r0382 motor main inductance, transformed (gamma)

 

p0360 motor main inductance

 

p1590 flux controller P gain

 

p1592 flux controller integral action time

r1973 encoder pulse number identified

-

Note:

The encoder pulse number is only determined with a very high degree of inaccuracy (p0407/p0408) and is only suitable for making rough checks. The sign is negative if inversion is required (p0410.0).

-

p0410 encoder inversion actual value

Note:

If the encoder inversion is changed using MotID, fault F07993 is output, which refers to a possible change in the direction of rotation and can only be acknowledged by p1910 = -2.

Note:

The q inductance characteristic can be used as basis to manually determine the data for the current controller adaptation (p0391, p0392 and p0393).
