Unit Software version

FCM 300 Not supported FCD 300 Ver. 1.3x/2.x VLT 2800 Ver. 2.6x/2.x

This manual gives detailed information of the DP V0 features supported, sufficient for most programming and maintenance activities. The DP V1 however is briefly described. For programming purposes

the Profibus DP V1 Design Guide order number

MG.90.EX.YY (X is the version number, and YY the language code) might be necessary.

It is suggested that readers who are not completely familiar with PROFIBUS DP or the profile for frequency converters review the relevant literature on these subjects.

Even if you are an experienced PROFIBUS programmer, we suggest that you read this manual in its entirety before you start programming, since important information can be found in all chapters.

■Assumptions

This manual assumes that you are using a DANFOSS FCM 300, FCD 300 or VLT 2800 w ith PROFIBUS. It is also assumed that you, as a master, are using a PLC or PC that is equipped with a serial communication card supporting all the PROFIBUS communication services required by your application. Further, it is assumed that all requirements stipulated in the PROFIBUS standard as well as those set up in the PROFIBUS frequency converters Profile and its company-specific implementation PROFIDRIVE, as well as those pertaining to the frequency converter are strictly observed as well as all limitations therein fully respected.

FCM 300 / FCD 300 / VLT®2800 / DP V1 PROFIBUS

Introduction

The Profibus DP V1 replaces the former Profibus DP V0 functionality. Note: The 3MB and 12MB Profibus option are separate options and have different ordering numbers.

■What you should already know

The DANFOSS PROFIBUS is designed to communicate with any master abiding by the PROFIBUS DP standard. It is therefore assumed that you have full knowledge of the PC or PLC you intend to use as a master in your system. Any questions pertaining to hardware or software produced by any other manufacturer is beyond the scope of this manual and is of no concern to DANFOSS.

If you have questions about how to set up master

- master communication or communication to a non-Danfoss slave, the appropriate manuals should be consulted.

FCM 300 / FCD 300 / VLT®2800 / DP V1 PROFIBUS

■Quick start

Details regarding the programming of the usual frequency converter parameters may be gathered from the Design Guide for the FCM 300, the FCD 300 and VLT 2800.

The communication is established by setting the parameters indicated below.

Details regarding the adjustment of the m aster are provided by the master manual and by those chapters in this manual that deal with the particulars of the VLT PROFIBUS interface.

NB!:

The required GSD file is available on the internet at http://www.danfoss.com/drives.

■Profibus DP

arameter 904 The desired informative data telegram (PPO) is setup in master configuration. The actual PPO type c an be read out in P904. The master sends the PPO type in a configuration telegram in the Profibus DP start phase.

arameter 918 This sets the address of the frequency converter station – one specific address per frequency converter. For further information, please refer to the section Station address in this manual.

arameter 502 -508 By setting the parameters 502-508 you will be able to select have to control over the bus.

arameter 512 Allows the choice of Control word/Status word type. For further information, please refer to the section Control word/Status word this manual.

NB!:

In order to activate a change of parameter 918 the power of the frequency converter must be cycled.

■Baudrate

The FCM 300, FCD 300 and VLT 2800 adjust automatically to the Baudrate configurated from the master.

NB!:

When configuring the PPO types, a distinction is made between module consistency andwordconsistency:

Module consistency means that a specific portion of the PPO is defined as a connected module. The parameter interface (PCV, length of 8 bytes) of the PPO always has m odule consistency.

Word consistency means that a specific portion of the PPO is divided into individual data sectors of word length (16 bits).

The process data of the PPO may have either module consistency or word consistency, as desired.

Some PLCs, such as Siemens S7, require special functions to call m odules that are longer than 4 bytes (in the case of Siemens: "SFC", see master manual). This means that the PCV interfaces of the PPOs c an only be called through the SFC functions in the case of Siemens (S7).

■Profibus DP V1

A detailed description of the DV V1 features supported can be found in the "Profibus DP V1 Design Guide" order number MG.90.EX.YY.

