Danfoss VLT 5000 Series Design Guide

Name (index 6):
The Name returns a string value in ASCII format, con-
taining the name of the parameter.
Example:
In this example the master reads the name of param-
eter 001, Language.
The following telegram must be sent to the frequency
converter:
STX LGE ADR PKE IND PWE
HIGH
PWE
LOW
PCD1 PCD2 BCC
02 0E 01 40 01 00 06 00 00 00 00 XX XX XX XX XX
STX = 02 Start byte
LGE = 0E Length of remaining telegram
ADR = Sends the frequency converter on Address
1, Danfoss format
PKE =
4001; 4 in the PKE field indicates a Read
Parameter Description and 01 indicates pa-
rameter number 001, Language
IND =
0006; 6 indicates that Names is required.
The response from the frequency converter will be:
STX LGE ADR PKE IND PVA PCD1 PCD2 BCC
02 12 01 30 01 00 06 4C41 4E47 5541 4745 XXXX XXXX XX
PKE =
3001; 3 are the response for Name and 01
indicates the parameter number 001, Lan-
guage
IND =
00 06; 06 indicates that Name is sent.
PVA = 4C 41 4E 47 55 41 47 45
L A N G U A G E
The parameter value channel is now set up to a visible
string which returns an ASCII character for each letter
in the parameter name.
Lower limit (index 7):
The Lower limit returns the minimum allowed value of
a parameter. The data type of Lower limit is the same
as for the parameter itself.
Upper limit (index 8):
The Upper limit returns the maximum allowed value of
a parameter. The data type of Upper limit is the same
is for the parameter itself.
Default value (index 20):
The Default value returns the default value of a pa-
rameter, which is the factory setting. The data type of
Default value is the same as for the parameter itself.
Additional characteristics (index 21):
The command can be used for getting some additional
information on a parameter, eg. No bus Access, Power
Unit dependency, etc.. The Additional characteristics
returns an answer in PWE
LOW
. If a bit is logic '1', the
condition is true according to the table below:
Bit Description
0 Special Default Value
1 Special Upper Limit
2 Special Lower Limit
7 LCP Access LSB
8 LCP Access MSB
9 NoBusAccess
10 Std Bus Read Only
11 Profibus Read Only
13 ChangeRunning
15 PowerUnitDependency
If one of bit 0 Special Default Value, bit 1 Special Upper
Limit and bit 2 Special Lower Limit are true, the param-
eter has power unit depending values.
Bit 7 and 8 indicates the attributes for the LCP access,
see table.
Bit 8 Bit 7 Description
0 0 No access
0 1 Read only
1 0 Read/write
1 1 Write with lock
Bit 9 indicates No bus Access.
Bits 10 and 11 indicates that this parameter can only
be read over the bus.
If bit 13 is true, the parameter cannot be changed while
running.
If bit 15 is true, the parameter is depending on the
power unit.
