The option card is designed to communicate

with other nodes using the DeviceNet defined

standard, this facilitates interoperability or the

ability to communicate with other DeviceNet

certified devices.

The option card allows DeviceNet compatible

masters to control, monitor, and supervise the

VLT ® 5000 adjustable frequency drive. The

option is designed to the DeviceNet System

Protocol for Vendors as a slave device.

The application program has the fol lowing

functions:

1. Support interger parameters through

the dual ported RAM.

2. Manipulate the dual ported RAM

parameters to interface with the CAN.

3. Monitor network activity "watchdog"

function to determine Master Slave

communication continuity.

network management master have a significant

influence on how the node functions on the

network

A DeviceNet network can support up to 64

nodes.

Control and supervision of the VLT 5000 will still

be possible through the standard parameter set.

Limitations

User Profile

Product and

Environment The DeviceNet Option Card is an interface

between the DeviceNet serial communication

bus and the VLT ® 5000 adjustable frequency

drive from Danfoss. The option card will function

as an integrated part of the drive.

DeviceNet is a distributed control network. The

DeviceNet protocol is embedded in the controller

option card and is a communication protocol

conforming to the Open DeviceNet Vendor

Association (ODVA) standard.

The option card allows DeviceNet compatible

controllers, sensors, and network management

tools to control, monitor, and supervise the VLT ®

5000 adjustable frequency drive.

A DeviceNet compatible device has the ability

to perform the following operations with the VLT ®

5000 over the DeviceNet network:

1. Control frequency references and send

drive control commands.

2. Monitor the status of the drive, access

alarm and warning messages, and

monitor drive and motor information.

3. Upload and download drive settings,

configure drives, and also perform the

operations defined in 1 and 2.

Therefore, the level of control and flexibility of

the VLT ® 5000 over the network depends on

the capabilities built into the controlling device.

The VLT ® 5000 will function as a slave on the

DeviceNet network. This depends on how the

system is installed. All addressing and linking to

nodes is done at installation time by a network

manager tool. The network installer and the

The end-user is a network manager programmer

or a controller who see the DeviceNet option

card as a transparent bridge to the VLT 5000.

The interface connection to the Dev iceNet

network is implemented through a CAN chip.

The two avai lable Unconnected Message

Manager (UCMM) will receive an explicit

message from the master to establish aconnection through the Connection Object

which directly links to the DeviceNet network.

established, through the DeviceNet Predefined

Master/Slave Group 2 Message set. Therefore,

the Danfoss VLT ® 5000 DeviceNet option card

will be capable of establishing two UCMM

explicit message connections, one predefinedMaster/Slave explicit message connection

(Group 2 messages), and one I/O polled

connection (Group 2 messages).

Therefore, VLT ® software changes relating to the

communication and dual ported RAM

interfacing will not be required.

Initialization of

VLT ® 5000 Interface

Watch-dogVLT ® 5000Keep-alive Function

Watch-dogDeviceNet OptionCard Keep-alive

Function

Network VariableHandling

The VLT ® 5000 interface is initialized in three

phases. The first two phases are initiated and

controlled by the VLT ® which will write

commands to the option card through the dual

port RAM.

Phase 1:

Is the initialization of the communication system.

During this phase the option card must respond

correctly to the VLT ® 5000 initialization command

or else the VLT ® will not function and display a

"No Option Init" message.

Phase 2:

Is the interface watchdog function performed

by the option card as the first operational action.

After completion of this phase, data can bepassed between the VLT ® 5000 and the option

card through the command channel in the dual

port RAM.

