DDS: Drive data set
A drive data set contains various adjustable parameters that are relevant with respect to
open-loop and closed-loop drive control:
● Various control parameters, e.g.:
– Fixed speed setpoints (p1001 to p1015)
– Speed limits min./max. (p1080, p1082)
– Characteristic data of ramp-function generator (p1120 ff)
– Characteristic data of controller (p1240 ff)
– ...
The parameters that are grouped together in the drive data set are identified in the
parameter list by "Data set DDS" and are assigned an index [0..n].
It is possible to parameterize several drive data sets. You can switch easily between different
drive configurations by selecting the corresponding drive data set.
Binector inputs p0820 and p0821 are used to select a drive data set. They represent the
number of the drive data set (0 to 3) in binary format (where p0821 is the most significant
bit).
● p0820 BI: Drive data set selection DDS, bit 0
● p0821 BI: Drive data set selection DDS, bit 1
Copying the command data set (CDS)
Set parameter p0809 as follows:
1. p0809[0] = Number of the command data set to be copied (source)
2. p0809[1] = Number of the command data to which the data is to be copied (target)
3. p0809[2] = 1
Start copying.
Copying is finished when p0809[2] = 0.
Copying the drive data set (DDS)
Set parameter p0819 as follows:
1. p0819[0] = Number of the drive data set to be copied (source)
2. p0819[1] = Number of the drive data set to which the data is to be copied (target)
3. p0819[2] = 1
Start copying.
Copying is finished when p0819[2] = 0.
