* Derating is applied to these drives at low output frequencies. Please contact the 
supplier of the drive for more information if the application requires significant torque, at 
or close to zero speed for extended periods of time or if prolonged periods of overload 
(>100%) are required.
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. Typical values are shown in the 
table below:
