7.3.2 Technology controller
7.3.2.1 Features
Simple control functions can be implemented with the technology controller, e.g.:
● Level control
● Dancer position/tension control
● Pressure control
● Flow control
● Simple closed-loop control without higher-level controller
The technology controller features:
● Separate fixed values
● Integrated motorized potentiometer
● Technology controller with:
– Two scalable setpoints
– Ramp-function generator in setpoint channel
– Filter for actual value and setpoint channel
– Two modes for derivative component injection
– Pre-control
– Output ramp with limits
– Scalable output signal
7.3.2.2 Description
Motorized potentiometer
This function is used to simulate an electromechanical potentiometer for setpoint input.
Separate binector inputs for higher (p2235) and lower (p2236) are used to adjust the input
setpoint: The potentiometer limits are defined within maximum (p2237) and minimum
(p2238) values. The setpoint input is routed to an internal ramp-function generator, for which
both a ramp-up (p2247) and a ramp-down (p2248) time, as well as an initial value (p2240)
can be defined. Initial rounding can be activated to fine-tune the setpoint, whereby the
acceleration of the setpoint is calculated as follows:
a = 0.0001·
MAX [p2237; |p2238|] · 0.13

The connector output of the motorized potentiometer (r2250) can, for example, be used as a
setpoint for the technology controller. The motorized potentiometer requires the OFF1
enable for operation.
