7 Overload Characteristics
The overload detection level is set under hot start* conditions at a servomo-
tor surrounding air temperature of 40
°
C.
* 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 follow-
ing servomotors.
