Notice: 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.
Refer to: p0625
Notice: 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 resistance
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 (models 2 and 3).
Description: Displays the stator iron temperature of the motor temperature model (models 2 and 3).
