Operation
6.3 Basic information about the drive system
Parameter categories
The parameters for the individual drive objects (see "Drive objects") are categorized
according to data sets as follows (see "Operation/data sets"):
● Data-set-independent parameters
These parameters exist only once per drive object.
● Data-set-dependent parameters
These parameters can exist several times for each drive object and can be addressed via
the parameter index for reading and writing. A distinction is made between various types
of data set:
– CDS: Command data set
– DDS: Drive data set
The CDS and DDS can be switched over during normal operation. Additional data record
types also exist, however these can only be activated indirectly by means of a DDS
changeover.
– EDS: encoder data set
– MDS: Motor data set
188
By parameterizing several command data sets and switching between them, the drive
can be operated with different pre-configured signal sources.
The drive data set contains the parameters for switching between different drive
control configurations.
