14.11.16.9 Motor protection with temperature sensor Pt100
Overview
To protect the motor against overtemperature, the converter can evaluate the Pt100 sensor.
Requirement
You have set the temperature oset via parameter p0624.
With this setting, you correct a systematic temperature deviation, e.g. caused by the
resistance of the measuring sensor connecting cable.
Description of function
With a Pt100 sensor, the converter evaluates the motor temperature in the range -48°C to
+248°C.
You set the temperature for the alarm and fault thresholds with parameters p0604 and
p0605, respectively.
• Alarm overtemperature (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
• Wire break:
After 100milliseconds, the converter transitions into fault state F07016.
• Short-circuit:
After 100milliseconds, the converter transitions into fault state F07016.
