Abstract
A method and system for detecting and reporting component failures in a linear drive system may identify failed position sensors, failed position magnets, and failed drive coils in the linear drive system. As a mover travels along a track segment in the linear drive system, signals corresponding to the position of the mover and to the current commanded in each drive coil are stored. Analysis of the stored signals identifies whether one of the position sensors along the track segment, one of the position magnets on the movers, or one of the drive coils, used to propel the movers along the track, has failed.
