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).

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 (refer to Table 5-2).
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 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.
An encoder data set can only be changed over using a DDS changeover.
Each encoder may only be assigned to one drive and within a drive must – in
each drive data set – either always be encoder 1, always encoder 2 or always
encoder 3.
