Basic information about the drive system

12.1

Parameter

Parameter types
The following adjustable and display parameters are available:
● Adjustable parameters (write/read)
● Display parameters (read only)
Figure 12-1
All these drive parameters can be read and changed via PROFIBUS using the mechanisms
defined in the PROFIdrive profile.
Parameter categories
The parameters of the individual drive objects are categorized into data sets as follows:
● Data-set-independent parameters
● Data-set-dependent parameters
Drive Functions
Function Manual, (FH1), 07/2007 Edition, 6SL3097-2AB00-0BP4
These parameters have a direct impact on the behavior of a function.
Example: Ramp-up and ramp-down time of a ramp function generator
These parameters are used to display internal variables.
Example: Current motor current
Parameter types
These parameters exist only once per drive object.
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.