After initialization of the dual port RAM, this

function must be executed periodically within

100 ms. The watchdog message is a command

to one of the control channels of the dual port

The parameter access network variable is a

structure containing parameter number, data,

value, and a function code containing a read or

write command. The application program shall

receive the data, validate the data, convert thedata to the format of the VLT ® 5000 dual port

Phase 3:

The VLT ® 5000 will write to the Initialization

Channel of the dual port RAM which will set the

displacement values of the various channels

(Control Channel, Status Channel, CommandChannel 1, Command Channel 2, Command

Channel 3, Warning Channel, and Spontan

Channel), and the DeviceNet option card

software will read these displacements and

return a response to the VLT ® 5000 notifying

that the initialization was successful or an error

was obtained in the process.

During operation (after initialization) the dual port

RAM interface is supervised by a watch-dog in

the VLT ® 5000. The VLT ® 5000 will be kept "alive"

by cyclic writing to a channel in the dual portRAM by the watch-dog handler of the option

card.

DeviceNet NetworkManagementFunctions

The Unconnected Message Manager (UCMM)

provides for the dynamic establishment of

Explicit Messaging Connections. The UCMM

is responsible for processing Unconnected

Explicit Requests and Responses. Support of the UCMM requires a device to screen for the

The option card will stop sending a watchdog

signal to the VLT® 5000 when:

[1] The node has been disconnected from the

network.

[2] A network management tool has the option

card go Off-line.

[3] A hardware fault on the DeviceNet Option

Card PCB prevents reliable operation.

By withholding the watchdog message, the

VLT ® 5000 can detect a "Bus Time-out" and

enter secure, pre-defined state.

For recoverable errors such as [1] and [2] the

option card shall re-send the watchdog

message when the fault or condition has

disappeared such as after re-connection of the

node to the network.

DeviceNet is a low-level network that

standardizes communications between

industrial devices (sensors, limit switches) and

high level devices (controllers). The

communication network can be peer to peer

or master/slave. DeviceNet uses CAN

technology for Media Access Control and

Physical Signaling and it supports up to 64

nodes. DeviceNet also defines device profiles

for devices belonging to specific classes. For

other devices, a custom class must be defined

in order to make it DeviceNet compatible. Thisfurther enhances the interchangeability and

interoperability of the network. Each node on

the network has its own unique media access

control identifier (MAC ID) to distinguish it on

the network. The MAC ID is stored in the header

of the message which is split into four different

message groups. However, DeviceNet only

makes use of three message groups keeping

the fourth one for future use. If two nodes

attempt to get control of the network bus

simultaneously, the CAN protocol resolves the

issue by arbitration. A dominant bit (0) will winarbitration over a recessive bit (1).

Unconnected Explicit Request Message CAN

Identifier from all possible Source MAC IDs. If a

device transmits Unconnected Explicit Request

Messages it must also screen for the

Unconnected Explicit Response CAN Identifierfrom all possible Source MAC IDs.

For unrecoverable errors such as [3] the

application program shall permit logging of

network errors without resetting or restarting the

microprocessor. This will send information to a

network management tool that will allow

appropriate actions to be taken. The only way

to recover from a serious error is to re-initialize

the VLT ®

5000/DeviceNet option card by cyclingpower.

In case of serious VLT ® 5000 fault, the 68HC11

shall hold the CAN chip reset, thereby disabling

any communication to the node until the VLT ®

5000 has been re-initialized.

For the VLT ® 5000 adjustable frequency drive,

the option card will be slave node on the

DeviceNet network. The option card will be a

message server that will request and set

parameters in the VLT via a dual ported RAM

interface. The option card has an embedded

CAN controller that will screen all network

messages with a Mask and Match register. This

feature allows the option card to filter out any

unwanted messages from the network. The

option card will receive group 2 and group 3

messages. Group 2 messages allows the optioncard to use the predefined Master/Slave

connection set which identifies a use for all group

2 message identifiers. The ability to receive Group

3 messages allows the option card to also be an

Unconnected Explicit Message Manager

(UCMM) with the UCMM request and response

message identifier. Explicit message connections

are unconditionally point-to-point. Point-to-point

connections exist between two devices only.

