Abstract: A method for detecting an overload condition of an elevator car of an elevator includes obtaining prevailing car-load information from a load weighing device arranged to weigh a prevailing car-load preferably when the elevator car is standing at a landing floor in an elevator shaft; determining if said prevailing car-load information fulfils one or more overload criteria; and generating a signal indicating an overload condition of an elevator car, if said car-load information fulfils one or more of said overload criteria; obtaining information of at least one operational parameter of the elevator; and adjusting one or more of said overload criteria or said car-load information based on said information of the at least one operational parameter of the elevator. An overload monitoring system and an elevator implementing the method are also disclosed.

Abstract: A drive device of an elevator includes a frequency converter to be connected to a public AC supply network and an elevator motor. The frequency converter includes a network rectifier configured to be connected to the AC supply network, a motor bridge to be connected to the elevator motor and a DC intermediate circuit located between the network rectifier and the motor bridge. The motor bridge is controlled by a control circuit which feeds the motor bridge with control pulses to regulate the motor speed. The drive device further includes at least one drive prevention circuit connected between the control circuit and the motor bridge. The drive prevention circuit is configured to obtain a safety signal from an elevator safety circuit includes two separate safety input circuits each configured to be connected to the elevator safety circuit to receive a safety signal. Each of the safety input circuits is configured to interrupt the connection between the control circuit and the motor bridge in response to the safety signal status.

Abstract: A method for controlling an elevator includes controlling the speed of a vertically moving elevator car during its run from a starting landing to a destination landing according to speed settings, the speed settings defining a constant target speed for the elevator car. The method includes obtaining measurement data of the ongoing run, which measurement data describes vertical speed and/or vertical acceleration of the vertically moving elevator car, determining whether the measurement data meets one or more predetermined criteria indicating unintended vertical speed and/or unintended vertical acceleration, and changing the speed settings of the current run by lowering the constant target speed from a first constant target speed to a second constant target speed if the measurement data meets said one or more predetermined criteria, continuing the run without intermediate stops to said destination landing. An elevator is provided to implement the method.
