Two temperature sensor types are integrated:
Temperature sensors KTY 84 are ESD components. When
delivered, they are short-circuited with a terminal.
Temperature sensors of the same type are always installed in one particular motor.
The type of temperature sensor installed is stamped on the rating plate.

Connection
Response temperature
The resistance change is proportional to the winding temperature change. The temperature
characteristic is taken into account in the closed-loop control.
