Title:
ELEVATOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/021004
Kind Code:
A1
Abstract:
Provided is an elevator control device whereby a bus voltage can be automatically and appropriately set. This elevator control device is provided with: a power-supply-side current controller (9); a main circuit bus (10); an inverter (14); a regenerative resistance (12); a bus voltage controller (16); and a control unit (15) for detecting a first reference value of the bus voltage of the main circuit bus (10) when the bus voltage of the main circuit bus is the received voltage from a power supply, detecting a second reference value of the bus voltage of the main circuit bus (10) when the regenerative resistance (12) is on, and controlling the bus voltage controller (16) so that the value of the bus voltage of the main circuit bus (10) is between the first reference value and the second reference value.
