Parameter assignment
Examples
Fig. 6.2.6 Gain (An.3) = 2,00 and X-Offset (An.4) = +50 %,
By means of some examples we want to demonstrate the possibilities of these
functions.
With an voltage (0...10 V) on input REF1 ± the full speed range (-100%...+100%) can
be driven (rotation = ±Analog), that means:
0% IN correspond to -100% OUT
+50% IN correspond to 0% OUT
+100% IN correspond to +100% OUT
Gain adjusted to 2
(double amplification)
X-Offset adjusted to 50 %
