SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the excitation time of the motor for the stator resistance identification after powering up again (restart).
Dependency: Refer to: p0621, r0623
Note: For p0622 < p0346 the following applies:
If identification is activated, the magnetizing time is influenced by p0622. The speed is enabled after measurement
is complete, but not before the time in p0346 has elapsed (see r0056 bit 4). The time taken for measurement also
depends on the settling time of the measured current.
For p0622 >= p0346 the following applies:
Parameter p0622 is internally limited to the magnetizing time p0346, so that p0346 represents the maximum possi-
ble magnetizing time during identification. The entire measurement period (magnetizing plus measurement settling
time plus measuring time) will always be greater than p0346.
Description: Displays the identified stator resistance after the Rs identification after powering up again.
Dependency: Refer to: p0621, p0622
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 (refer to p0300), the parameter is pre-set as a function of p0307 and p0311.
Refer to: p0625
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (refer to p0300).
