to an application datum to be controlled, e.g. pressure, temperature, flow rate, humidity or speed.
- The normalisation implements an absolute or relative selection of an application datum.
- All codes indicated are normalised at the same time.
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 (%)
50
200 ô
4000
10
e.g. C500 = 4000, C501 = 10
b) Absolute normalisation in physical units
5.00 (bar)
50
200 ô
200

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.
