Bydefault,AZdrivesarealwayssetto120‐degreephasing.Threephase(Brushless)drivesdo
howeverhaveasurface‐mountjumper(JE2)onthedrivePCBthatcanberemovedto
manuallysetthedriveto60‐degreephasing.
Using a Single Phase Motor with a Three Phase Drive ThreePhase(Brushless)
drivesarealsocompatiblewithSinglePhase(Brushed)motors.However,becausethereareno
HallSensorsonabrushedmotor,oneofthefollowingcourseofactionsmustbetakento
properlycommutatethedrive:
• RemovetheJE2jumpertosetthedrivefor60‐degreephasing.LeavealltheHallSensor
inputsonthedriveopen.Theseinputsareinternallypulledhighto+5V,creatinga"1‐1‐1"
