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 identifica-
tion routine (p1910).
Note: For permanent-magnet synchronous motors (p0300 = 2), this is the non-saturated value and is ideal for a low cur-
rent.
Description: Sets the rotor/secondary section leakage inductance of the motor.
The value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor identification routine
(p1910).
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: If the rotor leakage inductance (p0358) for induction motors is changed outside the commissioning phase (p0010 >
0), then 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).
Description: Sets the magnetizing inductance of the motor.
This parameter value is automatically calculated using the motor model (p0340 = 1, 2) or using the motor identifica-
tion routine (p1910).
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: The parameter is not used for synchronous motors (p0300 = 2).
Description: The saturation characteristics (flux as a function of the magnetizing current) is defined using 4 points.
This parameter specifies the y coordinate (flux) for the 1st value pair of the characteristic.
Sets the first flux value of the saturation characteristic as a [%] referred to the rated motor flux (100 %).
Dependency: The following applies for the flux values:
p0362 < p0363 < p0364 < p0365
Refer to: p0366
Note: For induction motors, p0362 = 100 % corresponds to the rated motor flux.
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (refer to p0300).
