8.2.9.1 Incorporation of drives in automation systems / plant characterization
Application classes
NOTE
8.2-90
This section presents the different variants for incorporation of drives in
automation systems.
Nowadays, drive applications are implemented in many different ways.
The following table defines the various application classes in which
drives are used. The application classes are typical examples from the
total spectrum of electrical drive engineering and are not necessarily
covered by a specific equipment characteristic.
Application class
1 Standard drive
2 Standard drive with distributed
technology controller (continuous
process)
3 Basic positioning drive with
distributed position control and
interpolation
4 Positioning with central
interpolation and position control
Optional:
DSC (Dynamic Servo Control)
5 Positioning with central
interpolation and distributed
position control
6 Motion control in clocked
processes or distributed angular
synchronism
1) The cyclical interface can also be operated clock synchronously if, for
example, simultaneity of action in several drives is required.
2) For all application classes: Acyclical interface for parameters, diagnosis,
identification
3)
This application class is not described in this document
Table 8.2-15 Application classes
When the MASTERDRIVES unit is used as PROFIdrive V3 slave, only
application classes 1 and 4 are used!
Several MASTERDRIVES can be connected to one PROFIdrive V3
master in class 1 as slave (Monomaster operation).
