Figure 4. Base plate after screw tightening and centering tool removed
Step 2. Remove the centering tool
Step 3. Encoder body unit assembly
With the base plate centered to the shaft as seen in Figure
4, mount the encoder body unit to the motor’s shaft. See
gure 5.
Figure 5. Mounting encoder body unit to the base plate
Step 4. Lock codewheel onto the motor shaft
Insert the hex wrench into the set-screw opening of the
encoder body unit and apply a downward force (as indi-
cated by arrow), then tighten the set screw. See Figure 6.
The recommended torque is 15-18 oz-in (0.9-1.2 in-lbs).

Figure 6. Tightening encoder body unit set-screw to the motor’s shaft
Perform the same action on the opposite side of the en-
coder. Note that you will need to pull the“L-shape”mecha-
nism down and to the right instead.
The closure is considered complete when the “hinge” is
clearly visible through the set-screw openings on both
sides of the encoder body unit. See gure 7 (AFTER)
The completed encoder assembly is now ready for opera-
tion. See gure 8.

BEFORE AFTER
Press t the encoder body unit to the base plate, ensuring
that all four snap points are well locked.
The set screw tightening process will:
1. Lock the code wheel's hub to the motor shaft
2. Physically align the code wheel's index position to that
of the detector IC (index channel may not necessarily
be triggered electrically).
Step 5. Release codewheel and close set-screw outlet
Using the hex wrench, pull the“L-shape”protrusion down
and to the left. See gure 7 (BEFORE). This action releas-
es the internal codewheel holding mechanism and also
serves to close the set-screw opening.
* 1.5mm Hex wrench should be used to fasten M3 set screw in Figure 6
