Siemens SINAMICS G115D User Manual

Pt1000 sensor
Using a Pt1000 sensor, the converter monitors the motor temperature and the sensor itself
for wire breakage and/or short-circuit:
• Temperature monitoring:
Using a Pt1000 sensor, the converter 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):
- motor temperature > p0604 and p0610 = 0
– Overtemperature fault (F07011):
The converter responds with a fault in the following cases:
- motor temperature > p0605
- motor temperature > p0604 and p0610 ≠ 0
• Sensor monitoring (A07015 or F07016):
– Wire-break:
The converter interprets a resistance > 2120 Ω as a wire-break and outputs the alarm
A07015. After 100 milliseconds, the converter changes to the fault state with F07016.
– Short-circuit:
The converter interprets a resistance <603 Ω as a short-circuit and outputs the alarm
A07015. After 100 milliseconds, the converter changes to the fault state with F07016.
