1-1-3 Cautions for mounting load (prevention of impact on shaft)
[1] When using the servomotor with key way, use the screw hole at the end of the shaft to mount the pulley
onto the shaft. To install, first place the double-end stud 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
key way, 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 installed on the servomotor cannot be changed.
1-1-4 Installation direction
[1] There are no restrictions on the installation direction. Installation in any direction is possible, but as a
standard the motor is installed so that the motor power line and detector cable cannon plugs (lead-in
wires) face downward. Installation in the standard direction is effective against dripping. Measure to
prevent oil and water must be taken when not installing in the standard direction. When the motor is not
installed in the standard direction, refer to section "1-1-8 Oil/water standards" 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.
Never hammer the end of the shaft during assembly.
