Danfoss VLT 5000 Instruction Manual

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA ������ � Rotating shafts and electrical equipment can be hazardous. Therefore, it is strongly recommended that all electrical work conform to the National Electrical Code (NEC) and all local regulations. Installation, start-up and maintenance should be performed only by qualified personnel. Factory recommended procedures, included in this manual, should be followed. Always disconnect electrical power before working on the unit. Although shaft couplings or belt drives are generally not furnished by the manufacturer, rotating shafts, couplings and belts must be protected with securely mounted metal guards that are of sufficient thickness to provide protection against flying particles such as keys, bolts and coupling parts. Even when the motor is stopped, it should be considered “alive” as long as its controller is energized. Automatic circuits may start the motor at any time. Keep hands away from the output shaft until the motor has completely stopped and power is disconnected from the controller. Motor control equipment and electronic controls are connected to hazardous line voltages. When servicing drives and electronic controls, there will be exposed components at or above line potential. Extreme care should be taken to protect against shock. Stand on an insulating pad and make it 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 or to perform maintenance. Be sure equipment is properly grounded. Wear safety glasses whenever working on electric control or rotating equipment. Safety Guidelines 1. 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 and is not to be used as a safety switch. 3. Correct protective grounding of the equipment must be established. The user must be protected against supply voltage and the motor must be protected against overload in accordance with applicable national and local regulations. 4. Ground currents are higher than 3 mA. Warnings Against Unintended Start 1. While the drive is connected to the AC line, the motor can be brought to a stop by means of external switch closures, serial bus commands or references. If personal safety considerations make it necessary to ensure that no 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 or driven equipment when changing parameters. 3. A motor that has been stopped may start unexpectedly if faults occur in the electronics of the drive, or if an overload, a fault in the supply AC line or a fault in the motor connection or other fault clears. 4. If the “Local/Hand” key is activated, the motor can only be brought to a stop by means of the “Stop/Off” key or an external safety interlock. NOTE: It is responsibility of user or person installing drive to provide proper grounding and branch circuit protection for incoming power and motor overload according to National Electrical Code (NEC) and local codes. The Electronic Thermal Relay (ETR) is UL listed. VLTs provide Class 20 motor overload protection in accordance with the NEC in single motor applications, when VLT 6000/8000 parameter 117 (VLT 5000 parameter 128) is set for ETR Trip 1 and parameter 105 is set for rated motor (nameplate) current.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA LON Concept LonWorks Overview Applications LonWorks is both an existing standard and hardware developed by Echelon Corporation. Echelon's stated goal is to establish a com- modity 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. As a result, the LonMark Interoperability Association Task Groups (LonUsers Groups) were developed. The task groups determine that each device on the network has an object definition, create The LonWorks communications structure is similar to that of a local area network (LAN) in that messages are continually exchanged between a number of processors. A LonWorks system is a determined local operating network (LON). LON technology offers a means for integrating various distributed systems that perform sensing, monitoring, control, and other automated functions. A LON allows these intelligent devices to communicate with one another through an assortment of communications media using a standard protocol. LON technology supports distributed, peer- to-peer communications. That is, individual network devices can communicate directly with one another without need for a central control system. A LON is designed to move sense and control messages which are typically very short and which contain commands and status information that trigger actions. LON performance is viewed in terms of transactions completed per second and response time. Control systems do not need vast amounts of data, but they do demand that the messages they send and receive are absolutely correct. The critical factor in LON technology is the assurance of correct signal transmission and verification. An important LonWorks benefit is the network’s ability to communicate across different types of transmission media. The NEURON chip is the heart of the LonWorks system. The NEURON chip's commu- nication port allows for the use of transceivers for other media (such as coax and 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, such