Abstract
A method of operating an elevator system with a drum for taking up a suspension device, a drive unit for driving the drum, and a control unit for controlling the drive unit, includes operating the control unit of the drive unit to prescribe a rotational speed that depends on a length of the suspension device that is rolled onto the drum. Also included is an elevator system in which the method can be used.
Claims12
A method of operating an elevator system with a drum for taking up a suspension means, a drive unit for driving the drum, and a control unit for controlling the drive unit, comprising the steps of:
- a. generating from the control unit a signal representing a rotational speed that depends on a length of the suspension means that is rolled onto the drum;
- and
- b. operating the drive unit at the rotational speed in response to the signal.
An elevator system comprising:
- a drum for taking up a suspension means attached to an elevator car;
- a drive unit for driving said drum in rotation;
- and
- a control unit for controlling the rotation of said drive unit, said control unit operating to determine a rotational speed for said drive unit that depends on a length of said suspension means that is rolled onto said drum.
