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.
- motor temperature model 1 (I2t, p0612.0 = 1):
The following applies for firmware version < 4.7 SP6 or p0612.8 = 0:
p0605 is of significance for the rated temperature.
The following applies from firmware version 4.7 SP6 and p0612.8 = 1:
Overtemperature at the rated operating point.
- motor temperature model 2 (p0612.1 = 1):
Overtemperature at the rated operating point.
Dependency: For 1LA5 and 1LA7 motors (p0300 = 15, 17), 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 pre-assigned 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).
The signal is not suitable as a process quantity and may only be used as a display quantity.
Description: Defines the rated overtemperature of the squirrel cage rotor referred to ambient temperature in the motor
temperature model 2 (p0612.1 = 1).
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 pre-assigned 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 switched on.
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 temperature sensor is not being used (p0601).
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
