3.1.1 Ratings and Specifications
(3) Overload Characteristics
The overload detection level is set under hot start conditions at a servomotor surrounding air temperature of
40°C.
Note: Overload characteristics shown above do not guarantee continuous duty of 100% or more output. Use a servomotor
with effective torque within the continuous duty zone of Torque-Motor Speed Characteristics.
(4) Allowable Load Moment of Inertia at the Motor Shaft
The rotor moment of inertia ratio is the value for a servomotor without a gear and a holding brake.
