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.:
– Motor component number (p0131)
– Motor type selection (p0300)
– Rated motor data (p0304 ff)
– ...
● Display parameters, e.g.:
– Calculated rated data (p0330 ff)
– ...
The parameters that are grouped together in the motor data set are identified in the
SINAMICS parameter list 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:
● Changing over between different motors
● Changing over between different windings in a motor (e.g. star-delta changeover)
● Motor data adaptation
If several motors are operated alternately on one Motor Module, a corresponding number of
drive data sets must be created. See "Functions / Drive functions" for additional information
and instructions on changing over motors.
One drive object can manage up to 16 motor data sets. The number of motor data sets in
p0130 may not exceed the number of drive data sets in p0180.
