Using a KTY sensor, the inverter monitors the motor temperature and the sensor itself for
wire-break or short-circuit:
● Temperature monitoring:
The inverter uses a KTY sensor to evaluate the motor temperature in the range from -48°
C ... +248° C.
Use the p0604 or p0605 parameter to set the temperature for the alarm and fault
threshold.
– Overtemperature alarm (A07910):
– Overtemperature fault (F07011):
● Sensor monitoring (A07015 or F07016):
– Wire-break:
– Short-circuit:
Temperature switch
The inverter interprets a resistance ≥ 100 Ω as being an opened temperature switch and
responds according to the setting for p0610.
PTC sensor
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.

- 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 < 50 Ω as a short-circuit and outputs the alarm
A07015. After 100 milliseconds, the inverter changes to the fault state with F07016.
