5.2.4 Servomotor Overload Protection Characteristics
The overload detection level is set for hot start conditions with a Servomotor surrounding air tem-
perature of 40
°
C.
Note: The above overload protection characteristics do not mean that you can perform continuous duty operation
with an output of 100% or higher. Use the Servomotor so that the effective force remains within the continu-
ous duty zone given in
5.2.3 Force-Motor S peed Characteristics on page 5-7.