as lighting or ventilating, integrating a variety of communications media. The tasks which the nodes perform are determined by how they have been connected and configured. Because hardware design, software design, and network design may be independent in a LonWorks-based system, a node’s function can be programmed to accommodate the networks in which it will be used. standards and models to be used by particular applications and create a common platform for presenting data. A standard network variable type (SNVT) facilitates interoperability by providing a well defined interface for communication between devices made by different manufacturers. The VLT Adjustable Frequency Drive supports the node object and controller standard object definitions of LonMark Interoperability. Customers are currently using LonWorks for process control, building automation, motor control, elevator operation, life safety systems, power and HVAC distribution and similar intelligent building applications.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Message Passing Node Arrangements LonWorks nodes can be addressed either individually or in groups. A group can contain up to 64 nodes, and one LonWorks network can support 255 groups. Furthermore, any node can be part of 15 different groups. A subnet, very similar to a group, can contain 127 nodes. A domain is the largest arrangement of nodes with a single domain able to handle 255 subnets. Thus a domain can handle 32,385 separate nodes. A single node may be connected to no more than two domains. The group structure has the advantage of allowing a number of nodes to be reached at only one address. This method reduces the record keeping inside each chip to a minimum, allowing faster operation. However, high efficiency individual addressing can be done at all levels of a LonWorks system. The address table of a node contains entries for the group type and size and tells the node how many acknowledgments to expect when it sends a message. It also tells the NEURON chip which domain to use and the node group member number, which identifies an acknowledgment as coming from the node. The address also contains a transmit timer, a repeat timer, a retry counter, a receive timer, and the group ID. There are a number of trade-offs between network efficiency, response time, security, and reliability. Generally, LonWorks defaults to the greatest degree of safety and verification for all communications over the LON network. The LonTalk protocol, built into the chips, is the operating system that coordinates the LonWorks system. It offers four basic types of message service. The most reliable service is acknowledged (or end-to-end acknowledged service), where a message is sent to a node or group of nodes and individual acknowledgments are ex- pected from each receiver. If an acknowledgment is not received from all des- tinations, the sender times out and re-tries the transaction. The number of retries and time-out duration are both selectable. Ac- VLT LonWorks Option Card The Danfoss VLT LonWorks option card is comprised of a control card with a NEURON 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. The drive also receives a 16-bit control word that provides full operational control of the drive. (See Network Drive Control Input for additional details.) In response, the drive provides 16 output network variables containing important drive and motor data. (See Drive Feedback to Network.) Output to the network includes drive status, current, voltage, motor and inverter thermal status, and alarms and warnings. LonWorks supports many different types of transmission media. A LonWorks network physical layer option can be transformer coupled twisted pair (78 kbps and 1.25 Mbps), free topology, link power, power line, RF, RS-485, fiber optic, coaxial, or infrared. The VLT LonWorks option supports four transmission media with three versions of the VLT LonWorks option card. The VLT LonWorks option card versions are: 1. Free topology, which also operates on a link power network. 2. 78 kbps transformer coupled twisted pair. 3. 1.25 Mbps transformer coupled twisted pair. A router is required to interface to a LonWorks network when not supported by one of the three option card versions.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Collision Detection Network Management Depending on the level of a given application, a LonWorks network may or may not require the use of a network management node. A network management node performs management functions, such as: • Find unconfigured nodes and download their network addresses. • Stop, start, and reset node applications. • 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 collision avoidance algorithm which allows an overloaded channel to carry near to its maximum capacity, rather than reducing its throughput due to excessive collisions between messages. When using a communications medium that supports collision detection, such as twisted pair, the LonTalk protocol can optionally cancel transmission of a packet as soon as a collision is detected by the transceiver. This option allows the node to immediately retransmit any packet that has been damaged by a collision. Without