SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Description: Defines the ambient temperature of the motor for calculating the motor temperature model.
Note: The parameters for stator and rotor resistance (p0350, p0354) refer to this temperature.
If the thermal I2t motor model is activated for permanent-magnet synchronous motors (refer to p0611), p0625 is
included in the model calculation if a temperature sensor is not being used (see p0601).
Description: Defines the rated overtemperature of the stator core referred to the ambient temperature.
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
Refer to: p0625
Caution: When selecting a standard induction motor listed in the catalog (p0300 > 100, p0301 > 10000), this parameter is
automatically preassigned and is write protected. Information in p0300 should be carefully observed when removing
write protection.
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
Description: Defines the rated overtemperature of the stator winding referred to the ambient temperature.
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
Refer to: p0625
Caution: When selecting a standard induction motor listed in the catalog (p0300 > 100, p0301 > 10000), this parameter is
automatically preassigned and is write protected. Information in p0300 should be carefully observed when removing
write protection.
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
Description: Defines the rated overtemperature of the squirrel cage rotor referred to ambient temperature.
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
