Motor temperature monitoring using a temperature sensor
Connecting the temperature sensor
You can use one of the following sensors to protect the motor against overtemperature:
● Temperature switch (e.g. bimetallic switch)
● PTC sensor
● KTY84 sensor
Connect the temperature sensor of the motor to terminals
14 and 15 of
the inverter.
Set response to excess motor temperature
If you use a temperature switch or PTC sensor, set the response to excess motor
temperature via P0610 as follows:
● p0610 = 0
– Warning A07910,
– No shutdown
● p0610 = 1, p0610 = 2, p0610 = 12
– Warning A07910
– Shutdown with fault F07011
If you use a KTY84 sensor, set the temperature for the warning or fault threshold via p0604
or p0605.
● Monitoring via p0604: Response as per the setting in p0610
● Monitoring via p0605: Shutdown with fault as soon as the set threshold is exceeded.
For details, please refer to the List Manual.
The inverter interprets a resistance ≥ 100 Ω as being an opened temperature switch and
responds according to the setting for p0610.
The inverter interprets a resistance > 1650 Ω as being an overtemperature and responds
according to the setting for p0610.
The inverter interprets a resistance < 20 Ω as being a short-circuit and responds with alarm
A07015. If the alarm is present for longer than 100 milliseconds, the inverter shuts down with
fault F07016.