collision detection, the node would wait the duration of the retry time to notice that no acknowledgment was received. At that time it would retransmit the packet, assuming acknowledge or request/response service. For unacknowledged service, an undetected collision means that the packet is not received and no retry is attempted. knowledgments are generated by the network host processor without intervention of the ap- plication. Transaction IDs are used to keep track of messages and acknowledgments so that the application does not receive dupli- cate messages. An equally reliable service is request/response, where a message is sent to a node or group of nodes and individual responses are ex- pected from each receiver. Incoming messages are processed by the application on the receiving side before a response is generated. The same retry and time-out op- tions are available as with acknowledged service. Responses may include data, so that this service is particularly suitable for remote procedure call or client/server applications. Next in reliability is unacknowledged repeated. Messages are sent multiple times to a node or a group of nodes with no response expected. This service is typically used when broadcasting to large groups of nodes when traffic generated by all the responses would overload the network. The final method in reliability is unac- knowledged, where a message is sent once to a node or group of nodes and no response is expected. This option is typically used when the highest performance is required, network bandwidth is limited, and the application is not sensitive to the loss of a message. Message Passing (continued)

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. Using a bridge or repeater, a subnet can exist across multiple channels. A learning router monitors the network traffic and learns the network topology at the domain/subnet level. The learning router then uses its knowledge to selectively route packets between channels. Like a learning router, a configured router selectively routes packets between channels by consulting internal routing tables. Unlike a learning router, the contents of the internal routing tables are specified using network management commands. Initially, each router sets its internal routing tables to indicate that all subnets could lie on either side of the router. Suppose that node 6, in the figure below, generates a message bound for node 2. Learning router 1 initially picks up the message. It examines the source subnet field of the message and notes in its internal routing tables Learning Routers Source: Echelon Corp. that subnet 2 lies below it. The router then compares the source and destination subnet IDs and, since they are different, the message is passed on. Meanwhile, learning router 2 also passes the message on, making an appropriate notation in its internal routing tables regarding the location of subnet 2. Suppose now that node 2 generates an acknowledgment. This acknowledgment is picked up by learning router 1, which now notes the location of subnet 1. Learning router 1 examines its internal routing tables, and, noting that subnet 2 lies below, passes the message on. When the message appears on subnet 2, it is noted by both node 6 (the destination) and learning router 2. Learning router 2 does not pass it on but merely notes that subnet 1, like subnet 2, lies somewhere above. Learning router 2 will not learn of the existence or location of subnet 3 until a message is originated from there. Subnets cannot cross routers. While bridges and repeaters allow subnets to span multiple channels, the two sides of a router must belong to separate subnets. Since routers are selective about the packets they forward to each channel, the total capacity of a system can be increased in terms of nodes and connections. 9 10 11 12 1 2 3 4 5 6 7 8 R R Channel Channel Channel Subnet 1 Subnet 3 Subnet 2 Learning Router 1 Learning Router 2

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Wiring Installation VLT adjustable frequency drive contains dangerous voltages when connected to line power. After disconnecting from line, wait at least 14 minutes before touching any electrical com- ponents. Only a competent electrician should carry out electrical installation. Improper installation of motor or VLT can cause equipment failure, serious injury or death. Follow this manual, National Electrical Code (USA) and local safety codes. ������� � ������� � ������� � Electronic components of VLT adjustable frequency drives are sensitive to electrostatic dis- charge (ESD). ESD can reduce performance or destroy sensitive electronic components. Follow proper ESD procedures during installation or servicing to prevent damage. It is responsibility of user or installer of VLT adjustable frequency drive to provide proper grounding and motor overload and branch protection according to National Electrical Code (USA) and local codes. ������ � W W W W Wiring iring iring iring iring 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. Ensure that the drive is properly grounded. The following section describes the installation procedures for the LonWorks option card (see following illustration).

