ARRANGEMENT AND METHOD FOR OPERATING A STORAGE AND RETRIEVAL UNIT

摘要

A method and an arrangement for operating a storage and retrieval unit (3) are specified. A rail line (1) respectively a power supply rail (6) for the storage and retrieval unit (3) is set to a risk mode voltage, the rectified value/effective value of which lies below a minimum rectified value/minimum effective value necessary to move the storage and retrieval unit (3) but above zero, if a risk posed by the storage and retrieval unit (3) is detected. Alternatively or in addition, the voltage applied to the rail line (1)/power supply rail (6) can also be investigated in the storage and retrieval unit (3) for modulated change signals. The applied voltage is passed on to a traction motor (5) of the storage and retrieval unit (3) only when it has been established that the normal operation-traction voltage and not the risk mode voltage has been applied to the rail line (1)/power supply rail (6).

1. Method of operating a storage and retrieval unit (3) which can be moved on a rail line (1) and is supplied by a power supply (8) and/or a power supply rail (6) electrically connected to the rail line (1), by means of which at least one racking row (2) disposed alongside the rail line (1) can be accessed,whereinthe rail line (1)/power supply rail (6) is set to a risk mode voltage, the rectified value/effective value of which lies below a minimum rectified value/minimum effective value necessary to move the storage and retrieval unit (3) but above zero, if a risk posed by the storage and retrieval unit (3) is detected.
