3-3 Decelerator Specifications
3
Specifications
*1. Keep the maximum rotation speed at 4,500 r/min or less.
*2. With the R88G-HPG11B05100B(J), cold start efficiency may be reduced if a 50-W motor is used. (When operation
is first started in the morning while the Decelerator temperature is low, the viscosity of the lubricant inside the
Decelerator will be higher. As operation continues and the Decelerator temperature rises, the viscosity of the
lubricant will be lowered and efficiency will improve.)
Note1. The values inside parentheses ( ) are for 100-V Servomotors.
Note2. The Decelerator inertia is the Servomotor shaft conversion value.
Note3. The protective structure for Servomotors with Decelerators satisfies IP44.
Note4. The allowable radial load is the value at the T/2 position.
Note5. The standard models have a straight shaft. Models with a key and tap are indicated with "J" at the end of
the model number (the suffix in the box).
