Basic information about the drive system
The following adjustable and display parameters are available:
● Adjustable parameters (write/read)
These parameters have a direct impact on the behavior of a function.
Example: Ramp-up and ramp-down time of a ramp-function generator
● Display parameters (read-only)
These parameters are used to display internal variables.
Example: Current motor current
Figure 13-1 Parameter types
All these drive parameters can be read via PROFIBUS and changed by means of p
parameters using the mechanisms defined in the PROFIdrive profile.
The parameters of the individual drive objects are categorized into data sets as follows:
● 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
By parameterizing several command data sets and switching between them, the drive
can be operated with different pre-configured signal sources.
– DDS: Drive Data Set
The drive data set contains the parameters for switching between different drive
control configurations.
