Commissioning with STARTER
The "technology controller" function module can be activated via the commissioning wizard
or the drive configuration (configure DDS).
You can check the actual configuration in parameter r0108.16.
Application example: Fill level control
The objective here is to maintain a constant level in the container.
This is carried out by means of a variable-speed pump in conjunction with a sensor for
measuring the level.
The level is determined via an analog input (e.g. AI0 on TB30) and sent to the technology
controller. The level setpoint is defined in a fixed setpoint. The resulting controlled variable is
used as the setpoint for the speed controller.
In this example, a Terminal Board 30 (TB30) is used.
