The function is active only with a Sensorless mode. With a Sensorless mode the motor
speed is estimated.
The gains of this observer depend on the speed, on Motoring or Regen.
It is possible to set a Profile for the gains. In both operating areas (quadrants).
Each Profile is defined by three segments:
H = High - M = MedPoint - L = Low
For each segment it is possible to state the % Proportional Integral gain of the speed.
Each segment is linearly connected by two Bands from H to M, from M to L, and by two
Levels from H to M, from M to L.
In the configurations it is possible to set for each Profile (Motoring gains & Regen gains)
the gain values and the Band and Level values common to both Profiles.
Furthermore, in order to smooth the transition between Motoring and Regen, other two
parameters are used:
- E08.34 - Sls 0 tran bnd
Band in the speed 0 neighborhood, connecting the profiles linearly; the band
smoothes the change between one Profile
- E08.40 - Observer filter
Constant of the first-order Filter on both gains.
