Synoptic of the "Rampeauto" servo

The attached image file shows a synoptic of the "Rampeauto" servo.

The gain of the input gain G1 has changed and is set to G1 = 5.1

So the output EPS1 (AC2) shows the input signal with a gain G4 = G1 * G2 = 5.1 * 5.2 = 26.5

If you measure the offset at EPS1 output, it should be divided by 26.5 to obtain it at the input (Detect Sig).


Remark:
The attenuator "Gain Piezo" has an effect on the dynamic of "Piezo Sig" output.
For instance, if "Gain Piezo" is set to position 0.7 as currently (on 10 max), the dynamic will be:

D = +/- 0.7/10 * 14 * 10 = +/- 10V

(Gain Ampli HT = 10)
