disc. ST_OFF and ST_NUL areinterpreted as low or “0.” ST_LOW, ST_MED,ST_HIGH, and ST_ON are interpreted as highor “1.”

NOTETo optimize network performanceand for proper drive operation,use only one of following inputreference commands.

Reference 1Network variable nviRefPcnt is a signed value.It represents the desired percentage of theVLT drive's reference range.

analog input terminals should not be used forreference signals. The default setting (0%)should be maintained for preset references inparameters 211 (215) through 214 (218). Also,in closed loop operation, the default setting(0.0) should be maintained for drive setpointsin parameters 418 (215) and 419 (218).

VLT 5000 parameters are shown in parenthesis, where applicable.

DriveFeedback toNetwork

The VLT LonWorks option provides 16 outputvariables to the network containing importantdrive and motor feedback data. Feedback datais sent when there is a change in value. TheVLT LonWorks option will only transmit boundnetwork variables. Since some data changescontinuously, the transmission rate of thosevariables is limited. Min send time specifiesthe minimum time between transmissions ofvariables.

The Drive Outputs (1, 2, or 3) will have amaximum time between transmission set by theMax send time. This function acts as a transmitheartbeat and allows a controller node todetermine the health of the controller/VLTconnection. The Max send time function isdisabled when the configuration networkvariable nciMaxsendT is not configured or is setto “0.”

Drive statusNvoDrvStatus, nvoStatusWord, nvo-DigitalInput, nvoAlarmWord, nvoWarning1 andnvoWarning2 are all 16 bit Boolean valuesusing the SNVT_state variable type. Individualbits represent specific drive status states. Thetables provided in Drive Status Bit Definitionsdefine each bit.

Drive output 1Network variable nvoOutputPcnt provides ananalog indication of drive operation. In openloop, this is the drive output frequency inpercentage within the reference range. Toavoid negative numbers, or numbers above100%, set parameter 204, Min. Reference to0 Hz, and parameter 205, Max. Referenceequal to parameter 202, Max. Frequency.

Max receive timeThis drive function is replaced by the valueset in parameter 803, Bus Time Out. TheLonWorks option will initiate bus time outactivities when the time set in parameter 803expires without receiving an input networkvariable directed to the drive. This acts like aLonWorks receive heartbeat. The action takenby the drive is determined by the settingselected in parameter 804, Bus time outfunction. See the parameter descriptionsection of this manual. The value ofnciMaxReceiveT has no effect on theoperation of the drive.

NetworkTimerFunctions

Max send timeThis function sets the maximum time betweentransmissions for the network variables DriveOutput 1, 2, and 3 using the configurationnetwork variable nciMaxSendT. It can be usedby the controller to monitor the health of theVLT and controller connection. It acts like aLonWorks send heartbeat.

The Max send time function is disabled whennciMaxSendT is not configured or set to “0.”

VLT® 5000 / VLT® 6000

A controller node can monitor or modify anyVLT parameter by supporting the Parameteraccess command and the Parameter accessresponse functions. These functions allow acontroller complete access to the features ofthe VLT and the ability to configure drives withpredefined settings, using the networkvariables nviParamCmd and nvoParamResp.

The following definitions describe how thefields of SNVT_preset are used by the VLTLonWorks option:

LearnThis field contains the function code for theVLT. The values for this field are:

LN_RECALL (0),LN_LEARN_CURRENT (1),LN_LEARN_VALUE (2), andLN_REPORT_VALUE (3).

LN_RECALL (0) andLN_REPORT_VALUE (3)are interpreted as read commands.

LN_LEARN_CURRENT (1) andLN_LEARN_VALUE (2)are interpreted as write commands.

Any other value in this field will result in anerror message in the Parameter accessresponse.

SelectorThis field contains the VLT parameternumber, written in decimal notation, that isto be written or read. Requests forundefined parameters will result in an errormessage in the Parameter access esponse.

VLTParameterAccess

The controlling device should compare theparameter number of the responsemessage to the requested parameternumber to determine that the informationreceived is the requested information andnot a response to another controller or fromanother VLT.

ValueThis array contains the parameterinformation to and from the VLT. All VLTparameters use 16 bit signed or unsignedvalues. The most significant 2 hex bytes ofdata will be stored in value [0] and the leastsignificant 2 hex bytes of data will be storedin value [3]. In the event of an errormessage, the VLT will send 0xff in value [0]and an error code in value [3]. The errorcodes are defined in the section ParameterAccess Error Codes in this manual.

Example 1:

The examples below demonstrate use of theparameter access command and parameteraccess response functions of the controllernode. In the examples, the controller node hasa parameter access command SNVT_presetcalled nvoParamCmd and a parameteraccess response SNVT_preset callednviParamResp. In writing to the drive correctly,the access response simply repeats theentered data. In the event of an error, an errorcode is displayed in value [3]. See ParameterAccess Error Codes above.

ParameterAccessError Codes

In the event of an error message in responseto a Parameter access command (see VLTParameter Access), the VLT sends 0xff in value

bit [0] and an error code in value [3]. Errorcode definitions are presented in the tablebelow.

