6. HG-MR SERIES/HG-KR SERIES
6 - 4
Note 1. When the power supply voltage drops, the output and the rated speed cannot be guaranteed.
2. If the load to motor inertia ratio exceeds the indicated value, contact your local sales office.
3. Refer to the dimensions for the geared servo motor.
4. Except for the shaft-through portion. IP classifies the degrees of protection provided against the intrusion of solid objects and
water in electrical enclosures.
5. In the environment where the servo motor is exposed to oil mist, oil, or water, the servo motor of the standard specifications
may not be usable. Please contact your local sales office.
6. The following figure shows the vibration directions. The value is the one at the part that indicates the maximum value (normally
the opposite to load-side bracket). When the servo motor stops, fretting is likely to occur at the bearing. Therefore, suppress
the vibration to about half of the permissible value. Note that this does not apply to the geared servo motor.

7. V10 indicates that the amplitude of a single servo motor is 10 μm or less. The following figure shows the servo motor mounting
position for measurement and the measuring position.

8. The following shows permissible load for the shaft. Do not subject the shaft to load greater than the value in the specifications
list. The value assumes that the load is applied independently.

9. For the geared servo motor, the reducer area is IP44-equivalent.
10. Refer to section 6.6 for the geared servo motor.
11. The servo motors with an oil seal are also available. For details, contact your local sales office.