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Network Initialization of LonWorks Option Card Resource files A LonMark interface file (.XIF extension) provides the host processor with device information. With this, it is possible to design a LonWorks network without the adjustable frequency drive being physically present. The resource files (VLTLON.XIF and DanfossVSD_03.*) can be downloaded from the Internet site www.danfoss.com/drives. Echelon Corporation has also developed a set of free plug-ins available through their web site at www.echelon.com/plugin/default.htm. Also intended for network design, these plug-ins provide easy access to screens which simplify the process of manually setting up the drive, testing, and monitoring operation. 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. There are several methods by which the network software will initialize the drive automatically. The network can recognize the drive without action beyond proper installation. The card is then ready to be programmed for network operation. The VLT LonWorks option supports three additional methods of addressing a node: 1. Service Pin - There are two momentary-contact service switches that send the NEURON ID over the network. If the network software prompts the action, press either service pin (SW1 or SW3) to transmit the NEURON ID over the network. The service pin locations are shown in the illustration in Terminator and Service Switch Locations in this manual. 2. Query and Wink - The LonWorks option card is shipped with a domain of “0” and subnet of “1.” Upon receiving the wink command, the on-board green status LED flashes so that the installer can locate the node. The chip sends out its Neuron ID over the network in response to the query command. 3. NEURON ID Label - The VLT LonWorks option card has a NEURON ID label that displays the NEURON ID as a 12 digit hexadecimal number. The installer can manually enter the NEURON ID during installation. The drive may also be added to the network upon initialization. The VLT LonWorks network interface consists of SNVTs and SCPT. The SNVTs support the LonMark Controller Profile along with VLT configuration, control and moni- toring capabilities. Any combination of SNVTs can be used to operate the VLT. We also support the Functional Profile for Variable Speed Drives version 1.1 from the LonMark organisation.This profile defines a set of Network variables (SNVT) and configuration properties (SCPT).

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Network Variable Inputs to VLT 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. The choice of open loop or closed loop operation of the drive is selected in parameter 100, Configuration. Using nviRefPcnt, the drive's reference is expressed as a percentage of the reference range. The range is set using parameters 204, Min. Reference and 205, Max. Reference. In open loop operation, reference represents the drive's desired output speed. In this case, set Min. Reference to 0 Hz and Max. Reference equal to Max. Frequency in parameter 202. In closed loop operation, reference represents the desired setpoint. It is recommended that parameters 204 and 205 be set equal to parameters 201, Min. Frequency and 202, Max. Frequency. Start/Stop and Reset fault SNVT_lev_disc. ST_OFF and ST_NUL are interpreted as low or “0.” ST_LOW, ST_MED, ST_HIGH, and ST_ON are interpreted as high or “1.” NOTE To optimize network performance and for proper drive operation, use only one of following input reference commands. Reference 1 Network variable nviRefPcnt is a signed value. It represents the desired percentage of the VLT drive's reference range. Range: -163.840 - 163.835. All references provided to the drive are added to the total reference value. If reference is to be controlled by the LonWorks bus only, ensure that all other reference inputs are zero. This means that digital input terminals and analog input terminals should not be used for reference signals. The default setting (0%) should be maintained for preset references in parameters 211 (215) through 214 (218). Also, in closed loop operation, the default setting (0.0) should be maintained for drive setpoints in parameters 418 (215) and 419 (218).

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Drive Feedback to Network The VLT LonWorks option provides 16 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. The Drive Outputs (1, 2, or 3) will have a maximum time between transmission set by the Max send time. This function acts as a transmit heartbeat and allows a controller node to determine the health of the controller/VLT connection. The Max send time function is disabled when the configuration network variable nciMaxsendT is not configured or is set to “0.” Network Variable Outputs from VLT Function SNVT type Variable Name Units Max Min Drive status SNVT_state nvoDrvStatus 16 Boolean NA NA Drive output 1 SNVT_lev_percent nvoOutputPcnt 0.005% 163.835 –163.840 Current 1) SNVT_amp nvoDrvCurnt 0.1 amps 3276.7 0 Energy SNVT_elec_kwh nvoDrvEnrg 1 kWh 65,535 0 Power 1) SNVT_power_kilo nvoDrvPwr 0.1 kW 6553.5 0 Statusword SNVT_state nvoStatusWord 16 Boolean NA NA Drive output 3 SNVT_freq_hz nvoOutputHz 0.1 Hz 6553.5 0 Output voltage SNVT_volt nvoVoltage 0.1 V 3276.7 –3276.8 Digital input SNVT_state nvoDigitlInput 16 Boolean NA NA Alarm SNVT_state nvoAlarmWord 16 Boolean NA NA Warning 1 SNVT_state nvoWarning1 16 Boolean NA NA Warning 2 SNVT_state nvoWarning2 16 Boolean NA NA DC voltage SNVT_volt nvoDCVolt 0.1 V 3276.7 0 Motor therm.