Parameterization of LinMot servo drives over fieldbus interfaces / 30.06.2016
LinMot Drive Configuration over Fieldbus
The parameter settings, curve profiles and command table of a
LinMot drive can be exported together with other data (parameters,
oscilloscope settings) as a configuration file (ending *.lmc) with the
LinMot-Talk software. The configuration file can then be imported to
other drives again under usage of the LinMot- Talk 4 software.
Some users of the LinMot servo systems want to store the parameter
setup and/or curves in their main machine controller (PLC, IPC) as a
simple value list. So they don't need any PC tools for configuration of
drives when they produce series of the same machine type or when
they have to replace a drive in the plant.
Beside the possibility of exporting configurations in LMC file format
the LinMot-Talk software allows to save the setup into a simple text
file. Data is stored in an easy interpretable comma separated value
format. The file has the extension *.pvl (Parameter Value List). A
simple parser can convert the text file data into the customer specific
data format.
Figure 12: Export Raw Data
The LinMot-Talk software offers selective export of configuration data:
If 'All Parameters' is selected, all parameters are listed in the export
file (hundreds of parameters, most of them are not used or set to their
default value)
If 'Changed Parameters' is selected, the resulting file will be much
smaller. Only parameters, which have been changed during the setup
process (and therefore are relevant for the application), are listed in
the file.
Only curves that are selected will be stored to the file.
