Abstract: A method and system for motion control of movers in an independent cart system is disclosed. In one implementation, the independent cart system includes a plurality of track segments, each section having a respective controller. One of the controllers receives a motion command for a plurality of carts, respectively. The controller generates a force command for each of the plurality of carts and transmits the respective commands to the track segments commutating the plurality of carts.

Abstract: An independent cart system with safety functions that prevent unintended motion independently within different sections of the track while permitting motion along other sections of the track is disclosed. A safety controller receives one or more input signals corresponding to operating conditions along the track. A safety program executing in the safety controller monitors the state of the input signals to determine whether a safety function is to be executed. When a safety program is executed, the safety controller transmits an output signal to one or more segment controllers present in one section along the track. Each segment controller is responsible for regulating current flow to the coils mounted to the corresponding track segment. In response to the signal from the safety controller, each segment controller in the section controls the power output to the coils along that section of track to achieve the safe operation desired in that segment.

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.
