Exclusive specifications
■With flange-output type gear reducer for high precision applications, flange mounting: G5
*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 radial load points of high-precision gear reducers are as follows.
*4 The value in ( ) indicates the flange dimensions.
