Note: 1. When the power supply voltage drops, we cannot guarantee the output and rated speed.
2. If the load inertia moment ratio exceeds the indicated value, please consult us.
3. When the servo motor is equipped with electromagnetic brake, refer to section 14.8.When the servo motor is equipped with
reduction gear, please consult us.
4. The regenerative brake duty indicated is the permissible duty when the servo motor running without load at the rated speed is
decelerated to a stop. When a load is connected, the value in the table is multiplied by 1/(m 1), where m load inertia
moment/motor inertia moment. At the speed higher than the rated, the permissible number of times is in inverse proportion to
the square of (running speed/rated speed). When the running speed varies frequently or when the regenerative mode
continues as in vertical feed, calculate regenerative heat generated during operation. Provisions must be made to keep this
generated heat below the permissible value.
5. If the effective torque is within the rated torque range, there are no restrictions on the regenerative duty. Note that the
recommended load inertia moment ratio is 15 times or less.
6. Except for the shaft-through portion and connector end.
7. When the equipment is to be used in places where it is subjected to oil and/or water, such as on machine field sites, optional
features apply to the equipment. Please contact.
8. When the servo motor is provided with the reduction gear, the protection type of the reduction gear section is IP44.
9. At the load inertia moment ratio of 5 times or less, there are no restrictions on the regenerative duty if the effective torque is
within the rated torque range.
10. The regenerative brake duty of the 400W or less servo amplifier may vary under the influence of the power supply voltage
because of the large ratio of the energy for charging the electrolytic capacitor in the servo amplifier.
