Normalisation - Adaptation of a field related parameter toan application datumtobe controlled (e.g. pressure,
temperature, flow rate, humidity, speed) under C500 and C501.
- The following codes are normalised at the same time:
- C010, C011 C017, C019, C037, C038, C039, C046, C049, C050, C051, C181, C625, C626,
C627
- After a normalisation, the output frequency [Hz](C050)can only be recalculated with the display
factors C500 and C501 (see formulas in chapter 7.6.3).
- In factory setting, all field related parameters refer to the frequency. Input and display in Hz. The
values of C037, C038, C039, C046, C051, C181 refer to C011.
Factory setting
A percentage of the input or display values
corresponds to the frequency in Hz.
0 % 100 % Setpoint or act. value

Adjustment The value set under C071 correspond to the following integral action times T

.

Guide values for pressure
control and flow rate
The values in the following table are for guidance for pressure and flow-rate controls. A fine
adjustment is therefore always necessary.
C070, C071 and C072 must be set so that the target value is
- reached quickly and
- with minimum overshooting
when the setpoints and actual values are changed.
The differential component K
D
(C072)is usually not required for pressure and flow-rate controls
(set C072 = 0).
