Provide an upward lifting
force, during the set-screw
tightening process.
Step 4. Tighten the codewheel-hub assembly
a) Ensure that all three latches are secure. The latches should snap firmly without
any visible bulging.
b) Apply an upward lifting force and rotate the hex wrench clockwise until the hub
set-screw is securely fastened against the motor shaft. The recommended torque
for tightening the set-screw is 15-18 oz-inch (0.1 – 0.13 N-m).
c) Remove the hex wrench by pulling it straight out from the encoder body.
CAUTION: For best performance, the baseplate and plastic housing assembly are designed for one-time
assembly only. Removal and re-assembly should be avoided as the latches may be weakened.
