 For 3,000-r/min Servomotors
 
*1. It is maximum allowable torque for decelerator. Take a caution not to exceed this value.
Note 1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor combined with the Decelerator is IP44. (Excluding decelerator 
and servo motor connecting parts.)
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).
Backlash: 15 Arcminutes Max.
