(An.5...7; An.15...17;
An.25...27)
With these parameters the input signals can be adapted in X and Y direction as well
as in the rise to the requirements. In the case of factory setting no zero point offset is
adjusted, the rise (gain) is 1, i.e. the input value corresponds to the output value of
this step (see Fig. 6.2.7.a) The output value is calculated according to following formula:
Out = Amplification ï ( In - Offset X) + Offset Y
Input value (In)
Output value (Out)
Fig. 6.2.7.a
Factory setting: no Offset, Gain 1
By means of some examples, we want to show the possibilities of this function.
According to Fig. 6.2.7.b
1. adjustment of the X-Offset for input AN1 to 50 (%)
2. adjustment of the amplificaiton to 2
Fig. 6.2.7.b
X-Offset (An.6)=50%; amplification (An.5)=2.00
With these settings the entire speed
range can be driven with 0...10 V
via input AN1.
