CAUTION
(1) When mounting a pulley to the servo motor with a key shaft, use the screw hole in the shaft end. To fit
the pulley, first insert a double-end stud into the screw hole of the shaft, put a washer against the end
face of the coupling, and insert and tighten a nut to force the pulley in.
(2) For the shaft without a key, use a friction coupling or the like.
(3) When removing the pulley, use a pulley remover to protect the shaft from hard load and or impact.
(4) To ensure safety, fit a protective cover or the like on the rotary area, such as the pulley, mounted to the
shaft.
(5) When a threaded shaft end part is needed to mount a pulley on the shaft, please contact your local sales
office.
(6) The direction of the encoder on the servo motor cannot be changed.