Example 3:

Example 4:

A controller node writes 18.0 Hz to VLTparameter 201, Output Frequency Low Limit.The conversion index is -1, so the conversionfactor is 0.1.


nvoParamCmd.learn =LN_LEARN_CURRENTnvoParamCmd.selector = 201nvoParamCmd.value[0] = 0nvoParamCmd.value[1] = 0nvoParamCmd.value[2] = 0nvoParamCmd.value[3] = B4 hex (180decimal)

StandardObjectSupport

The VLT LonWorks option supports twostandard objects and three SNVTs, per theLonMark standard object philosophy. Thestandard objects are the Node Object(containing the Object request, Object status,and Object alarm) and the Controller object,(containing the network variables describedin the preceding sections). The Object requestis a LonMark device used to obtain status andalarm information from a node.

It is not necessary for a controller to supportthe Node Object network variables. TheObject request, Object status and Objectalarm provide status and alarm informationfor controllers that only support this type offunctionality. The status and alarm functionsdescribed in the preceding sections containmore drive specific information than Objectstatus and Object alarm.

1. The VLT sends an Object statuscontaining drive status informationand an Object alarm containing faultinformationin response to thefollowing Object requests:

RQ_NORMAL,RQ_UPDATE_STATUS, andRQ_UPDATE_ALARM.

Network Variables for Node Object Support

Function SNVT type Variable Name Input/Output

Object request SNVT_obj_request nviRequest Input

Object status SNVT_obj_status nvoStatus Output

Object alarm SNVT_alarm nvoAlarm Output

A controller node error is written to VLTparameter 201, Output Frequency Low Limit,with 80.0 Hz when the high limit is 60 Hz. Theconversion index is -1, with conversion factor 0.1.


nvoParamCmd.learn =LN_LEARN_CURRENTnvoParamCmd.selector = 201nvoParamCmd.value[0] = 0nvoParamCmd.value[1] = 0nvoParamCmd.value[2] = 3 hexnvoParamCmd.value[3] = 20 hex (800decimal)

The nviRequest.object_id should be setto “1” (controller node). The networkuses nviRequest, nvoStatus andnvoAlarm variables for these functions.

2. The VLT sends an Object statuscontaining a bit map of supportedstatus fields in response to all otherObject requests, including undefinedrequests.

3. The VLT Object status supports thefollowing status fields: invalid_id,invalid_request,open_circuit,out_of_service, electrical_fault,comm_failure, manual_control, andin_alarm. All other fields are alwaysset to “0.”

4. The VLT sends an Object alarmfollowing any set or reset of a drivefault condition.

5. The Object alarm supports theAL_ALM_CONDITION andAL_NO_CONDITION alarm types.

Function:The time out timer is triggered at the firstreception of a valid control word, i.e.,bit 10 = ok.

The time out function can be activated in twodifferent ways:

1. The drive does not receive aLonWorks command addressed to itwithin the specified time.

2. Parameter 805 is set to “bit 10 = 0time out” and a control word with “bit10 = 0” is sent to the drive.

The VLT remains in the time out state untilone of the following four conditions is true:

1. A valid control word (Bit 10 = ok) isreceived and the drive is resetthrough the bus, the digital inputterminals or the local control panel.(Reset is only necessary when thetime out function Stop w/trip isselected.) Control via LonWorks isresumed using the received controlword.

2. Local control via the local controlpanel is enabled.

3. Parameter 928, Access to processcontrol, is set to Disabled.Normal control via the digital inputterminals and the RS-485 interface isnow enabled.

★ Factory setting

4. Parameter 804, Bus time out function,is set to Off.Control via LonWorks is resumed andthe most recent control word is used.

Description of Selections:

• Freeze output frequency. Maintainpresent output frequency untilcommunication is resumed.

• Stop with auto restart. Stop andautomatically restart whencommunication is resumed.

• Output frequency = JOG freq. Drivewill produce JOG frequency set inparameter 209 (213), Jog frequency,until communication is resumed.

• Output frequency = Max. freq. Drivewill produce maximum outputfrequency (set in parameter 202,Output frequency) untilcommunication is resumed.

• Stop with trip. Drive stops andrequires a reset command before itwill restart.

• Control without LonWorks. Control viaLonWorks is disabled. Control ispossible via digital input terminalsand/or standard RS-485 interfaceuntil LonWorks communication isresumed.

• Select setup 4. Setup 4 is selected inparameter 002 (004), Active setup,and settings of setup 4 are used.Parameter 002 (004) is not reset tothe original value whencommunication is resumed.

Parameter 805 lets the userchange the function of bit 10. This is sometimes necessary, as some masters set all bitsto 0 in various fault situations. In these cases,it makes sense to change the function of bit10 so that the VLT is commanded to stop(coast) when all bits are 0.

Description of Selections:• No function. Bit 10 is ignored, i.e.,

control word and speed reference arealways valid.

• Bit 10 = 1 >CTW active. The controlword and speed reference areignored if bit 10 = 0.

• Bit 10 = 0 >CTW active. The controlword and speed reference areignored if bit 10 = 1. If all bits of thecontrol word are 0, the VLT reactionwill be coasting.
