P1-00=2, the method is only applicable to the induction asynchronous motor load.
Pre-exciting the motor before starting can improve the fast response characterist-
ics of the asynchronous motor and meet the application requirements that require
a relatively short acceleration time. The frequency curve of the starting process is
as follows.

There are two stop modes of the inverter, namely deceleration stop and free stop,
which are selected by function code P1-13.
