DDS: drive data set
A drive data set contains various adjustable parameters that are relevant with re-
spect to open and closed-loop drive control:
S Numbers of the assigned motor and encoder data sets:
-- p0186: assigned motor data set (MDS)
-- p0187 to p0189: up to 3 assigned encoder data sets (EDS)
S Various control parameters, e.g.:
-- Fixed speed setpoints (p1001 to p1015)
-- Speed limits min./max. (p1080, p1082)
-- Characteristic data of ramp-function generator (p1120 ff)
-- Characteristic data of controller (p1240 ff)
-- ...
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].
More than one drive data set can be parameterized. You can switch easily between
different drive configurations (control type, motor, encoder) by selecting the
corresponding drive data set.