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Drive status NvoDrvStatus, nvoStatusWord, nvo- DigitalInput, 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. In open loop, this is the drive output frequency in percentage within the reference range. To avoid negative numbers, or numbers above 100%, set parameter 204, Min. Reference to 0 Hz, and parameter 205, Max. Reference equal to parameter 202, Max. Frequency. In closed loop, this is the drive's feedback signal within the reference range. For best operation, set Min. Reference to equal parameter 413 (414), Min. Feedback, and Max. Reference to equal parameter 414 (415), Max. Feedback. Drive output 2 and Drive Output 3 Output 2 is useful in open loop to report the drive's output frequency in rad/sec. Output 3 in open loop reports the drive's output in Hz. Note that in closed loop nvoOutputHz will report the actual Feedback and not the output frequency. For best results, set Min. Reference to 0 Hz and Max. Reference equal to Max. Frequency. These variable are rarely used in closed loop.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Min send time Sets the minimum period between transmissions for all output network variables, using the network variable nciMinSendT. This function is used to keep the transmission of variables that change continuously from dominating the network communication. Max receive time This drive function is replaced by the value set in parameter 803, Bus Time Out. The LonWorks option will initiate bus time out activities when the time set in parameter 803 expires without receiving an input network variable directed to the drive. This acts like a LonWorks receive heartbeat. The action taken by the drive is determined by the setting selected in parameter 804, Bus time out function. See the parameter description section of this manual. The value of nciMaxReceiveT has no effect on the operation of the drive. Network Timer Functions Max send time This function sets the maximum time between transmissions for the network variables Drive Output 1, 2, and 3 using the configuration network variable nciMaxSendT. It can be used by the controller to monitor the health of the VLT and controller connection. It acts like a LonWorks send heartbeat. The Max send time function is disabled when nciMaxSendT is not configured or set to “0.” Function SNVT Variable Units Max Min Default type Name Min send SNVT nciMin- time 0 days 0 days 0 days time _elapsed SendT 0 hours 0 hours 0 hours _tm 1 min 0 min 0 min 5 sec 0 sec 0 sec 535 msec 100 msec1 500 msec 30 msec2 Max SNVT nciMax- time 0 days 0 days 0 days receive _elapsed ReceiveT 18 hours 0 hours 0 hours time _tm 12 min 0 min 0 min 15 sec 1 sec 0 sec 0 msec 0 msec 0 msec (Off) Max SNVT nciMax- time 0 days 0 days 0 days send _elapsed SendT 0 hours 0 hours 0 hours time _tm 1 min 0 min 0 min 5 sec 0 sec 0 sec 535 msec 100 msec1 0 msec 30 msec2 (Off) 1 78 kbps transformer coupled twisted pair and 78 Kbps free topology transceiver models. 2 1.25 Mbps transformer coupled twisted pair transceiver model.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA 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. The following definitions describe how the fields of SNVT_preset are used by the VLT LonWorks option: Learn This field contains the function code for the VLT. The values for this field are: LN_RECALL (0), LN_LEARN_CURRENT (1), LN_LEARN_VALUE (2), and LN_REPORT_VALUE (3). LN_RECALL (0) and LN_REPORT_VALUE (3) are interpreted as read commands. LN_LEARN_CURRENT (1) and LN_LEARN_VALUE (2) are interpreted as write commands. Any other value in this field will result in an error message in the Parameter access response. Selector This field contains the VLT parameter number, written in decimal notation, that is to be written or read. Requests for undefined parameters will result in an error message in the Parameter access esponse. VLT Parameter Access The controlling device should compare the parameter number of the response message to the requested parameter number to determine that the information received is the requested information and not a response to another controller or from another VLT. Value This array contains the parameter information to and from the VLT. All VLT parameters use 16 bit signed or unsigned values. The most significant 2 hex bytes of data will be stored in value [0] and the least significant 2 hex bytes of data will be stored in value [3]. In the event of an error message, the VLT will send 0xff in value [0] and an error code in value [3]. The error codes are defined in the section Parameter Access Error Codes in this manual. NOTE Consult Conversion Index in the VLT Instruction Manual parameter table for correct conversion factor for reading and writing to and from drive. Day, Hour, Minute, Second, Millisecond The time fields are not supported by the VLT LonWorks option. The VLT will respond to parameter access requests as soon as they are received. Any values in the time fields of the Parameter access command will be ignored. All time fields will be set to “0” in the Parameter access response.