■Master-controlled frequency converters

The PROFIBUS Fieldbus was designed to give you unprecedented flexibility and command over your controlled system. The PROFIBUS will perform as an integrated part of your frequency converter, giving you access to all parameters relevant to your application. The frequency converter will always act as a slave, and together with a master it can exchange a multitude of information and commands. Control signals such as speed reference, start / stop of motor, reverse operation, etc. are transmitted from the master in the form of a telegramme. The frequency converter acknowledges receipt by transmitting status signals, such as running, on reference, motor stopped and so on to the master. The frequency converter may also transmit fault indications, alarms and warnings to the master, such as Overcurrent or Phaseloss.

The PROFIBUS communicates in accordance with the PROFIBUS field bus standard, EN 50170, part 3. It can thus exchange data with all masters that me et this standard; however, this does n ot mean that all services ava ilable in the PROFIDRIVE profile standard are supported. The PROFIBUS profile for frequency converters (version 2 and partly version 3, PNO) is a part of PROFIBUS which supports only those services that concern applications with speed control.

ommunication partners In a control system the frequency converter will always act as a slave, and as such it may communicate with a single master or multiple masters depending on the nature of the application. A master may be a PLC or a PC that is equipped with a PROFIBUS communication card.

■Features of DP (Distributed Periphery)

- Is used by several PLC manufacturers for remote peripheral I/O communication.

- Supports cyclical communication.

- SRD (Send Receive Data) service gives fast cyclical exchange of process data between master and slaves.

- Freeze and synchronize function is supported.

- Fixed data structure.

- Fixed telegramme size.

- Occupies I/O memory space in PLC proportional to the number of slaves employed, which may

limit the number of participants. Additional data require additio nal I/O memory space.

DP should be used when fast cyclical process control is needed. Such a concept would typically call for single master operation with a limited number of slave stations. A high number of slaves will increase the system response time.

This could also be the case where control loops are closed over the bus. As a very fast alternativeitisofcoursepossibletoclosethe control loop outside the bus.

■Rapid Cyclical transmission with PPO using DP Control of the drives during normal operation is often

very time critical, but it involves very few data, such as control commands and speed reference. DP is optimized for fast cyclical communication.

Parameter up-/downloads can be achieved by using the PCV part of the so-called Parameter Process data Objects - PPO types 1, 2 or 5, see drawing in paragraph PPO description.

■Profibus DP V1

The Profibus DP extension DP V1 offers additional to the cyclical data communication an acyclica l communication. This feature can be used by a DP master type 1 (e.g. PLC), as well as a DP master type 2 (e.g. PC tool).

Features of a Master type 1 connection

- Cyclical data exchange (DP V0).

- Acyclical read/write on parameters.

The acyclical connection is fixed, and can not be changed during operation.

Features of a Master type 2 connection:

- Initiate / Abort acyclical connection.

- Acyclical read/write on parameters.

The acyclical connection can dynamically be established (Initiate) or removed (Abort) even when a master class 1 is active on the network.

The DP V1 acyclical connection can be used for general parameter access as an alternative to the PCV parameter channel.

■Principleofdata exchange by ProfibusDPV0/DPV1

InaDPcycletheMC1willfirstupdatethecyclical process da ta for all slaves in the system. After that the MC 1 has the possibility of sending one acyclical message to one slave. If a MC 2 is connected, the MC 1 will handle over the Token to MC 2 who now is a loud to send one acyclical message to one slave. After that, the token is handled back to the MC 1, and a new DP cycle is started.

■FCM 300/FCD 300/VLT 2800 response time

The update time via the prodibus connection can be divided in two parts: 1) The communication time, which is the time it takes to transmit data from the master to the slave (FCM 300/FCD 300/VLT 2800 with profibus), and 2) the internal update time, which is the time it takes to transmit data between the FCM 300/FCD 300/VLT 2800 control card and the profibus.

Communication time (t

com

) depends on the actual transmission speed (baudrate) and the type of master in use. The minimum obtainable communication time with the FCM 300/FCD 300/VLT 2800 with PROFIBUS is approx. 100 msec per slave, when using DP communication with 4 bytes of data (PPO type 3) at 3 Mbaud. More data or lower transmission speed will increase the communication time.

The internal update time (t

int

) depends on the type of data in question as there are different channels for the data transfer where time critical data e.g. control word has highest priority. The internal update time for the different types of data are stated below.

