CAUTION
1. Do not hold the cables, axis or detector when transporting the motor. Failure to
observe this could lead to faults or injuries.
2. Securely fix the motor to the machine. Insufficient fixing could lead to the
motor 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 motor 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. Failure to observe this could lead to injuries.
6. Do not connect or disconnect any of the connectors while the power is ON.

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.
CAUTION
Never hammer the end of the shaft
during assembly.
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 "1-1-6 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.

1-1-5 Shaft characteristics
There is a limit to the load that can be applied on the motor shaft. Make sure that the load applied on the
radial direction and thrust direction, when mounted on the machine, is below the tolerable values given
below. These loads may affect the motor output torque, so consider them when designing the machine.

CAUTION
1. Use a flexible coupling when connecting with a ball screw, etc., and keep the
shaft core deviation to below the tolerable radial load of the shaft.
2. When directly installing the gear on the motor shaft, the radial load increases
as the diameter of the gear decreases. This should be carefully considered
when designing the machine.
3. When directly installing the pulley on the motor shaft, carefully consider so
that the radial load (double the tension) generated from the timing belt tension
is less than the values shown in the table above.
4. In machines where thrust loads such as a worm gear are applied, carefully
consider providing separate bearings, etc., on the machine side so that loads
exceeding the tolerable thrust loads are not applied to the motor.
5. Do not use a rigid coupling as an excessive bending load will be applied on
the shaft and could cause the shaft to break.
