Application class 1:
In the simplest case the drive is controlled via a main setpoint (e. g.
speed setpoint) via PROFIBUS (Figure 1). The complete speed control
takes place in the drive controller. The automation device includes all the
technological functions for the automation process. PROFIBUS acts only
as transmission medium between the automation system and drive
controller. The normal cyclical data communication of the PROFIBUS-DP
is used (Data Exchange). This application is primarily used in the area of
classic drive technology (e.g. materials handling technology). A PLC is
used mainly as the automation system. Clock synchronism and cross
traffic on the bus system are not necessary for this application class.