■Cable lengths/ number of nodes

The maximum cable length in one segment is depending on the transmission speed. The total cable length includes drop cables if any. A drop cable is the connection from the main bus cable to each node if a T-connection is used instead of connecting the main bus cable directly to the nodes, see drop cable ength. The table below shows the maximum allowed cable length and maximum number of nodes/frequency converters with 1, 2, 3 and 4 bus segments. Note that a repeater is a node in both of the two segments it connects. The number of frequency converters is based on a single master system. If

there are more masters the number of frequency converters must be reduced correspondingly.

The Profibus

Interface

■Physical connection

The PROFIBUS is connected to the bus line via X100, terminals 1 and 2.

It is recommended to use a master with a galvanic isolated bus driver and with over voltage protection (e.g. zenerdiode).

MC precautions The following EMC precautions are recommended to obtain interference free operation of the PROFIBUS network. Additional information on E MC can be found in the design guide on the FCM 300 (MG.03.BX.02). Please also consult the manual of the PROFIBUS master for further installation guidelines.

■Connection of the cable screen

The screen of the PROFIBUS 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 PROFIBUS 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.

The FCM 300 Series is provided with different clamps and brackets to enable a proper ground connection of the P ROFIBUS cable screen. The screen connection is shown in the following drawing.

NB!:

Relevant national and local regulations, for example regarding protective earth connection, must be observe d.

■Cable connection F CM 300

The PROFIBUS communica tion 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 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.

If the PROFIBUS cable has to cross a motor and braking resistance cable, it should occur at a 90° angle.

■Earth connection

It is important that all stations connected to the PROFIBUS network are connected to the same

earth potential. The earth connection must have a low HF (high frequency) impedance. This c an be achieved by connecting a large surface area of the cabinet to earth, for example by mounting the FC motor on a conductive rear plate.

Especially when having long distances between the stations in a PROFIBUS network it can be necessary to use additional potential equalizing cables, connecting the individual stations to the same earth potential.

Profibus DP

■DP communication relations

Communication according to PROFIBUS DP, i.e. EN 50170 part 3, is supported. Consequently a master that supports PROFIBUS DP must be used.

By DP communication one of the parameter-process

data objects (PPO’s) described below must be used.

■PPO description

A special feature of the PROFIBUS Profile for frequency converters is the communication object called a PPO,

meaning Parameter-Process Data Object.

The PPO is well suited for fast cyclical data transfer, and may, as the name implies, carry both process data and parameters.

The selection of PPO type is made according to the master configuration.

A PPO may consist of a parameter part and process data part. The parameter part can be used for reading and/or updating the parameters one by one. The process data part consists of a fixed part (4 bytes) and a parametrable part (8 or 16 bytes). In the fixed part control word and speed reference are transfered to the frequency converter while status word and actual output frequency feedback are transfered from the frequency converter. In the parametrable part the user chooses which parameters ha ve to be transfered to (parameter 915) and which from (parameter 916) the frequency converter.

■PCA handling

The PCA portion of the PPO types 1, 2 and 5 will handle a number of tasks. The master may control and supervise parameters and request a response from the slave, while the slave, apart from responding to a request from the master may transmit a s pontaneous message.

Requests and responses is a handshake procedure

and cannot be batched, m eaning that if the master

sends out a Read/write request, it has to wait for the

response, before it sends a new request. The request or response data value will be limited to max. 4 bytes, which implies that text strings are not transferable. For

further information, please see section Examples .

Request/response handling

The RC portion of the PCA word defines the requests that may be issued from the master to the slave as well as what other portions of the PCV (IND and PVA) are involved.

The PVA portion will transmit word-size parameter values in bytes 7 and 8, while long word size valuesrequirebytes5to8(32bits).

If the R esponse / Request contains array elements, the IND will carry the A rray Subindex. If parameter descriptions are involved, the IND will hold the Record Subindex of the Parameter description.

■Spontaneous messages

The S pontaneous message is activated by the active parameters i.e. 538, 540, or 953 and will be carried with the PCV response, stating PNU and PVA of the changed active parameter that triggered the message.

Spontaneous messages are generated when the value is changed in one of the abovementioned parameters. It means that a message will be sent when a warning comes, and when a warning disappears.

Simultaneously the frequency converter will toggle the

SPM bit (11) of PCA word (see section PCA handling).

The Spontaneous messages will be transmitted until the master has acknowledged reception of the message by changing the SPM bit.

NB!:

Spontaneous messages are only active when parameter 917 is "ON"!

