The figure below shows typical PTC sensor resistance values as a function of the
motor operating temperature.
The figure below shows typical KTY84 sensor resistance values as a function of the
motor operating temperature.
It is possible to adjust the motor temperature supervision limits and select how the
drive reacts when overtemperature is detected.
