Vector Control
Description:
It is the motor magnetizing current value, which is automatically adjusted by the self-tuning
TUNING on page
Parameters P0409 to P0412 Based on the Motor Data Sheet on page
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
then 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.
