P0410 – Motor Magnetization Current (I

Range:

Setting:

Properties:
Access groups
via HMI:
MOTOR
Description:
It is the motor magnetization current value.
It can be estimated by the self-tuning routine when P0408=2 (Run for I
m
) or obtained from an internal table
based 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
m
),
then adjust P0410 with a value equal to the motor no load current, before initiating the self-tuning.
For P0202=5 (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 (
σ
ls)
Adjustable
Range:
0.00 to 99.99 mH Factory
Setting:
0.00 mH
Properties:

MOTOR
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.