Cable Cross Section

The screen of the DeviceNet cable must always

be connected to ground at both ends, that

means the screen must be connected to ground

in all stations connected to the DeviceNet

network. It is very important to have a low

impedance ground connection of the screen,

also at high frequencies. This can be obtained

by connecting the surface of the screen to

ground, for example by means of a cable clamp

or a conductive cable gland.

VLT 5000 Ser ies is provided with different

clamps and brackets to enable a proper ground

connection of the DeviceNet cable screen. The

screen connection is shown in the drawing.

It is important that all stations connected to the

DeviceNet network are connected to the same

earth potential. The earth connection must have

a low HF (high frequency) impedance. This canbe achieved by connecting a large surface area

of the cabinet to ground, for example by

mounting the VLT 5000 Series on a conductive

rear plate.

Especially when having long distances between

the stations in a DeviceNet network it can be

necessary to use additional potential equalizing

cables, connecting the individual stations to thesame earth potential.

Connection of theCable Screen

It is essential that the bus line be terminated

properly. A mismatch of impedance may result

in reflections on the line that will corrupt data

transmission.

The DeviceNet Option Card is provided with a

pluggable screw connector.

By using a pluggable screw connector as a

splice between two trunk lines, removal of

devices will not sever the network.

Bus Termination Strain relief, if required, must be provided by

the developer. In current installations of this type

of connector, the strain relief is attached to the

product.

NOTE:

Wires should not be installed while the network

is active. This will prevent problems such as

shorting the network supply or disrupting

communications.

recommended to obtain interference free

operation of the DeviceNet network. Additional

information on EMC can be found in the VLT 5000 Series Instruction Manual.

NOTE:

Relevant national and local regulations, for

example regarding protective earth connection,

must be observed.

It is recommended to use a master with galvanic

isolated bus driver and with over voltageprotection (e.g. zenerdiode).

The DeviceNet communication cable must be

kept away from motor and brake resistor cables

to avoid coupling of high frequency noise from

one cable to the other. Normally a distance of 8inches (200 mm) is sufficient, but it is generally

recommended to keep the greatest possible

distance between the cables, especially where

cables are running in parallel over long

distances.

ATTENTION:When you make changes to the switch settings, use a pointed instrument such

as a ball point pen. DO NOT use a pencil because damage may occur.

ATTENTION:Unpredictable operation may occur if you fail to check connections and DIP switch

settings for compatibility with your application. Unpredictable operation may resultin death, personal injury, and equipment damage.

ATTENTION:Hazard of injury or equipment damage may occur due to unintended or incorrectmachine motion. When a system is configured for the first time, the motor must

be disconnected from the machine or process during initial system testing.

NOTE: When setting the Communication Module's addressing Dip Switches, you must ensurethat each serial device on the network has a unique address. Also, all devices connected tothe network must be set at the same baud rate.

Object Modeling DeviceNet is defined using object modeling.Object modeling organizes data and proceduresinto one entity: the object.

An object is a collection of related services andattributes. Services are procedures an objectperforms. Attributes are characteristics ofobjects represented by values, which can vary.Typically, attributes provide status informationor govern the operation of an object. The valueassociated with an attribute may or may notaffect the behavior of an object. An object'sbehavior is an indication of how the objectresponds to particular events.

Classes categorize objects. A class defines a

particular type of object and defines thecharacteristics shared by all the objects withina class. For example, the human race could berepresented by the class "Human" with millionsof objects within it.

Objects within a class are called objectinstances. An object instance is the actualrepresentation of a particular object within aclass. Each instance of a class has the same

set of attributes, but has its own set ofattribute values, which makes each instancein the class unique.

Every person in the human race can berepresented by an instance within the class"Human." All humans have the same set ofattributes; eyes, ears age, gender, etc. Yet,because the values of each attribute vary,each of us looks different and performs indistinct ways.

A DeviceNet node is modeled as a collection ofobjects. The realization of this abstract objectmodel within a product depends on theimplementation. In other words, a procust

internally maps this object model in a fashionspecific to its implementation.

