  • ELEVATOR SYSTEM
    Publication number: 20240059522
    Abstract: A third instruction determination unit determines a current instruction on the basis of a first current instruction determined by a first instruction determination unit (23) and a second current instruction determined by a second instruction determination unit (24). A brake control unit (25) controls a brake device (6) on the basis of the current instruction. The second instruction determination unit (24) determines the second current instruction so that the value of a current indicated by the current instruction determined by the third instruction determination unit increases stepwise when a brake switch (7) ceases to detect that the brake device (6) is in a non-braking state.
