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.
UnderstandingModuleConfigurationSwitches
The DeviceNet Communication module's DIPswitch settings determine:
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.

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
to perform a required function NOT covered by a common service.
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.

The internal update time (tint
) depends on thetype of data in question as there are differentchannels for the data transfer where time
critical data e.g. control word has highest
priority. The internal update time for thedifferent types of data are stated below.
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.
Control word as per Profidrive standard(parameter 512 = PROFIDRIVE)The control word is used for transmittingcommands from a master (e.g. a PC) to a slave
(VLT 5000 Series).

Bit 00, OFF1/ON1:An ordinary ramp stop which uses the ramptime in parameters 207/208 or 209/210. Bit00 = "0" leads to a stop and leads to output
relay 01 or 04 being activated, the outputfrequency is 0 Hz, provided Relay 123 hasbeen selected in parameter 323 or 326. Bit00 = "1" means that the adjustable frequencydrive will be able to start if the other conditionsfor starting have been fulfilled.
Bit 01, OFF2/ON2:Coasting stop. Bit 01 = "0" leads to a coastingstop and leads to output relay 01 or 04 beingactivated, when the output frequency is 0 Hz,provided Relay 123 has been selected in
parameter 323 or 326. Bit 01 = "1" meansthat the adjustable frequency drive is able tostart provided the other conditions for startingare fulfilled.
Bit 02, OFF3/ON3:Quick-stop, which uses the ramp time set inparameter 212. Bit 02 = "0" leads to a quickstop and leads to output relay 01 or 04 beingactivated, when the output frequency is 0 Hz,provided Relay 123 has been selected inparameter 323 or 326. Bit 02 = "1" meansthat the adjustable frequency drive is able to
start, provided the other conditions forstarting are fulfilled.
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

The frequency reference value is transmittedto the adjustable frequency drive in the formof a 16-bit word. The value is transmitted as
a whole number (0-32767). 16384 (4000 Hex)corresponds to 100%. (Negative figures areformatted by means of 2's complement.)
The bus reference has the following format:Parameter 203 = "0"
Special attention must be given to the followingparameters described in the VLT 5000 SeriesInstruction Manual:• 002: If operation site =Local, then control
via DeviceNet is not possible.• 502-508: Selection of how to gate DeviceNet
control commands with control commandson the digital inputs of the control card.
• 512: Control word profile, selects a controlword according to DeviceNet or a Danfossspecified control word.
• 515-538: Data read out parameters that can
be used to read various actual data fromthe VLT, as for example actual status onthe analog and digital inputs of the controlcard thus using these as inputs to themaster.
Function:Selec tion of the DeviceNet transmissionspeed. The selection must match thetransmission speed of the master and otherDeviceNet nodes.
Description of selections:• 125 - 500 kBaud : Selection of a fixedbaudrate will reduce the power up time as it

(SELECT SET UP 4) [7]
Function: The time out counter is triggered at the firstreception of a valid control word i.e. bit 10 =ok, when DP or cyclical FMS communication
is used. Acyclical FMS will not trigger the timeout counter. The time o ut function can beactivated in two different ways:1. CTW is not updated within the specified
time.2. Parameter 805 ="bit 10 =0 time out"
and bit 10 ="0". The VLT remains in time out state until oneof the following four conditions is true:1. Valid control word (Bit 10 =ok) is received
and reset (Bus, terminals or local controlpanel) is activated (reset is only necessary
when the time out functionStop w/ trip isselected) control via DeviceNet is resumedwith the actual control word.
2. Parameter 002 =Local Local control vialocal control panel is enabled.
3. Parameter 928 =Disabled Normal controlvia terminals and RS485 is enabled.
NOTE: The time out counter is reset and must betriggered by a valid control word before a newtime out can be activated.4. Parameter 804 =Off control via DeviceNet
is resumed and the most recent control word
is used.Description of Selections:• Freeze output frequency : Freeze output
frequency until communication is resumed.• Stop with auto restart : Stop with auto restart
when communication is resumed.• Output frequency = JOG freq .: Motor will

