OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User’s Manual
*1 The value is the allowable continuous output torque of the Decelerator. Do not exceed this value.
*2 The value is the maximum allowable rotation speed of the Decelerator. Do not exceed the maximum motor shaft rotation 
speed of 4,500 r/min.
*3 The value is the maximum allowable torque of the Decelerator. Do not exceed this value.
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 models have a straight shaft. A model with a key and tap is indicated with J at the end of the model 
number (the suffix shown in the box).
