Safety instructions
Instructions for the protection of the servo motor shaft
● When mounting a pulley to the servo motor shaft provided with a keyway, use the screw
hole in the shaft end (refer fig. 2-3). 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.
Under no circumstances must you use a hammer for installation work on the servo motor
shaft.
● For servo motors with the shaft without a keyway, use a friction coupling or the like.
● When removing the pulley, use a pulley remover to protect the shaft or the motor from impact.
● The orientation of the encoder on the servo motor cannot be changed.
b
CAUTION:
●
Do not hold the cable, shaft or encoder to carry the servo motor. Otherwise, a fault
or injury may occur.
● Securely fix the servo motor to the machine. If fixed insecurely, the servo motor
will come off during operation, leading to injury.
● When coupling the shaft end of the servo motor, do not subject the shaft end to
impact, such as hammering. The encoder may become faulty.
● Secure the motor shaft and rotating parts against access through appropriate
covers.
● Do not subject the servo motor shaft to more than the permissible load. Otherwise,
the shaft may break, leading to injury.
