The invention relates to a method for operating a conveyor means, in particular a hoist, a crane, a continuous conveyor or the like, and to a control unit, the conveyor means 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 drives being controlled by means of a control device (22) of the control unit, a rotary encoder (25, 38) of the control unit being connected shafts (29, 42) of the drive unit of the conveyor means each allocated to the drives and registering a rotation of the shafts, a rotation angle signal and/or a rotational speed signal being transmitted to the control device by means of an encoder device (26, 39) of the corresponding rotary encoder in order to control the drives, the control device determining the corresponding rotational speed of the shafts and comparing it to a referential rotational speed, the control device controlling the drives depending on the comparison.
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;
A control unit (20) for a conveyor comprising a control device (22) and at least two rotary encoders (25, 35, 38, 49), the rotary encoder being connectable to shafts (29, 42) of a conveyor allocated to a drive (43, 44) each of a drive unit (21) in order to register a rotation of the corresponding shaft, the rotary encoder comprising an encoder device (26, 39) for outputting a rotation angle signal or a rotational speed signal to the control device (22) in order to control the drive unit, wherein the corresponding rotational speed of the shaft is determinable and comparable to a referential rotational speed by the control device, the drives being controllable by the control device depending on the comparison;
