Abstract: In a method for performing a manual drive in an elevator after mains power-off, the frequency converter of the motor is separated from mains, any safety blocking of the brake drive and/or motor drive is disabled, current is supplied from the battery to the brake drive to open the elevator brake and current is supplied from the battery to the drive control to allow regulation of the motor speed via the inverter bridge, the manual drive control observes the motor speed via the speed sensor and starts a speed feedback loop to regulate the motor speed to a manual drive reference value by feeding a three phase-AC current to the motor windings via the semiconductors of the inverter bridge, which manual drive speed reference is lower than the speed reference for normal elevator operation, when the car reaches a floor level the floor level indicator is activated, and the actuator is released whereafter the current supply from the battery to the elevator brake is interrupted and the previous disabled safety blocking of the brake drive and/or motor drive is enabled again,

Abstract: This invention relates to a method for defining absolute position information of an elevator car. The method comprises: obtaining continuously a pulse position information of the elevator car; and defining an absolute position information of the elevator car by adding a predefined correction value to the obtained pulse position information of the elevator car. The predefined correction value indicates a drift between the obtained pulse position information of the elevator car and the actual pulse position of the elevator car. The invention also relates to a safety control unit and an elevator system performing at least partly the method.

Abstract: According to an aspect, there is provided an elevator communication system including a communication bus applying a master-slave protocol, a master node connected to the communication bus and at least one slave node connected to the communication bus. The master node and the at least one slave node are configured to apply, for data communication in the communication bus, a repeating frame structure in which a first time slot of a frame is reserved for the master node and in the remaining time slots of the frame each slave node of the at least one slave node has a dedicated time slot. The master node is configured to extend the time between consecutive frames in order to enable a power saving mode for the communication bus.

Abstract: An elevator includes a car, a counterweight, and a hoisting member connecting the car with the counterweight over a traction sheave. A free fall protection system includes a free fall protection controller, a free fall protection member connecting the car with the counterweight over the traction sheave or over a separate free fall sheave. The car and the counterweight are supported by the hoisting member in normal operation and by the free fall protection member only in a situation in which the hoisting member support fails. At least one free fall protection brake is arranged to stop the movement of the free fall protection member and thereby also the movement of the car and/or the counterweight, when being activated by the free fall protection controller.
