* 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.
2.1.1 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 Menu 4 in the Advanced User Guide.
Typical values are shown in the table below for closed loop vector (VT) and open loop (OL) modes:

Table 2-5 Typical overload limits for size 0 to 5

Operating mode
Normal Duty overload with motor rated current = drive rated current
Heavy Duty overload with motor rated current = drive rated current
Heavy Duty overload with a typical 4 pole motor

Table 2-6 Typical overload limits for size 6

Operating mode
Normal Duty overload with motor rated current = drive rated current
Heavy Duty overload with motor rated current = drive rated current
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.
NOTE
The maximum overload level which can be attained is independent of the speed.
