3-5-2. Azimuth Adjustment
The direction shown in the figure below is referred to as the azimuth direction. A stable output signal within
the range of the specified values can be obtained by adjusting the detector head direction.
<Specified values>
A/B signal output type ...... Output format F : Amplitude 0.7 Vp-p to 1.3 Vp-p
Output format G : Amplitude 0.8 Vp-p to 1.2 Vp-p
Analog output type ........... Output format H : Amplitude 0.6 Vp-p to 1.1 Vp-p

1
Loosen the detector head mounting screws, and then bring the stopper directly against the scale bottom
surface.
2
Rotate the detector head about the stopper in the azimuth direction as shown in Fig. 3-15 to find the
location where the Lissajous’ figure has the
maximum amplitude.
3
Alternately tighten the two detector head mounting screws little by little at the detector head position
with the maximum amplitude of the Lissajous’ figure. (Fastening torque: 1.4 N
· m)
4
Check that there is no interference between the scale and detector head.
Fig. 3-16
Do not move the machine device with the stopper attached to detector head because this may result in
breakage of the detector head or the scale.
