1. Move the carriage to a reference point (e.g. machine zero, real zero). Mark the carriage
position on the HPLA profile (felt pen).
2. Switch off the actuator at the main switch and disconnect it from the electrical supply.
3. Remove the motor and resolver cable
4. Loosen the motor fastening
5. Pull the motor away from the gearbox
6. Measure distance R, dimension from the claw coupling to the motor flange (accuracy
+/- 0.1 mm).
7. Loosen the clamp screw of the claw coupling half and pull this off the motor shaft.
8. Remove all traces of lubricant from the motor shaft and the hole of the claw coupling.
9. Place the claw coupling half on the new motor at the distance R. If necessary, rub down the
motor shaft using emery paper, grade 360.
Note
There should be 1mm play in the axial direction between the coupling halves after
mounting. Axial pressure must be avoided at all costs!
10. Tighten the clamp screws of the claw coupling.
11. Install the motor (if necessary, turn the motor in order to find the tooth spaces) and tighten
the motor fastening (97).
12. Connect motor and resolver cables - check the direction of rotation is correct
13. Switch on the actuator.
