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 22001
D
. This means that
all VLT 5000 parameters simply can be accessed by
adding 22000
D
to the VLT 5000 parameter. For
example if you want to write to parameter 207
Ramp up time 1
you must write to 22207
D
(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.

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
