The value is a starting value when switching on. Internally, after switch-on, the reduction factor has no effect
corresponding to the thermal time constant.
Dependency: Refer to: p0610
Note: The reduction factor is only effective for p0610 = 12, and refers to the overtemperature.
p0615[0...n] Mot_temp_mod 1 (I2t) fault threshold / I2t F thresh
Access level: 2
Can be changed: C(3), U, T
Unit group: 21_1
Min
0.0 [°C]
Description: Sets the fault threshold for monitoring the motor temperature for motor temperature model 1 (I2t).
The following applies for firmware version < 4.7 SP6:
- fault F07011 is output after the fault threshold is exceeded.
- fault threshold for r0034 = 100 % * (p0615 - 40) / (p0605 - 40).
The following applies from firmware version 4.7 SP6 and p0612.8 = 1:
- the fault threshold in p0615 is preset when commissioning.
- when a catalog motor with motor temperature model 1 (I2t) is being commissioned for the first time, the threshold
value is copied from p0615 to p5391.
- p5391 is of significance for evaluating the fault threshold.
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.
p0620[0...n] Thermal adaptation, stator and rotor resistance / Mot therm_adapt R
Access level: 4
Can be changed: C(3), U, T
Unit group: -
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
p0621[0...n] Identification stator resistance after restart / Rst_ident Restart
Access level: 2
Can be changed: C(3), T
Unit group: -
Min
0
Description: Selects the identification of the stator resistance after booting the Control Unit (only for vector control).
