Timing Chart of the Counterclockwise Rotation
(Hall Signal Input for Counterclockwise Rotation)
0 < Hall signal frequency < 5 Hz
(120° commutation)
5 Hz < Hall signal frequency
(180° commutation: Modulated wave inside the IC)
The timing chart may be simplified for the sake of brevity.
*: The lead-angle correction is performed in accordance with the LA input when the Hall signal frequency is 2.5 Hz or
higher.
