*1 The moment inertia value is converted into the equivalent value on the servo motor shaft of the servo motor combined with the gear
reducer (and an electromagnetic brake).
*2 Do not subject the shaft to loads greater than the indicated value. Each value in the table indicates the load to be applied independently.
*3 The permissible radial loads in the table are the values at the center of the gear reducer output shaft. Refer to the following for the shaft
length.
