4.1 Example 1: Dosing system
The "Dosing system" application example describes different filling stations of a packaging machine.
The containers of these machine parts are to be filled using the least amount of space or the shortest
possible time. It is also important that the exact amount is supplied via the feed screw. Two 9300
servo position controllers with power−optimised servo motors are used as drive components.
The 9300 servo position controller contains functions which could previously only be offered by a
higher−level control (e.g. PLC). Positioning tasks which are similar to this example can easily be
achieved at minimum expense using this controller.
