Note
For p0622 < p0346 the following applies:
If identification is activated, the magnetizing time is influenced by p0622. The speed is enabled after measurement is
complete, but not before the time in p0346 has elapsed (see r0056 bit 4). The time taken for measurement also depends
on the settling time of the measured current.
For p0622 >= p0346 the following applies:
Parameter p0622 is internally limited to the magnetizing time p0346, so that p0346 represents the maximum possible
magnetizing time during identification. The entire measurement period (magnetizing plus measurement settling time
plus measuring time) will always be greater than p0346.
p0625[0...n] Motor ambient temperature during commissioning / Mot T_ambient
Access level: 3 Calculated: CALC_MOD_EQU Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: 21_1 Unit selection: p0505 Function diagram: 8017, 8018
Min:
-40 [°C] Max:
80 [°C] Factory setting:
20 [°C]
Description: Defines the ambient temperature of the motor for calculating the motor temperature model.
Dependency: See also: 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).
p0627[0...n] Motor overtemperature, stator winding / Mot T_over stator
Access level: 2 Calculated: CALC_MOD_EQU Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: MDS, p0130
Unit group: 21_2 Unit selection: p0505 Function diagram: 8017, 8018
Min:
15 [K] Max:
200 [K] Factory setting:
80 [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.
Dependency: For 1LA5 and 1LA7 motors (p0300 = 15, 17), the parameter is pre-set as a function of p0307 and p0311.

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).
The signal is not suitable as a process quantity and may only be used as a display quantity.
