Abstract
An elevator control device which can automatically and appropriately set a bus voltage. Therefore, the elevator control device includes a power supply side current controller, a main circuit bus, an inverter, a regenerative resistance, a bus voltage controller, and a control unit which detects a first reference value of a bus voltage of the main circuit bus when the bus voltage of the main circuit bus becomes a receiving voltage from a power supply, detects a second reference value of the bus voltage of the main circuit bus when the regenerative resistance is turned on, and controls the bus voltage controller so that a value of the bus voltage of the main circuit bus becomes a value between the first reference value and the second reference value.
