Siemens SINAMICS G120X - Mot_Temp_Mod 1 (I2 T) Fault Threshold; I2 T F Thresh; Thermal Resistance Adaptation Reduction Factor; Therm R_Adapt Red

Description: Sets the ambient temperature for motor temperature model 1 or 3.
- temperature model 1 (I2t, p0612.0 = 1):
For firmware version < 4.7 SP6 or p0612.12 = 0, the following applies:
The parameter is not relevant.
From firmware version 4.7 SP6 and p0612.12 = 1, the following applies:
The parameter defines the current ambient temperature.
- temperature model 3 (p0612.2 = 1):
The parameter defines the current ambient temperature.
Dependency: See also: p0612

p0614[0...n] Thermal resistance adaptation reduction factor / Therm R_adapt red
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: - Unit selection: - Function diagram: -
Min:
0 [%]
Max:
100 [%]
Factory setting:
30 [%]
Description: Sets the reduction factor for the overtemperature of the thermal adaptation of the stator/rotor resistance.
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: See also: 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 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: 21_1 Unit selection: p0505 Function diagram: 8017
Min:
0.0 [°C]
Max:
220.0 [°C]
Factory setting:
180.0 [°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).

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.
