The thermistor cut-out value is > 3 k
Ω
.
Integrate a thermistor (PTC sensor) in the motor for winding protection.
Motor protection can be implemented using a range of techniques: PTC sen-
sor in motor windings; mechanical thermal switch (Klixon type); or Electronic
Thermal Electronic Thermal Overload.
Using a digital input and 24 V as power supply:
Example: The frequency converter trips when the motor temperature is too
high.
Parameter set-up:
Set par. F-10
Electronic Overload

Using a digital input and 10 V as power supply:
Example: The frequency converter trips when the motor temperature is too
high.
