DIGITAL INDUSTRIAL CONTROLLER
english
Accordingly, several adaption cycles are run until the required setpoint is reached,
thus increasing the quality of the controller parameters. A new setpoint is set in up to
5 stages. However, only as many steps are run through as are needed to find the
optimum controller parameters.
Depending on the scaling range of the controller input (PVl ... PVh / P2l ... P2h), the
setpoint change must exceed a specific amount for adaption to take place. In the
following table you find the minimum set point changes to execute in dependence of
the configured controller inputs 1 and 2. The data applies to activation of a setpoint
in one stage.
Configured controller input minimum setpoint change to execute
Standard signal 0 … 10 V (PVh - PVl) • 0,0135
Standard signal 0 … 20 mA (PVh - PVl) • 0,0135
Standard signal 4 … 20 mA (PVh - PVl) • 0,0169
Frequency-analog signal (PVh - PVlu) • 0,0153
Pt 100 (-200 … + 850 °C) 20,0 K
Thermocouple type J (-200 … 1200 °C) 16,5 K
Thermocouple type K (-200 … 1370 °C) 28,0 K
Thermocouple type T (0 … 400 °C) 16,5 K
Thermocouple type R (0 … 1760 °C) 50,0 K
Thermocouple type S (0 … 1760 °C) 50.0 K
note: P*h: PVh oder P2h; P*l: PVl oder P2l.
If the setpoint change is too less this status is displayed by the code 07 (see Par.
7.6).
Handling adaption if you have an inadequate knowledge of the process
If you have an inadequate knowledge of the process (time response and gain etc.)
when commissioning a control system, you are advised to proceed as follows when
using the self-optimisation function by adaption:
