Description:
During the Oriented Start-up Routine, the value adjusted in P0406 changes the parameters related to the motor
overload automatically, in the following manner:

Refer to the section 11.4 for more details on the use of option P0406=2 (Optimal Flux).
P0407 – Motor Rated Power factor
Refer to the section 10.2 for more details.
P0408 – Run Self-tuning
P0409 – Motor Stator Resistance (Rs)
P0410 – Motor Magnetizing current (i
P0411 – Motor flux Leakage inductance (σls)
P0412 – Lr/Rr constant (Rotor time constant – t
P0413 – t constant (Mechanical time constant)
m
Self-Tuning function parameters. Refer to the section 11.8.5.
11.7.1 adjustment of the Parameters P0409 to P0412 Based on the Motor Data
Sheet
Being in the possession of the motor equivalent circuit data, it is possible to calculate the value to be programmed
in the parameters from P0409 to P0412, instead of using the self-tuning to obtain them.
