Technology controller

Description
The "technology controller" function module allows simple control functions to be
implemented, e.g.:
● Liquid level control
● Temperature control
● Dancer position control
● Pressure control
● Flow control
● Simple control without higher-level control
● Tension control
The technology controller features:
● Two scalable setpoints
● Scalable output signal
● Separate fixed values
● Separate motorized potentiometer
● The output limits can be activated and deactivated via the ramp-function generator.
● The D component can be switched to the system deviation or actual value channel.
● The motorized potentiometer of the technology controller is only active when the drive
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 field bus (e.g. PROFIBUS).
Pre-control can be integrated via a connector input.
