Table 4- 12 Data determined using p1910 for induction motors (stationary measurement)
Determined data (gamma)
r1912 identified stator resistance
r1913 rotor time constant identified
r1915 stator inductance identified
r1925 threshold voltage identified
r1927 rotor resistance identified
r1932 d inductance
r1934 q inductance identified
r1936 magnetizing inductance identified
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).

Note:
If the encoder inversion is changed using motor data identification, fault F07993 is output, which refers to a possible
change in the direction of rotation and can only be acknowledged by p1910 = -2.
Table 4- 13 Data determined using p1960 for induction motors (rotating measurement)
Determined data (gamma)
r1934 q inductance identified
r1935 q inductance identification current
Note:
The q inductance characteristic can be used as basis to manually determine the data for the current controller adaptation
(p0391, p0392 and p0393).

r1948 magnetizing current identified
r1962 saturation characteristic magnetizing current
identified
r1963 saturation characteristic stator inductance
identified
