NTC temperature sensor
The V-412.xx6211E1 is equipped with an NTC temperature sensor for monitoring the coil
temperature. The electrical resistance of the NTC temperature sensor decreases considerably
as temperature increases. The controller must cut the power supply to the motor (switching
threshold: 295
Ω
) when the critical temperature (130 °C) is reached.
