Servomotor Specifications and Dimensional Drawings
When using a servomotor with oil lubrication, the servomotor can be installed horizontally onto the shaft.
Contact your Yaskawa representative for more information regarding the sliding installation of a servomotor.
Note: 1. Output torque and motor speed produce the following trends in efficiency. Values in the table are
at the rated motor speed.
2. The no-load torque for a servomotor with gears is high immediately after the servomotor starts,
and it then decreases and becomes stable a few minutes later. This is a common phenomenon
caused by grease being circulated in the gear and not by a faulty gear.
