5. SPECIFICATIONS
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.This ratio is the load inertia moment ratio to the inertia moment of the servo motor. If the load inertia moment ratio exceeds the
indicated value, please consult us. When the servo motor is equipped with reduction gear or electromagnetic brake, refer to the
corresponding outline dimension drawing. For the EN Standard- and UL/C-UL Standard-compliant models, 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.
6.Except for the shaft-through portion and connector end.
7.In the environment where the servo motor is exposed to oil mist, oil and/or water, the servo motor of the standard specifications
may not be usable. Contact us.
8.IP54 for the EN Standard-compliant model.
9.Except the connector section.
10.Values for use of the supplied regenerative brake unit (regenerative resistor) are indicated in the case of the 11k to 22kW servo
amplifiers. Values for use of the supplied regenerative brake unit (regenerative resistor).
11.80%ED at low noise.
80%ED: Indicates the condition in which operation time at read torque accounts for 80% and the other no-load time accounts for
20% in a single operation cycle.

12.When the servo motor is provided with the reduction gear, the protection type of the reduction gear section is IP44.
13.Consult us since they may not be connected depending on the production period of the servo amplifier.
14.Value applicable when the regenerative option is cooled by a cooling fan.
15.The regenerative brake duty of the 600W 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.
