Title:
PASSENGER CONVEYOR DEVICE AND CONTROL METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2016171699
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To decelerate and stop using the regenerative power of an inverter device at blackout.SOLUTION: On detecting blackout at an AC power supply 6, a control circuit 11 supplies a changeover signal to a changeover switch 12 to detach an inverter device 7 from a regenerative resistor 13 and to connect to the control circuit 11. The control circuit 11, based on inverter load information acquired from the inverter device, determines a predetermined deceleration to generate regenerative power to the inverter device, outputs a deceleration command to the inverter device, and decelerates and stops an electric motor 3 using, as a control power supply, the regenerative power generated at the inverter device by a deceleration operation according to the deceleration command.SELECTED DRAWING: Figure 1
