6.7.2 Application classes
Description
There are different application classes for PROFIdrive according to the scope and type of the
application processes. PROFIdrive features a total of 6 application classes, the 3 most
important are considered here:
● Class 1 (AK1):
The drive is controlled using a speed setpoint via PROFIBUS/PROFINET. The complete
closed-loop speed control is realized in the drive itself.
Typical application examples include simple frequency converters for controlling pumps
and fans.
● Class 3 (AK3):
In addition to the speed control, the drive also includes a positioning control, which
means that it operates as an autonomous single-axis positioning drive while the higher-
level technological processes are performed in the control system. Positioning requests
are transferred to the drive controller via PROFINET (or PROFIBUS) and started.
● Class 4 (AK4):
This PROFIdrive application class defines a speed setpoint interface where the closed-
loop speed control is executed in the drive and the closed-loop position control in the
control system. This is required for robotic and machine tool applications with coordinated
motion sequences distributed across several drives.
Motion control is primarily implemented using a central numerical controller (NC). The
position control loop is closed via the bus, i.e. the communication between the controller
and the drive must be isochronous.
