6-1-3 Precautions for mounting load (Preventing impact on shaft)
(1) When using the servomotor with keyway, use the screw
hole on the end of the shaft to mount the pulley onto the
shaft. When mounting, insert a double-end stud into the
shaft's screw hole, and contact a washer against the end
of the coupling. Push in so as to tighten with the nut. Use a
friction joint for a shaft which does not have a keyway.
(2) When removing the pulley, use a pulley remover, and take
care not to apply impact on the shaft.
(3) Provide a protection cover, etc., to ensure safety at the
rotating sections, such as the pulley mounted on the shaft.
(4) The direction of the detector mounted on the servomotor
cannot be changed.

Never tap the shaft end with a hammer
when assembling, etc.
6-1-4 Installation direction
(1) The servomotor can be installed in any direction without limit,
but as a standard, the cannon plugs (led out wires) of the
motor power supply cable and detector cable should face
downward. Installing in the standard direction is effective for
drip-proofing. If the servomotor is not to be installed in the
standard direction, special caution must be taken for oil and
waterproofing. Refer to section "6-2-5 Oil and waterproofing
measures" and provide appropriate measures. When installing
the servomotor with magnetic brakes with the shaft facing
upward, the sound of the brake plates sliding may be heard.
This is not an abnormality.

6-1-5 Oil and waterproofing measures
(1) A format based on IEC Standards (IP types) is used as the motor
protective format. However, these Standards are short-term performance
specifications. They do not guarantee continuous environmental
protection characteristics. Measures such as covers, etc., must be
provided if there is any possibility that oil or water will fall on the motor, or
the motor will be constantly wet and permeated by water. Note that the
motor’s IP-type is not indicated as corrosion-resistant.
(2) When a gear box is installed on the servomotor, make sure that the oil
level height from the center of the shaft is higher than the values given below. Open a breathing
hole on the gear box so that the inner pressure does not rise.