A Class of Objects within a DeviceNet Node

Each object instance of a Class in aDeviceNet node has the same set ofattributes, but has its own particular set ofattribute values. The figure illustrates, multiple

object instances within a particular class canreside in a DeviceNet node.

DeviceNet Node

Object Instances

A Class of

Objects

Term DefinitionObject An abstract representation of a particular component within a product.Class A set of objects that all represent the same kind of system component. A class isa generalization of an object. All objects in a class are identical in form and behavior,

but may contain different attribute values.Instance A specific and real (physical) occurrence of an object. For example: California isan instance of the object class State. The terms object, instance, and object instance

all refer to a specific Instance.

Attribute A description of an externally visible characteristic or feature of an object. Typically,attributes provide status information or govern the operation of an object. Attributesmay or may not affect the behavior of an object. For example: the ASCII name of

an object; and the repetition rate of a cyclic object.Behavior A specification of how an object acts. Actions result from different events the

object is aware of, such as receiving service requests, detecting internal faults, or elapsingtimers.

Service A function supported by an object and/or object class. DeviceNet defines a set ofcommon services and provides for the definition of object class-specific services.Object-specific services are those which are defined by a particular object class

VLT ResponseTime

The update time via the DeviceNet connectioncan be divided into two parts:1) The communication time, which is the time it

takes to transmit data from the master to the

slave (VLT with DeviceNet option).2) The internal update time, which is the time it

takes to transmit data between the VLT 5000control card and the DeviceNet option card.

Communication time (tcom

) depends on the actualtransmission speed (baudrate) and the type ofmaster in use. More data or lower transmissionspeed will increase the communication time.

General PurposeDiscrete I/O

The General Purpose Discrete I/O device I/O assemblies consist of:

five predefined input assemblies with single status bits

one product–specific input assembly with a single status bit

five predefine input assemblies with multiple status bits one product–specific input assembly with multiple status bits

five predefined output assemblies

one product–specific output assembly

The I/O Assembly Instance definitions in thissection define the format of the "data" attribute(attribute 3) for I/O Assembly Instances. I/OAssemblies support a hierarchy of motor control

devices. The device hierarchy includes motorstarters, soft starters, AC and DC drives, andservo drives. Assembly Instances are numberedwithin the hierarchy so that each device type isassigned a range of Assembly Instance

numbers, with higher functionality devicessupporting higher instance numbers. Devicesin the hierarchy can choose to supportinstance numbers that are lower than theirs

in the hierarchy. For example an AC drivemay choose to support some I/O Assembliesin the starter profile to make it easier tointerchange starters and drives within thesystem.

Bit 03, Coasting/enable:Coasting stop. Bit 03 = "0" leads to a stop. Bit03 = "1" means that the adjustable frequencydrive is able to stop, provided the other

conditions for starting are fulfilled. Note: inparameter 502 the choice is made as to how bit03 is to be combined (gated) with thecorresponding function in the digital inputs.

Bit 04, Quick-stop/ramp:Quick-stop which uses the ramp time inparameter 212. Bit 04 = "0" leads to a quick-stop. Bit 04 = "1" means that the adjustablefrequency drive is able to start, provided the otherconditions for starting are fulfilled. Note: Inparameter 503 the choice is made as to how dit

o4 is to be combined (gated) with thecorresponding function on the digital inputs.

Bit 05, Freeze output frequency/ramp enable:Bit 05 = "0" means that the given outputfrequency is maintained even if the reference ischanged. Bit 05 = "1" means that the adjustablefrequency drive is again able to regulate, andthe given reference is followed.

Bit 09, Jog 2 OFF/ON:Activation of pre-programmed speed inparameter 510 (Bus Jog 2). JOG 2 is onlypossible when Bit 04 = "0" and bits 00-03 ="1". If both JOG 1 and JOG 2 are activated (bits

08 and 09 = "1"), JOG 1 has the higher priority,which means that the speed programmed inparameter 509 will be used.

