EDS: Encoder Data Set

EDS: Encoder Data Set
An encoder data set contains various adjustable parameters describing the connected
encoder for the purpose of configuring the drive.
● Adjustable parameters, e.g.:
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. An
encoder data set is assigned to a drive data set via parameter p0187 (encoder 1: motor
encoder) or p0188 (encoder 2: external encoder). Only one of the two encoders can be used
at a time.
An encoder data set can only be changed over using a DDS changeover.
An encoder data set changeover without pulse inhibit (motor running under current) may only
be performed on adjusted encoders (pole position ID performed or commutation angle
determined for absolute encoders).
The DDS must be changed over in order to switch over the EDS. The MDS will also be
switched over with it.
10.2.4

MDS: Motor Data Set

MDS: Motor Data Set
A motor data set contains various adjustable parameters describing a connected motor for
the purpose of configuring the drive. It also contains certain display parameters with
calculated data.
● Adjustable parameters, e.g.:
● Display parameters, e.g.:
The parameters that are grouped in the motor data set are identified in the SINAMICS S110
List Manual by "Data Set MDS" and are assigned an index [0...n].
The motor data set is assigned to a drive data set via parameter p0186.
