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 p0823 are used to select a drive data set. They represent
the number of the drive data set (0 to 31) in binary format (where p0823 is the
most significant bit).

Supplementary conditions and recommendations
S Recommendation for the number of drive data sets for a drive
The number of drive data sets for a drive should correspond to the options for
switchover. The following must therefore apply:
p0180 (DDS) w max (p0120 (PDS), p0130 (MDS))
S Maximum number of DDS for one drive object = 32 DDS
EDS: Encoder Data Set
An encoder data set contains various adjustable parameters describing the con-
nected encoder for the purpose of configuring the drive.
S Adjustable parameters, e.g.:
– Encoder interface component number (p0141)
– Encoder component number (p0142)
– Encoder type selection (p0400)
The parameters that are grouped together in the encoder data set are identified in
the SINAMICS parameter list by "Data Set EDS" and are assigned an index [0..n].
A separate encoder data set is required for each encoder controlled by the Control
Unit. Up to 3 encoder data sets are assigned to a drive data set via parameters
p0187, p0188, and p0189.
One drive object can manage up to 3 encoder data sets. The number of encoder
data sets configured is specified in p0140.
When a drive data set is selected, the assigned encoder data sets are selected
automatically.
Note
Only the same encoder data sets can be assigned to all the drive data sets for one
drive object. You cannot switch between different encoder data sets.