Example of SPM execution

In the frequency converter the SPMs are temporarily stored in a FIFO buffer. This means that up to 16 consecutive SPMs can be retained. If only one SPM has entered the FIFO, the frequency converter will resume normal communication as soon as the SPM has been ack nowledged by the master (and the condition causing the SPM been rectified). If more SPMs are in the FIFO, these will be transmitted consecutively upon acknowledgement. If more SPMs are triggered when the FIFO is full, these will be ignored.

■Synchronize and freeze

The control commands SYNC/UNSYNC and FREEZE/UNFREEZE are broadcast functions. SYNC/UNSYNC is used to send syncronized control commands and/or speed reference to all the connected slaves (FCM 300/FCD 300/VLT 2800 Series). FREEZE/UNFREEZE is used to freeze the status feedback in the slaves to get syncronized feedback from all connected slaves.

The synchronize and freeze commands only affect Process Data (the PCD part of the PPO).

SYNC/UNSYNC

SYNC/UNSYNC can be used to obtain simultaneous reactions in several slaves, for exa mple synchronised start, stop or speed change. A SYNC command will freeze the actual control word and speed reference, incoming Process Data will b e stored but not used until a new SYNC command or a UNSYNC command is received.

See the example below where the left column holds the speed reference send out by the master and the three right columns hold the actual speed reference used in each of the three slaves.

FREEZE/UNFREEZE

FREEZE/UNFREEZE can be used to get simultaneous reading of Process Data for example output current from several slav

es. A FREEZE command will freeze the current actual values and on request the slave will send back the value that was present when the FREEZE comm

and was received. The actual

values will be update

d when a new FREEZE or UNFREEZE command is received. See the example below where the left column holds the current

values read by the master and the three right columns hold the actual output current of the three slaves.

■Clear Mode / Fail Safe

If the PLC/Master functions are seriously disturbed, the DP master will go into Clear Mode. The Drive can be programmed to react in various ways on that incident. Theseoptionsareshowninthetablebelow. The drives which support the DP V1 features, basically support the Fail Safe function for Clear Mode as stated in the GSD attribute Fail_safe = 1. Fail Safe means, that the slaves safely detect a clear state of the maste r. The reaction however must be programmed as shown in the table below.

For masters, that do not support Fails Safe Clear, the drive will have the same reaction on a clear mode as for Fail Safe Clear. If a Clear appears, the control word and speed reference is set to zero in the drive. The reaction of the drive, however depends on the setting of parameter 805 (control word validity) and parameter 804 (Time Out function).

P804 P805 Drive Behaviour on Clear mode Off Bit 10 = 1, Control Word valid The drive will continue with the previous send valid

Control word and speed reference

Off Bit 10 = 0, Control Word valid The Drinve Control Word and Speed Reference will

be set to zero, which will cause the drive to stop.

Off No function: Control Word always valid The Drinve Control Word and Speed Reference will

be set to zero, which will cause the drive to stop.

<>Off Bit 10 = 1, Control Word valid The drive will continue with the previous send valid

Control word and speed reference until the timer programmed in P 803 expires. After that the drive will do the action programmed in P 804.

The drive leaves the Clear Reaction STate when the master sends process data values <> 0.

NB!:

The behaviour, which is described in the first line is the factory setting. In critical applications

a time out function can be used. In case of clear mode, the drive is working as described in the selection of parameter 805.

PCA part (byte 1-2) The RC part tells what the PCV part must be used for. The functions available appear

from the table, see section PCA handling.

When a parameter is to be changed, choose value 2 or 3, in this example 3 is chosen, because parameter 207 covers a long word (32 bits).

SPM bit:

The function is explained in section Spontaneous messages, in the example the function Spontaneous

Messages is not applied (parameter 917 = OFF), therefore SPM is set for 0. PNU = Parameter number: Parameter number is set for: 207 = CF Hex. This means that the value of the PCA part is 30CF Hex.

IND (bytes 3-4): Used when reading/changing parameters with subindex, for example parameter 915. In the example bytes 3 and 4 are set to 00 Hex.

PVA (bytes 5-8): The data value of parameter 207 must be changed to 10.00 seconds. The value transmitted must be 1000, because the conversion index for parameter 207 is -2, this means that the value received by the frequency converter is divided by 100, making the frequency converter perceive 1000 as 10.00. Bytes 5-8 = 1000 = 03E8 Hex.

