12. SERVO MOTOR
12.2.2 Precautions for load remove
POINT
During assembling, never hit the shaft end of the servo motor by a hammer,
etc. It may damage the encoder.
(1) When mounting a pulley to the servo motor shaft with a keyway, use the screw hole on the shaft end. To fit
the pulley, first insert a double-end stud into the screw hole on 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 keyway, use a friction coupling or the like.
(3) When removing the pulley, use a pulley remover to protect the shaft from hard load or impact.
(4) To ensure safety, fit a protective cover or the like on the rotating part, 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.
(7) For installation of the servo motor, use spring washers, etc. and fully tighten the bolts so that they do not
become loose due to vibration.
