NB!
Check that the chosen supply voltage follows the specification of the used thermistor element.
Select Electronic Overload Warning 1-4, to activate a warning on the display when the motor is overloaded.
Select Electronic Overload Trip 1-4 to trip the frequency converter when the motor is overloaded.
Program a warning signal via one of the digital outputs. The signal appears in the event of a warning and if the frequency converter trips (thermal warning).
Electronic Overload functions 1-4 will calculate the load when the set-up where they were selected is active. For example Electronic Overload 3 starts calculating
when setup 3 is selected. For the North American market: The Electronic Overload functions provide class 20 motor overload protection in accordance with NEC.

F-11 Motor External Fan
Option:
[0] * No
[1] Yes
40
Function:
No external fan on motor, i.e. the motor is derated at low speed.
Applies an external motor fan (external ventilation), so no derating of the motor is required at low speed.
The graph below is followed if the motor current is lower than nominal motor current (see par. P-03 Motor
Current). If the motor current exceeds nominal current, the operation time still decreases as if no fan were
installed.
