t overload
[%]
Sets the alarm threshold for the I
2
t power unit over‐
load.
Factory setting: 95
7.24 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 converter.
For more information about motor interface, see Interface description - X2 (Page74).

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 converter cannot detect a motor overtemperature condition.
• Connect the KTY sensor with the correct polarity.
