15 Overload Characteristics
The overload detection level is set under hot start* conditions at a servomotor surrounding air
temperature of 40
°C (104°F).
* A hot start indicates that both the SERVOPACK and the servomotor have
run long enough at the rated load to be thermally saturated.
Note: The overload protection characteristics of A, B, and C in the figure
are applicable when the SERVOPACK is combined with one of the
following servomotors.
