Motor temperature sensing

Temperature sensors
The motor temperature is sensed using temperature sensors integrated in the motor
windings. The sensors used are selected as standard from the following four different sensor
types:
● PTC
● KTY84
● PT100/PT1000
● Bimetallic sensor with NC contact (abbreviated, "bimetal NC contact")
