Mds: Motor Data Set - Siemens SINAMICS S120 Function Manual

If encoder 1 (p0187) is changed over via DDS, then an MDS must also be changed over.
One drive object can manage up to 16 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 also selected.
NOTICE
EDS in safety mode
The encoders used for the safety function must not be changed when the data set is
switched. When the data set is switched, the safety function checks the safety-relevant
encoder data to see if it has changed. If it has changed, fault F=1670 is output with fault
value 10, which results in a non-acknowledgeable STOP A.
The safety-relevant encoder in the different data sets must, therefore, be identical.

MDS: Motor Data Set

MDS: Motor Data Set
A motor data set contains various adjustable parameters describing the 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 together in the motor data set are identified in the
SINAMICS S120/S150 List Manual by "Data Set MDS" and are assigned an index [0...n].
A separate motor data set is required for each motor that is controlled by the Control Unit via
a Motor Module. The motor data set is assigned to a drive data set via parameter p0186.
A motor data set can only be changed using a DDS changeover. The motor data set
changeover is, for example, used for:
● Switching over different motors
● Switching over different windings in a motor (e.g. star-delta changeover)
● Adapting the motor data
