p0624[0...n] Motor temperature offset PT100 / Mot T_offset PT100
VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
Min
-100.0 [K]
Description: Sets the temperature offset for the PT100 measured value.
If there is a difference between the motor temperature displayed in r0035 and the actual motor temperature, this
offset can be entered in this parameter, thereby compensating for the difference.
Dependency: Refer to: p0600, p0601, p0602
Note: The parameter only takes effect with the following settings:
- Temperature sensor of the power unit detected (p0600 = 11).
- Sensor type PT100 selected (p0601 = 5).
If the resistance in series with the PT100 (e.g. the cable resistance of the feeder cable) is known, the following
conversion formula must be used:
Offset in p0624 = Measured resistance in ohms x 2.5 K/Ohm
Example:
Measured cable resistance = 2 Ohm
--> 2 Ohm x 2.5 K / Ohm = 5.0 K
p0625[0...n] Motor ambient temperature during commissioning / Mot T_ambient
VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: -
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
VECTOR_G Can be changed: C2(3), U, T
Data type: FloatingPoint32
P-Group: Motor
Not for motor type: PMSM, SESM, REL
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 1LA5 and 1LA7 motors (p0300 = 15, 17), 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).
