6.3 Head # 1/2 - Signal Adjustment
In this function, the signals read from the encoder are compared with the ideal values set by AMO. Thus, you
can determine the optimal mounting and reposition the encoder if necessary.
Amplitude Sin/Amplitude Cos
Here you can determine the deviation from ideal air gap.
 „+“ Air gap too large (Encoder mounted too far away from the scale tape)
 „-“ Air gap too small (Encoder mounted too close to the scale tape)
Phase Sin/Cos und Offset Sin/Cos
These measuring values should be always in the green range. Only in the case of a faulty amplitude, these
values will show large deviation from the center point.
