The lead angle can be corrected in the turn-on signal range from 0 to 28° in relation to the induced voltage.
Analog input from the LA pin (0 V to 4.3 V divided by 16):
Example Output Waveform
0 V = 0°
4.3 V or higher = 28°
If the V
WH) will perform 120° energization at a PWM that complies with the V
VL, WL) will operate at 120° energization, performing refresh operation based on the OFF timing.
(The same drive is executed during “headwind” operation as well.)
