6.21 Motor temperature monitoring using a temperature sensor
Pt1000 sensor
Using a Pt1000 sensor, the inverter monitors the motor temperature and the sensor itself for
wire breakage and/or short-circuit:
● Temperature monitoring:
Using a Pt1000 sensor, the inverter evaluates the motor temperature in the range from -
48 °C ... +248 °C.
You set the temperature for the alarm and fault thresholds using parameters p0604 and
p0605.
– Overtemperature alarm (A07910):
– Overtemperature fault (F07011):
● Sensor monitoring (A07015 or F07016):
– Wire-break:
– Short-circuit:

- motor temperature > p0604 and p0610 = 0
The inverter responds with a fault in the following cases:
- motor temperature > p0605
- motor temperature > p0604 and p0610 ≠ 0
The inverter interprets a resistance > 2120 Ω as a wire-break and outputs the alarm
A07015. After 100 milliseconds, the inverter changes to the fault state with F07016.
The inverter interprets a resistance < 603 Ω as a short-circuit and outputs the alarm
A07015. After 100 milliseconds, the inverter changes to the fault state with F07016.

Mot_temp_mod 2 / sensor alarm threshold (factory setting 130° C)
For monitoring the motor temperature using KTY84/Pt1000.
Mot_temp_mod 1/2 / sensor threshold and temperature value (factory setting: 145° C)
For monitoring the motor temperature using KTY84/Pt1000.
Motor overtemperature response (factory setting: 12)
Determines the inverter behavior when the motor temperature reaches the alarm
threshold p0604.
0: Alarm (A07910), no fault
1: Alarm A07910 and fault F07011
