SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
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.
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: Reference value for the identification of the stator resistance every time the drive is powered up.
Dependency: The measurement of the reference value is activated by the automatic calculation (p0340 = 1, 2), if the following
conditions apply:
- the motor temperature is at this instant in time less than 30 °C (r0035).
- a KTY temperature sensor is not being used (p0601).
Refer to: p0621, r0623
Note: The reference value to identify the stator resistance is determined at the first identification. This must be realized
when the motor is in a cold state, as the value refers to the ambient temperature p0625. The feeder cable resis-
tance should be entered into p0352 before the measurement.
The result must be saved after the first measurement so that the reference is available after the CU has a powered
up. When changing p0350 or p0352, the reference value p0629 should be re-determined.
Description: Displays the ambient temperature of the motor temperature model.
Description: Displays the stator core temperature of the motor temperature model.
