9. Lead Angle
Lead angle of the conducting signal can be set in the range of 0 to 22.5° against the hall signal.
Lead angle is set by analog input of LA pin (The range of 0 to VADC is divided into 32 steps and lower 17 steps
are used.)
LA = 0V
→ Lead angle 0°
LA = VADC → Lead angle 22.5° (In case of inputting the voltage of VADC or more.)
