Abstract
A position-detection system for a drive having a rotor, which can move along a path, comprises an encoder unit, a signal-detection unit and a signal-processing device. The encoder unit or the signal-detection unit is arranged on the rotor, and the respective other unit is arranged along the path. Furthermore, the signal-processing device is designed to generate a first position signal and a second position signal on the basis of a relative position of the encoder unit and signal-detection unit. The signal-processing device is designed to determine a longitudinal position of the rotor along the path on the basis of phase values of the first and second position signals. Furthermore, the signal-processing device is designed to determine a distance, directed transversely with respect to the path, between the encoder unit and the signal-detection unit, on the basis of amplitude values of the first and second position signals, and to detect an operating state of the drive on the basis of the distance.
