■ About this manual
This manual is intended to be used both as an
instructional and as a reference manual. It only briefly
touches on the basics of the PROFIBUS protocol
whenever it is necessary for gaining an understanding
of the PROFIDRIVE implementation of the PROFIBUS
Profile for Variable Speed Drives (VDI/VDE 3689) and
the DANFOSS PROFIBUS for the FC motor and the
VLT 2800.
The manual is also intended to serve as a guideline
when you specify and optimize your communication
system.
If you are not completely familiar with PROFIBUS or
the Profile for Variable Speed Drives, it may be
advisable to read some of the material provided on
these subjects, eg DIN 19245 parts 1 and 3 and VDI/
VDE 3689.
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.
Introduction
■ Assumptions
This manual assumes that you are using a DANFOSS
FCM 300 and VLT 2800 with 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, and that all
requirements stipulated in the PROFIBUS standard as
well as those set up in the PROFIBUS Variable Speed
Drives Profile and its company-specific
implementation PROFIDRIVE, as well as those
pertaining to the VLT Variable Speed Drive are strictly
observed as well as all limitations therein fully
respected.
■ 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 nonDanfoss slave, the appropriate manuals should be
consulted.

Programming: See the design guide:
FC motor (MG.03.Bx.02)
VLT 2800 (MG.28.Ex.02)
for descriptions on how to programme the ordinary
FC motor and VLT 2800.
Quick Setup
■ General information
Parameter 918:
Set the station address, - one unique address per
unit.
In parameters 502-508 it is possible to define how to
gate the control commands from the PROFIBUS with
the equivalent control commands of the digital inputs.
The FC motor/VLT 2800 adjusts to the baudrate and
the configuration from the master.
Communication is established by setting the
parameters stated below.
Setting up the master: See the manual on the master
as well as the chapters of this manual giving details
on the PROFIBUS interface for information on how to
set up the master.

■ Master controlled Variable Speed Drives (VSD)
The PROFIBUS Field-bus was designed to give you
unprecedented flexibility and command over your
VSD controlled system. The PROFIBUS will perform
as an integrated part of your VLT VSD, giving you
access to all parameters relevant to your application.
The VSD 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 VSD acknowledges receipt by
transmitting status signals, such as running, on
reference, motor stopped and so on to the master.
The VSD may also transmit fault indications, alarms
and warnings to the master, such as Overcurrent or
Phaseloss.
The PROFIBUS communicates according to the
PROFIBUS Protocol Standard DIN 19245 parts 1 and
3. This means that it can communicate with all
masters that comply with this standard, but it does
not necessarily mean that all services available in the
PROFIBUS standard are supported. The VDI / VDE
3689 PROFIBUS Profile for Variable Speed Drives is a
subset of PROFIBUS which only supports the
services relevant to speed control applications.
PROFIDRIVE is an implementation of VDI / VDE 3689
profile created by DANFOSS and a number of other
companies.
Communication partners
In a control system the VSD 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.
■ Physical layer
The field of application of a field-bus system is
primarily determined by the transmission media and
the physical bus interface selected. The type of bus
cable required for the application and its installation
(physical layer) are particularly important factors, in
addition to the required transmission reliability of the
physical level.
Though a fundamental feature of the PROFIBUS standard is the possibility of specifying several different
physical interfaces, the standard, at the time of
printing, has allowed for one universal specification
only, namely the EIA Standard RS 485-A, which has
found acceptance both in the field of factory automation and in several areas of the processing industry.
The PROFIBUS Interface
■ 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
length. The table below shows the maximum allowed
cable length and maximum number of nodes/VLT’s
with 1, 2, 3 and 4 bus segments.
Max. total bus cable lenght
1 segment: 2 segments: 3 segments: 4 segments:
32 nodes 64 nodes 96 nodes 128 nodes

1.5 MBaud 200 400 600 800
3 MBaud 100 200 300 400
Note that a repeater is a node in both of the two
segments it connects. The number of VLT is based on
a single master system. If there are more masters the
number of VLT 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).
EMC precautions
The following EMC precautions are recommended to
obtain interference free operation of the PROFIBUS
network. Additional information on EMC can be found
in the design guide on the FC motor (MG.03.Bx.02).
Please also consult the manual of the PROFIBUS
master for further installation guidelines.
If the PROFIBUS cable has to cross a motor and
brake resistor cable they must cross each other at
an angle of 90°.
- 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 FC motor Series is provided with different
clamps and brackets to enable a proper ground
connection of the PROFIBUS cable screen. The
screen connection is shown in the following
drawing.
Relevant national and local regulations, for
example regarding protective earth
connection, must be observed.
- Cable routing
The PROFIBUS 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 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.
- 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 can 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.

