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).
Duration & sequence of the motor parameter identification
The duration of the motor parameter identification is approx. 30 s. The following steps are carried
out during this time:
1. The motor stator resistance (C084
) is measured.
2. The inverter error characteristic is measured.
3. The motor stator leakage inductance (C085
) is measured
4. The motor magnetising inductance (C092
) is measured
5. The motor magnetising current (C095
) is measured.
6. The V/f base frequency (C015
) is calculated.
7. The slip compensation (C021
) is calculated.
8. The V
min
boost (C016) is detected.

 Note!
Motor parameter identification may be aborted if a special motor (e.g. mid-frequency
motor) is used or if there is a large deviation between inverter and motor power.
Another cause for the abort of the motor parameter identification could be the implau-
sibility of the entered nameplate data, e.g. the entry P = 0 kW for the motor power.
