Danfoss VLT 5000 Podręcznik
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.
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.
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.

P22 Input 201E:
Shows the actual reference from the VLT frequency
converter.
P22 Output 2000 Hex:
Here you can write a reference to the 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.
