Description:
It is the value estimated by the self-tuning.
Note!
The P0409 setting determines the value of the current regulator integral gain P0168. The parameter
P0168 is recalculated every time the content of P0409 is modified via keypad (HMI).

Description:
It is the motor magnetizing current value.
It can be estimated by the self-tuning routine when P0408=2 (Run for I
in standard WEG motors, when P0408=1 (No rotation).
When a standard WEG motor is not used and it is not possible to run the self-tuning with P0408=2 (Run for I
adjust P0410 with a value equal to the motor no load current, before initiating the self-tuning.
For P0202=4 (vector mode with encoder), the value P0410 determines the motor flux, therefore it must be properly
adjusted. If it is low, the motor will operate with a reduced flux compared to the rated condition, having, consequently,
its torque capability reduced.
P0411 – Motor flux Leakage inductance (σls)

via HMI:
Description:
It is the value estimated by the self-tuning.
The P0411 setting determines the current regulator proportional gain.
Note!
When adjusted via the keypad (HMI), this parameter may change the parameter P0167 automatically.
