9. Securing the shaft scale
Determine the shaft scale position. To obtain stable signals, rotate and position the shaft
scale so that the head and shaft scale have the positional relationship shown in the
figure.
As shown in the figure, magnetic recording in the shaft scale is possible only for a
range of approximately 70 degrees (9 mm/0.35") in the circumferential direction. Note
that signals cannot be detected for positions that are not recorded magnetically.
Tighten the hexagonal bolts 3 on both ends.
Tightening torque: 5.4 N
10. Removing the holder bracket
Pull the holder brackets to the right and left to remove.
11. Connecting the cable and counter unit
