Function Adaptation of field-frequency related parameters
- C010, C011, C017, C019, C037, C038, C039, C046, C049, C050 and
- for controllers of the “HVAC” series C051, C181, C625, C626, C627 additionally
to an application datum to be controlled, e.g. pressure, temperature, flow rate, humidity or speed.
The normalisation
- implements an absolute or relative selection or display of an application datum,
- is always carried out simultaneously for all codes indicated.
Adjustment The display value is calculated from:
CXXX
C011
200 ô
C500
C501
Example The speed setpoint is to be input and displayed as relative or absolute value.
Values: P

a) Relative normalisation in %
100.00 (%)

e.g. C500 = 4000, C501 = 10
b) Absolute normalisation in physical units
5.00 (bar)

e.g. C500 = 200; C501 = 10
Important - All codes indicated above are normalised at the same time.
- After a normalisation, the output frequency [Hz] (C050) can only be recalculated with the display
factors C500 and C501.
