1326A Encoder Feedback Mounting Adapter
Instructions
2
o 1. Remove the backplate from the end of the motor.
o 2. Thoroughly clean the shafts, coupling bores and mounting faces to
remove oil or any other substance that may be present.
o 3. Important: The supplied flexible coupling contains an insulating
sleeve on one end. The sleeve guards against motor generated heat
migrating to the encoder. The coupling end with the insulating sleeve
must be positioned towards the encoder.
Using the supplied allen wrench, attach the flexible coupling to the
stub shaft of the motor. When tightening, use no more than 1.8-2.0
N-m (16-18 lb.-in.) of torque. The shaft must be visible through the
spacings in the coupling.
Motor Shaft
Coupling
Important: The coupling is a flexible type which must be installed in
a relaxed state (not compressed or stretched). Installation in the
compressed state will limit the ability of the coupling to flex
adequately. Installation in a stretched condition may exceed the
couplings yield point when flexed. Either condition will shorten the
life of the coupling.
o 4. Attach the adapter to the motor using the supplied screws. Tighten the
screws using no more than 2.3-2.8 N-m (20-25 lb.-in.) of torque
o 5. Insert the encoder shaft into the coupling. Position the encoder on the
adapter and rotate the servo clamps into the groove on the encoder.
o 6. Tighten the servo clamps.
o 7. Remove the inspection plug on the side of the adapter to gain access
to the coupling. Rotate the coupling in relation to the unfastened
shaft, allowing the coupling to seek a normal resting position.
