SLVSCP6H July 2014 – June 2020 DRV10983
The DRV10983 aligns a motor by injecting dc current through a particular phase pattern which is current flowing into phase V, flowing out from phase W for a certain time (configured by AlignTime[2:0]). The current magnitude is determined by OpenLCurr[1:0]. The motor should be aligned at the known position.
The time of align affects the start-up timing (see Start-Up Timing). A bigger inertial motor requires longer align time.
