*1. The value is the allowable continuous output torque of the Decelerator. Take care so that this value is not exceeded.
*2. The value is the maximum allowable torque of the Decelerator. Take care so that this value is not exceeded.
Note:
1. The Decelerator inertia is the Servomotor shaft conversion value.
2. The protective structure rating of the Servomotor with the Decelerator is IP44.
3. The Allowable radial load column shows the values obtained at the center of the shaft (T/2).
