6 HK-KT SERIES
6.6 Geared servo motor
■With shaft-output type gear reducer for high precision applications, flange mounting: G7
*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. Refer to the following for the shaft length.
