SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description:
Sets the configuration for the thermal motor model.
Dependency:
Refer to: r0034, p0611, p0615
Note:
Re bit 00:
This bit is only used for permanent-magnet synchronous motors (p0300 = 2xx). It is only possible to switch in ther-
mal I2t monitoring with a time constant greater than zero (p0611 > 0).
Re bit 01:
This bit is used to activate/deactivate the thermal motor model for induction motors.
Description:
Sets the fault threshold for monitoring using the thermal I2t motor model.
Dependency:
The parameter is only used for permanent-magnet synchronous motors (p0300 = 2xx).
Refer to: r0034, p0611, p0612
Refer to: F07011, A07012
Caution:
This parameter is automatically preset for motors from the motor list (p0301).
When selecting a catalog motor, this parameter cannot be changed (write protection). Information in p0300 should
be carefully observed when removing write protection.
Description:
Sets the thermal adaptation of the stator/primary section resistance and rotor/secondary section resistance accord-
ing to r0395 and r0396.
Value:
0:
No thermal adaptation of stator and rotor resistances
1:
Resistances adapted to the temperatures of the thermal model
2:
Resistances adapted to the measured stator winding temperature
Note:
For p0620 = 1, the following applies:
The stator resistance is adapted using the temperature in r0035 and the rotor resistance together with the model
temperature in r0633.
For p0620 = 2, the following applies:
The stator resistance is adapted using the temperature in r0035. If applicable, the rotor temperature for adapting
the rotor resistance is calculated from the stator temperature (r0035) as follows:
theta_R = (r0628 + r0625) / (r0627 + r0625) * r0035