In the examples, the controller node has a parameter access command SNVT_preset called nvoParamCmd and a parameter access response SNVT_preset called nviParamResp. In writing to the drive correctly, the access response simply repeats the entered data. In the event of an error, an error code is displayed in value [3]. See Parameter Access Error Codes above. 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 Command and Response Examples Parameter 971 must be set to STORE ACTIVE SETUP for entering data values through LonWorks parameter access command in order to save changes in drive. See parameter 971 in Parameter Descriptions section of this manual. NOTE Consult conversion index in the VLT Instruction Manual parameter table for correct conversion factor for reading and writing to and from drive. ������� � The controller node writes 30 seconds to parameter 206 (205), Ramp time up of the VLT. Conversion index is 0, so the conversion factor is 1.0 (VLT 5000 conversion factor -2)). The controller node access command sends the following parameter write request to the VLT. nvoParamCmd.learn= LN_LEARN_CURRENT nvoParamCmd.selector = 206 nvoParamCmd.value[0] = 0 nvoParamCmd.value[1] = 0 nvoParamCmd.value[2] = 0 nvoParamCmd.value[3] = 1E hex (30 decimal) The controller node receives the following parameter access response from the VLT. nviParamResp.learn = LN_LEARN_CURRENT nviParamResp.selector = 206 nviParamResp.value[0] = 0 nviParamResp.value[1] = 0 nviParamResp.value[2] = 0 nviParamResp.value[3] = 1E hex nviParamResp.day = 0 nviParamResp.hour = 0 nviParamResp.minute = 0 nviParamResp.second = 0 nviParamResp.millisecond = 0 VLT 5000 parameters are shown in parenthesis, where applicable.

VLT® 5000 / VLT® 6000 HVAC / VLT® 8000 AQUA Standard Object Support The VLT LonWorks option supports two standard objects and three SNVTs, per the LonMark standard object philosophy. The standard objects are the Node Object (containing the Object request, Object status, and Object alarm) and the Controller object, (containing the network variables described in the preceding sections). The Object request is a LonMark device used to obtain status and alarm information from a node. It is not necessary for a controller to support the Node Object network variables. The Object request, Object status and Object alarm provide status and alarm information for controllers that only support this type of functionality. The status and alarm functions described in the preceding sections contain more drive specific information than Object status and Object alarm. 1. The VLT sends an Object status containing drive status information and an Object alarm containing fault informationin response to the following Object requests: RQ_NORMAL, RQ_UPDATE_STATUS, and RQ_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 VLT parameter 201, Output Frequency Low Limit, with 80.0 Hz when the high limit is 60 Hz. The conversion index is -1, with conversion factor 0.1. The controller node sends the following parameter write request to the VLT. nvoParamCmd.learn = LN_LEARN_CURRENT nvoParamCmd.selector = 201 nvoParamCmd.value[0] = 0 nvoParamCmd.value[1] = 0 nvoParamCmd.value[2] = 3 hex nvoParamCmd.value[3] = 20 hex (800 decimal) The controller node receives the following parameter access response from the VLT. nviParamResp.learn = LN_NULL nviParamResp.selector = 201 nviParamResp.value[0] = 0 nviParamResp.value[1] = 0 nviParamResp.value[2] = 0 nviParamResp.value[3] = 3 (illegal data value) nviParamResp.day = 0 nviParamResp.hour = 0 nviParamResp.minute = 0 nviParamResp.second = 0 nviParamResp.millisecond = 0 The nviRequest.object_id should be set to “1” (controller node). The network uses nviRequest, nvoStatus and nvoAlarm variables for these functions. 2. The VLT sends an Object status containing a bit map of supported status fields in response to all other Object requests, including undefined requests. 3. The VLT Object status supports the following status fields: invalid_id, invalid_request,open_circuit, out_of_service, electrical_fault, comm_failure, manual_control, and in_alarm. All other fields are always set to “0.” 4. The VLT sends an Object alarm following any set or reset of a drive fault condition. 5. The Object alarm supports the AL_ALM_CONDITION and AL_NO_CONDITION alarm types. Example 5:

