7.1.12.1 Motor data identification - induction motor
Induction motor
The data are identified in the gamma equivalent circuit diagram and displayed in r19xx. The
motor parameters p0350, p0354, p0356, p0358 and p0360 taken from the MotID refer to the
T equivalent circuit diagram of the induction machine and cannot be directly compared. This
is the reason that an r parameter is listed in the table, which displays the parameterized
motor parameters in the gamma equivalent circuit diagram.

r1932 d Inductance r0377 Motor leakage inductance, total (gamma)
p0353 Motor series inductance
p0356 Motor leakage inductance
p0358 Motor leakage inductance
p1715 Current controller P gain
p1717 Current controller integral action time
r1934 q Inductance identified -
r1936 Magnetizing inductance identified 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 very imprecisely and is only suitable for making rough checks (p0408). 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.
