2.2 List of parameters
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 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).
Note: For motor temperature model 1 (p0612.0 = 1), this parameter is not valid:
Description: Displays the stator winding temperature of the motor temperature model.
Dependency: Refer to: F07011, A07012, A07910
Description: Displays the rotor temperature of the motor temperature model (models 2 and 3).
Note: For motor temperature model 1 (p0612.0 = 1), this parameter is not valid:
Description: Sets the current limit.
Dependency: Refer to: r0209, p0323
Note: The parameter is part of the quick commissioning (p0010 = 1); this means that it is appropriately pre-assigned when
changing p0305. The current limit p0640 is limited to r0209.
The resulting current limit is displayed in r0067 and if required, r0067 is reduced by the thermal model of the power
unit.
