3-2-1 Cautions for mounting load (prevention of impact on shaft)
1) When using the servomotor with keyway, use the screw hole
at the end of the shaft to mount the pulley onto the shaft. To
install, first place the double-end bolt into the shaft screw
holes, contact the coupling end surface against the washer,
and press in as if tightening with a nut. When the shaft does
not have a keyway, use a frictional coupling, etc.
2) When removing the pulley, use a pulley remover, and make
sure not to apply an impact on the shaft.
3) Install a protective cover on the rotary sections such as the
pulley installed on the shaft to ensure safety.
4) The direction of the detector installation on the servomotor cannot be changed.
CAUTION
Never hammer the end of the shaft
during assembly.
3-2-2 Installation direction
1) There are no restrictions on the installation direction. Installation in
any direction is possible, but as a standard the servomotor is
installed so that the motor power supply wire and detector cable
cannon plugs face downward. Installation in the standard direction is
effective for preventing dripping. If the motor is not to be installed in
the standard direction, caution is required in particular to oil and
water measures. Refer to section "3-1-2 Oil and waterproofing
measures" and take the appropriate measures.
The brake plates may make a sliding sound when a servomotor with
magnetic brake is installed with the shaft facing upward, but this is
not a fault.
2) In a situation where the detector cannon plug cannot be wired in the
same direction as the power supply wire, the motor is prepared so that
the detector installation direction can be changed in 90
°
increments, as
shown in the drawing at the right. (Special compatibility) Designate the
motor direction when ordering. The user must not remove the detector.