• Stop with trip: Motor is stopped, reset neededfor restart, see explanation above.
• Control without DeviceNet : Control viaDeviceNet is disabled and control is possiblevia terminals and/or standard RS485interface, until communication is resumed.
• Selec t set up 4 : Set up 4 is selected inparameter 004 and the settings of set up 4will be used. Parameter 004 is not reset tothe original value when communication isresumed.
Function:According to the DeviceNet profile, controlword and speed reference will be ignored if bit 10 of the control word is0 , but parameter
805 lets the user change the function of bit10. This is some times necessary as somemasters are setting all bits to 0 in variousfault situations. In these cases it makessense to change the function of bit 10 sothat the VLT is commanded to stop (coast)when all bits are0 .Description of Selections:• Bit 10 =1 CTW ac tive : Control word and
speed reference is ignored if bit 10 =0.• Bit 10 =0 CTW ac tive : Control word and
speed reference is ignored if bit 10 =1. If
all bits of the control word are 0 the VLTreaction will be coasting.• Bit 10 =0 time out : The time out function
selected in parameter 804 is activated whenbit 10 is0 .

Function:Refer to parameter 005 in the VLT 5000 SeriesInstruction Manual.
Function:Parameter values changed via DeviceNet isonly stored in RAM meaning that the changes
are lost at power down. This parameter is usedto activate a function that stores all parametervalues in the EEPROM thus retainingchanged parameter values at power down.Description of selections:No ac tion : The store function is inactive.Store data values : All parameter values willbe stored in the EEPROM. The value returnsto No action when all parameter values havebeen stored.
Function: The three parameters holds a list of all theparameters that are defined in the VLT. Eachof the three parameters can be read as an
array by means of the acyclical FMS readservice with subindex 255. It is also possibleto read single elements of the list by DP andcyclical/acyclical FMS by using thecorresponding subindex. The subindexes startat 1 and follows the order of the parameternumbers.Each parameter holds up to 116 elements(parameter numbers). The number of parameters (980, 981 and 982) in usedepends on the actual VLT configuration.When a 0 is returned as parameter number
the list ends.

User Interface The DeviceNet option card contains two bi-color(green/red) LED's for each connector hookupport, to indicate the state of the device andnetwork, respectively.
For the device status LED:1. when the LED is off, the device is off 2. when the LED is green, the device is
operational3. When the LED is flashing green, the device
is in standby4. when the LED is flashing red, the device
detects a minor fault5. when the LED is red, the device detects
an unrecoverable fault6. when the LED is flashing red/green, the
device is self testing
For the network status LED:1. when the LED is off, the network is non-powered/not online
2. when the LED is flashing green, thenetwork is online but not connected
3. when the LED is green, the network isonline and connected
4. when the LED is flashing red, the networkhas a connection time-out
5. when the LED is red, the network has acritical link failure.

There is a clear distinction between alarms andwarnings. In the case of an alarm, The VLT willenter a fault condition and act as defined in theControl Word. After the cause for the alarm hasbeen cleared, the master will have to
Any warning within the VLT is represented by asingle bit within a warning word. A warning word
is always an action parameter. Bit status FALSE[0] means no warning, while bit status TRUE [1]means warning. To each bit and each bit statusthere is a corresponding text string.
Following an Alarm message the VLT will enterFault condition. Only after the fault has beenalleviated and the master has acknowledged thealarm message by setting bit 7 in the ControlWord, can the VLT resume operation.
acknowledge the alarm message for the VLTto start operating again. A warning on theother hand may come when a warningcondition appears, and disappear whenconditions return to normal without interferingwith the process.
In addition to the warning word message themaster will also be notified through a changeof bit 7 in the Status Word.
Any warning within the VLT is representedby a single bit within a warning word. Awarning word is always an action parameter.Bit status FALSE [0] means no fault, whilebit status TRUE [1] means fault. To each bit