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 PROFIBUS is provided with a suitable
termination which may be activated by the
switches of the RS485 switch block located
just to the left of the terminal block X100 (see
drawing below). The switches should be on to
terminate the bus.
The switches should never be left in opposite
positions. They should either both be ON or
both be OFF!
- Most masters and repeaters are equipped with
their own termination.
- If an external termination circuit consisting of three
resistors is connected to the bus line a 5 V d.c.
power supply must be used, please note that this
must be galvanically isolated from the a.c. line.

4. New setpoint transfer
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 reduce the
system response).
This could also be the case where control loops are
closed over the bus.
As a very fast alternative it is of course possible to
close the control loop outside the bus.

System layout
Closing the control loop outside the fieldbus

Rapid Cyclical transmission with PPO using DP
Parameter up-/downloads can be achieved by using
the so-called Parameter / Process Objects - PPOs of 12, 20 or 28 bytes length as specified in the VDI/
VDE 3689 profile, see drawing page 16.
This procedure, however, occupies 8 bytes additional
I/O memory space in the PLC bytes per slave, and
slows down the system (see also “Timing” page 15).
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.
■ Features and services supported by FC motor
and the VLT 2800
Features available as described by the unit
classification
The unit classification as layed out in the PROFIBUS
Profile for VSDs describes the functionality of the unit.
There are 4 classes where class 1 signifies the lowest
performance class, and class 4 the highest.
The FC motor / VLT 2800 is a class 3 unit except for
the following features:
- Fault buffer
- Change access rights for parameter write
- Change access rights for process control
- Time difference
- Hardware configuration ident.
The FC motor / VLT 2800 complies with the following
class 4 features:
- Baudrate > 500 kBaud
- Programmable content of PCD 3 through 6 (10) of
the PPO’s
- PPO type 5

■■
■ FC motor / VLT 2800 response time
■■
The update time via the PROFIBUS 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 (FC
motor / VLT 2800 with PROFIBUS), and 2) the
internal update time, which is the time it takes to
transmit data between the FC motor / VLT 2800
control card and the PROFIBUS.
Communication time (t
) depends on the actual
com
transmission speed (baudrate) and the type of master
in use. The minimum obtainable communication time
with the FC motor / VLT 2800 with PROFIBUS is
approx. 100 µsec 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
) depends on the type of
int
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.

■ DP communication relations
DP
Communication according to PROFIBUS DP, i.e. DIN
19245 part 1 & 3, is supported. Consequently a
master that supports PROFIBUS DP must be used.
■ PPO description
A special feature of the PROFIBUS Profile for VSD’s 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 request.
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.
PPO. Parameter-Process Data Object
By DP one of the following shown PPO’s must be used:
By DP communication one of the parameter-process
data objects (PPO’s) described below must be used.
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 VLT while status word and actual
output frequency feedback are transfered from the
VLT. In the parametrable part the user chooses which
parameters have to be transfered to (parameter 915)
and which from (parameter 916) the VLT.
Type 1, 2 and 5 consist of the parameter part and 4,
12 and 20 byte process data, respectively.
Type 3 and 4 consist of 4 and 12 byte process data,
respectively.

■ 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
spontaneous message.
Requests and responses is a handshake procedure
and cannot be batched, meaning 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.

■ Spontaneous messages
The Spontaneous 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 VLT will toggle the SPM bit (11) of
PCA word (see “PCA handling” page 17).
Bit sequence
16 boolean values for control and presentation of user
functions. Notation is binary.
Bit 87654321
Byte 1 15 14 13 12 11 10 9 8
Byte 2 7 6 5 4 3 2 1 0
The Spontaneous messages will be transmitted until
the master has acknowledged reception of the
message by changing the SPM bit.
Spontaneous messages are only active when
parameter 917 is “ON”!

