Parameter categories
The parameters are divided into data sets (see "Operation / data sets") as follows:
● Data-set-independent parameters
These parameters exist only once per drive object.
● Data-set-dependent parameters
These parameters can exist several times and can be addressed via the parameter index
for reading and writing. A distinction is made between various types of data set:
–
CDS: Command data set
By parameterizing several command data sets and switching between them, the drive
can be operated with different pre-configured signal sources.
– DDS: Drive data set
The drive data set contains the parameters for switching between different drive
control configurations.
The CDS and DDS can be switched over during normal operation.
6.2.2 Data sets
Description
For many applications, it is beneficial if more than one parameter can be changed
simultaneously by means of one external signal during operation or when the system is
ready for operation.
This can be carried out using indexed parameters, whereby the parameters are grouped
together in a data set according to their functionality and indexed. Indexing allows several
different settings, which can be activated by switching the data set, to be defined in each
parameter.
Note
Copying data sets
The command and drive data sets can be copied in STARTER (Drive -> Configuration ->
"Command data sets" or "Drive data sets" tab).
The displayed command and drive data sets can be selected in the associated STARTER
screen forms.
