4.2.2 Mechanical Characteristics
The mechanical characteristics of the Servomotor are described here.
Allowable Radial Load, Allowable Thrust Load
The output shaft allowable loads for Servomotors are shown below.
Conduct mechanical design so that the thrust loads and radial loads do not exceed the
following values.
