Connecting a PG/PC with the STARTER/Startdrive commissioning tool
The following connection options are available for commissioning a Control Unit with a PG/PC
using the commissioning tool.
● STARTER: PROFIBUS, PROFINET, or Ethernet.
● Startdrive: PROFINET or Ethernet.
A.1.1.1 PROFIdrive application classes
According to the scope and type of application processes, PROFIdrive is divided into a total
of 6 application classes, of which the 3 important classes are compared below:
● Class 1 (AK1):
The drive is controlled via a speed setpoint by means of PROFIBUS/PROFINET. Speed
control is fully handled in the drive.
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 closed-loop position control.
● Class 4 (AK4):
This application class defines a speed setpoint interface, where the speed control is realized
in the drive and the closed-loop position control in the control system, such as is required
for robotics and machine tool applications with coordinated motion sequences on multiple
drives.
Motion control is primarily implemented using a central numerical controller (NC).
