6.19 Motor temperature monitoring using a temperature sensor
Description
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. The inverter reduces its current limit.
2: Alarm A07910 and fault F07011.
12: Alarm A07910 and fault F07011. For use of the thermal motor model in parallel to
the temperature sensor: After switching off the supply voltage, the inverter saves the
most-recently calculated difference to the ambient air temperature. After switching the
supply voltage on again, the thermal motor model starts with 90% of the previously
saved difference temperature.
