A command data set contains the following (examples):
● Binector inputs for control commands (digital signals)
– ON/OFF, enable signals (p0844, etc.)
– Jog (p1055, etc.)
● Connector inputs for setpoints (analog signals)
– Speed setpoint (p50433)
– Torque setpoints (p50500, p50501)
A drive object can manage 2 command data sets.
The following parameters are available for selecting command data sets and for displaying
the currently selected command data set:
● Binector input p0810 BI: Command data set (CDS) selection
● r0836: Displays selected data set
Example: Switching between command data set 0 and 1

DDS: Drive data set
A drive data set contains various adjustable parameters that are relevant for open-loop and
closed-loop drive control:
● Numbers of the assigned encoder data sets:
– p0187 and p0188: Up to 2 assigned encoder data sets (EDS)
● Various control parameters, e.g.:
– Speed limits min./max. (p50512, p50513)
– Characteristic data of ramp-function generator (p50295 ff)
– Characteristic data of controller (p50540 ff)
– ...
The parameters that are grouped together in the drive data set are identified in the
SINAMICS DCM List Manual by "DDS" and are provided with index [0...n].
