Output waveform
Inter-line voltage
Note: The motor is driven by a sine wave if REV = High-Z, i.e., if the Hall signals at start-up are 5 Hz (fosc = 4 MHz)
When driven by a sine wave, the motor is accelerated or decelerated according to the On duty of T
when the amplitude of the modulation symbol changes by voltage V
