4. For example The thermal capacity level of the motor reduces from 100 at 40 C to 85 at 50 C Therefore the motor can be loaded maximum to 9290 of its rated load at 50 C Manual reduction may be needed if other reduction multiplier than presented in the table above are required Output power reduction is done by setting the value 40 C to parameter motor ambient temperature and calculating the temperature reduction directly to nominal current When multiplier is calculated this way it must be applied to trip class time as well IS TFLC For example Motor data sheet specifies that in 60 C motor be loaded maximum of 75 of the nominal Thus motor ambient temperature is set to 40 C and when setting the nominal current the rated motor current is derated nominal current 0 75 When nominal current is derated trip class parameter is defined with the same factor It should also be considered that other parameter s i e protection function trip and alarm levels referring to nominal current are effected relatively 10 Stall Protection Stall protection is used to protect the driven mechanical system from jams and excessive overloads Under such conditions the motors have to be switched off in good time and reported to avoid undue mechanical and thermal stress on the motor and the installation This protection function is active only after the motor has successfully started or after parameterised motor star
