Table 3-12 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).
r1936 magnetizing inductance identified
r1948 magnetizing current identified
r1962 saturation characteristic magnetizing current
identified
r1963 saturation characteristic stator inductance
identified
Note:
The magnetic design of the motor can be identified from the saturation characteristic.
r1969 moment of inertia 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).
