3  Servomotor Specifications and Dimensional Drawings
3.5.2  SGMSH Servomotors (3000 min
-1
) With Low-backlash Gears
3-30
* 1.  The maximum input motor speed of the gears is 4000 
min
-1
.
* 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.