PCD CTW according to Profidrive profile:

Control words consisting of 16 bi

ts, the meaning of

the various bits appears from the table, see section

Control word/Status word. The following bit pattern

sets all neces sary start com

mands: 0000 0100 0111 1111 = 047F Hex.* 0000 0100 0111 1110 = 047E Hex.* 0000 0100 0111 1111 = 047F Hex

. Quickstop: 0000 0100 0110 1111 = 046F Hex. Stop: 0000 0100 0011 1111 = 043F Hex. * For restart after power up: Tr

ip OFF 2 and 3.

MRV:

Speed reference, the data format is "Standardized value". 0 Hex = 0% and 4000 Hex = 100%.

In the example 2000 Hex is used corresponding to 50% of maximum frequency

(parameter 202).

The whole PPO therefore

gets the following value in Hex:

The Process data within the PCD part is acting on the frequency converter immediately, and can be updated from the master as quickly as possible.

The PCV part is a "hand shake" procedure which means that the frequency converter has to acknowledge the command, before a new one can be written.

- A positive response of the above example may look like this:

The PCD part responds according to the state and parametration of the frequency converter.

The PCV part responds as: PCA: As the request telegram, but here the RC part is taken from the

response table s ee section PCA handling.In

this example RC is 2Hex, which is a confirmation that a parameter value of the type long word (32 bit) has been transferred.

IND is not used in this example.

PVA: 03E8Hex in the PVA part tells that the value of the parameter in question (207) is 1000 which corresponds to 10.00.

STW: 0F07 Hex means that the motor is running and there are no warnings or faults (for details see

Status word table in section Status word).

MAV: 2000 Hex tells that the output frequency is 50% of max. frequency.

- A negative response may look like this:

Byte Value PCA 1 70 PCA 2 00 IND 3 0 0 IND 4 0 0 PVA 5 00 PVA 6 00 PVA 7 00

PCV

PVA 8 02 STW 9 0F STW 10 07 MAV 11 20

PCD

MAV 12 00

RC is 7 Hex which means that the request has been rejected, and the fault number can be found in the PVA part. In this case the fault number is 2 which means that the upper or lower limit of the parame ter is exceeded.

■DP V1 Identifications

The V1 functionalities require a GSD file supporting V1. Of compatibility reasons in general the V1 versions got the same DP ident number as the corresponding V0 version. This means, that a V1 unit

can replace a V0 unit without changing the master configuration. The table shows the available GSD files for FCM 300/FCD3 00/VLT 2800. GSD files are placed on http://www.danfoss.com/drives.

Please note, that some parameters might not be active in all products.

Special attention must be given to the following parameters that are not described in this manual:

- 502- 508: Selection of how to gate PROFIBUS control commands with control commands on the digital i nputs of the FCM 300/FCD 300/VLT2800.

- 512: Control word profile, selects a control word according to profidrive or a Danfoss specified control word.

- 515 - 543: Data readout parameters that can be used to read various actual data from the frequency converter, as for example actual status on the analog and digital inputs of the FCM 300/FCD 300/VLT 2800 thus using these as inputs to the master.

■PROFIBUS specific parameters

800 Protocol select

(PROTO COL SELECT)

Value:

✭PROFIBUS DP V1

[30]

Function:

Selection of the PRO FIBUS protocol supported by the master.

Description of choice:

DP: Communication according to EN 50170, part 3

NB!:

In the event of an update of parameter 800, even with an unchanged data value, the PROFIBUS

option is initializ ed , which means that all communication parameters 801, 802, ..., e.g. slave address, baud rate, PPO type etc., are being updated.

803 Bustimeout

(BUS TIME OUT)

Value:

1-99sec.

✭ 1 sec.

804 Bus time out function

(TIME OUT FUNCT.)

Value:

✭Off (OFF)

[0]

Freeze output frequency (FREEZE OUTPUT)

[1]

Stop with auto restart (STOP)

[2]

Output frequency = JOG freq. (JOGGING )

[3]

Output freq. = Max. freq. (MAX SPEED)

[4]

Stop with trip (STOP AND TRIP)

[5] No comm. option control (NO COMM OPT CONTROL)

[6] Select setup 4 (SELECT SET UP 4)

[7] Select setup 2

[8]

Function:

The time out counter is triggered at the first reception of a valid control word i.e. bit 10 = ok, when DP is used.

