Abstract
A method and control unit for operating conveyor means, the conveyor means comprising a drive unit, a control unit, a carriage moved along a rail by the drive unit, the control unit being controlled by a control device, a rotary encoder connected to a shaft of the drive unit or of a measuring wheel of the carriage and registering a rotation of the shaft, a rotation angle signal and/or a rotational speed signal being transmitted to the control device by an encoder device to determine an assumed position of the carriage on the rail. At least one position signal is detected by a sensor apparatus disposed on the carriage and the rail, a real position of the carriage on the rail being determined using the position signal by a safety apparatus, the assumed position being corrected according to the real position by the safety device.
