The difference with which p0352 was manually changed, must also be subtracted from reference parameter p0629 of
the Rs measurement.
Note: The parameter influences the temperature adaptation of the stator resistance.
The motor identification sets the cable resistance to 20% of the measured total resistance if p0352 is zero at the time
that the measurement is made. If p0352 is not zero, then the value is subtracted from the measured total stator
resistance to calculate stator resistance p0350. In this case, p0350 is a minimum of 10% of the measured value.
The cable resistance is reset when quick commissioning is exited with p3900 > 0.
Description: Sets the rotor/secondary section resistance of the motor at the ambient temperature p0625.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor data
identification routine (p1910).
Dependency: Refer to: p0625
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 parameter is not used for synchronous motors (p0300 = 2).
Description: Induction machine: sets the stator leakage inductance of the motor.
Synchronous motor: Sets the stator quadrature axis inductance of the motor.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor
identification routine (p1910).
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: If the stator leakage inductance (p0356) for induction motors is changed outside the commissioning phase (p0010 >
0), the magnetizing inductance (p0360) is automatically adapted to the new EMF (r0337). You are then advised to
repeat the measurement for the saturation characteristic (p1960).
For permanent-magnet synchronous motors (p0300 = 2), this is the non-saturated value and is, therefore, ideal for a
low current.
Description: Sets the stator direct-axis inductance of the synchronous motor.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor
identification routine (p1910).
Note: For permanent-magnet synchronous motors (p0300 = 2), this is the non-saturated value and is ideal for a low current.
