0~2
1
0: No judgment No load starting capability, requiring long acceleration time.
1: DC injection starting Incrementally inject DC current to (P15.05* motor rated current), and drag
the motor magnetic pole to the excitation direction.
2: Pulse voltage injection starting Inject voltage pulses to conduct initial magnetic pole judgment.
