5.2.4 Zero adjustment and amplification

After the ad

ustment has been carried out, the volta

e of the output si

nal at 0% and

100% of the reference signals can be set with the parameters

Offset 585 (zero ad-

justment) and

Amplification 586.

The zero adjustment with the parameter

Offset 585 is done specific to the application

as a percentage of the final value of the analog output (10 V).

Via the parameter

Amplification 586 the amplification can be set as a percenta

e o

the final value of the analog output (10 V).

In the factory settin

, the zero point has been set at 0% Offset, i.e. minimum value o

the reference signal equal to 0 V output signal. The factory setting amplification equal

to 100% means that the output signal is 10 V when the reference value is reached.

5.2.4.1 Examples

he actual value parameter is mapped to the analo

output si

nal as a function of the

selected parameters

Offset 585 and Amplification 586. The followin

examples show

the application-specific adaptation for an analog voltage signal.

The setting of the parameter

Offset 585 to

0.00% and the parameter

Amplification

586 to 1000.0% means that the output

signal:

− is 0 V at 0% of the reference signal,

− is 10 V at 10% of the reference signal.

to -5,00% and the parameter

Amplifica-

tion

586 to 100,0% means that the out-

put signal:

− is -0.5 V at 0% of the reference sig-

nal,

− is 9.5 V at 100% of the reference

signal.
