Abstract
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.
