Operation
6.3 Basic information about the drive system
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).
● p0820 BI: Drive data set selection DDS, bit 0
● p0821 BI: Drive data set selection DDS, bit 1
● p0822 BI: Drive data set selection DDS, bit 2
● p0823 BI: Drive data set selection DDS, bit 3
● p0824 BI: Drive data set selection DDS, bit 4
Supplementary conditions and recommendations
● Recommendation for the number of DDS in a drive
The number of DDS in a drive should correspond with the number of changeover options;
in other words
p0180 (DDS) ≥ p0130 (MDS).
● Max. number of DDS for one drive object = 32 DDS
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.:
– 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.
An encoder data set can only be changed 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.
One application for the EDS changeover would be a power component with which several
motors are operated in turn. A contactor circuit is used to changeover between these motors.
Each of the motors can be equipped with an encoder or be operated without an encoder.
Each encoder must be connected to its own SMx.
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 selected
automatically.
