2.2 List of parameters
Dependency: Refer to: p0621, r0623
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.
Description: Displays the stator resistance determined using the Rs identification after switching on again.
Dependency: Refer to: p0621, p0622
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
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).
