Notices for maintaining accuracy
To maintain accuracy, observe the following notices when using the motor.
Use the product in an appropriate environment.

The environmental conditions for our accuracy measurement are a temperature of
23±0.3
℃
and relative humidity of 50
％ .
When using the motor in a device that
requires high accuracy positioning control, please take into account the stiffness of the
mechanism for temperature change of up to ±3 ˚C, the coefficient of expansion for
each part, external vibration, etc.
Periodically rotate the output shaft at least 90 ˚.

In order to prevent uneven wear due to the cross roller bearing grease running out, for
devices used in operation environments with fine operations, periodically rotate the
output shaft at least 90 ˚ in order to maintain accuracy.
Mounting direction check

The mounting condition for our accuracy measurement is to have the output shaft
facing up.
When using the motor with the output shaft not facing up, contact us for more
information.
Accuracy cannot be guaranteed in environments subject to vibration
and impact.

The resistance to vibration and impact in the specifications table are standard values
for the vibration and impact that occur while transporting or mounting the motor. While
transporting or mounting the motor, do not subject the motor to any vibration or impact.
In order to use the motor with high accuracy, use it in an environment with no impact
or vibration.
