Note: The reduction factor is only effective for p0610 = 12, and refers to the overtemperature.
Description: Sets the fault threshold for monitoring the motor temperature for motor temperature model 1 (I2t).
- Fault F07011 is output after the fault threshold is exceeded.
- fault threshold for r0034 = 100 % * (p0615 - 40) / (p0605 - 40).
Dependency: The parameter is only used for permanent-magnet synchronous motors (p0300 = 2xx).
Refer to: r0034, p0611, p0612
Refer to: F07011, A07012
Caution: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
Note: The hysteresis is 2 K.
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
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 iden-
tification (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 powered up for the first time (pulse enable) after booting
the Control Unit.
p0621 = 2:
Identification of the stator resistance every time the drive is powered up (pulse enable).
