5.2 Specifications and Ratings
5.2.6 Ratings of Servomotors with Gears
Note: 1. The gears that are mounted to Yaskawa Servomotors have not been broken in.
2. The no-load torque for a Servomotor with a Gear is high immediately after the Servomotor starts, and it
3. Contact your Yaskawa representative for information on Servomotor with Gears with a rated output of
4. Other specifications are the same as those for Servomotors without Gears.

* The moment of inertia for the Servomotor and gear is the value without a holding brake. You can calculate the
moment of inertia for a Servomotor with a Gear and Holding Brake with the following formula.
5-10
Break in the Servomotor if necessary. First, operate the Servomotor at low speed with no load. If no prob-
lems occur, gradually increase the speed and load.
then decreases and becomes stable after a few minutes. This is a common phenomenon caused by grease
circulation in the gears and it does not indicate faulty gears.
1.5 kW or higher.
The SERVOPACK speed control range is 1:5,000. If you use Servomotors at extremely low speeds
-1
(0.02 min or lower at the gear output shaft), if you use Servomotors with a one-pulse feed refer-
ence for extended periods, or under some other operating conditions, the gear bearing lubrication
may be insufficient. That may cause deterioration of the bearing or increase the load ratio.
Contact your Yaskawa representative if you use a Servomotor under these conditions.
