404XE Series Product Manual31 Parker Hannifin CorporationEMN Automation - ParkerIrwin, PennsylvaniaRotary Encoder Installation - 404XEFollow the below procedure to install the rotary encoder (E5 option) on the 404XE:Tools Required: 1.5mm, 2.0mm and 0.050” Hex Wrenches, Dial Indicator, Loctite 638 or EquivalentStep 5: Verify concentricity of the mandrel. Using a dial indicator, measure the runout (wobble) at the end ofthe mandrel by manually traversing the table. Runout should not exceed 0.001”.Step 6: Remove cover from rotary encoder assembly. Check to make sure slide lock is all the way out. Theslide lock in the outward position provides a seat for the encoder hub during installation to ensure hub is cen-tered properly.Step 1: Remove power from unit and allow all components to reach room temperature.Step 2: Clean the counterbore in the idler end of drive screw shaft that extends through the end block using aclean cloth and acetone or alcohol. Remove all oil or foreign material that might be present.Step 3: Apply a light film of Loctite 638 to the counterbore.Step 4: Install the wedge into the end of the mandrel and insert mandrel/wedge assembly into the drive screwshaft counterbore until the mandrel bottoms out at the shoulder. Install the long socket head cap screw andtighten.Step 11: Orient the encoder so that the mounting holes align with the tapped holes in end block. Note standardorientation from the factory is such that the cable egress is at the bottom. Install and tighten two (2) button headscrews.Step 8: Rotate encoder hub to align the set screw with one of the flats on the mandrel.Step 10: Tighten set screw an additional 1/4 turn to apply approximately 20oz-in of torque. Note overtighteningwill deform the mandrel and cause encoder removal to be difficult.Step 9: Maintain pressure on the hub to ensure that it is seated in the centering mechanism and secure hub tomandrel by tightening set screw until in contacts the shaft.Step 7: Align encoder hub with mandrel and gently push hub onto mandrel until the encoder contacts the endblock. DO NOT apply force to any part of the encoder except for the hub.Step 12: Push slide lock in completely. Visually verify that a gap is present between the disk and mask on theunderside of the printed circuit board. If no gap is present, remove encoder and reinstall. Manually traverse thetable over the entire travel and check that the mandrel and encoder printed circuit board rotate freely without anynoises or increased torque.Step 13: Install cover by snapping it into place.
