NOTE!
 Every time that P0408 = 1 or 2:
The parameter P0413 (Mechanic time constant – Tm) will be adjusted to a value close to the motor
mechanic time constant. Therefore, the motor rotor inertia (table data valid for WEG motors), the
inverter rated voltage and current are taken into consideration.
 Vector mode with encoder (P0202 = 4):
When using P0408 = 2 (Run for I
load to the motor and set P0408 = 4 (Estimate T
case P0413 will also consider the driven load.
 VVW mode – Voltage Vector WEG (P0202 = 5):
In the VVW control self-tuning routine only the value of the stator resistance (P0409) will be obtained.
Therefore, the self-tuning will always be performed without rotating the motor.
 Better self-tuning results are obtained with the motor warm.

Estimated value and automatically adjusted 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).
