5-1 Installation of servomotor
CAUTION
1. Do not hold the cables, axis or detector when transporting the servomotor.
Failure to observe this could lead to faults or injuries.
2. Securely fix the servomotor to the machine. Insufficient fixing could lead to
the servomotor deviating during operation. Failure to observe this could
lead to injuries.
3. When coupling to a servomotor shaft end, do not apply an impact by
hammering, etc. The detector could be damaged.
4. Never touch the rotary sections of the servomotor during operations. Install
a cover, etc., on the shaft.
5. Do not apply a load exceeding the tolerable load onto the servomotor shaft.
The shaft could break.

5-1-2 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 installation on the
servomotor cannot be changed.
CAUTION
Never hammer the end of the shaft
during assembly.
5-1-3 Installation direction
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 (lead-in wires) face downward. When the servomotor is not installed in the standard direction,
refer to section "5-1-5 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.
