Parameter categories
The parameters for the individual drive objects (DO) are categorized according to data sets as
follows:
● Data-set-independent parameters
● Data-set-dependent parameters

8.5.1.1

Setpoint channel

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.
You achieve the correction variable using the addition point for the main and additional setpoint
in the setpoint channel. Both variables are imported simultaneously via two separate or one
setpoint source and added in the setpoint channel.

These parameters exist only once per drive object.
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
