Output waveform
Inter-line voltage
Note: At startup, the motor is driven by a sine wave when the Hall signals are 5 Hz or higher (f
When driven by a sine wave, the motor is accelerated or decelerated according to the ON duty of T
the amplitude of the modulation symbol changes according to voltage V
