10.1 Parameter
Parameter types
The following adjustable and display parameters are available:
● Adjustable parameters (write/read)
These parameters have a direct impact on the behavior of a function.
Example: Ramp-up and ramp-down time of a ramp-function generator
● Display parameters (read only)
These parameters are used to display internal variables.
Example: Current motor current

All these drive parameters can be read and changed via PROFIBUS using the mechanisms
defined in the PROFIdrive profile.
Parameter categories
The parameters of the individual drive objects are categorized into data sets as follows:
● Data-set-independent parameters
These parameters exist only once per drive object.
● Data-set-dependent parameters
These parameters can exist a multiple number of 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 drive
control configurations.
