Function
Integral time constant of the torque and flux current control (d and q axis).
NOTE
Parameters P175t1, P175u1 are automatically computed and saved by performing the
autotune procedure I074 = 1: Control NO rot]. or I074= [2: Control YES rot].

Function
Current threshold for the compensation of positive and negative current
distortion. The positive current compensation equal to P175b x P175c
is
applied to positive current values exceeding the rated drive current multiplied
by the threshold set in P175a. The negative current compensation P175b
x
(100% - P175c) is
applied to negative current values having absolute values
greater than the rated drive current multiplied by P175a.
When lower currents
than the threshold currents are applied, compensation is obtained via linear
pattern. Null current means null compensation.
For tuning criteria, please refer to the FIRST STARTUP section.

Function
Compensation to suppress current distortion due to dead times. That
compensation activates when the positive current is greater than P175a (
in
respect to the rated drive current). See parameter P175a
for a detailed
description. For tuning criteria, please refer to the FIRST STARTUP section.
