The gear output torque is expressed by the following formula.
*1.
Gear output torque = Servomotor output torque
The gear efficiency depends on operating conditions such as the output torque, motor speed, and temperature.
The values in the table are typical values for the rated torque, rated motor speed, and a surrounding air tem-
perature of 25°C. They are reference values only.
Use the Servomotor at an effective load ratio of 85% or less. The values in the table take the effective load ratio

into consideration.
The rated motor speed calculated at the motor shaft is 2,000 min
*3.
The maximum motor speed calculated at the motor shaft is 4,500 min
*4.
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. Other specifications are the same as those for Servomotors without Gears.

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.
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.
