Function modules 7.2 Technology controller

The D component can be switched to the control deviation or actual value channel.

The motorized potentiometer of the technology controller is only active when the drive pulses are enabled.

7.2.3Commissioning 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.

7.2.4Examples

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, terminal board 30 (TB30) is used.
