2.2 Typical short term overload limits
The maximum percentage overload limit changes depending on the induction motor only. Variations in motor rated current, motor rated power factor
and motor leakage inductance all result in changes in the maximum possible overload. The exact value for a specific motor can be calculated using
the equations detailed in Menu 4 in the Commander SK Advanced User Guide.
Table 2-1 Typical overload limits for size 2 to 5
Table 2-2 Typical overload limits for size 6
Generally the drive rated current is higher than the matching motor rated current allowing a higher level of overload than the default setting as
illustrated by the example of a typical 4 pole motor.
The time allowed in the overload region is proportionally reduced at very low output frequency on some drive ratings.
The maximum overload level which can be attained is independent of the speed.
