.
* 2. Output torque and motor speed produce the following trends in efficiency. Values in the table are at
the rated motor speed.
Note: 1. For the shaft center allowable radial load, refer to the servomotor dimensional drawing.
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.
