5.1.2 Automatic motor data identification
The motor parameter identification serves to automatically identify the inverter characteristic, the
influences of the motor cable and various motor parameters.
Automatically identified motor parameters
Automatic calculation of the current controller and field controller parameters
From version 12.00.00 onwards: Following successful motor parameter identification, the current
controller and field controller parameters listed in the below table are calculated as well.
• If these parameters are not
to be calculated, bit 4 of C02865/1 must be set to "1".
 Note!
We strongly recommend motor parameter identification before the initial
commissioning of the sensorless vector control (SLVC) and the sensorless control for
synchronous motors (SLPSM).
