3-3 Decelerator Specifications
3
For 1,500-r/min Servomotors
*1. The value is the allowable continuous output 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).
4. The standard shaft type is a straight shaft. A model with a key and tap is indicated with “J” at of the model num-
ber.
5. Take care so that the surface temperature of the Decelerator does not exceed 70°C.
