Function:
No No external fan is required, i.e. the motor is derated at low
speed.
Yes Applies an external motor fan (external ventilation), so no de-
rating 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. 1-24). If the motor current exceeds nominal
current, the operation time still decreases as if no fan were in-
stalled.
Function:
Select the input to which the thermistor (PTC sensor) should be
connected. An analog input option [1] or [2] cannot be selected
if the analog input is already in use as a reference source (se-
lected in par. 3-15
2 or 3-17 Reference Source 3).
This parameter cannot be adjusted while the motor is running.
