2.2 List of parameters
r0623 Rs identification stator resistance after switch on again / Rs-id Rs aft sw-on
Access level: 4
Can be changed: -
Unit group: -
Min
- [ohm]
Description: Displays the stator resistance determined using the Rs identification after switching on again.
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p0621, p0622
p0625[0...n] Motor ambient temperature during commissioning / Mot T_ambient
Access level: 3
Can be changed: C(3), U, T
Unit group: 21_1
Min
-40 [°C]
Description: Defines the ambient temperature of the motor for calculating the motor temperature model.
Dependency: Refer to: p0350, p0354
Note: The parameters for stator and rotor resistance (p0350, p0354) refer to this temperature.
If the thermal I2t motor model is activated for permanent-magnet synchronous motors (refer to p0611), p0625 is
included in the model calculation if a temperature sensor is not being used (see p0601).
p0626[0...n] Motor overtemperature, stator core / Mot T_over core
Access level: 4
Can be changed: C(3), U, T
Unit group: 21_2
Min
10 [K]
Description: Defines the rated overtemperature of the stator iron referred to ambient temperature in the motor temperature model
2 (p0612.1 = 1).
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
Refer to: p0625
Notice: When selecting a standard induction motor listed in the catalog (p0300 > 100, p0301 > 10000), this parameter is
automatically pre-assigned and is write protected. Information in p0300 should be carefully observed when removing
write protection.
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
p0627[0...n] Motor overtemperature, stator winding / Mot T_over stator
Access level: 2
Can be changed: C(3), U, T
Unit group: 21_2
Min
15 [K]
Description: Defines the rated overtemperature of the stator winding referred to the ambient temperature.
- motor temperature model 1 (I2t, p0612.0 = 1):
The following applies for firmware version < 4.7 SP6 or p0612.8 = 0:
p0605 is of significance for the rated temperature.
The following applies from firmware version 4.7 SP6 and p0612.8 = 1:
Overtemperature at the rated operating point.
- motor temperature model 2 (p0612.1 = 1):
Overtemperature at the rated operating point.
