7.2 Analog in- and outputs
7.2.1 Brief description analog inputs
By selecting an input interface (An.00/ 10) input AN1 or AN2 can be adjusted to the applied input signal. By
An.20 the third analog input can be switched additionally to AN1. Subsequently the analog inputs are smoothed
in an electronic filter (
An.01/ 11/ 21) by averaging. A save mode can be adjusted with An.02/12/22 and activated
with a programmable input (
An.03/13/23). To avoid voltage fluctuations and ripple voltages around the zero
point the analog signal can be faded out around the zero point up to ±10 % (An.04/14/24). In the characteristic
amplifier the input signals can be influenced in X and Y direction as well as in the rise (
An.05...07/ 15...17/
25...27). At the
output of the characteristic amplifier the signal can be limited to minimum and maximum value
(An.08, 09/18, 19/28, 29). At the
output of the block it can be defined with
An.30 which analog signal serves
as reference value and which one serves as auxiliary value. The ru-Parameters are used for the display of the
analog signal pre and post amplifier. The internal values are limited to ±400%.
