Technology controller

Simple control functions can be implemented with the technology controller. These include:

● Level control

● Temperature control

● Dancer roll position control

● Pressure control

● Flow control

● Simple closed-loop controls without higher-level controller

● Tension control

Function description

The technology controller is designed as a PID controller, whereby the differentiator can be

switched to the control deviation channel or the actual value channel (factory setting). The P,

I, and D components can be set separately. A value of 0 deactivates the corresponding

component. Setpoints can be specified via two connector inputs. The setpoints can be scaled

via parameters (p2255 and p2256). A ramp-function generator in the setpoint channel can be

used to set the setpoint ramp-up/ramp-down time via parameters p2257 and p2258. The

setpoint and actual value channel each have a smoothing element. The smoothing time can be

set via parameters p2261 and p2265.

The setpoints can be specified via separate fixed setpoints (p2201 to p2215), the motorized

potentiometer, or via the fieldbus (e.g. PROFIBUS).

Precontrol can be integrated via a connector input.

The output can be scaled via parameter p2295 and the control direction reversed. It can be

limited via parameters p2291 and p2292 and interconnected as required via a connector output

The actual value can be integrated, for example, via an analog input on the TB30.

If a PID controller has to be used for control reasons, the D component is switched to the

setpoint/actual value difference (p2263 = 1) unlike in the factory setting. This is always

necessary when the D component is to be effective, even if the reference variable changes. The

D component can only be activated when p2274 > 0.

The technology controller is characterized by the following features:

● Two scalable setpoints

● Scalable output signal

● Separate fixed values

● Integrated motorized potentiometer

● The output limits can be activated and deactivated via the ramp-function generator.
