    Abstract: A method and an arrangement for controlling a brake of an elevator. In the method a plurality of optional objectives of operation are determined for the elevator; one or more of these objectives is selected at a time to be implemented as an objective of the operation of the elevator by using selection criterion; references for the energizing current of the brake of the elevator that differ from each other and/or references for the closing current of the brake of the elevator that differ from each other are determined; the brake current reference used at any given time is selected so that the selected brake current reference best corresponds to an objective of the operation of the elevator to be implemented; and also the brake of the elevator is controlled by adjusting the brake current towards the selected brake current reference.

    Abstract: An arrangement and a method for supervising the operation of a brake includes a controllable electromechanical brake, including a magnetic circuit with at least two ferromagnetic parts fitted to move in relation to each other. A thrusting force is exerted between the ferromagnetic parts via a spring. The brake includes a magnetizing coil fitted into the magnetic circuit, for forming magnetic attraction between the parts of the brake. The arrangement includes a control of the brake, which includes at least one controllable switch, for adjusting the electricity supply of the magnetizing coil. The control of the brake comprises a supervision of the movement of the magnetic circuit of the brake.
