Abstract
A level of thrust generated in a linear drive system is monitored by receiving an analog feedback signal at a controller from a position sensor mounted along a track for the linear drive system. The analog feedback signal varies as a function of a position of a mover traveling along the track, and the controller receives the analog feedback signal as the mover travels between a first position and a second position proximate the position sensor. An amplitude of the analog feedback signal corresponds to a value of thrust generated by the linear drive system for the mover. A change in the analog feedback signal from a nominal value of the analog feedback signal for the mover is detected as the mover travels between the first and second positions. Operation of the linear drive system is adapted when the change in the analog feedback signal exceeds a predefined threshold.
