to Estimated .
0 … 300 °C Temperature rise. 1 = 1 °C
31.14 Mot therm time Defines the thermal time constant for the motor thermal
protection model (i.e. time inside which the temperature has
reached 63% of the nominal temperature). See the motor
manufacturer's recommendations.
The motor thermal protection model is used when parameter
31.02 Mot temp1 src is set to Estimated .
