The rated current (produced continuously) will be reduced to
the value stated in the mentioned table and indicated in Full
load current and Drive size parameters.
Automatically, the overload function (FUNCTION\Overload
control), is set to the following:
Enable overload = ON
Overload mode = I2t motor
Overload time = 60s
Full load current= American
Pause time = 540s
T current lim = 150%
Overload current = 150%
T current lim+ = 150%
Base current = 100%
T current lim - = 150%
If the size “American”is selected, the parameter Overcurrent thr [584] will be set at 160%

If the converter is reconfigured as “Standard”, these parameters and the continuous current
limit take the values corresponding to the previous configuration (overload disabled) and the
parameter Overcurrent thr [584] returns to 110%.

The factor function consists of two factors - the dimension factor and the face value factor. Both factors are de-
fined as fractions. The dimension factor is used to specify the drive speed in a dimension related to the machine
concerned, e.g. kg/h or m/min. The face value factor is used to increase the resolution.
See the calculation examples given beow.
