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
– DDS: Drive data set
– 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.
This can be carried out 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.
8.3.2
Direction of rotation changeover
You have the following options of subsequently inverting the phase sequence:
• Replace the motor cable.
• Enter a negative setpoint or change the device parameterization.

Operating Instructions, 02/2022, A5E31872818
By parameterizing several command data sets and switching between them, the drive can
be operated with different preconfigured signal sources.
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.
