6.21 Motor temperature monitoring using a temperature sensor

6.21 Motor temperature monitoring using a temperature sensor
You can use one of the following sensors to protect the motor against overtemperature:
● Temperature switch (e. g. bi-metal switch)
● PTC sensor
● KTY 84 sensor
● PT1000 Sensor
Connect the motor's temperature sensor through the motor output cable on the Power
Module.

KTY84 sensor
NOTICE
Overheating of the motor due to KTY sensor connected with the incorrect polarity
If a KTY sensor is connected with incorrect polarity, the motor can become damaged due to
overheating, as the inverter cannot detect a motor overtemperature condition.
• Connect the KTY sensor with the correct polarity.
