Abstract
A mover is configured to be electromagnetically propelled along a track in a linear motor track system with a force that is calculated to include compensation for gravity. A multi-axis accelerometer arranged in each segment of the track can detect an orientation or angle of the track segment for determining gravity with respect to the particular section. As a result, if the track is at an incline, such as a ramp, a desired force for moving a mover along the track can be compensated to include gravity due to the incline for achieving a desired motion result. In addition, the detected orientation of the track can be compared to an expected orientation stored by a control program to avoid a loss of performance due to physical changes in the track not matching an expected/programmed configuration of the track.
