DDS: Drive data set
A drive data set contains various adjustable parameters that are relevant with respect to
open and closed-loop drive control:
● Numbers of the assigned motor and encoder data sets:
● Various control parameters, e.g.:
The parameters that are grouped together in the drive data set are identified in the
SINAMICS parameter list by "Data Set DDS" and are assigned an index [0..n].
It is possible to parameterize several drive data sets. You can switch easily between different
drive configurations (control type, motor, encoder) by selecting the corresponding drive data
set.
One drive object can manage up to 32 drive data sets. The number of drive data sets is
configured with p0180.
Binector inputs p0820 to p0824 are used to select a drive data set. They represent the
number of the drive data set (0 to 31) in binary format (where p0824 is the most significant
bit).
● p0820 BI: Drive data set selection DDS bit 0
● p0821 BI: Drive data set selection DDS bit 1
● p0822 BI: Drive data set selection DDS bit 2
● p0823 BI: Drive data set selection DDS bit 3
● p0824 BI: Drive data set selection DDS, bit 4

Example: Switching between command data set 0 and 1
– p0186: assigned motor data set (MDS)
– p0187 to p0189: up to 3 assigned encoder data sets (EDS)
– Fixed speed setpoints (p1001 to p1015)
– Speed limits min./max. (p1080, p1082)
