1. A method for operating a conveyor comprising a drive unit (21) and a control unit (20) for controlling the drive unit, the drive unit comprising at least two drives (43, 44), the at least two drives being controlled by a control device (22) of the control unit, a rotary encoder (25, 35, 38, 49) of the control unit being connected to shafts (29, 42) of the drive unit of the conveyor each allocated to the at least two drives and registering a rotation of the shafts, a rotation angle signal or a rotational speed signal being transmitted to the control device by an encoder device (26, 39) of the corresponding rotary encoder in order to control the drives, the method including the step of determining via the control device a corresponding rotational speed of the shafts and comparing the rotational speed of the shafts to a referential rotational speed, and controlling the drives via the control device depending on the comparison; and
wherein the control device (22) defines or selects a referential acceleration according to a measured acceleration of one of the shafts.
