Typical short term overload limits
The maximum percentage overload limit changes depending on the selected motor. Variations in
motor rated current, motor 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 the Parameter Reference Guide. Typical values are shown in the table below:
Table 2-6 Typical overload limits
Generally the drive rated current is higher than the matching motor rated current allowing a higher
level of overload than the default setting. The time allowed in the overload region is proportionally
reduced at very low output frequency on some drive ratings.