The time out function can be activated in

two different ways:

1. CTW is not updated within the time specified in parameter 803.

2. Time out is triggered if the CTW is not valid, see p arameter 805.

The FCM 300/FCD 300/VLT 2800 remains in time out state until one of the following conditions is true:

1. Valid control word (Bit 10 = ok) is received. If Stop with trip is selected, reset must also be activated. If

Select setup 2 is selected, the FCM 300/FCD 300 / VLT 2800 will remain in Setup 2 until parameter 4 is changed.

2. Parame ter 804 = Off Þ control via PROFIBUS is resumed and the most recent control word is used.

Description of choice:

- 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 run at

JOG frequency until communication is resumed.

- Output frequency = Max. freq.: Motor will run at

max. frequency until communication is resumed.

- Stop with trip: Motor is stopped, reset needed

for restart, see explanation above.

- No communication option control: enable the process control via the serial port or digital input.

- Select setup 4

- Select setup 2.

805 Function of control word bit 10

(BIT 10 FUNCTION)

Value:

No function (NO FUNCTION)

[0]

✭Bit 10 = 1 CTW active

(BIT 10 = 1 CTW ACTIVE)

[1]

Bit 10 = 0 CTW active (BIT 10 = 0 CTW ACTIVE)

[2]

Bit 10 = 0 time out (BIT 10 = 0 TIME OUT)

[3]

Function:

Control word and speed reference will be ignored if bit 10 of the control word is 0, b ut parameter 805 lets the user change the function of bit 10. This is some times necessary as some masters are setting all bits to 0 in various fault situations. In these cases it makes sense to change the function of bit 10 so that the FCM 300/FCD 300/VLT 2800 is commanded

to stop (coast) when all bits are 0.

Description of choice:

- Bit 10 = 1

CTW active: Control word and

speed reference is ignored if bit 10 = 0.

- Bit 10 = 0

CTW active: Control word and

speed reference is ignored if bit 10 = 1. If all bits of the control word are 0 the FCM 300/FCD 300/ VLT 2800 reaction will be coasting.

- Bit10=0

timeout: The time out function selected

in parameter 804 is activated w hen bit 10 is 0.

- No function: Bit 10 is ignored, i.e. control word

and speed reference is always valid.

■Read/write on frequency converter parameters

In an automation system, frequency converter parameters can be accessed either from the Process controller (i.e. PLC), or by various kinds of HMI equipment. In order not to interfere access from controllers and tools, the following should be taken into consideration: Parameter access in the drive is performed in two logical parameter channels, which can be individally programmed to access a certain parameter setup via parameters 005 Programming Setup and 970 Parameter setup selection. This means, that before writing or reading to a parameter in a certain frequency converter set-up from a PLC, the parameter 970 must bne set to the desired set-up. For access from HMI equipment, the access is controlled by parameter 005. The figure below shows this behaviour, and the possible sources of the two logical parameter channels.

VLT frequency converter

ccess from process

control e.g. PLC:

- P CV channel (DP Vo)

-MSAC Master Class 1

ccess from HMI:

- Local Control Panel

- FC standard interface

- MSAC Master class 2

Please note, that even thoug h these two logical parameter channels are separated, data conflict can occour, if write on parameters is made from a HMI unit into a s e t-u p which is actively used by the frequency converterorusedbytheprocesscontroller(e.g. PLC).

NB!:

For backward compability reasons the following behaviour must be observed:

A Read or Write on parameter 970 via the MSAC master class 2 connection will be accepted, but the value will internally be read /written to parameter 005.

A Read or Write on parameter 005 via the process controller channel will be accepted, but the value will internally be read/written to parameter 970.

For parameter store, the following should be observed:

A Write command to a frequency converter parameter via the MSAC Master class 2 connection will be stored in RAM and in Non Volatile Memory. Please note, that continuous writing to frequency converter parameters via the MSAC Master class 2 connection should be avoided in order not to damage the Non Volatile Memory.

A Write command to a frequency converter parameter via the Process Control channel will b e stored in RAM only. Store in Non Volatile Memory is possible by writing a store command to parameter 971 Save data values, which will result in store of the entire set-up in NVRAM.

