Begin by selecting the appropriately sized shaft adapter and insert it into the centering tool. No adapter is needed for a 6 mm motor shaft. STEP 2 STEP 3 1. Remove the centering tool. 2. Take the shaft adapter out of the centering tool. 1. Rotate the pre-installed alignment tool clockwise and completely to the right so that the pre-installed shaft set screw is visible. 2. Insert the shaft adapter into the encoder making sure the adapter is properly aligned with the keyway in the metal hub. No adapter is needed for a 6 mm motor shaft. 2. Place the plastic base over the motor shaft. 3. Slide the centering tool and shaft adapter over the motor shaft. The centering tool will hold the base in the proper position. 3. Insert the placement tool into the assembly. This placement tool holds the encoder’s hub and shaft adapter in the proper position for installation onto the motor shaft. 4. While holding the centering tool down in place, install screws to secure the base to the motor body. 4. Position the encoder so it can snap onto the plastic base. The encoder will only snap into place in one orientation. 5. Slide the encoder onto the motor shaft applying force only to the placement tool to maintain proper alignment of the encoder’s hub and shaft adapter. 6. Ensure all 4 locking tabs are secured in place over the encoder hub. STEP 4 1. Insert the Allen Wrench into the notch on the top. 2. listed on the applicable AMT encoder datasheet. STEP 5 1. Rotate the placement tool and alignment tool counterclockwise until the tabs align with the openings. 2. Remove both tools from the encoder. 3. rotating freely. cuidevices.com Additional Resources: Product Page CUI DEVICES | SERIES: AMT12 | DESCRIPTION: MODULAR INCREMENTAL ENCODER date 08/05/2022 | page 7 of 7 REVISION HISTORY rev. description date 1.0 initial release 09/03/2020 1.01 added motor shaft tolerance details, updated start-up details 09/10/2021 logo, datasheet style update 08/05/2022 1.02 The revision history provided is for informational purposes only and is believed to be accurate.
