Abstract: The invention concerns an elevator and a method for energizing an elevator safety apparatus. The elevator comprises an elevator car (1), adapted for transferring passengers and/or cargo between landing floors (2); an elevator hoisting machine (3) for operating the elevator car (1); a drive unit (4) for driving the hoisting machine (3); and an elevator safety apparatus comprising at least one of a sensor (5), an indicator (6), a control unit (7) and an actuator (8) for ensuring safe elevator operation. The drive unit (4) is configured for delivering supply voltage to said elevator safety apparatus by controlling braking of the elevator hoisting machine (3) with a braking control mode designed for energizing the safety apparatus without need for an additional backup power supply, in case of an elevator power cut.

Abstract: The invention discloses a protection of an elevator and a method for protecting an elevator, in which the elevator comprises a machinery brake (7), a safety brake (8) of the elevator car (10), and an electrical drive (1) comprising an elevator motor (3) and a power supply appliance (2) of the elevator motor (3). The protection of the elevator comprises restriction of the output of the electrical drive (1) on the basis of the determined limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and restriction of the movement (12, 29) of the elevator car (10) on the basis of at least one determined limit value (13, 14, 30, 31, 32) for permitted movement of the elevator car (10). At least one limit value for permitted movement of the elevator car (10) is determined at least partly on the basis of the limit value (27, 28) for the stator voltage and/or the stator current of the elevator motor (3) and the elevator car (10) is fitted to move with a restricted movement during the restriction of the movement of the elevator car (10).
