■Configuring of the CMD and VLT 5000
The first step is to connect all Interbus slaves to the
master and power up all units.
Start the IBS CMD software and choose a new
project from File and New.
The screen should now look like this:
Next step is to read the slaves on the bus system.
Click on Configuration frame and click on the right
mouse button. Select Read In and choose Startup
without PDP.
The state will be changed from Offline to Online
when the Read In is finished. Please look at the
bottom of the screen.
After the Read In, CMD will indicate each VLT
frequency converter with a DriveCom symbol, a
station number and an ID number.
Next step is to configuring the Interbus system. This
is done by clicking on the VLT symbol and pressing
the right mouse button. Select Description.
Here you can type a Station name, Device name
and a Device number.
Click on Parameter Channel.
By message lenght transmit and receive enter 246
Byte and select Get-OD (long format). The message
length now corresponds to the internal buffer in the
VLT frequency converter. Get-OD (long format)
means that the master will read the English
parameter description text from the VLT frequency
converter.
Press OK twice.

The VLT frequency converter is now set up and the
program can be downloaded to the PLC master.
This is done by clicking with the right mouse button
on the Controller board.
Select Parameterization and Execute.
After the parameterization is done, the master will
start to run. If you are using a Siemens S7 or S5
master, the LCD will look like this:

■Drivecom profile
VLT 5000 has implemented the Drivecom profile in
the Interbus software. In order to be able to run with
the Drivecom profile, VLT parameter 512 Telegram
profile must be set to Fieldbus option.
If you change the operating state from Online to
Monitor you can write the control word and refe-
rence to the VLT frequency converter. In Monitor
state you can also read and write to parameters.
Now you can start the built in Drivecom monitor in
CMD by clicking on the Controller board and clicking
on the right mouse button. Select Drivecom.
The Drivecom monitor will now show Danfoss, VLT
5000, Profile: 21, in the upper left corner.
The Drivecom monitor is spilt up in three parts:
Analog Display, Control Word and Status word.
In the Analog Display part you can set a reference
and in the Control word part you can start and stop
the VLT frequency converter. In the Status word
part you can see the actual status word from the
VLT frequency converter.

■Drivecom profile, cont.
By clicking Settings you can setup the Drivecom
monitor.
In Manufactured Specific Control bits Danfoss have
choosen to implement Jog, Setup select and
Reversering, and in Manufactured Specific Status
the Running Status bit is implemented.
Press OK when the Monitor settings are done.
Click on Device Control for controlling the VLT
frequency converter. Please notice that the control
word will change when you change the states.
The control word is now 7F Hex. Press Close.
The Manufactured Specific bits are now added to
the Drivecom monitor.
Type a reference in rpm below Set Speed and click
on Write to send the reference to the VLT frequency
converter. The rpm value can now be seen in the
VLT display as a reference from 0 - 100 %.
Click 4 for Ready to Switch On and click 2 for
Switch On.
By Clicking 5 the VLT frequency converter should
start the motor. Do not forget to set VLT parameter
502 Coasting to Bus.

■PCP communication
Via the CMD tool you are able to read and write to
parameters and read the English parameter text of
each parameter.
To start PCP communication you must be in Monitor
state. Click on the station number and click on the
right mouse button and choose Device
Parametization.
The dialog box will now show Danfoss, VLT 5000,
Profile: 21. In order to be able to read in all
parameters in the VLT frequency converter select
Device and Read Parameter List. The CMD tool will
now start reading all parameters, this will take 3-4
minutes.
When all parameters have been read, CMD will
show the first parameter 55F1 Hex Language at the
first row.
55F1 Hex corresponds to 22001D. This means that
all VLT 5000 parameters simply can be accessed by
adding 22000Dto the VLT 5000 parameter. For
example if you want to write to parameter 207
Ramp up time 1 you must write to 22207D(56BF
Hex).
The CMD tool can only indicate parameters by
hexadecimal numbers.
If you want to change the value of parameter 207
Ramp up time 1 to 10 sec you must write 1000 in
column next to index 56BF Hex. You have to
enter 1000 because VLT parameter 207 has a
conversion index of -2 = 10-2.
Highlight the row by clicking on 60 and click on F5
Write Value. The ramp up time in parameter 207
has now been changed to 10 sec.
At the bottom of the parameter list the Interbus
Drivecom 21 objects are available. These objects
are not accessible via the LCP but only via Interbus
PCP communication.
Please have a look at the Interbus operating
instructions for further description of these objects.

