Preconditions
The motor parameters listed in the table below are excluded from automatic identification
and must therefore be adapted to the used motor before motor parameter identification
is carried out (see motor nameplate).
Furthermore, the available motor cable must be specified in terms of length and cross-
section:
Sequence of the motor parameter identification
1. The motor stator resistance (C00084
) is measured.
2. The inverter error characteristic is measured.
3. The motor stator leakage inductance (C00085
) is measured
For asynchronous motors only:
4. The motor magnetising inductance (C00092) and the motor rotor resistance (C00082)
are measured.
5. The motor magnetising current (C00095
) is measured.
6. The V/f base frequency (C00015
) is calculated.
7. Slip compensation (C00021
) is calculated.
8. V
min
boost (C00016) is detected.
