Technology controller
Features
Simple control functions can be implemented with the technology controller, e.g.:
● Level control
● Temperature control
● Dancer 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
● 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.
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.
Pre-control 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 fed in, for example, via an analog input.
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.
