Note 1. The reduction gear inertia indicates the Servomotor shaft conversion value.
Note 2. The enclosure rating for Servomotors with reduction gears is IP44.
Note 3. The maximum momentary torque values marked by asterisks are the maximum allowable
torque for the reduction gears. Use torque limits so that these values are not exceeded.
Note 4. The allowable radial loads are measured in the center of the shaft.
