Abstract

A system for detecting linear drive system faults includes a track, a calibrated inspection apparatus, and processing circuitry. The track includes track segments defining a path along which movers travel. Drive coils induce travel of the movers along the track. The calibrated inspection apparatus includes (i) a calibrated inspection mover that travels along the track and/or (ii) a calibrated inspection station including one or more of the track segments. The processing circuitry obtains feedback signals from controllers for the track segments. The feedback signals characterize relative motion between the calibrated inspection apparatus and (i) the track segments and/or (ii) the movers. The processing circuitry determines a fault based on the feedback signals and calibrated characteristics of the calibrated inspection apparatus. The fault includes at least one of (i) a track segment fault in the track segments or (ii) a mover fault in the movers.
