Siemens G130 List Manual page 239

Dependency: The parameter is only used for motor temperature model 1 (I2t).
Refer to: r0034, p0611, p0612
Refer to: F07011, A07012
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: The hysteresis is 2 K.
p0616[0...n] Motor overtemperature alarm threshold 1 / Mot temp alarm 1
VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
Min
0.0 [°C]
Description: Sets the alarm threshold 1 for monitoring the motor temperature.
Note: The alarm threshold is not, as for p0604, coupled to the timer p0606. The hysteresis for canceling the fault is 2 K.
p0620[0...n] Thermal adaptation, stator and rotor resistance / Mot therm_adapt R
VECTOR_G Can be changed: C2(3), U, T
Data type: Integer16
P-Group: Motor
Not for motor type: -
Min
0
Description: Sets the thermal adaptation of the stator/primary section resistance and rotor/secondary section resistance according
to r0395 and r0396.
Value: 0:
1:
2:
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
For separately excited synchronous motors and p0620 = 1, p0620 = 2 is internally and automatically used for
calculating. There is no thermal model to adapt the damping resistances.
p0621[0...n] Identification stator resistance after restart / Rst_ident Restart
VECTOR_G (n/M) Can be changed: C2(3), T
Data type: Integer16
P-Group: Motor
Not for motor type: PMSM, SESM, REL
Min
0
Description: Selects the identification of the stator resistance after booting the Control Unit (only for vector control).
The identification is used to measure the actual stator resistance and from the ratio of the result of motor data
identification (p0350) to the matching ambient temperature (p0625) the actual mean temperature of the stator
winding is calculated. The result is used to initialize the thermal motor model.
p0621 = 1:
Identification of the stator resistance only when the drive is switched on for the first time (pulse enable) after booting
the Control Unit.
p0621 = 2:
Identification of the stator resistance every time the drive is switched on (pulse enable).
