Abstract
The invention relates to a transport device (), in particular for transporting product carriers in a plant for manufacturing food products. The transport device () comprises at least one chain () to which measuring marks () are attached, an electrical drive system () for driving the chain () with a servo motor () and an absolute encoder (), a plant control unit () and a measuring sensor () for detecting the measuring marks () with a switching frequency of greater than 2000/s. The plant control unit () comprises a first input () for receiving measurement data from the measuring sensor () and a second input () for receiving position data from the position sensor () and is designed to receive data from the measuring sensor () and from the position sensor (), to mutually correlate said data correctly with respect to time, to determine therefrom lengths between measurement marks (), more particularly between two consecutive measurement marks, and to produce a signal which provides information about the quality of the chain. A servo position actual value is ascertained by means of oversampling.