The table below shows how data write from various sources are stored in the frequency converter:

FCM 300 / FCD 300 / VLT®2800 / DP V1 PROFIBUS

Warnings and alarm

messages

■Warning and alarm messages

There is a clear distinction between alarms and warnings. In the case of an alarm, the FCM 300/FCD 300/VLT 2800 will enter a fault condition. After the cause for the alarm has been cleared, the master will have to acknowledge the alarm message for the FCM 300/FCD 300/VLT 2800 to start operating again. A warning, on the other hand may come when a warning condition appears, and disappear when conditions return to normal without interfering with the process.

Warnings

Any warning within the FCM 3 00/FCD 300/VLT 2800 is represented by a single bit within a war ning word. A warning word is always an active parameter. Bit status FALSE [0] means no warning, while bit status TRUE [1] means warning.

Any bit change in the warning word will result in a Spontaneous message being issued.

In addition to the warning word message the master will also be notified through a change of bit 7 in the Status Word.

Alarms

Following an Alarm message the FCM 300/FCD 300/VLT 2800 will enter Fault condition. Only after the fault has been alleviated and the master has acknowledged the alarm message by setting bit 7 in the Control word, can the FCM 300/FCD 300/VLT 2800 resume operation.

Any alarm within the FCM 300/FCD 300/VLT 2800 is represented by a single bit within an alarm word. An alarm word is always an action parameter. Bit status FALSE [0] means no fault, while bit status TRU E [1] means fault.

Any bit change in the alarm word wil l result in a Spontaneous message being issued.

■Spontaneous messages

If a fault or warning condition should occur, the FCM 300/FCD 300/VLT 2800 will, if the proper communicative relationship has b ee n established, issue a Spontaneous message to communication partners.

Instead of responding to the master’s request, the FCM

300/FCD 300/VLT 2800 will exchange the requested response with the alarm or the warning message.

Warnings and alarms will trigger a Spontaneous message. The same is true with any change to an active parameter.

■Warning word, extended Status word and

Alarm word

Warning word, extened status word and alarm word are shown on the display in Hex format. If there are more than one war ning or alarm, a sum of all warnings or alarms will be shown. Warning word, extened status word and alarm word can also be displayed using the serial bus in parameter 540, 541 and 538.

Station

address

■Station address

The station address of slave can be selected via

- Hardware switch (only FCD 300)

- Parameter 918 via bus or LCP2

- Command "Set Station Address" of Profibus DP

Theaddressviathehardwareswitchisvalid,if the switch is set between 0-125. All selections via parameter 918 or "Set Station Address" command will be rejected. The address setting will only be effective at power up. Changing during run time willbeeffectiveatnextpowerup.

The setting of address via parameter 918 is possible, if the hardware switch is set to 126 or 127 (factory setting). A new address is effective at a new power up.

The setting of the address via the "Set Station Address" command is possible, if the hardware switch is set to 126 or 127 (factory setting). By the "Set Station Address" command it is possible to lock the programmed address, which makes it impossible to change the address by this command. The address setting will be unlocked, if the parameter 918 or the address switch is changed followed by a power cycle.

■Extended Diagnosis

By the extended diagnose fu n ction it is possible to receive alarm and warning information from the

frequency converter. The setting of parameter 849 determines which frequency converter events should trigger the extended diagnose function.

If parameter 849 is set to Disable [0], no extended diagnose data is sent regardless wether they appear in the frequency converter. If parameter 849 is set to Alarms [1], extended diagnose data is sent, if one or more alarms arrive in the Alarm parameters 538 or 953. If parameter 849 is set to Alarms/Warnings [2], extended diagnose data is sent if one or more alarms/warnings arrive in the Alarm parameters 538 or 953 or the warning parameter 540.

The sequence of an extended diagnose is as follows: If an Alarm or warning appears, the frequency converter will indicate that to the master by sending a high prior message via the output data telegram. This will cause the master to ask the frequency converter for extended diagnose inform ation, which will be replied by the frequency converter. When the Alarm/warnin g disappears, the frequency converter will again indicate that to the master, a nd on the following request from the master, return a standard DP diagnose frame (6 bytes).

The extended diagnose frame has the following content:

Byte Content Description