Bit 10, Data not valid/valid:Used for telling VLT 5000 whether the controlword is to be used or ignored. Bit 10 = "0"means that the control word is ignored. Bit

10 = "1" means that the control word is used.This function is relevant because the controlword is always contained in the telegram,regardless of the type of telegram used, i.e.it is possible to disconnect the control wordif it is not to be used in connection withupdating or reading of parameters.

Bit 11, No function/slow down:Used for reducing the speed reference by thevalue in parameter 219. Bit 11 = "0" meansthat there is no change of the reference. Bit

11 = "1" means that the reference is reduced.

Bit 12, No function/catch-up:Used for increasing the speed reference bythe value of parameter 219. Bit 12 = "0"means that the reference is increased. If bothslow down and catch-up are activated (bits11 and 12 = "1"), slow down has the higherpriority, i.e. the speed reference is reduced.

This function is only possible if Multi-Setupshave been selected in parameter 004.

NOTE: Parameter 507 is used for choosinghow bits 13/14 are to be combined (gated)with the corresponding function on the digitalinputs.

Bit 15, No function/reversing:

Reversing of the direction of rotation of themotor. Bit 15 = "0" leads to no reversing, bit15 = "1" leads to reversing.

Note that as a point of departure reversinghas been selected as Digital in parameter 506.Bit 15 only leads to reversing if bus , logical

or or logical and has been selected (logical

and , however, only together with terminal 19).

without the brake function.

WARN. 26Brake resistor power 100%(BRAKE PWR WARN 100%)

WARN. 27Brake transistor fault

(BRAKE IGBT FAULT): The brake transistor is monitored during

operation and if short-circuits, the brake

function is disconnected and the warning

comes up. The VLT adjustable frequency

drive will still be able to run, but since the

brake transistor has short-circuited,

substantial power will be transmitted to the

brake resistor, even if it is inactive.

WARNING: There is a risk of substantial power

being transmitted to the brake resistor

if the brake transistor has been

short-circuited.

WARN. 28

Brake resistor power 80%(BRAKE POWER WARN 80%) The power transmitted to the brake resistor is

calculated as a percentage, as a mean value

over the last 120 sec., on the basis of the

resistance value of the brake resistor

(parameter 401) and the intermediate circuit

voltage.

When the calculated mean power exceeds

80% of the monitoring limit for the brake

power (parameter 402), a warning will appear.

If the mean power exceeds 100% and the

power monitoring of the brake resistor is On

(parameter 403), the brake function will be

disconnected.

If power monitoring has been connected (Off),

a warning will come up and the brake function

will still be active, which involves a risk of

overheating the brake resistor.

Warnings(continued)

WARN. 9Inverter overload (INVERTER TIME): The electronic, thermal inverter protection

reports that the Adjustable frequency drive is

about to cut out because of an overload (toohigh current for too long). The counter for

electronic, thermal inverter protection has

reached 98%, where 100% leads to a trip.

WARN. 10Motor overtemperature (MOTOR TIME): According to the electronic thermal protection

(ETR), the motor is too hot. This warning will

only come up if Warning has been selected in

parameter 128.

WARN. 11Motor thermistor (MOTORTHERMISTOR): The thermistor or the thermistor connection

has been disconnected.

250% of the rated current) has been

exceeded.

WARN. 23Fault during brake test (BRAKE TEST

FAILED):If Warning has been selected in parameter

404, the warning will come when the brake

test spots a fault. The brake test runs after

power up and when the motor has stoppedvia one of its functions, coasting stop or

quick-stop. The brake test may fail for the

following reasons:

No brake resistor connected or fault in the

connections; defective brake transistor. This

warning means that the brake will be inactive,

while the VLT adjustable frequency drive will

be able to work without the brake function.
