8 - 4
Note 1. When the power supply voltage drops, the output and the rated speed cannot be guaranteed.
2. If the load inertia moment ratio exceeds the indicated value, contact your local sales office.
3. To configure the absolute position detection system, always connect the battery and absolute position storage unit to the servo
amplifier. For details of the battery, refer to each servo amplifier instruction manual. For details of the absolute position storage
unit, refer to section 6.3.
4. Shaft-through portion of the rotor and the connector area are excluded. IP classifies the degrees of protection provided against
the intrusion of solid objects and water in electrical enclosures.
5. In the environment where the direct drive motor is exposed to oil mist, oil, and water, a standard specification direct drive
motor cannot be used. Provide measures to prevent dust and/or water on the machine side.
6. The vibration direction is as shown below. The indicated values are the maximum values. When the direct drive motor stops,
fretting is likely to occur at the bearing. Therefore, suppress the vibration to about the half of the permissible value.

7. V10 indicates that the amplitude of a direct drive motor alone is 10 μ m or less. The following figure shows the direct drive
motor mounting position for measurement and the measuring position.

8. Axial and moment loads, which are applied to the direct drive motor's rotor (output shaft) during operation, can be calculated
as below. The axial and moment loads must be maintained to be equal to or below the permissible value.
F (external force)
Axial load
= F + load mass
L F (external force)
Axial load
= F + load mass
Moment load
= F × L

9. The value inside ( ) applies when the torque is increased. The rated torque and the maximum torque can be increased by
changing the servo amplifier.
Refer to section 8.2 for the combinations.
10. Follow the restrictions in section 2.10 when using this product at altitude exceeding 1000 m and up to 2000 m above sea level.
11. Absolute accuracy changes depending on the mounting condition of the load and the surrounding environment.