Example of SPM execution
DP
In the VLT 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 VLT will resume normal communication as
soon as the SPM has been acknowledged 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 (FC motor Series/VLT 2800 Series).
FREEZE/UNFREEZE is used to freeze the status
feedback in the slaves to get syncronized feedback
SYNC/UNSYNC
SYNC/UNSYNC can be used to obtain simultaneous
reactions in several slaves, for example synchronised
start, stop or speed change. A SYNC command will
freeze the actual control word and speed reference,
incoming Process Data will be stored but not used
until a new SYNC command or a UNSYNC command
is received.

FREEZE/UNFREEZE
FREEZE/UNFREEZE can be used to get simultaneous
reading of Process Data for example output current
from several slaves. 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 command was received. The actual values
will be updated when a new FREEZE or UNFREEZE
command is received.

PCA part (byte 1-2)
The R
C part tells what the PCV part must be used for.
The functions available appear from the table, page
17.
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 on page 19, 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 for 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 VLT is
divided by 100, making VLT perceive 1000 as 10.00.
Bytes 5-8 = 1000 = 03E8 Hex.

The PCD part responds according to the state and
parametration of the VLT.
The PCV part responds as:
PCA: As the request telegram, but here the RC part is
taken from the response table on page 16. 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 on page 22).
MAV: 2000 Hex tells that the output frequency is 50%
of max. frequency.
The PCV part is a “hand shake” procedure which
means that the VLT has to acknowledge the
command, before a new one can be written.

■ FC motor and VLT 2800 parameters
Only the PROFIBUS specific parameters (800 - 805
and 904 . . ) are described in this manual. All other
parameters and their functions are unaffected by the
PROFIBUS option. We refer to the parameter
Parameters
description in the design guide on the FC motor
Series (MG.03.Bx.02) and the design guide on the
VLT 2800 Series (MG.28.Ex.02).
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 inputs of the
FC motor / 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 VLT, as for example actual status
on the analog and digital inputs of the
FC motor / VLT 2800 thus using these
as inputs to the master.
■ PROFIBUS specific parameters
800 Protocol select (PROTOCOL SELECT)
✭ DP [1]
804 Bus time out function (TIME OUT FUNCT.)
Selection:
✭ 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]
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
parameter 805.
The FC motor / 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 FC motor / VLT
2800 will remain in Setup 2 until parameter 4 is
changed.
2. Parameter 804 = Off ⇒ control via PROFIBUS is
resumed and the most recent control word is
used.
Function:
Selection of the PROFIBUS protocol supported by the
master.
Description of selections:
-DP: Communication according to DIN 19245 part
3.
Updating parameter 800, even with an
unchanged data value, will initialise the
PROFIBUS option, meaning that all
communication parameters such as slave addresses,
PPO type etc. will be updated.
803 Bus time out (BUS TIME OUT)
Selection:
✭ 1 - 99sec 1 sec
✭ Factory setting
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 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.
- Select setup 2.

805 Function of control word bit 10
(Bit 10 function)
Selection:
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:
According to the PROFIDRIVE profile, control word
and speed reference will be ignored if bit 10 of the
control word is 0, but 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 FC motor/
VLT 2800 is commanded to stop (coast) when all bits
are 0.
Description of selections:
- Bit 10 = 1 ⇒ CTW active: Control word and speed
reference is ignored if bit 10 = 0.
- Bit 10 = 0
reference is ignored if bit 10 = 1. If all bits of the
control word are 0 the FC motor / VLT 2800
reaction will be coasting.
- Bit 10 = 0
selected in parameter 804 is activated when bit 10
is 0.
- No function: Bit 10 is ignored, i.e. control word
and speed reference is always valid.

■ Warning and alarm messages
There is a clear distinction between alarms and
warnings. In the case of an alarm, the FC motor / 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 FC motor /
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 FC motor / VLT 2800 is
represented by a single bit within a warning 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.
■ Spontaneous messages
If a fault or warning condition should occur, the FC
motor / VLT 2800 will, if the proper communicative
relationship has been established, issue a
Spontaneous message to communication partners.
Instead of responding to the master’s request, the FC
motor / 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 and alarm messages
Alarms
Following an Alarm message the FC motor / 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 FC motor /VLT 2800 resume operation.
Any alarm within the FC motor / 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 TRUE [1]
means fault.
Any bit change in the alarm word will result in a
Spontaneous message being issued.
