● Visualization parameters (read-only)
Display parameters are used to display internal variables, e.g. the actual motor current.

Parameter types
All these drive parameters can be read and changed via PROFIBUS using the mechanisms
defined in the PROFIdrive profile.
Parameter categories
The parameters for the individual drive objects (DO) are categorized according to 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 for each drive object and are addressed via the
parameter index for reading and writing. The following data set types can be distinguished:
– CDS: Command data set
By parameterizing several command data sets and switching between them, the drive
can be operated with different preconfigured signal sources.
– DDS: Drive data set
The drive data set contains the parameters required for switching the drive control
parameters.
The CDS and DDS data sets can be switched during operation. Further data set types
also exist, however these can only be activated indirectly by means of a DDS
changeover.
– EDS: Encoder data set
– MDS: Motor data set

Setpoint channel and closed-loop control
8.3.1
Setpoint addition
Fine tuning (correction variable) often needs to be carried out on site for applications in which
the command variables are generated by central control systems.
