4.8 Motor characteristic parameter setting and automatic tuning
When the inverter runs in the "vector control" (P0-03=1) mode, it has a strong de-
pendence on the accurate motor parameters, which is one of the important differ-
ences from the "VF control" (P0-03=2) mode. In order for the inverter to have good
drive performance and operating efficiency, the inverter must obtain the accurate
parameters of the controlled motor.
The required motor parameters are (default motor 1 function code):

rotor inductance, etc. inside the motor
Tuning parameters
The methods for the inverter to obtain the internal electrical parameters of the con -
trolled motor include: dynamic identification, static identification, and manual input
of motor parameters.

Applies to asynchronous motors only. In the case where
it is difficult to separate the motor from the application
system, copy the parameters of the motor of the same
type that the inverter has successfully identified before
and input it into the corresponding function codes of P4-