(MAX SPEED) [4] Stop with trip (STOP AND TRIP) [5] Control without DeviceNet (NO COM OPT CONTROL) [6] Select set-up 4 (SELECT SET UP 4) [7] Function: The time out timer is triggered at the first reception of a valid control word, i.e., bit 10 = ok. The time out function can be activated in two different ways: 1. The drive does not receive a LonWorks command addressed to it within the specified time. 2. Parameter 805 is set to “bit 10 = 0 time out” and a control word with “bit 10 = 0” is sent to the drive. The VLT remains in the time out state until one of the following four conditions is true: 1. A valid control word (Bit 10 = ok) is received and the drive is reset through the bus, the digital input terminals or the local control panel. (Reset is only necessary when the time out function Stop w/trip is selected.) Control via LonWorks is resumed using the received control word. 2. Local control via the local control panel is enabled. 3. Parameter 928, Access to process control, is set to Disabled. Normal control via the digital input terminals and the RS-485 interface is now enabled. # Factory setting 4. Parameter 804, Bus time out function, is set to Off. Control via LonWorks is resumed and the most recent control word is used. Description of Selections: • Freeze output frequency. Maintain present output frequency until communication is resumed. • Stop with auto restart. Stop and automatically restart when communication is resumed. • Output frequency = JOG freq. Drive will produce JOG frequency set in parameter 209 (213), Jog frequency, until communication is resumed. • Output frequency = Max. freq. Drive will produce maximum output frequency (set in parameter 202, Output frequency) until communication is resumed. • Stop with trip. Drive stops and requires a reset command before it will restart. • Control without LonWorks. Control via LonWorks is disabled. Control is possible via digital input terminals and/or standard RS-485 interface until LonWorks communication is resumed. • Select setup 4. Setup 4 is selected in parameter 002 (004), Active setup, and settings of setup 4 are used. Parameter 002 (004) is not reset to the original value when communication is resumed. VLT 5000 parameters are shown in parenthesis, where applicable.

Parameter 805 lets the user change the function of bit 10. This is some times necessary, as some masters set all bits to 0 in various fault situations. In these cases, it makes sense to change the function of bit 10 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 are always valid. • Bit 10 = 1 >CTW active. The control word and speed reference are ignored if bit 10 = 0. • Bit 10 = 0 >CTW active. The control word and speed reference are ignored if bit 10 = 1. If all bits of the control word are 0, the VLT reaction will be coasting. • Bit 10 = 0 >time out. The time out function selected in parameter 804 is activated when bit 10 is 0. Data Value: Disable (DISABLE) [0] # Enable (ENABLE) [1] This parameter determines LonWorks control of the drive. When Enable is selected, drive parameters 503 through 508 determine the interaction between various LonWorks and digital drive input commands. See the VLT Instruction Manual for details. When this parameter is set to Store active setup, LonWorks downloaded parameters are written to EEPROM and stored. Store edit setup stores the setup selected in parameter 970. Store all setups stores all setups in parameter 970. When finished (appx. 15 sec.), it automatically returns to No action. Any parameters values written via the serial bus with No action selected are lost when power is removed from the drive. The function is only activated with the VLT in stop mode.
