Basic information about the drive system

14.1

Parameter

Overview
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

All drive parameters can be read via PROFIBUS and changed by means of p parameters 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
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

Parameter types
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.