■Process and PCD data
The process data is spilt up in two parts, a fixed 2
words data part for controlling the VLT frequency
converter and a flexible part, called PCD, that
can consist of 7 words.
For controlling the VLT 5000 you can select
between the FC profile or Drivecom profile (VLT
parameter 512).
Please have a look at the Interbus operating
instructions for further description of each profile.
PCD data is very useful if you need a constant
update of process parametersvariables, for
example motor current or torque.

■Programming example
The following example will show how to set up
process and PCD data.
The chosen profile is Drivecom profile and as PCD
data we will readout parameter 520 Motor current
and 518 Motor frequency. We will also write to
parameter 207 Ramp up time 1 as PCD data.
The data for the VLT frequency converter in our PLC
program starts at address 20. So we have to map
address 20 to the Interbus card in the VLT
frequency converter. This is done with the CMD
tool.
First we have to setup the VLT frequency converter
to run with two PCD‘s. This is done in the
respective parameter 807 PCD size select and
parameter 915/916 PCD config. write/read.
PCD 1 has to be set to read the motor current via
parameter 520. This is done by setting sub index 1
in parameter 916 PCD configuration read to 520.
PCD 2 has to be set to read parameter 518 Motor
frequency. Set sub index 2 to 518.
PCD 1 has to be set to write the ramp up time 1 via
parameter 207. This is done by setting sub index 1
in parameter 915 PCD Configuration write to 207.
In parameter 807 PCD size select you have to
assign the number of PCD‘s which the VLT
frequency converter is using.
Choose 2 WORDS [2] and power down the VLT
frequency converter. At next power up the PCD‘s
will be active.

To activate the new settings with PCD, the CMD
need to read the configuration from the VLT
frequency converter again.
The process data should start at address 20 and
this has to be assigned to the master and slave.
Click on controller board and select Process data.
The Process data should now be 64 bits, corre-
sponding to 4 words: control word, reference, PCD
1 and PCD 2.
The Address Monitor shows the I/O area.
P20 Input 0F07 Hex:
Shows the status word from the VLT frequency
converter.
P20 Output 047C Hex:
Here you can write the control word to the VLT
frequency converter.
See Configuring of the CMD and VLT 5000 for how
to parametize the system.
When the system is running, change the state to
Monitor.
Click on controller board and select Address
Monitor.
P22 Input 201E:
Shows the actual reference from the VLT frequency
converter.
P22 Output 2000 Hex:
Here you can write a reference tothe VLT frequency
converter.
P24 Input 008D Hex (PCD 1):
This I/O area shows the actual motor current in Hex
(parameter 520 Data readout: Motor current).
The value corresponds in decimal to 141. But as
Parameter 520 has a conversion index of -2 (see
Manual) the actual motor current is 1.41 Amp.
P24 Output 03E8 Hex (PCD 1):
The same I/O area as reading of motor current was
set up to write to parameter 207 Ramp up time 1.
03E8 hex corresponds to 10 sek in ramp up time as
this parameter has a conversion index of -2.
P26 Input 00FB Hex (PCD 2):
This I/O area shows the actual motor frequency in
Hex (parameter 518 Data readout: Frequency).
The value corresponds in decimal to 251. But as
Parameter 518 has a conversion index of -1 (see
Manual) the actual motor frequency is 25.1 Hz.
P26 Output 0000 Hex (PCD 2):
This output is not configurated.
