Operation
9.1 Basic information
Parameter categories
The parameters of the individual drive objects are categorized into data sets as follows:
● Data set-independent parameters
● Data-set dependent parameters
The CDS and DDS can be switched over during normal operation. Additional types of data
set also exist, but these can only be activated indirectly by means of a DDS changeover.
● EDS - Encoder Data Set

These parameters exist only once per drive object.
These parameters can exist several times for each drive object 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 automatic
speed control configurations.
