Technology controller

Simple closed-loop control functions can be implemented with the technology controller, e.g.:
● Level control
● Temperature control
● Dancer roll position control
● Pressure control
● Flow control
● Simple closed-loop controls without higher-level controller
● Tension control
The technology controller 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.
● The D component can be switched into the control deviation or actual value channel.
● The motorized potentiometer of the technology controller is only active when the drive
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 (r2294).
The actual value can be integrated, for example, via an analog input on the TB30.
