Parameterization of LinMot servo drives over fieldbus interfaces / 30.06.2016
LinMot Drive Configuration over Fieldbus
Beside the actual RAM and ROM value each parameter has its
default value. The default value is displayed in the detailed parameter
view of the LinMot-Talk software.
During firmware installation the ROM values are set to the default
values of the corresponding parameters.
E1100 drives provide resetting the parameters to their default values
over fieldbus interfaces. Resetting to default value is possible for
single parameters (via UPID) or for all parameters of any firmware
layer at once (see below).
NOTE: B1100 do not support this feature, because the default values
are not stored on the drive.
The whole configuration consists of parameters of different types (bit,
byte, 16bit integer, 32bit integer and string parameters). In order to
keep the interface as simple as possible any parameter can be
accessed as a 32bit integer value. The drive's operating system will
filter out the relevant number of bits for each parameter.
Since string parameters can be longer than 4 characters (= 4 Bytes),
a single 32bit integer value is not sufficient to define a general string.
Therefore strings are handled in a special way:
-
In the LinMot-Talk software to each string parameter one single
UPID is shown.
-
Internally the string is split into parts (so called 'stringlets') of 4
characters (= 4 bytes = 32 bits).
-
Each stringlet has its own UPID.
-
For E1100 drives: The UPID of the first stringlet is the string UPID
plus 1, the UPID of the second stringlet is the string UPID plus 2
and so on.
For B1100 drives: The UPID of the first stringlet is the string UPID
-
itself, the UPID of the second stringlet is the string UPID plus 1
and so on.
The following example shows the principle of converting strings to
raw data values.
